• sterilization
marketing milk is unnecessary, but powdered milk heating 80℃
• cooling
cooling use freezer or cool water until 40 ml

1. There is nothing new about man’s need to preserve food for storage or convenience of preparation. Sun-drying, salting, pickling and smoking are methods which have been used for centuries and are still being used today. Recent advances in technology have made it possible to preserve food by decreasing the risk of microbiological spoilage with less loss of taste, texture and nutritive value.
