Choosing the Right Milk for Powdering

The foundation of high-quality milk powder lies in selecting the appropriate milk. The choice depends on several factors including the intended use of the powder, fat content, and regional availability. Fresh whole milk is typically preferred for full-cream milk powder, while skimmed milk is used for non-fat varieties. It’s important to ensure that the milk is free from contaminants and has undergone appropriate pasteurization to maintain safety and quality.

Key factors to consider when choosing milk for powdering:

  • Fat Content: Whole milk contains approximately 3.5% fat, which influences the creaminess of the powder. Skimmed milk, with less than 0.5% fat, is used for low-fat powders.
  • Protein Level: Milk protein impacts the solubility and nutritional value of the powder.
  • Freshness: Milk should be processed as soon as possible after collection to minimize bacterial growth.
  • Pasteurization: Heat treatment must be done carefully to preserve nutrients without causing protein denaturation.

Preparation and Standardization of Milk

Before drying, milk must be prepared and standardized to ensure uniform quality and consistency. This involves adjusting the milk’s composition to meet specific product requirements.

Standardization

Standardization adjusts fat and solids-not-fat (SNF) content by adding or removing cream or skim milk. This ensures the final powder has consistent nutritional and physical properties.

Clarification and Filtration

Milk is clarified to remove impurities such as dirt, somatic cells, and bacteria. Filtration systems further improve milk purity.

Pasteurization

Milk is pasteurized using methods such as:

  • Low-Temperature Long Time (LTLT): 63°C for 30 minutes.
  • High-Temperature Short Time (HTST): 72°C for 15 seconds.

This step reduces microbial load while retaining milk quality.

Homogenization

This process breaks down fat globules to prevent cream separation, improving powder solubility and texture.

Drying Techniques Used in Milk Powder Production

The drying method is critical to achieving stable, shelf-stable milk powder with desired physical and nutritional qualities. The two primary drying techniques are spray drying and drum drying.
