Nisin China Supplier Price,Preservative Type

TIME:2024-09-11

Nisin, as an effective, non-toxic, safe, and natural food preservative with no side effects, has broad applications in the food industry. It can be used in combination with various other preservatives to enhance antibacterial effects and reduce the amount of single preservatives needed. Below are some types of preservatives that can be synergistically used with nisin and their characteristics:

1. Natamycin

·Characteristics: Natamycin is a polyene macrolide antibiotic obtained through the fermentation of Streptomyces and is highly effective in inhibiting yeast and mold growth.

·Synergistic Effect: Nisin combined with natamycin can inhibit both fungal and bacterial growth, extending the shelf life of food. For example, studies on pickles and chicken show that the combined use of nisin and natamycin provides better antimicrobial effects than using either preservative alone.

2. Chemical Preservatives

·Common Types: Examples include sodium dehydroacetate, sodium propionate, etc.

·Synergistic Effect: Nisin can be combined with these chemical preservatives to reduce the amount of chemical preservatives used and improve food safety. For instance, in steamed cakes, a preservative blend of nisin with sodium dehydroacetate and sodium propionate significantly inhibits spoilage microorganisms and offers better antimicrobial effects than chemical preservatives used alone.

3. Natural Preservatives

·Common Types: Examples include tea polyphenols, chitosan, citric acid, etc.

·Synergistic Effect: Nisin can be used synergistically with these natural preservatives to enhance antimicrobial effects and improve food quality. For example, in chilled meat preservation, a combined solution of nisin, tea polyphenols, and sodium lactate can significantly extend the shelf life of chilled meat.

4. Other Biological Preservatives

·Common Types: Examples include lysozyme, sodium diacetate, etc.

·Synergistic Effect: Nisin can also be used in combination with other biological preservatives to broaden the antimicrobial spectrum and enhance preservation effectiveness. For example, in certain meat processing applications, the combination of nisin and sodium diacetate effectively inhibits the growth of a variety of spoilage microorganisms.

Precautions

When choosing preservatives to use in combination, ensure that all preservatives comply with food safety standards and are used within the prescribed limits.

The synergistic effects between different preservatives can be influenced by various factors such as pH, temperature, and food matrix. Therefore, thorough testing and evaluation should be conducted before use.

The use of preservatives aims to inhibit bacterial growth but cannot completely replace proper food processing and storage conditions. Companies should maintain good processing environments and storage facilities to ensure food safety and quality.

Nisin can be used synergistically with various preservatives to enhance antimicrobial effects and reduce the amount of preservatives used. When choosing and using preservatives, factors such as food type, processing conditions, and safety standards should be comprehensively considered.
