Lactose is extracted from milk serum and its extraction is done through two distinct methods. Moreover, it is used to enhance the flavour, texture and colour of your tablet and is generally unreactive. Commercial lactose is obtained from the cow's milk as a by-product of the dairy industry. Additionally, lactose is the disaccharide of the simple sugars D-galactose and D-glucose. In simple words, the lactose molecule comprises one molecule of D-galactose chemically linked to one molecule of D-glucose. Lactose exists in two state forms, known as alpha and beta (designated a-lactose and b-lactose).
