Introduction:
Food fermentation is the changes that occur in food due to microbial growth. This process is useful in food processing industry. It is carried out with the help of bacteria or yeasts under anaerobic conditions to cause desired changes in food. Spoilage of food is caused by bacteria which lead to growth of unwanted microorganisms and "undesirable
Answer to Problem 1MC
Correct answer:
Food fermentation helps provide a characteristic “taste to the food”, “lowers the risk of food spoilage”, and “increases food shelf life”. It does not sterilize food.
Therefore, option (c) is correct.
Option (c) is given as “sterilize foods”.
Explanation of Solution
Justify reasons for the correct statement:
Fermentation is caused by microbes such as bacteria and yeasts. It provides characteristic taste to food such as buttermilk and bread. It helps in reducing acidity to avoid food spoilage. Shelf life of food is increased as the process of fermentation by producing compound having antimicrobial activity. Hence, food fermentation does not “sterilize food”.
Hence, option (c) is correct.
Justify reasons for the incorrect statements:
Option (a) is given as “gives foods a characteristic taste”.
Fermentation provides characteristic taste to food such as buttermilk and bread. As the above mentioned statement is a characteristic of fermentation process. Hence, it is a wrong answer.
Option (b) is given as “lower the risk of food spoilage”.
Fermentation helps to avoid food spoilage by reducing acidity. As the above mentioned statement is a characteristic of fermentation process. Hence, it is a wrong answer.
Option (d) is given as “increase the shelf life of the food”.
Shelf life of food is increased as fermentation produces compounds having antimicrobial activity. As the above mentioned statement is a characteristic of fermentation process. Hence, it is a wrong answer.
Hence, options (a), (b), and (d) are incorrect.
Fermentation of food provides a characteristic taste to it, lowers the risk of food spoilage, and increases food shelf life, but does not sterilize food.
