Alpha-D-Lactose monohydrate Chemical Properties,Usage,Production

Chemical Properties

White powder

Chemical Properties

Lactose occurs as white to off-white crystalline particles or powder. It is odorless and slightly sweet-tasting. Spray-dried directcompression grades of lactose are generally composed of 80–90% specially prepared pure a-lactose monohydrate along with 10–20% of amorphous lactose.

Uses

alpha-D-Lactose monohydrate is used as a carrier and stabiliser of aromas, pharmaceutical products, Food industry.

Production Methods

A suspension of a-lactose monohydrate crystals in a lactose solution is atomized and dried in a spray drier. Approximately 10–20% of the total amount of lactose is in solution and the remaining 80–90% is present in the crystalline form. The spray-drying process predominantly produces spherical particles. The compactibility of the material and its flow characteristics are a function of the primary particle size of the lactose monohydrate and the amount of amorphous lactose.

Definition

A sugar that occurs in many plants. It is extracted commercially from sugar cane and sugar beet. Sucrose is a disaccharide formed from a glucose unit and a fructose unit. It is hydrolyzed to a mixture of fructose and glucose by the enzyme invertase. Since this mixture has a different optical rotation (levorotatory) than the original sucrose, the mixture is called invert sugar.

Pharmaceutical Applications

Spray-dried lactose is widely used as a binder, filler-binder, and flow aid in direct compression tableting.

Biochem/physiol Actions

alpha-Lactose is the primary sugar present in milk and the main energy source to a newborn mammalian through its mother′s milk. It is digested by the intestinal lactase (EC 3.2.1.108), an enzyme expressed in newborns. The enzyme′s activity declines following weaning which can lead to lactose intolerance in adult mammals.

Safety

Lactose is widely used in pharmaceutical formulations as a diluent in oral capsule and tablet formulations. It may also be used in intravenous injections.
Adverse reactions to lactose are largely due to lactose intolerance, which occurs in individuals with a deficiency of the enzyme lactase.

storage

Spray-dried lactose should be stored in a well-closed container in a cool, dry place.

Incompatibilities

Lactose is a reducing sugar. The amorphous lactose, which is the most reactive form of lactose present in spray-dried lactose, will interact more readily than conventional crystalline grades. Typical reactions include the Maillard reaction with either primary or secondary amines.
