Study Notes
Particle Size Reduction
- Milling operation produces a predetermined range of particle sizes, crucial for processing properties of some products.
Benefits of Size Reduction
- Size reduction in food processing enhances uniformity, increases surface area, and improves mixing and blending.
Emulsification
- Emulsification is the process of combining two or more liquids that don't normally mix, creating a stable emulsion, which is important in food products like mayonnaise and ice cream.
Homogenization
- The main purpose of homogenization in food processing is to create a uniform mixture of fat molecules in milk and other liquid products, ensuring consistent taste and texture.
Milling to Powders
- Cocoa beans are an example of a food product that benefits from milling to powders, resulting in cocoa powder, a key ingredient in chocolate production.
