Whey Protein Concentrate versus Isolate

by | Jan 4, 2022 | Articles, Conditions, Nutrition

Here are the main steps in making whey protein isolate.

Whole milk -> Cheesemaking -> Cheese and Whey (whey protein, a lot of lactose, a lot of minerals)

Filtration…

Whey protein concentrate (25-80% whey protein, up to 55% lactose, 1-7% fat)

Micro filtration…

Whey protein isolate (>90% whey protein, negligible lactose, <1% fat)

***

Whole milk = 87% water and 13% solids

Milk solids = 27% protein, 37% lactose, 30% fat and 6% ash/minerals

Milk protein = 20% whey and 80% casein
