non-fat milk

Non-fat milk, also known as skim milk, is milk from which nearly all fat has been mechanically removed through centrifugal separation, leaving a product containing less than 0.5% milk fat by weight. Derived from bovine dairy cattle, non-fat milk retains the water-soluble components of whole milk—including lactose, proteins (casein and whey), and water-soluble vitamins—while eliminating the lipid fraction responsible for creaminess and the fat-soluble vitamins naturally present in whole milk. The flavor profile is noticeably thinner and more watery than whole or reduced-fat milk, with a slightly sweeter taste due to the relative concentration of lactose. Modern non-fat milk is often fortified with vitamin A and vitamin D to compensate for losses during processing.

Non-fat milk serves as a versatile dairy ingredient in both beverage and cooking applications. It is consumed as a standalone beverage and used in coffee, tea, smoothies, and cereal. In cooking, non-fat milk functions in baked goods, custards, sauces, and soups where its lower fat content and thinner body are either desirable or compensated for through other ingredients. It is particularly valued in health-conscious preparations and in recipes where fat reduction is a dietary priority. However, its reduced fat content diminishes richness in applications traditionally requiring whole milk, such as cream soups or custards, where cooks may need to adjust recipes by adding cornstarch or other thickeners or by using whole milk alternatives.
