The Composition of Milk

 
   

Whole milk is mostly made up of water. Of the rest, there are carbohydrates, fats, protein, and minerals.

Carbohydrates - Milk contains about 5% carbohydrates, mainly in the form of lactose (4.8-5.2%).

Fat - There is 3.5-6.0% lipids (fat) in milk. This figure depends on the breed of cattle and what the cattle is fed.

Protein - There is between 3-3.5% protein found in bovine milk. Of this protein, 80% is casein and 20% is whey protein.

Below, is the breakdown for 100 g of cow's milk, and just for comparison, the composition of 100 g of buffalo milk.

  Nutrient Cow Milk Buffalo Milk
  Water (g) 88.0 84.0
  Energy (kCal) 61.0 97.0
  Carbohydrate (g) 4.7 5.2
  Fat (g) 3.4 6.9
  Protein (g) 3.2 3.4
  Minerals (g) 0.72 0.79
 
   

The Production of Whey

 
   

Whey is a by-product of the cheese of manufacture. It is the liquid part of the milk that is left over from cheese production. This liquid whey can be dried, leaving whey protein powder.

 
   

Dry Whey

 
   

Once dried, whey resembles a white/cream coloured powder. It has a clean, neutral dairy flavour.

Dry whey contains 74% carbohydrate, 13% protein and 1% fat.
