When making milk products: comparison of parameters between colloid mill and homogenizer

Homogenization plays a crucial role in dairy production, serving three primary purposes:

1. **Preventing Fat Separation**:

Fat globules in milk naturally rise to the surface, forming a cream layer. While this property is useful for separating milk, it is undesirable in products like sweetened condensed milk, ice cream, and chocolate milk. Homogenization effectively prevents this separation by breaking down fat globules.

2. **Ensuring Product Stability and Homogeneity**:

Homogenization reduces the average size of fat globules to one-tenth of their original size while increasing their number by 10,000 times. This process creates a stable and uniform product texture.

3. **Enhancing Digestibility**:

The small fat globules produced during homogenization are easier to digest. When combined with other nutrients, these globules achieve a digestibility rate of approximately 95%, making the products easier to absorb.

Homogenization is thus essential for improving both the quality and functionality of dairy products.
