"From the preceding discussion it may be concluded
that COPs are formed in most processed products
containing cholesterol. Therefore, it is difficult to
prevent COPs formation in foods unless they are cholesterol-free."

How do you know if the cholesterol in your protein is oxidized? Any pasteurization and drying at high temperatures as well as exposure to oxygen will oxidize a portion of the cholesterol in a product (not to mention denature proteins.) It has also been proposed that cholesterol undergoes auto-oxidation simply under what would be considered simple storage conditions.

"Isolated milk proteins contained a residue of fat, 0.6% for isolated Casein and 5.7% for isolated Lactalbumin, and were exposed to several processes, including spray-drying. So, even if they were nonfat products, they contain significant amounts of COPS."
Sicher vor oxid. Chol. ist man nur, wenn das Produkt kein Chol. enthält.
