Product DefinitionNonfat dry milk and skimmed milk powder are very similar but are defined by two different sets of regulations and authorities. NDM is defined by the U.S. Food and Drug Administration, while SMP is defined by CODEX Alimentarius. Both are obtained by removing water from pasteurized skim milk. Both contain 5% or less moisture (by weight) and 1.5% or less milkfat (by weight). The difference is that skimmed milk powder has a minimum milk protein content of 34%, whereas nonfat dry milk has no standardized protein level.
Nonfat dry milk and skimmed milk powder are classified for use as ingredients according to the heat treatment used in their manufacture. There are three main classifications: high-heat, medium-heat and low-heat. Spray-dried nonfat dry milk and skimmed milk powders are available in two forms: ordinary or non-agglomerated (non-instant) and agglomerated (instant).Typical Applications
