nonfat

Nonfat dairy products are milk or cream from which virtually all fat content has been removed through mechanical separation or centrifugation processes, leaving behind water, proteins, lactose, and minerals. The term typically applies to milk, yogurt, and similar dairy products that contain less than 0.5% milk fat by weight according to FDA standards. Nonfat milk, also called skim milk, retains the nutritional profile of whole milk except for fat-soluble vitamins (A, D, E, K) unless fortified. The removal of fat alters the mouthfeel and flavor intensity compared to whole milk, resulting in a thinner body and less creamy texture, though the protein and lactose content remain largely unchanged.

Nonfat dairy products are used as lower-calorie alternatives to full-fat varieties in baking, cooking, and beverages. Nonfat milk serves as a base for sauces, soups, and custards, though it produces thinner results than whole milk and may require thickening agents in applications demanding body and richness. Nonfat yogurt is employed in dressings, marinades, and as a topping; nonfat cottage cheese and cream cheese appear in cheesecakes and spreads. These products are particularly common in contemporary health-conscious cooking and institutional foodservice, though they are less suited to applications where fat contributes essential flavor and texture, such as whipped cream or ice cream.
