Way To Know The whey

We all know the usefulness of curd in food, health, and skincare. Today we will get to know about a liquid that we get when milk curdles. Whey is a natural substance, a light green liquid that precipitates on the top layer of curd, or the liquid that is left over, after cheese making. It will be astonishing to know that this liquid, which is ignored, has numerous health benefits.

Home-made whey contains lactoferrin: A multifunctional protein with iron-binding properties that acts as anti-microbial.

Bovine serum albumin: A substance high in amino acids helps improve antioxidant activity and helps maintain cholesterol levels.

Probiotic organisms: Promote digestion and improves nutrient absorption from food, with all essential amino acids.

Minerals: Rich in zinc and potassium.

Vitamins: Riboflavin

Whey can be used in soups, and even it can be added while making chapatis to the wheat flour.

Processing of whey

Raw milk is collected, cooled at 4 degrees Celsius, refrigerated, and pasteurized. This milk contains 80% casein and 20% whey.

The liquid whey is separated, as a by-product of cheese making using rennet and other enzymes. Whey passes through membrane filtration and ion exchange process, and this results in the production of whey protein concentrate. 

The high protein liquid whey concentrate is spray-dried to obtain the whey protein powder.

Whey powders are preferred by sportspersons, as they help maintain weight and also help build muscle.


Whey protein concentrate and isolate are used in baking mixes, candy, chocolate fudge, coffee whiteners, diet supplements.
