Leucidal® SF Max

Leucidal® SF Max is an optimized fermentation extract. Produced through the fermentation of Lactobacillus in a defined medium, it contains a high concentration of naturally produced bacteriocins. During manufacture, Lysozyme (sourced from papaya) is used to facilitate controlled cell lysis, ensuring the maximum release of antimicrobial peptides into the final water-soluble liquid.
