Emulsification
Emulsification is a common food processing technique that combines liquids that normally don't mix, like oil and water, to create stable food products. Think of salad dressings, mayonnaise, or milk - these are all examples of emulsified foods. Food processing professionals use this method to improve food texture, appearance, and shelf life. The process involves using special equipment (like homogenizers) and ingredients (called emulsifiers) to create smooth, consistent products that stay mixed together instead of separating.
