User's Guide
|
0.5-0.8% ε-polylysine sodium lactate solution,when sprayed on the surface of wet/cold noodles,the microorganisms repro-duction can be effectively inhibited,and the food shelf life can be prolonged.
0.5-0.8% ε-polylysine aqueous solution,when sprayed on the surface of meat products or soak the meat products in the solution for 5 minutes,the microorganisms reproduction can be effectively be inhibited,and the food shelf life can be prolonged.
Polylysine is easily soluble in water and slightly soluble in ethanol.Usually used by dissolvingin 75% alcohol,and sprayed on the food surface or soak the food in the solution. If used together with citric acid,malic acid,glycine and higher fat glycerides,the efficacy an be enhanced.
