Is skimmed milk bleached

Skimmed milk is not bleached. Skimmed milk is produced by separating the cream from whole milk, resulting in a lower fat content. The milk is then pasteurized to kill any harmful bacteria, but it is not bleached in the process. Bleaching is a separate process used in some food products to remove impurities or improve appearance, but it is not typically used in the production of skimmed milk.
