Question

why should curd be not kept in copper or brass vessels?what is done to protect it ?

Answer 1

Answer:

The substances having sour taste are most likely acids, because they have acidic nature. For example yogurt and lemon juice have acidic nature and sour taste.

These products are kept in steel or plastic vessels instead of copper or brass vessels. Reason is that they can react with copper and brass and are transformed into toxic substances which can be harmful for human health.

Therefore they are not stored in metal containers.

Answer 2

Answer:

Curd should not be kept in copper or brass vessels because the acid present in curd (lactic acid) reacts with the metal of the vessel ,i.e. copper or brass. ... Also, the reaction between copper/brass with the acid in curd will produce toxic products, which if consumed by us, can cause food poisoning
