What Is Micro-filtering? How Does It Take Place And Why Should I Care?
Whey is the watery part of milk left over once the curd is separated in the process of making cheese.
As a fluid product, whey accounts for 80-90% of the total amount of milk and contains important nutritional components, most notably protein, but also vitamins, minerals, lipids and some lactose. When it’s separated from the curd in connection with cheese production, it contains small cheese “fines” which are strained out in a whey strainer.
The whey is then spun in a centrifuge to remove even more cheese fines and some of the fat. To clean it up even further and make it even more concentrated in protein, it must be filtered with a very fine sieve known as an ultra-filter.
During ultra-filtration, substances with a low molecular weight pass throw the membrane in the filter and a concentrate is obtained. On one side you have a permeate that is free of protein and is used to make lactose (often used in food and pharmaceutical industries), and the other is all protein (your beloved whey protein mostly free of lactose).
Now, in order to make whey into a valuable end product that we all can enjoy, it must be carefully micro-filtered to remove any harmful bacteria. The whey will pass through a special micro-filter whereupon bacteria and spores are separated. A micro-filter with a very, very small pore size of 0.7 microns or less is used which can remove virtually all bacteria and spores. This process also separates any denatured (altered/cooked) whey proteins from undenatured proteins such that the result is a high quality whey protein rich in alpha-lactalbumin and beta-lactoglobulin (two special proteins found in whey that have immunological benefits) and low in fat. Undenatured whey proteins obtained in this manner also have better solubility, which means it dissolves easily in any fluid added to it.
With JayLab Pro Protein, this micro-filtration is also done at a low temperature to prevent any damage to the protein (denaturation) and/or oxidation to any of the fat contained within. The final product is one you can enjoy that’s safe, tasty, easily mixable and healthy for everyone in your family.
