Uses of Lactose

Lactose has various uses some of which are:

  • Lactose is used as a nutrient in preparing modified milk and is also added to infants’ food to match the composition of human milk.
  • It helps the body to absorb calcium and a variety of other minerals, like magnesium, copper, and zinc.
  • Because of its physical and functional properties, lactose is added as an ingredient in pharmaceutical products like an excipient and diluent for tablets and capsules.
  • It is used in the food industry as a flavoring agent.
  • It is used in baked goods and also in fermentation for the production of cheese, yogurt, and sour milk.
  • It is also used as a chromatographic adsorbent in analytical chemistry.

Lactose Formula

Lactose is a type of carbohydrate that is also called milk sugar and lactobiose. It is a disaccharide that is synthesized from galactose and glucose subunits. The “lactase” enzyme breaks lactose into glucose and galactose when it is absorbed in the intestine. It is used in the food industry, bacterial identification, and pharmaceutical industry, and is also used as a nutrient, and cutting agent. It is an essential carbohydrate for infants.

What is Lactose Formula?

The molecular formula of lactose is C12H22O11, i.e., it is composed of 12 carbon atoms, 22 hydrogen atoms, and 11 oxygen atoms. It is a white solid that has a mild sweet taste. It is soluble in water and is a non-hygroscopic solid. Lactose was first discovered by Italian physician Fabrizio Bartoletti. Milk contains around 2-8% lactose (by mass). Lactose is found in the mammary glands of all mammals, and a very small amount of lactose can be found in dairy products like yogurt and cheese. It is less sweet when compared to sucrose....
