The principal constituents of milk are water, fat, proteins, lactose (milk sugar) and minerals (salts). Milk also contains trace amounts of other substances such as pigments, enzymes, vitamins, phospholipids (substances with fatlike properties), and gases.
Percent concentration by mass is defined as the mass of solute divided by the total mass of the solution and multiplied by 100%. So, c% = msolute msolution ⋅ 100%, where. msolution = msolvent + msolute. There are two ways to change a solution's concentration by mass.
Milk is an emulsion of fat in water. It is also a colloidal suspension of proteins. Other compounds, including lactose and minerals, are. WHY IS MILK WHITE? fully dissolved in the solution. WATER. FAT. PROTEINS. 87.5% 3.9% 3.4% LACTOSE & MINERALS 5.2% FATS IN MILK. Droplets of fat in milk have an average size of 3–4 micrometres.
Milk constituents are synthesized in secretory cells (epithelial cells) from raw materials absorbed from the blood. Milk production requires a lot of nutrients that are brought to the udder by the blood. To produce 1 kg of milk, 400–500 kg of blood must pass through the udder.

The Milk Composition section describes the chemical and physical properties and effects of pasteurization on the compounds in milk. A brief overview of the variation in milk composition is provided below as an introduction to this section.
Lesson-1 Definition of Milk as Per Food Standards and Safety Authority of India, 2006 (formerly Prevention of Food adulteration Act, 1954) and Average Composition of Milk from Cow and Different Species 1.1. INTRODUCTION Milk is a complex fluid containing many components in different states of dispersion.
