The Applied Research Of ε-poly-L-lysine In The Milk Drink
Abstract: This paper outlines the ε-poly-L-lysine in the application of milk drinks. ε-poly-L-lysine is widely antibacterial poor's, it has a good inhibitory effect on gram-negative bacteria, gram-positive bacteria, but its effect on the inhibition of yeast and mold relatively weak. This study will add ε-poly-L-lysine in the milk drink, kept on 37℃±1℃, to discuss the experimental use of orthogonal ε-poly-L-lysine concentration, sterilization temperature, sterilization time on the ε-poly-L-lysine in Milk drink in the inhibitory effect of the impact. Through microbiological analysis detected after adding ε-poly-L-lysine the change in the total number of bacteria in drink milk. The results showed that ε-poly-L-lysine concentration, sterilization temperature and time will affect the sterilization ε-poly-L-lysine in the milk drink in the inhibitory effect, while a greater impact on the ε-poly-L-lysine concentration, followed by the sterilization temperature and the sterilization time. At the same time, we can see that ε-poly-L-lysine thermal stability is very good.
