Definition and Composition of Milk Derivatives

Milk derivatives refer to substances obtained from milk through various processes, where the original milk components are transformed or isolated to create new ingredients. These derivatives maintain some or all of the nutritional or functional properties of milk but are often concentrated, modified, or purified.

Milk derivatives primarily originate from the three main components of milk:

  • Proteins: Casein and whey proteins separated or processed.
  • Fats: Milk fat or butterfat, sometimes fractionated.
  • Carbohydrates: Mainly lactose, the natural sugar in milk.

Common milk derivatives include:

Milk Derivative Source Component Description Typical Uses
Casein Protein Milk protein precipitated by acid or enzymes Cheese production, food additives
Whey Protein Protein Soluble protein fraction separated from casein Nutritional supplements, beverages
Lactose Carbohydrate Milk sugar extracted through filtration or crystallization Infant formula, pharmaceuticals
Milk Fat / Butterfat Fat Fat fraction separated or concentrated Dairy products, confectionery
Milk Powder Whole Milk Dehydrated milk retaining all components Shelf-stable milk alternative

Methods of Obtaining Milk Derivatives

The production of milk derivatives involves several processing techniques designed to isolate or modify milk components while preserving quality and safety. Key methods include:

  • Separation: Centrifugal separation divides milk into cream (fat) and skim milk (protein and lactose).
  • Ultrafiltration and Microfiltration: Membrane technologies that concentrate proteins or remove lactose.
  • Precipitation: Acid or enzyme treatment to coagulate casein from milk.
  • Spray Drying: Converts liquid milk or derivatives into powder form.
  • Crystallization: Used to isolate lactose in solid form.
  • Homogenization: Reduces fat globule size to stabilize milk fat in milk or derivatives.

Each method impacts the characteristics of the derivative, such as solubility, nutritional profile, and functional properties, making them suitable for specific applications.
