Source:Nusun Biotech Time:2017-12-01

ε-polylysine 50P is a kind of biological preservatives produced by microbial fermentation to obtain ε-polylysine, and produced through a unique refined, purified, compound process.


Features:

  ■It is a kind of natural nutritional food preservative - poly – lysine, it can control the microbial content effectively and reduce the use of chemical preservatives.
  ■It can be used in food, cosmetics, medical materials, daily chemical products, pet food and other fields.
  ■White solid powder.
  ■This product can be used in combination with other products.

Storage:

  Avoid direct sunlight, low temperature and humidity at the seal. Shelf life is12 months after manufacture.

Packing:

  500gⅹ20/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, 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 nutrive 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
