What is recombined or reconstituted milk?

Quick answer

Under the Codex Alimentarius dairy terms standard, reconstituted milk is made by adding water to dried or concentrated milk, and recombined milk is made by combining milkfat and milk-solids-non-fat in their preserved forms, with or without water. We found no official source we could open that details one standard processing or packaging method.

What is reconstituted milk?

Codex Standard 206-1999 (General Standard for the Use of Dairy Terms) defines a reconstituted milk product as one made by adding water to the dried or concentrated form of the product, in the amount needed to re-establish the appropriate water to solids ratio. Reconstituted milk powder or reconstituted skimmed milk follows this idea: powder plus water.

What is recombined milk?

The same standard defines a recombined milk product as one made by combining milkfat and milk-solids-non-fat in their preserved forms, with or without added water, to reach the appropriate composition of the milk product.

Term Codex definition in short
Reconstituted Water added back to a dried or concentrated product
Recombined Milkfat and milk solids combined, with or without water

Can it be sold under the normal milk name?

Codex says milk and milk products may use the name given in the relevant Codex product standard when made from recombined or reconstituted milk, as long as the consumer would not be misled or confused. Local laws can differ, so check the label.

Is reconstituted milk pasteurized, and how is it packaged?

The Codex definitions do not describe heat treatment or packaging, and we found no official source we could open that gives one standard process. Whether a given product is pasteurized or UHT-treated is stated by its maker and local rules, so read the pack.
