Leucidal SF Max Powder

Leucidal® SF Max is a high-specification antimicrobial produced through the fermentation of Lactobacillus in a defined medium. It is an “optimized iteration” featuring a tightened concentration of bacteriocins—the antimicrobial peptides that drive its efficacy. The manufacturing process uses papaya-derived lysozyme to facilitate controlled cell lysis, ensuring the maximum release of these bioactive peptides for superior performance.
