The effect of polyphenol oxidase on lipolysis and proteolysis of red clover silage with and without a silage inoculant

摘要：

Polyphenol oxidase (PPO) has been shown to reduce both proteolysis and lipolysis in red clover either through deactivation of proteolytic and lipolytic enzymes or/and through the formation of protein‐quinone‐lipid complexes ( Lee et al.,2004).This experiment investigated the time course of both lipolysis and proteolysis in two red clovers with different PPO activities with and without the addition of a silage inoculant (Lactobacillus plantarum).This will help to understand the action of PPO in the silo and hence its potential effects on protein and glycerol based lipid conservation.It will also determine the effect of a more rapid pH reduction with inoculation on PPO activity and final silage quality.
