Question

Which of the following is not a vegetable or fruit-based fermented product?
A. Wine
B. Sauerkraut
C. Beer
D. Vinegar

Answer 1

Hint:
Fermentation is a metabolic process where sugar is catalyzed by enzymes that convert the sugar into an acid or alcohol releasing chemical energy in the form of ATP molecules using microorganisms like yeast and bacteria.

Complete answer:
In the process of vegetable fermentation, vegetable sugars are broken down into acid and carbon dioxide, and other aromatic compounds. The carbon dioxide gas produced gives the vegetable tartness and prevents any bacterial growth on them.
Vegetables like cabbage, carrot, radish, and turnip are some vegetables that can be fermented easily at home.
During fruit fermentation, the fruit sugar is broken down by yeast into alcohol. Fresh fruits and canned fruits can be used to make fruit-based wines and other alcoholic drinks.
Wine is a fruit-based fermented product that is made by converting fresh grape juice into an alcoholic beverage.
Sauerkraut is a vegetable-based fermented product that is made using shredded cabbage. It is rich in antioxidants and is very helpful for eye health.
Beer is also made using fruit juice and thus, it is a fruit-based fermented product.
Vinegar is not a fruit-based or a vegetable-based fermented product as it is produced when ethanol is allowed to ferment and turn sour by the action of acetic acid or bacteria.
Thus, the correct answer is:- Vinegar

Option ‘D’ is correct

Note:
Fermentation is a very good way of preserving food. It also enhances and increases the number of beneficial bacteria or probiotics in our gut. Some of the healthiest fermented products are sauerkraut, kimchi, yogurt, etc.
