The primary carbohydrate found in mammal’s milk, lactose is often referred to as milk sugar. It is the first and only carbohydrate every newborn mammal consumes in significant amounts. Lactose is isolated from dairy products such as whey and whey permeate, which is available after the production of cheese and/or caseinates. 

Lactose (Milk Sugar) is a white to creamy white crystalline product, possessing a mildly sweet taste. It may be anhydrous, contain one molecule of water of hydration, or be a mixture of both forms. It is manufactured from whey or permeate by evaporating, crystallizing, refining and then drying the lactose crystals. 

Lactose for human consumption complies with all provisions of the U.S. Federal Food, Drug, and Cosmetic Act.

This product and its derivatives are capable of sweetening foods, influencing crystallization, adding viscosity, contributing to nutrition and enhancing flavors. Lactose itself has no aftertaste and has a clean mouthfeel. 

There are many diverse food applications for lactose because of its relative sweetness, browning ability, protein stabilizing qualities, alteration of crystallization, flavor enhancement, selective fermentation and nutritive qualities.
