Introduction

CitruSmart is a natural food ingredient derived from upcycled citrus peels – the fibrous byproduct of citrus juice production[1]. Developed by Nexus Ingredient, CitruSmart is a clean-label citrus fiber designed to replace many synthetic additives in foods. It consists of 100% citrus fiber with no chemical modifications or added ingredients[2]. This sustainable, plant-based ingredient carries the simple designation “citrus fiber” on labels (no E-numbers), aligning with consumer demand for recognizable ingredients and waste valorization of citrus peel sidestreams[3][1]. CitruSmart is positioned as a versatile texture and stability solution for food formulators – capable of improving viscosity, binding water, and enhancing mouthfeel across a broad range of products from bakery goods to dairy, sauces, and plant-based meat alternatives[4][5]. In the following sections, we detail CitruSmart’s technical composition, multi-functional properties, performance under various conditions, application highlights, and its advantages in replacing synthetic stabilizers – all framed for R&D and innovation teams seeking natural ingredient solutions.

Technical Composition and Properties of CitruSmart

CitruSmart is composed entirely of dietary fiber extracted from citrus fruit peels. This fiber is roughly 80% total fiber by weight, comprising approximately 40–45% insoluble fiber (cellulose, hemicellulose, lignin) and 40–45% soluble fiber (primarily pectin) with residual moisture and ash[6][7]. The high pectin content is key – pectin is a natural hydrocolloid conferring gelling and emulsifying functionality without any chemical derivatization. The ingredient appears as an off-white powder and is typically standardized to food-grade specifications: for example, ash content ≤5% and a pH of 3.0–8.0 (1% dispersion)[2]. Because CitruSmart is minimally processed (no solvents or chemical modification in its standard production), it retains native emulsifying properties and an intact fiber matrix[8].

Key Functional Attributes: CitruSmart has an exceptionally high capacity for water and oil retention due to its fibrous, porous microstructure. It can bind roughly 10–15 times its weight in water (Water Holding Capacity, WHC) and over 1.5 times its weight in oil (Oil Holding Capacity, OHC), depending on the grade and conditions[9]. This means a small addition of CitruSmart significantly increases a formulation’s water-holding ability and imparts richness by trapping oils. The citrus fiber particles also contribute to viscosity and network formation in mixtures, giving CitruSmart inherent thickening power and stabilizing ability. With over two-thirds of its composition as soluble and insoluble fiber, CitruSmart effectively boosts a product’s dietary fiber content as well[10]. Table 1 summarizes some key technical specifications of CitruSmart:

Table 1: Composition and key properties of CitruSmart (citrus fiber).

These compositional features underpin CitruSmart’s broad functionality – essentially acting as a multi-functional hydrocolloid originating from a single clean-label source.

Multi-Functional Properties of CitruSmart

CitruSmart exhibits several functional properties that traditionally require a combination of synthetic gums, starches, or emulsifiers. By leveraging its high fiber and pectin content, CitruSmart can perform as:

• Water-Binding & Moisture Retention: CitruSmart’s fiber matrix strongly binds water, significantly reducing water activity and locking moisture into food matrices[9]. This property helps products stay fresher for longer, preventing drying or staling. In bakery and snack products, for example, added citrus fiber controls moisture migration and extends soft texture over shelf-life[15]. The superior water retention also translates to increased yield in formulations – meats and doughs retain more weight after cooking or baking due to less moisture loss[9]. By holding water, CitruSmart can replace humectants or synthetic polyphosphate salts traditionally used to retain moisture in processed foods.
• Emulsification: Thanks to the presence of native pectin and fine insoluble particles, CitruSmart acts as a natural emulsifier and stabilizer. It can facilitate oil-in-water emulsion formation and stability in products like dressings, mayonnaise, sauces, and meat emulsions[16]. The citrus fiber particles physically encapsulate oil droplets while pectin provides a stabilizing colloidal network, preventing phase separation. In fact, citrus fiber ingredients have demonstrated emulsifying performance comparable to or better than conventional emulsifiers: for instance, Citri-Fi (a similar citrus fiber) can stabilize 1.2–1.7 times more oil than mono- and diglyceride emulsifiers, and 2–3 times more than lecithin in bakery systems[17]. This emulsifying power translates to improved creamy texture and mouthfeel, as noted in applications from ice cream to sauces[18]. CitruSmart allows formulators to achieve smooth, stable emulsions naturally, reducing the need for added lecithins, egg yolks, or other emulsifying agents.
• Thickening & Texturizing: CitruSmart substantially improves viscosity and texture in various food matrices[18]. Dispersed citrus fiber particles swell with water and interlock to increase the viscosity of liquids and semi-solids. The result is enhanced body and mouthfeel in products ranging from beverages and soups to batters and doughs. CitruSmart can function similarly to hydrocolloid gums (like xanthan or guar) or modified food starches as a thickener – but with the advantage of being a single natural ingredient. Even at low usage levels (often <1% in formula), it contributes noticeable thickening. This property is especially valuable in low-fat or reduced-sugar formulations where added thickness can mimic the richness of fats or the viscosity of sugar syrups. By improving rheology and preventing ingredient settling (in beverages or sauces), CitruSmart ensures a uniform, pleasant texture without “gummy” or slimy characteristics.
• Gelling (Structure Formation): Under certain conditions, CitruSmart also exhibits gelling behavior. In particular, dairy and protein-rich systems activate CitruSmart’s pectin to create a soft gel network[19]. Nexus Ingredient offers a dairy-specific grade of CitruSmart that is specially processed to provide gelling, water retention, and thickening in the presence of milk proteins[19]. The natural pectin in citrus fiber can interact with calcium in dairy (or added calcium ions) and with dairy proteins to form a gelled structure, improving the body of yogurts, dairy beverages, and cheeses. While not a firm gel like carrageenan, this contributes to a creamy, spoonable consistency and prevents phase separation (e.g. whey syneresis in yogurt). Even in non-dairy plant-based gels, citrus fiber can aid structure when used alongside other gelling agents (e.g. agar or starch). Overall, CitruSmart’s gelling and thickening functionality in protein or low pH environments broadens its use to products where set or stabilized textures are desired (puddings, custards, vegan “gelatin” replacements, etc.)[10].

Stability Across Processing Conditions

A crucial advantage of CitruSmart is its robustness under various processing and storage conditions. Many hydrocolloids or emulsifiers have narrow conditions for optimal function (for example, some gums lose viscosity under high heat or extreme pH). CitruSmart’s natural fiber network remains functional in a wide range of scenarios:

• Heat Stability: CitruSmart tolerates high-temperature processing (e.g. pasteurization, retort cooking, baking) without breaking down. The citrus fibers do not dissolve or hydrolyze easily with heat, meaning viscosity and emulsion stability are largely maintained through cooking. This makes CitruSmart suitable for products that undergo cooking or baking (breads, baked bars, retorted sauces) where synthetic thickeners might degrade. Its functional performance remains stable, helping to maintain texture after heating[20].
• pH Tolerance: Formulations ranging from acidic to neutral pH can incorporate CitruSmart effectively. Citrus fiber’s functionality is preserved in low pH environments like yogurt, fruit beverages, and dressings (pH 3–4), as well as in neutral systems like bakery batters or meat emulsions[2][20]. Unlike some proteins or modified starches that might precipitate or lose viscosity at low pH, CitruSmart’s pectin content is actually activated by mild acidity (aiding hydration and gelation), while the insoluble fiber portion remains unaffected. This broad pH stability (roughly pH 3.0 up to 7–8) gives formulators flexibility to use it in sour dressings, sauces, and fruit preparations without needing different stabilizers for different pH ranges.
• Freeze–Thaw Stability: Products destined for freezing (ice creams, frozen baked goods, frozen meals) benefit from CitruSmart’s ability to control water. By tightly binding water, CitruSmart reduces the amount of free water that can form ice crystals, thereby mitigating textural damage upon freezing and thawing. It helps prevent syneresis (water separation) after freeze–thaw cycles and maintains emulsion stability in frozen desserts and sauces[21][20]. For example, in ice cream CitruSmart can improve freeze–thaw tolerance and creaminess by limiting ice crystal growth and trapped-air collapse. This natural freeze–thaw stability often allows replacement of additives like mono- and diglycerides or guar gum that are added specifically to address freeze–thaw issues in frozen foods[20].
• Shear and Process Resilience: CitruSmart is added as a powder and can withstand typical mixing and shear conditions during production. High-shear mixing can even enhance its functionality by dispersing fibers more uniformly. The ingredient is effective in both cold-process applications (e.g. cold emulsified dressings) and hot-process ones (soups, sauces), giving formulators process flexibility. Its stability under normal storage conditions (ambient dry storage for at least 18–24 months) is well established[22][23], meaning a reliable shelf life for both the ingredient itself and the finished products it stabilizes.

By offering heat, pH, and freeze/thaw stability in one, CitruSmart serves as a single-solution stabilizer across diverse product conditions, reducing the need for multiple specialty additives.

Application Highlights of CitruSmart

CitruSmart’s multi-functionality lends itself to a wide spectrum of food and beverage applications. Below we highlight key application categories (as featured by Nexus Ingredient and industry usage) and the benefits CitruSmart provides in each:

Bakery and Baked Goods

In bakery formulations, CitruSmart improves both processing and finished product quality. Its water-binding capacity yields softer doughs and batters that are easier to machinize and less prone to drying out. For example, in breads, buns, cakes, and muffins, adding 0.3–1% citrus fiber can increase dough hydration and extensibility, which improves oven spring and crumb tenderness. CitruSmart acts as a dough conditioner by enhancing dough machinability and gas retention, similar to what mono- & di-glyceride emulsifiers or DATEM would do, but through natural fiber action. In the finished baked goods, the retained moisture leads to a soft crumb and extended shelf-life: products stay moist and do not stalify quickly[24]. One study noted that citrus fiber extended the freshness of sweet and savory baked goods by reducing moisture loss over time[8][24]. Additionally, CitruSmart enables fat reduction in bakery by mimicking some of the lubricant and tenderizing effects of fats. It can replace a portion of shortening or oil in recipes, resulting in lower calorie products while maintaining a rich mouthfeel[9]. Importantly, CitruSmart is gluten-free and thus particularly useful in gluten-free baking, where its structure-building and water-holding help compensate for the lack of gluten. It contributes to a better crumb structure and less crumbling in gluten-free breads and cakes, often reducing the need for xanthan gum or other gum additives. Overall, CitruSmart boosts yield (due to less bake-out weight loss), prolongs freshness, and improves texture in baked goods ranging from breads and tortillas to cookies and pastry. Bakers can label it simply as citrus fiber, appealing to clean-label seekers in the bakery aisle.

Dressings and Sauces

CitruSmart performs exceptionally in emulsified dressings, condiments, and culinary sauces by providing natural thickness and emulsion stability. In mayonnaise and creamy dressings (e.g. ranch, Caesar, plant-based mayo), CitruSmart helps emulsify the oil and water phases, reducing or even eliminating the need for egg yolk or traditional emulsifiers. A natural citrus fiber like CitruSmart has been shown to maintain stable emulsions and prevent separation in mayonnaise-style dressings, even through temperature fluctuations and freeze–thaw cycles[16]. It also contributes to the desired viscosity and cling in dressings – delivering a rich, creamy texture without resorting to modified starches. In acidic sauces (vinaigrettes, marinades) CitruSmart’s pH tolerance ensures that it remains effective as a thickener and suspending agent for herbs or spices. For cooking sauces and gravies, the fiber adds body and glossy appearance, and because it is heat-stable, the viscosity it provides will hold up during simmering or reheating. CitruSmart can replace or reduce use of common sauce thickeners like modified corn starch, carrageenan (in dairy-based sauces), or xanthan gum. Notably, its contribution to mouthfeel is often described as more natural and palate-pleasing (less slimy) than some gums, with a clean flavor release (citrus fiber itself has minimal taste or odor). In applications like tomato-based sauces, citrus fiber’s water-binding curbs water separation (“wet pocket” formation) on plate or pizza, acting similarly to tomato paste but as an added fiber source. In summary, CitruSmart allows formulators to achieve stable, thick dressings and sauces with a simpler ingredient label, all while improving texture and freeze/thaw robustness[20][16].

Dairy Products and Plant-Based Dairy Alternatives

CitruSmart is highly beneficial in dairy applications such as yogurt, cheese spreads, ice cream, and flavored milk, as well as in plant-based dairy alternatives (like almond/soy milks, vegan yogurts and desserts). In yogurt and fermented dairy drinks, CitruSmart serves as a natural texturizer that increases viscosity and prevents whey separation. It can supplement or replace traditional dairy stabilizers like pectin, gelatin, or modified starch. Because a special grade of CitruSmart is optimized to interact with milk proteins, it provides gelling and thickening in the presence of dairy proteins[10]. This means Greek-style yogurts or drinkable yogurts can attain a creamy, stable consistency and improved water-holding (no synersis) by including citrus fiber. In cheeses and cheese analogues, CitruSmart’s binding ability can improve sliceability and reduce cooking loss (e.g. less liquid released in a heated cheese sauce or vegan cheese).

For ice cream and frozen dairy desserts, CitruSmart offers multiple advantages. It improves the mix viscosity and aids in air incorporation and stability (overrun), leading to a smoother body. During freezing, its water-holding helps depress ice crystal growth, contributing to a creamy, non-icy texture. CitruSmart can replace part of the locust bean gum, guar gum, or mono-glycerides often used in ice creams to manage meltdown and texture, while enabling an “all-natural” stabilizer system. The ingredient’s functionality is not limited to true dairy: in plant-based milks and yogurts, citrus fiber helps suspend plant protein solids (prevent sedimentation in e.g. almond milk), adds thickness to mimic dairy’s mouthfeel, and provides emulsification for added oils or flavors. A clean-label citrus fiber is especially valuable here to replace gums (many of which are considered processed additives by consumers) in products marketed as plant-based and wholesome. CitruSmart’s neutral taste allows it to fortify dairy alternatives with fiber and improve texture without altering flavor. Nexus reports successful uses of CitruSmart in yoghurts, shakes, ice creams, and even cheese formulations, significantly enhancing water retention and texture in these milk or plant protein-based systems[25]. All told, CitruSmart helps dairy and alternative-dairy manufacturers create indulgent textures and stable products while meeting clean-label, vegetarian, and allergen-free requirements.

Meat and Plant-Based Meat Products

One of the most impactful application areas for CitruSmart is in processed meat products and meat alternatives. In traditional processed meats (sausages, cold cuts, pâtés, etc.), citrus fiber acts as a high-performance binder and moisture retainer. It can replace phosphates (E-numbers like sodium tripolyphosphate) that are typically added to increase water-binding in ham and sausage[26]. By incorporating CitruSmart, manufacturers can maintain or improve yield and juiciness of meat products while declaring only citrus fiber on the label. The fiber’s ability to hold water and fat means less cooking loss – for example, in a sausage or beef patty, there will be reduced shrinkage and a succulent bite due to retained juices. Citrus fiber also contributes to a firmer, cohesive structure in products like frankfurters or meatballs, thereby substituting for binders like carrageenan or modified starch. In fact, citrus fiber has been used to successfully replace carrageenan in certain meat formulations, offering comparable texture and sliceability[26]. Since CitruSmart is heat-stable, it withstands cooking processes (grilling, baking, retorting) without breaking down, ensuring the product remains moist and bound together.

In the rapidly growing field of plant-based meat, CitruSmart provides a critical clean-label alternative to synthetic binders. Many vegetarian/vegan burgers and sausages have relied on methylcellulose – a synthetic hydrocolloid – for its unique thermal gelling that holds plant patties together when cooked. CitruSmart offers an appealing natural replacement for methylcellulose in these applications[1]. As part of a formulation strategy (often used in combination with other natural binders like starch, agar, or proteins), citrus fiber helps form a matrix that keeps plant-based burgers intact during cooking, then releases moisture and fat for a juicy, meat-like result[27]. Fiberstar, a citrus fiber supplier, notes that citrus fiber (as a juicing byproduct) can successfully bind plant-based meats and provide the “burst of juiciness” and sizzle that consumers expect in a burger[28][27]. CitruSmart’s contribution here is twofold: it physically stabilizes the mix (preventing crumbling) and it retains water/oil that later yields succulence. This addresses the key challenge in meat alternatives of replacing methylcellulose with a consumer-friendly ingredient while maintaining functional performance. Furthermore, adding citrus fiber boosts the fiber content of meat analogues, aligning with nutritional goals. Whether in a pea-protein burger or a soy-based sausage, CitruSmart helps achieve a moist, cohesive texture and cleaner label. It is typically used at a few percentage points in plant-meat formulations (often 1–3%, depending on synergy with other binders) and can be labeled simply as citrus fiber or dried citrus pulp[14]. This simplicity in labeling, combined with its efficacy, makes CitruSmart highly attractive to innovators in the plant-based protein space.

Other Applications (Beverages, Snacks, and More)

Beyond the major categories above, CitruSmart finds utility in many additional applications:

• In beverages and powdered drink mixes, CitruSmart can function as a natural bodying agent and stabilizer. For example, in smoothies, high-protein shakes, or juice-based drinks, a small addition of citrus fiber imparts a pleasing viscosity and keeps particulates (like cocoa, protein, or juice pulp) suspended uniformly. It can also improve the mouthfeel of reduced-sugar beverages that might otherwise feel thin. Since it is flavor-neutral and dispersible, it integrates well into beverage processing and can even help stabilize foams in specialty drinks. CitruSmart’s fiber is also prebiotic in nature, which could be an added nutritional marketing point in wellness beverages (though its primary purpose is functional rather than as a supplement).
• In snack bars, protein bars, and cereal bars, CitruSmart works as a binder to hold ingredients together and retain softness. It can reduce the need for sugary binders or syrups by keeping bars moist and less prone to hardening over time. Its humectant-like fiber properties help extend shelf life in bars, preventing them from drying out. Additionally, incorporating citrus fiber in fruit-filled cereal bars or pastries can prevent the filling from boiling out or becoming too firm, by controlling water activity.
• In confectionery and fruit preparations, CitruSmart’s pectin content can assist or partially replace added pectin or gelatin. For instance, in jams, fruit spreads, or pie fillings, citrus fiber adds thickness and stability, potentially reducing sugar and pectin requirements while improving nutritional fiber content. As a plant-based ingredient, it can complement or replace gelatin in some gummy or jelly formulations for a cleaner label vegan option, although it usually works alongside other gelling agents for confectionery textures.
• In pet foods and specialty products, the same benefits (water binding, emulsification, fiber enrichment) apply. Upcycled citrus fiber is sometimes used in premium pet food to improve texture and moisture retention while boosting fiber intake for pets.

In summary, CitruSmart’s applicability is broad; it has been successfully used in products ranging from ice creams to breads, from beverages to processed meats[4]. Formulators in virtually any sector can consider this multi-functional citrus fiber when looking to simplify ingredient lists and enhance product quality naturally.

Replacing Synthetic Stabilizers and Emulsifiers

A primary motivation for using CitruSmart is its ability to replace or reduce synthetic and chemically modified ingredients (the “E-numbers” and additives) while maintaining product performance. CitruSmart serves as a clean-label alternative to many conventional stabilizers, emulsifiers, and thickeners, such as:

• Xanthan Gum (E415) and Guar Gum (E412): These microbial and plant gums are common thickeners/stabilizers in dressings, sauces, and gluten-free baking. CitruSmart can often eliminate the need for xanthan or guar by providing equivalent viscosity and stability naturally[20]. For example, in gluten-free bread, using citrus fiber allowed removal of xanthan gum with no loss in dough functionality[20]. Unlike xanthan, citrus fiber yields a cleaner mouthfeel and can be simply labeled as fiber.
• Carrageenan (E407): Used in dairy products (chocolate milk, ice cream) and some processed meats for gelling and stabilization, carrageenan has faced clean-label scrutiny. CitruSmart offers a carrageenan-free solution by imparting thickness and preventing separation in dairy systems[26]. It may not form as firm a gel as carrageenan alone, but in many cases it can achieve the needed viscosity and suspension, especially when combined with dairy proteins or other gums, without the need for this artificial additive.
• Methylcellulose (E461): A key binder in many plant-based meats and some bakery items, methylcellulose is synthetically produced and not kitchen-friendly. Citrus fiber has emerged as one of the most promising natural replacements for methylcellulose in meat analogues[1]. By using CitruSmart (often alongside other natural hydrocolloids like agar or starch), formulators can create plant-based burgers and sausages that hold together and juicily gel upon cooking, while avoiding methylcellulose on the label[27]. This directly addresses consumer and retailer calls to remove methylcellulose from vegan products in favor of recognizable ingredients.
• Mono- & Di-Glycerides (E471) and DATEM (E472e): These emulsifiers are commonly added in bakery (breads, cakes) and dairy (whipped toppings) to improve texture and extend shelf life. CitruSmart can replace such mono- and diglycerides by naturally enhancing emulsification and crumb softness. In trials, citrus fiber achieved equal or better oil stabilization in bread than monoglyceride emulsifiers[17], enabling their removal. Likewise, in ice cream, CitruSmart’s emulsifying and water-holding effects can substitute for mono/diglycerides or DATEM to maintain overrun and slow melting, all with a cleaner label[20].
• Starches and Gels (Modified Starch, CMC, etc.): Modified food starches and cellulose gum (CMC) are broadly used to thicken or gel foods but appear as complex additives on labels. CitruSmart’s pectin-rich fiber can reduce reliance on modified starch in products like sauces and fillings by contributing viscosity and stability. It has been described as a natural hydrocolloid system in itself, capable of replacing pectin or starch partially in certain bakery fillings and jams[20]. Additionally, Nexus’s own Unifier® product (a blend of vegetable fibers) demonstrates that natural fiber systems can replace carboxymethyl cellulose (CMC) and other E-number stabilizers across the board[29]. CitruSmart, as a single-ingredient solution, embodies that philosophy in a focused way.

In essence, CitruSmart enables formulators to remove many “artificial” or unloved additives (gums, gels, emulsifiers) from ingredient lists. It delivers the functional benefits—thickening, binding, emulsifying, moisture control—that these additives provided, but does so with a consumer-friendly label. This simplifies product formulations and aligns with clean-label standards without sacrificing quality. By substituting a synthetic stabilizer with CitruSmart, companies can often achieve “no artificial additives” claims and appeal to clean-eating trends, all while maintaining or even improving texture, yield, and shelf life in their products[26][8].

Clean-Label and Regulatory Advantages

CitruSmart’s profile ticks all the boxes for clean-label and regulatory acceptance, making it easy to introduce in formulations globally:

• Recognizable Labeling: In ingredient declarations, CitruSmart is simply labeled as “citrus fiber.” This common name is easily understood by consumers, contrasting with chemical names or E-numbers. There is no E-number associated with pure citrus fiber, since it is considered a food ingredient (fiber) rather than a food additive emulsifier. For example, in the EU it would not need an E-code, and in the US it appears as citrus fiber or dried citrus pulp[14]. This transparency supports products aiming for a “kitchen pantry” label or a shorter ingredient list.
• GRAS Status: Citrus fiber is generally recognized as safe. In the United States, the FDA has evaluated citrus fiber (from orange, lemon, lime peels) and had “no questions” on its GRAS notice for use as a texturizer and moisture retaining agent in multiple food categories[13]. Approved usage levels are generous (e.g. up to 4% in dairy desserts and 5% in meats per the GRAS notice) which covers typical formulating needs[13]. This means CitruSmart can be readily used in foods without regulatory hurdles, as long as good manufacturing practices are followed. It is also accepted in many other regions given its nature as a fruit-derived fiber – for instance, it can often be used in products aiming for organic certification if the fiber source is from organic citrus (Nexus can likely provide guidance on organic status if needed).
• Allergen-Free & Dietary Friendly: CitruSmart does not come from any major allergenic source – citrus fruits are not among the common allergens (though label declaration of “citrus” may be needed for those rare individuals with citrus sensitivities). The product is naturally gluten-free, soy-free, corn-free, and non-GMO[30]. It contains no added proteins from allergenic sources and no sulfites or other preservative residues. This makes it suitable for a wide range of specialty diets and label claims: vegan, vegetarian, gluten-free, Kosher, Halal, etc. Nexus Ingredient provides CitruSmart with relevant certifications such as Kosher and Halal quality standards[31]. Being plant-based and free of animal derivatives, it meets requirements for vegetarian/vegan product development effortlessly. Importantly, it’s also additive-free (no carriers or chemical additives in the product itself), and has no known toxicity or carcinogenicity, with an excellent safety profile aside from inert dust inhalation considerations[30].
• Sustainable and Upcycled: CitruSmart supports sustainability goals, as it is produced from upcycled citrus peel that would otherwise be waste. By valorizing this byproduct of the juice industry, its production reduces food waste and maximizes agricultural outputs. The manufacturing of CitruSmart involves physical processing of dried citrus peels (washing, drying, milling) without harsh chemicals[8], aligning with principles of green chemistry and sustainable sourcing. Brands using CitruSmart can leverage this story – that their product contains an ingredient made from recycled orange or lemon peels – to enhance their corporate sustainability narratives. The upcycled nature of citrus fiber was highlighted as contributing to cleaner and more sustainable bakery products, for instance[32]. Additionally, because CitruSmart can replace multiple additives with one ingredient, it may simplify supply chains and reduce the carbon footprint associated with producing and transporting numerous separate hydrocolloids.
• No Additive Code (E-number) & Clean-Label Compliance: Many clean-label standards (retailer blacklists, consumer advocacy lists) target artificial-sounding ingredients. CitruSmart helps manufacturers comply with these standards since it is not considered a synthetic additive. Products formulated with citrus fiber can achieve label claims like “No artificial thickeners or stabilizers” or “No chemical emulsifiers” because citrus fiber is perceived as natural and wholesome. It’s essentially dried fruit fiber – an easy concept for regulators and consumers alike. Thus, whether it’s in a “natural” ice cream line or an “organic” soup, CitruSmart fits seamlessly as a label-friendly ingredient that meets regulatory definitions of natural in many jurisdictions (not chemically modified, derived from an edible plant source). Its acceptance by clean-label-conscious retailers has been positive, as citrus fiber has not appeared on “unacceptable ingredient” lists of major food retailers[33].

In summary, CitruSmart offers clear regulatory and consumer acceptance advantages: it is GRAS and globally acceptable, non-GMO, allergen-free, suitable for all major dietary groups, and environmentally friendly. Food manufacturers can confidently innovate with CitruSmart to meet the twin demands of clean labels and high performance. Table 2 summarizes these clean-label credentials:

Table 2: CitruSmart clean-label and regulatory profile.
