Lactose makes up around 2–8% of milk (by mass). The name comes from lact (gen. lactis), the Latin word for milk, plus the suffix -ose used to name sugars. The compound is a white, water-soluble, non- hygroscopic solid with a mildly sweet taste. It is used in the food industry.
23 sie 2024 · Foods high in lactose are typically those which contain milk, cheese, butter, or cream. These include infant formula, candies, chocolates, cakes, pies, eggnog, ice-cream, and macaroni and cheese.
The main food products in which lactose can be found are dairy products, milk being their raw material, or recipes in which these products are used. Lactose can also be extracted from milk and employed as an ingredient or additive in a large variety of products.
19 lip 2022 · Lactose is the disaccharide of milk and milk‐containing products. Lactose is hydrolyzed to glucose and galactose by lactase in humans (Reichardt & Berg, 1988; Valle et al., 2019). During the process of digestion, lactose is broken down in the ratio of 47.37% glucose:52.63% galactose.
For management of lactose utilization, understanding lactose production at the cow level, and finding new uses for lactose, it is important to have analytical methods to quantify lactose and a consistent method of expression of the concentration of lactose in milk and milk products.

Lactose, a reducing disaccharide, composed of galactose and glucose linked by a β1 → 4 glycosidic bond (Fig. 1), is the principal carbohydrate in the milk of most mammals; its concentration ranges from 0 to ∼10% (w/w), and milk is the only known significant source of lactose.
