Directions : In the following questions a statement of assertion (A) ...
Assertion (A): An inoculum of curd is used for curdling of milk.
Reason (R): It contains Lactobacillus, which improves nutritional quality by increasing Vitamin B12.
Explanation:
Introduction:
- Curd is a dairy product that is obtained by coagulating milk. It is commonly used as a food ingredient and has numerous health benefits.
- The process of curdling or coagulating milk involves the conversion of milk proteins into solid curd, which is caused by the action of certain bacteria.
Assertion (A): An inoculum of curd is used for curdling of milk.
- This assertion is true.
- An inoculum refers to a small amount of a substance containing microorganisms that is introduced into a larger volume to initiate a specific biological process.
- In the case of curdling milk, a small amount of curd (which serves as the inoculum) is added to fresh milk to initiate the process of coagulation.
Reason (R): It contains Lactobacillus, which improves nutritional quality by increasing Vitamin B12.
- This reason is also true.
- Lactobacillus is a type of bacteria that is commonly found in curd.
- These bacteria play a crucial role in the fermentation process of milk, where they convert lactose (milk sugar) into lactic acid.
- Apart from aiding in the curdling process, Lactobacillus bacteria also have several health benefits.
- One of the key benefits is the production of Vitamin B12, a water-soluble vitamin that is essential for various bodily functions.
- Vitamin B12 is synthesized by bacteria, including Lactobacillus, and its presence in curd can contribute to the nutritional quality of the final product.
Conclusion:
- Both the assertion and reason are true.
- The reason provides a correct explanation for the assertion.
- Therefore, the correct choice is option A: Both assertion (A) and reason (R) are true, and reason (R) is the correct explanation of assertion (A).
