• A. A process of freezing food to kill bacteria
• B. The process of heating food to kill harmful bacteria
• C. A method for enhancing the taste of food
• D. A technique for prolonging shelf life

Answer: (B)

Pasteurization is defined as the process of heating food, typically liquids, to a specific temperature for a predetermined amount of time to kill harmful bacteria and pathogens. This method was developed by Louis Pasteur, and it is widely used in the food and beverage industry, particularly for dairy products, juices, and canned foods. The heat treatment involved in pasteurization not only ensures food safety but also helps to maintain the quality and nutritional value of the food products.

The primary purpose of pasteurization is to reduce the risk of foodborne illnesses without significantly altering the taste or nutritional content of the food. This makes it a crucial practice in food safety that helps to protect public health by preventing the growth of harmful microorganisms that could lead to contamination.
