How is recombined milk made?
Recombined milk is liquid milk made by mixing water with skim milk powder and adding milk fat separately until the fat level is right. Reconstituted milk is made by adding water to skim or whole milk powder. The Tetra Pak Dairy Processing Handbook gives pasteurizing at 72 C or more for 15 seconds as the minimum heat treatment.

What is reconstituted milk?
The Tetra Pak Dairy Processing Handbook defines reconstituted milk as liquid milk made by adding water to skim milk powder, whole milk powder or a mix of the two, to standardize the fat content.
What is recombined milk?
Recombined milk is liquid milk made by adding water to skim milk powder and adding milk fat separately, in an amount that reaches the fat level wanted. The fat is usually anhydrous milk fat, which is about 99.8 percent milk fat.
How is recombined milk made, step by step?
- Heat drinking-quality water to about 48 to 53 C.
- Dissolve the powder. The mix should not go above 65 C, which would denature whey proteins.
- Let it stand for at least 20 minutes so the powder hydrates. Too little time can leave a chalky defect or sediment.
- Melt the milk fat and mix it in with a high-shear mixer.
- Pasteurize at 72 C or higher for at least 15 seconds and cool below 4 C. Long-life versions are usually UHT treated at about 138 to 140 C for 4 seconds.
Why do countries use it?
Milk is perishable, and powder can be stored for months or even years. Where fresh milk is scarce, recombining gives a product close to fresh milk. FAO notes that recombined milk from skimmed milk powder and anhydrous milk fat has grown in Southeast Asia, India and Latin America, but that its taste quality is often rated lower than fresh milk.
Is it fresh milk?
No, it is rebuilt from powder, water and fat. We found no official source that compares its nutrition with fresh milk, so we make no claim on that. Check the label to see which kind you are buying.
How do you reconstitute milk powder?
Add water to the powder. The Tetra Pak Dairy Processing Handbook says warm water (40 to 60 C) dissolves powder more readily than cold, and recommends mixing at about 55 C. Mixing below 10 C is not recommended, because it can cause incomplete dissolution and sedimentation. Low-heat powder dissolves more easily than high-heat powder.
How long can reconstituted milk stand?
The handbook says mixes held at warm mixing temperatures should not exceed about three hours, because of bacterial growth risk. This is industrial guidance for dairy plants, not a home storage rule. For home use, follow the instructions on your powder pack.
Why is milk reconstituted at all?
The handbook says milk is perishable and scarce in countries with little dairy production, and that powder can be stored for months or even years without spoiling. Recombination supplies dairy products in regions where raw milk is not available.
Is reconstituted milk the same as recombined milk?
Not exactly. By the handbook’s definitions, reconstituted milk is made by adding water to skim milk powder, whole milk powder or a mix of the two. Recombined milk uses skim milk powder with milk fat added separately. People searching for reconstructed milk usually mean one of these two.
People also ask
What is reconstituted milk?
Liquid milk made by adding water to skim milk powder, whole milk powder or a mix of both to standardize fat content (Tetra Pak Dairy Processing Handbook).
What is the difference between recombined and reconstituted milk?
In the Tetra Pak handbook, reconstituted milk is powder plus water, while recombined milk is skim milk powder plus water with milk fat added separately.
Is reconstituted skimmed milk pasteurized?
In the production method described by Tetra Pak, the mix is pasteurized at 72 C or higher for at least 15 seconds, or UHT treated. Check the pack for the treatment used.
What water temperature is best to reconstitute milk powder?
The Tetra Pak Dairy Processing Handbook describes warm water (40 to 60 C) as better than cold and recommends about 55 C. Above 65 C whey proteins denature.
How is reconstituted milk different from recombined milk?
Reconstituted milk is made by adding water to skim or whole milk powder; recombined milk is skim milk powder and water with milk fat added separately (Tetra Pak handbook).
