Nisin 500g/1Kg/25Kg
Narrow Antimicrobial Spectrum:
Ineffective against gram - negative bacteria, yeasts, and molds unless combined with other agents.
pH - Dependent Activity:
Requires acidic conditions for optimal stability, limiting use in neutral or alkaline foods.
Summary of Key Performance Characteristics
Characteristic Description
Antibacterial target Gram - positive bacteria (e.g., Listeria, Clostridium), limited activity against gram - negative microbes.
pH stability Most stable at pH 3–5; rapid degradation at pH > 7.
Thermal stability Heat - resistant in acidic media; less stable at neutral/alkaline pH.
Solubility Poorly soluble in water at neutral pH; improved solubility in acidic solutions.
Safety profile GRAS - listed, natural, non - toxic, and biodegradable.
Synergy Enhances efficacy when combined with other preservatives or processing methods.
Dosage Effective at low concentrations (50–1000 ppm).
These characteristics make nisin a versatile and safe preservative for acidic food systems, particularly in applications where naturalness, targeted antibacterial action, and minimal sensory impact are critical.
