Your whey looks great; you say it is cold processed - does that mean it's unpasteurized?
Our cold-processed microfiltration is a technical term to describe the liquid whey being filtered through mesh filters to help concentrate the whey particles. This is a cold process filtration because this is all completed with pressure of flow rather than any heat. As to pasteurization, there are false claims by other companies about raw whey or whey that has not been heated. FDA guidelines actually mandate that the milk that all whey is made from be pasteurized per FDA pasteurization guidelines prior to it being made into whey. Hope this helps!
