Nisin Powder Price 1kg
Poor stability in certain environments (e.g., neutral pH, high-fat matrices) can be addressed via modification technologies, which improve stability and thus restore or enhance antimicrobial efficacy: Microencapsulation: Encapsulating nisin in materials like chitosan or sodium alginate protects it from hydrolysis, oxidation, and binding to food components. For example, microencapsulated nisin in neutral meat products retains 2–3 times more activity than free nisin, effectively inhibiting Listeria monocytogenes for longer periods. Structural modification: Bioengineering or chemical modification (e.g., acylation) enhances nisin’s stability under neutral/alkaline conditions and reduces binding to proteins/fats, improving bioavailability and efficacy in challenging food matrices.
