Whey Protein Isolate (WPI) — Bulk Food Grade
Whey protein isolate (WPI) is whey protein filtered to 90% protein or more on a dry basis, which is the industry definition of an isolate. Most of the fat and lactose is removed. LiquidShop sells it unflavoured and unsweetened as a food-grade bulk powder in 1 kg to 25 kg bags, both for people who make their own protein shakes and for manufacturers of protein powders, bars and beverages.

Isolate vs Concentrate
Concentrate (WPC 80) is about 80% protein, with more lactose and fat and a creamier texture. Isolate contains more protein per gram, mixes thinner and tastes milder. Compare them by cost per gram of protein, not per kilogram. Read the full comparison: whey protein isolate vs concentrate.
