fat-free milk

Fat-free milk, also known as skim milk, is milk from which all or nearly all fat has been removed through centrifugal separation, resulting in a product containing less than 0.5% milk fat by weight. Derived from bovine dairy cattle, fat-free milk retains the protein, lactose, and water-soluble vitamins and minerals of whole milk, including calcium, phosphorus, potassium, and B vitamins, though vitamin A and D are often added to compensate for their reduced levels in the fat-separated product. The milk appears noticeably less opaque and less creamy than whole or reduced-fat varieties, with a thinner mouthfeel and more pronounced dairy tang.

Fat-free milk is primarily used as a beverage and in recipes where minimal fat content is desired, including baked goods, custards, sauces, and coffee beverages. It serves as a direct substitute in most cooking applications calling for milk, though the lack of fat can result in slightly less rich or creamy textures in certain preparations. In professional kitchens and home cooking, it is commonly employed in dough fermentation, cream soups (often combined with roux or other thickeners), puddings, and dietary-conscious preparations. It pairs well with baking applications where water content matters more than fat content.
