Test Method: Fresh vinegar→add different amounts of ε -polylysine→package→sterilization(85℃,30min)→storage(37℃)→total number of bacteria colonies, inhibition rate.
Result:
When ε-polylysine was used as a preservative in vinegar alone, when the dosage was in the range of 0 ~ 100mg / kg, the inhibitory rate increased with the increase of ε-polylysine dosage.
Polylysine is an ideal natural antimicrobial to prolong the shelflife, with a high natural antimicrobial activity against a wide range of fungi, Gram-positive and Gram-negative bacteria and their spores.
