Preservative For Meat Products

Source:Nusun Biotech Time:2017-12-01

Preservative for meat products is a kind of food preservative produced by microbial fermentation to obtain ε-polylysine, and produced through a unique refined, purified, compound process.


Features:

  ■It is a revolutionary food preservative which is compounded by natural food preservatives ε-polylysine and natural ingredients such as nisin and acidity regulator, it can control the influence of chemical preservatives on food flavor effectively.

  ■It can be used for boiled foods, fried foods, snack foods and pot-stewed meat foods, the filling of mooncakes and buns, and all kinds of dishes in order to prolong the shelf life.
For example(boiled vegetables, fried chicken, meat pies, hamburger steaks, dried fishes,duck necks, duck wings, meat products etc.)
  ■White solid powder.
  ■Add according to the total amount of food, the range is generally 0.5~2%.
(the total amount of food:the total weight of the food processing. For example:100g duck meats+200g brine, the total amount of  food is 300g).

Storage:

  Avoid direct sunlight, low temperature and humidity at the seal. Shelf life is 12 months after manufacture.

Packing:

  1kgⅹ10/carton

Notes:
  ■After opening, cold storage, use as soon as possible.
  ■When using, dissolved fully. If there are some precipitation formation, it is no effect on performance and quality.

  ■The usage and save method may be different according to the customer's production formula and the status of the production line. It needs to be verified on the basis of appropriate verification.

General properties of ε-polylysine:

1.High security
  ■It is a native biological preservative.
2.Antibacterial broad spectrum
  ■It can play a good bacteriostatic effect on gram-positive bacterial(Bacillus cereus, etc.), gram-negative bacterial(E. coli, etc), yeast etc., especially for food poisoning microorganism.
  ■It can also play a good bacteriostatic effect on thermoduric bacterial which is represented by Bacillus subtilis.
  ■It also have a good antibacterial effect on Lactic bcid bacteria which have a great influence on food preservation.
