What the heck is Cross Flow Microfiltered whey protein? I just read that on my container of Whey Protein by BodyTech.
btw,
what is :
-Whey Protein Isolate
-Whey Protein Concentrate
thank you
Concentrate vs. Isolate
A processed whey protein product will generally fall in one of two categories: Whey Protein Concentrate (WPC) or Whey Protein Isolate (WPI). Which one will work better for you? Isolate-hands down. If you are a serious athlete or bodybuilder, a concentrate will not deliver what you need to maintain your competitive edge.
For one thing, WPIs have a higher protein-per-serving ratio than WPCs. For every 100 grams of whey, isolate processing yields over 90 grams of protein, whereas concentrate processing only yields between 34 and 80 grams. In other words, WPIs are over 90 percent ultra-pure protein, with minimal lactose content and virtually no fat! Concentrates, on the other hand, max out at 80 percent protein, and that's with pretty high levels of lactose and fat left over from the original milk product.Even with ultra-filtration processing-used to reduce a concentrate's lactose and fat content-a WPC can't come close to a WPI's pure protein content.
The other difference between WPCs and WPIs is their level of protein "biological activity," as determined by their individual processing techniques. Research has found that only whey proteins in their natural, undenatured state have the ability to perform their characteristic biological functions. And so, much of what makes whey such a phenomenal source of protein, such as immune boosting and anti-cancer properties, is easily forsaken if the product is not processed very delicately. For full biological activity, whey must be processed under low temperature and/or low acid conditions-a common arrangement for WPI processing but less so for concentrates.
