Define emulsification in food science.

• A. The process of cooking food in a vacuum-sealed bag
• B. The process of mixing two immiscible liquids into a stable mixture using an emulsifier
• C. The method of exposing food to steam to remove impurities
• D. The technique of frying food to increase its crispness

Answer: (B)

Emulsification in food science refers to the process of mixing two immiscible liquids, such as oil and water, into a stable mixture. This is achieved through the use of an emulsifier, which is a substance that helps to stabilize the mixture by reducing the surface tension between the two liquids. Emulsifiers typically have a hydrophilic (water-attracting) part and a hydrophobic (water-repellent) part, allowing them to interact with both phases. When emulsification occurs, the emulsifier creates a barrier around tiny droplets of one liquid dispersed throughout the other, preventing them from coalescing back into separate layers. Common examples of emulsifiers used in food include egg yolks (which contain lecithin), mustard, and certain proteins. Understanding emulsification is crucial in food preparation because many common food products, such as mayonnaise, salad dressings, and sauces, rely on this process for their texture and stability. Proper emulsification ensures that the final product has a consistent, creamy texture and prevents separation over time.
