Question

Pasteurization is used to
A. Sterilize milk
B. Kill harmful microbes in milk
C. Cooldown the temperature of the milk
D. Increase the temperature of the milk

Answer 1

Pasteurization is a food handling strategy where a gentle warmth treatment is applied to food to kill harmful microbes. It is a process that makes food items safe to be consumed. This process is named after Louis Pasteur.

Complete step by step answer: Pasteurization is used to kill harmful microbes present in the milk. It is also carried out in packaged food products such as juice, eggs, cheese, margarine, vinegar, sauerkraut, almonds, brew and acidic canned foods. Pasteurization involves applying warmth to a food item. The temperature and time that the food is warmed shifts and relies upon: (1) the kind of food and (2) the microbe being killed. The warmth cycle eliminates unsafe microbes (microorganisms) or that can ruin the food and decreases enzymatic movement that can adjust tangible attributes after some time.
Food can be purified prior to packaging or after packaging. For instance, crude milk or squeeze can move through a warmth exchanger preceding being bundled in compartments, and solid food can be warmed after being set into containers utilizing a group pasteurizer.
So, the correct answer is option B.

Note: All microbes are not harmful, many of them are useful to man in different ways. For example - Lactic acid bacteria (LAB) like Lactobacillus are added to milk which converts lactose sugar of milk into lactic acid which causes coagulation of milk protein casein. Milk is changed into curd, yoghurt and cheese. Curd is more nutritious than milk as it contains several vitamins cyanocobalamin and organic acids. LAB in curd also checks the growth of disease-causing microbes. Starter or inoculums used in the preparation of milk products that contain millions of LAB.
