Partners, long-term cooperation

Unlike broad-spectrum preservatives that may disrupt beneficial microbial communities or alter food flavor, nisin exhibits highly specific antibacterial activity—it primarily targets pathogenic and spoilage gram-positive bacteria (e.g., Listeria monocytogenes, Clostridium botulinum, Staphylococcus aureus) while having little to no effect on gram-negative bacteria, fungi, or viruses. This specificity brings two critical benefits:
Preserves the natural quality of fermented foods: For fermented products (e.g., yogurt, sauerkraut, certain cheeses), nisin inhibits harmful contaminants without killing the beneficial lactic acid bacteria that drive fermentation and contribute to flavor, texture, and nutritional value (e.g., probiotics in yogurt). This ensures the product maintains its characteristic taste and functional benefits (e.g., gut health support from probiotics) while avoiding spoilage or pathogen risks.
Reduces "collateral damage" to food components: Since it does not target non-harmful microbes or react with food nutrients (e.g., proteins, vitamins), nisin avoids altering the nutritional composition or sensory properties (e.g., color, aroma) of food—unlike some synthetic preservatives that may interact with food ingredients and cause off-flavors or nutrient degradation.
