Explanation:
Detailed explanation-1: -Spray drying is the most preferred method as it produces even particles than the other methods. The best way to make powdered milk is to use pasteurized milk. Raw milk should not be used and for best results, it is recommended to use skim milk as the less fat there is, the better the milk powdered will store.
