Skim Milk Powder (SMP) is a dairy product made by evaporating pasteurized skimmed cow’s milk. It contains lactose, milk proteins, and minerals in the same relative proportions as the fresh milk from which it was made. Here are some key points about SMP:
1.Composition: SMP typically contains 34-37% protein and is the most common dairy ingredient used for therapeutic and supplementary foods . It is obtained by partially removing fat and water from pasteurized milk .
2. Solubility Classification: SMP is classified based on the heat treatment used during manufacturing:
– High-heat: Least soluble
– Medium-heat
– Low-heat: Most soluble
3. Forms Available:
– Spray-dried SMP: Available in two forms:
– Ordinary or non-agglomerated (non-instant): Requires more time to dissolve.
– Agglomerated (instant): Dissolves quickly.
SMP is widely used in various food applications, including ready-to-use foods (RUFs) and fortified blended foods (FBFs) due to its protein content .
