Question

In industry, how to make whey protein isolate and whey protein concentrate protein?

Answer 1

Whey protein isolates and whey protein concentrates are all by-products of cheese. Whey is a
kind of protein present in the milk which is separated using some enzymes. This obtained
liquid whey is further filtered from water, carbohydrates and other fats. Now this liquid consists
three forms of whey and those are : Whey protein concentrate, Whey protein isolate and hydrolysate.
One thing you should should know is that whey protein concentrate particles are bigger in size
compared to whey isolates. To separate whey protein concentrates in industry they use micro
filtration techniques in which they adopt one micrometer sized membranes and allow them to
pass through. While the rest of the smaller size particles i.e) whey protein isolates are separated
using ultrafiltration (0.25 micrometer).
