Whey Protein Processing Methods

How Whey Protein is Made (part 1)

Ever wonder what all the gibberish means when you read the ingredient details on all types of whey protein supplements? I sure did. Hydrolyzed whey, CFM whey, ion exchange whey... It sure made no sense to me, when I have no clue what these processing methods meant! Well, that was a long time ago, until I decided to figure out what all these meant, and did some digging. ;-)

The Basics

There are two main components of milk protein: 1) casein and 2) whey protein. Most of whey protein come as a byproduct of cheese production. When milk is treated to cause a shift in pH, the casein coagulates and separates, and raw whey is the stuff left uncurded on top of the casein. Its then collected and undergoes various processing steps, and these processing steps are what determines the quality of the whey protein end product.

During the processing, fat and lactose are filtered out to make a lower fat, lower carbs, and higher concentrated protein powder. The protein content can range from 35% to 95% in whey protein. Obviously, the higher the protein concentration, the more processing (filtering) is needed, leading to higher costs as well. Generally, when its greater than 88% protein concentration, its considered WPI (whey protein isolate), and less than that, its considered WPC (whey protein concentrate).

During filtration, low molecular weight compounds like lactose, minerals, vitamins are removed, and the protein becomes concentrated. After filtration, the protein is pasteurized, evaporated, and then dried. The drying is done at low temperatures to avoid denaturing the whey protein.

Pretty simple so far, right? Good!

Microfiltration, Ultrafiltration, and Ion exchange Whey Protein

The two basic methods used to process whey protein are 1) microfiltration and Ultrafiltration and 2) ionexchange.

We'll leave microfiltration and ultrafiltration for later on, lets chat a bit on ionexchange whey protein first.

Ion Exchange Whey Protein

Ionic exchange processing involves separating proteins based on their electrical charge. 2 chemical are used to achieve this: hydrochloric acid and sodium hydroxide. The electrical charge on the proteins attaches them to the resins in the reaction vessel.

Ion exchange processing costs only about 1/5 as much as setting up microfiltration. However, because of the chemical reagents used, pH sensitive fractions are damaged and some amino acids are denatured. Some components that become denatured are:

  • glycomacropeptides (GMPs) - biologically active proteins, positive effect on the digestive system, antiviral activity, improved calcium absorption and enhanced immune function
  • immunoglobulins - antibodies (immune boosting)
  • lactoferrin - lactoferrin makes up about 0.5% - 1% or less of whey protein derived from cows milk (mothers milk will contain up to 15% lactoferrin). (has anti-viral, anti-microbial, anti-cancer and immune modulating/enhancing effects)
  • some alpha lactalbumin - contains a large amount of essential and conditionally essential amino acids

As you can see, alot of good stuff is lost with the ion exchange process. This loss in various components results in higher concentration of other fractions such as beta-lactoglobulin, which is quite stable.

One benefit of ion exchange processing is that the end product has less fat and lactose compared to ultrafiltered proteins, and this is a heavily marketed ploy to get consumers like you and I to buy these, despite the disadvantages of this process as stated above. Well, at least now you know! ;-)

My Top Choices

So which whey protein supplements do I think are the best, and get the most bang for my buck? There are 3 choices:

  1. Optimum Nutrition 100% Whey Protein
  2. EAS MyoPro Whey Protein
  3. AST VP2 Whey Isolate

Take a look at our extensive protein comparison guide, comparing 25 protein powders. You'll see why these are my top choices. However, I were asked to just pick one, I'd go with optimum's 100% whey. Its something I always get, and stick with. Its made up of ultrafilter whey, CFM whey, ion exchange whey, and also some hydrolyzed whey. For the taste and protein quality this product gives, you can make your money last alot longer.

As for VP2, is a little too rich for my blood. ;-) I would consider it one of the top whey protein isolate supplements out there, but it also costs quit a bit more. For roughly the same cost, you get 2lbs of VP2 compared to 5lbs of 100% whey. I guess it's that decision between price and quality. For me, the extra protein quality doesn't justify the dramatic increase in price. Don't get me wrong, I buy VP2 once awhile, just not all the time like I do with 100 whey. ;-)
