Hint: Pasteurization is a process through which food substances are heated at less than 100 C and then cooled faster and then packed in containers.
Complete answer: The process of pasteurization was invented by Louis Pasteur in 1864. Actually, this process was initially developed to make wines free from microbes.
Later it was also used to remove microorganisms from milk. This is called pasteurization of milk. Now the process of pasteurization is used to preserve various kinds of food.
This is used for bakery products like bread.
Pasteurization can be done by direct heating or by steam.
The temperature required for this process varies with the type of food substances.
For milk, it is 62 C, for 30 minutes, and for wine, it is 81 – 85 C, for tomato sauce, it is 121 C. Acidic food is boiled at 100 C. Mostly all canned food items are preserved by this method. Sometimes chemicals and antibiotics are also used in this process.
After pasteurization food is packed in air-tight containers and sealed. This process has developed as the best method for preservation.
So the correct answer is A. 1864
Note: During the process of pasteurization temperature and duration are very important. If the temperature is high then the duration of the process will be short.
If the temperature is low then the duration of the process will belong.
