2) Prevention of oxidized flavor in milk
1. Several native milk enzymes are implicated in the process of oxidized flavor
① Peroxidase (EC 1.11.1.7)
② Xanthine oxidase (EC 1.2.3.2)
2. Inhibition of milk oxidation
① Bovine trypsin
② Trypsin from cold-adapted fish
3. Concentrations greater than 0.0013% of cold-adapted fish trypsin prevent the oxidation of
lipids in raw milk
3) Preparation of infant milk
1. Lysozyme acts a preservative by reducing bacterial counts in the milk without affecting
Lactobacillus bifius
2. Lysozyme from Artic scallop (Culamys islandica)
- The specific activity of the purified scallop viscera lysozyme is nearly 300% higher than that of
hen egg white lysozyme
