Can potassium lactate, be replaced by a clean label natural alternative?

What is potassium lactate?

 

Potassium lactate (C3H5O3K) is the potassium salt of lactic acid, an organic compound naturally present in many foods, particularly in fermented products. Lactic acid is produced by the fermentation of sugars, usually by lactic acid bacteria. The potassium salt is derived by neutralizing lactic acid with potassium hydroxide, resulting in a clear, colorless, odorless, and slightly viscous liquid. Potassium lactate has the E-number E326 and is Generally Recognized As Safe (GRAS) by the US FDA.

Why is potassium lactate widely used as a food additive?

 

Food manufacturers use potassium lactate for several reasons:

  1. Humectant: Potassium lactate acts as a humectant, which helps retain moisture in food products, thus improving their texture and shelf life. This is especially important in baked goods and meat products.
  2. pH regulator: Potassium lactate can be used to control the acidity or alkalinity of food products, which impacts taste, texture, and shelf life. It can also inhibit the growth of spoilage bacteria and some pathogens in food, enhancing food safety.
  3. Flavor enhancer: Potassium lactate can enhance the flavor of certain foods, such as saltiness in meat products, without significantly increasing the sodium content.
  4. Antimicrobial: Potassium lactate can extend the shelf life of various food products by inhibiting the growth of spoilage microorganisms, such as yeasts, molds, and bacteria.
  5. Buffering agent: Potassium lactate can act as a buffering agent, helping to maintain a stable pH in food products, which is crucial for preserving their taste, texture, and appearance.

Potassium lactate is a versatile food additive with several functional properties, including acting as a humectant, pH regulator, flavor enhancer, antimicrobial agent, and buffering agent.

Is potassium lactate really safe?

 

Although it is generally considered safe, there are some concerns regarding its allergenic potential and dietary restrictions for certain individuals.

  1. High potassium levels: For individuals with kidney issues or those on potassium-restricted diets, the consumption of potassium lactate could lead to elevated potassium levels in the blood (hyperkalemia). High potassium levels can cause irregular heartbeats (arrhythmias) and, in severe cases, may lead to cardiac arrest.
  2. Allergic reactions: Although rare, some individuals might have an allergic reaction to potassium lactate, which could manifest as hives, itching, swelling, or difficulty breathing. If any of these symptoms occur after consuming a product containing potassium lactate, it is essential to seek medical attention immediately.
  3. Digestive issues: In some cases, the consumption of potassium lactate might cause gastrointestinal issues, such as diarrhea or abdominal discomfort. These side effects are generally mild and transient.
  4. Public perception: The use of chemical additives in food, even those deemed safe by regulatory bodies, has come under scrutiny in recent years. Some consumers may avoid products containing potassium lactate due to concerns about artificial ingredients or additives.

It is important to note that the negative effects of potassium lactate are generally associated with excessive consumption or specific health conditions. For the majority of the population, consuming potassium lactate within the recommended limits is considered safe.

Is there a natural clean label alternative to potassium lactate?

 

However, there has been a growing demand for clean label products and a preference for natural, minimally processed ingredients. CapBlock® offers similar functionalities without the potential concerns associated with synthetic additives, and will  be more appealing for food manufacturers to meet the demands of health-conscious consumers.

CapBlock®, a cultured brown rice powder, has the potential to replace potassium lactate in various food applications due to its unique combination of properties that address key functionalities provided by potassium lactate. Let’s dive deeper into the scientific reasons behind CapBlock®’s potency as an alternative:

  1. Antimicrobial action: Potassium lactate is used in food formulations for its antimicrobial properties, which help to extend shelf life and improve food safety. CapBlock® is produced through natural fermentation using probiotics, resulting in a product that is highly potent against molds, bacteria, and some yeasts. This broad-spectrum antimicrobial action allows CapBlock® to serve as an effective clean label alternative to potassium lactate for inhibiting microbial growth and spoilage.
  2. Shelf-life extension: Potassium lactate is used to prolong the shelf life of food products by inhibiting microbial growth. CapBlock®’s natural antimicrobial properties also contribute to an extended shelf life, making it a suitable clean label replacement.
  3. Flavor enhancement: Potassium lactate acts as a flavor enhancer in certain foods, such as enhancing saltiness in meat products without significantly increasing sodium content. CapBlock® also functions as a natural flavor enhancer, improving the overall taste and sensory appeal of food products without the need for synthetic additives.
  4. pH regulation and buffering: Potassium lactate serves as a pH regulator and buffering agent in food formulations, helping to maintain stable pH levels and preserve the taste, texture, and appearance of food products. As a natural fermentation product, CapBlock® can also help regulate pH levels and act as a buffering agent, ensuring food quality and stability.
  5. Clean label and consumer appeal: The growing demand for clean label products has led to a need for alternatives to synthetic additives like potassium lactate. CapBlock® is derived from brown rice through a natural fermentation process, making it a clean label ingredient that aligns with consumer preferences for minimally processed, easily recognizable ingredients. This natural origin, combined with its labeling as cultured brown rice or brown rice, makes CapBlock® an attractive choice for food manufacturers seeking to cater to health-conscious consumers.
  6. Prebiotic benefits: An added advantage of CapBlock® is its prebiotic properties, which support gut health and overall well-being by fostering the growth of beneficial gut bacteria. This additional functionality allows food manufacturers to create products that cater to the growing demand for functional foods with health benefits, a feature not provided by potassium lactate.

CapBlock® is a potent alternative to potassium lactate due to its antimicrobial action, shelf-life extension, flavor enhancement, pH regulation, clean label characteristics, and prebiotic properties. These features make CapBlock® a promising clean label ingredient for food manufacturers looking to replace potassium lactate while maintaining product quality and appealing to consumer preferences for minimally processed, health-promoting ingredients.
