Why should curd and sour substances not be kept in brass and copper vessels?
Curd and sour substances should not be kept in brass and copper vessels because these metals can react with acidic foods, leading to potential health hazards. The main concern is the leaching of toxic metals into the food or liquid being stored, which can contaminate the food and make it unsafe for consumption. Here are the reasons why: Acidic Reactions: Curd and sour substances contain acids (such as lactic acid in curd) that can react with the copper and zinc present in brass or copper vessels. This reaction can cause the release of these metals into the food, leading to metal poisoning. Copper Toxicity: Copper is an essential mineral needed by the body in small amounts, but excessive intake of […] READ MORE...
