Key findings
- 1Sweetened condensed milk is roughly 45% sugar by weight; the sugar is both flavoring and preservative
- 2Evaporated milk (unsweetened condensed milk) undergoes the same water-removal process but without added sugar, which makes it less processed
- 3The vacuum evaporation process is a physical method that concentrates nutrients along with sugar; no chemical additives are required in basic formulations
Why is Condensed Milk Level 2 on average?
The production process involves heating milk under reduced pressure to evaporate water, then adding a large quantity of sugar (about 40-45% of the final product). The sugar acts as a preservative, giving condensed milk its extended shelf life without refrigeration. Pasteurization and vacuum evaporation are physical processes; the added sugar is what separates sweetened condensed milk from evaporated milk. Some brands also add disodium phosphate as a stabilizer and carrageenan for texture. In our analysis, condensed milk products average a Processing Score of 2.8, which is Level 2.

How to read a condensed milk label
- 1
Look for just two ingredients: milk and sugar; this is the simplest formulation
- 2
Check for disodium phosphate or carrageenan, which indicate additional processing
- 3
Evaporated milk (no sugar added) is a less processed alternative
- 4
Fat-free versions often add more stabilizers to compensate for removed milkfat

Frequently asked questions
Is condensed milk the same as evaporated milk?
No. Sweetened condensed milk has about 45% added sugar and is thick and syrupy. Evaporated milk has no added sugar and is thinner, just milk with 60% of the water removed. Evaporated milk is the less processed of the two.
Why does condensed milk last so long without refrigeration?
The high sugar concentration (about 45%) acts as a natural preservative by reducing water activity, which prevents bacterial growth. This is the same preservation principle as honey or jam. Once opened, it must be refrigerated.
Can I make condensed milk at home?
Yes. Simmer milk and sugar on the stovetop until reduced by about half. Homemade condensed milk contains just two ingredients and avoids any stabilizers found in some commercial brands.
