Concept:
Milk powder is an industrial dairy product made by dehydrating liquid milk.
• Types: It can be made from whole milk (WMP) or skim milk (SMP).
• Processing: Usually involves evaporation followed by spray drying.
Step 1: Defining the abbreviation.
SMP stands for Skim Milk Powder.
It is also known internationally as Non-Fat Dry Milk (NFDM).
Step 2: Composition and benefits.
SMP contains less than 1.5% milk fat and approximately 34–37% protein.
Because the fat is removed, it is much more shelf-stable than whole milk powder.
Step 3: Industrial use.
It is widely used in the bakery, confectionery, and meat industries.
It is also used to "standardize" milk solids for yoghurt and ice cream production.
