Whey Protein Concentrate Vs Whey Protein Isolate: Explained
When you go to a market there are a few questions that you are asked like, whichprotein powder do you want? There are many types of proteins in the market, andyou must have heard about Whey protein being fast absorbing than the Casein. Evenwhey protein comes in two forms, concentrate and Isolate. Now what are these?
Whey is a water soluble protein in milk and is the bi product that you get when youmake cheese. This is because when we add coagulators in the milk for making curdor cheese, the two types of proteins in the milk Casein and the Whey gets separated.Whey protein being soluble in water remains in the water form and the product(that has coagulated) has Casein. The whey is then separated using differentseparation processes to increase the concentration of Whey protein in the wheywhich still has carbohydrates and fats in it. One of the leading protein powders is:New Zealand protein by Nexpharma.
The two types of Whey protein are:
Whey Protein Concentrate : Whey protein concentrate is obtained through microfiltering process of the whey. This process does not alter the composition of theprotein and hence the protein remains in its natural form. The protein so obtainedhas a concentration of 80% which is better source of protein than any other foodsthat are naturally found. Hence, it is very useful for a body builder.
Whey Protein Isolate : These undergo even rigorous process of filtration called theCross-Flow Micro-filtration. The concentration of protein obtained here is 90% and isfree from fat, cholesterol and lactose that are still there in Whey Concentrates. Sincethey have less fat, it is therefore recommended to people who needs to lower theirbody fat and for athletes. There is a price difference in these two forms of protein,Isolate being the more expensive one because of the extra manufacturing process ithas to go through. It is important to note that the Lactose-intolerants are advisedisolate version. Both are important and the best protein for you can only be decidedfrom your personal health goal.
