Nisin Powder
Practical Implications for Food Applications
Formulation Considerations:
When using nisin in food products, the pH of the matrix affects both its efficacy and shelf life. For example:
In acidic foods (e.g., yogurt, pickles, fruit juices), nisin remains stable and effective throughout storage.
In neutral or slightly alkaline foods (e.g., some cheeses, processed meats), nisin may degrade faster, so manufacturers must balance pH control with other preservation methods (e.g., refrigeration, reduced water activity) to maintain its activity.
Storage of Nisin - Containing Products:
Foods preserved with nisin should be stored within pH ranges that maximize its stability. If the product’s pH shifts during storage (e.g., due to microbial metabolism), nisin’s efficacy may be compromised.
