Since the percent casein is believed to have the greatest influence on the yield of cheese, it is postulated a lower casein content in milk will produce a proportionately smaller amount of cheese for a given volume of milk. Cheese factories presently buy milk on the basis of fat percentage and weight with no regard to the amount of total protein or casein present. Therefore, it would …
