  • Lauric Arginate (LAE) is GRAS certified and approved for use in the U.S., Canada, and Mexico, among other countries
  • LAE is a powerful antimicrobial known to reduce various foodborne pathogens and spoilage bacteria
  • Provides the initial kill step in the food production process and packaging equivalent to in situ pasteurization, significantly reducing bacteria loads
  • When combined with other natural preservatives, it can substantially improve food safety and shelf life
  • Does not affect the taste or the sensorial properties of the food
  • CytoGUARD® LA is a highly cost-effective antimicrobial agent
  • Safe to use in food applications

  • L-arginine is an essential amino acid present in many food sources, including poultry, seafood, cheese, cereals, nuts, seeds.
  • Lauric acid can be found in oils such as coconut and palm kernel.
  • Ethanol is the product of the fermentation of sugars. It is short-chain alcohol.

Lauric Arginate is a food-grade antimicrobial synthesized from food components lauric acid, naturally occurring in palm and coconuts, and L-arginine, an essential amino acid. Its remarkable antimicrobial properties, paired with low toxicity levels, make it an optimal bactericidal control tool in food production. This unique antimicrobial agent made from natural ingredients is proven to be extremely effective and can kill up to 99.99% of the foodborne pathogens and spoilage bacteria in a wide range of products.

Protect Your Products From Pathogenic Bacteria

Dealing with food recalls due to contamination results in profit losses and a public relations nightmare for any food brand that can lead to a stock market drop, losing the market share, and permanently damaging the brand in the consumers' eyes.
