What Is Nisin?
Our Nisin raw material goes through fermentation, extraction, concentration and spray drying processes, standardized with sodium chloride to guarantee stable activity batch by batch. It dissolves well in water and delivers outstanding heat resistance under acidic environments. When used at recommended dosage, Nisin will not alter food color, taste or flavor, perfectly matching global clean label trends.
