Question

why foodstuff like chutney should,pickles and curd not be stored in containers made of metals

Answer 1

Answer:

Because they will react with the metal

Answer 2

Answer:

Acidic foods include orange juice, pickles, chutney, and curd. Iron and aluminum are both extremely reactive metals. If any of these items are stored in iron or aluminums containers, the acid within them will react with the iron or aluminum to produce toxins.

Explanation:

This is due to the presence of acids in these foods, which react with these metals to produce toxic and poisonous compounds. Acidic foods include orange juice, pickles, chutney, and curd. Iron and aluminum are both extremely reactive metals. If any of these items are stored in iron or aluminum containers, the acid in the food will react with the iron or aluminum to produce toxins.  When foods containing acids are stored in iron or aluminum vessels, the acids present react with the metals in the contents, producing toxic salts and harmful substances that can harm your health. All of the foods discussed here are kept in sterilized vacuum-sealed glass jars. When most metals react with acids, they form salt and hydrogen gas. We cannot store foods such as orange juice, pickles, chutney, and curd. Curds, orange juice, pickles, and chutneys are all high in acid (vinegar and citrus). These foods will react with metal, resulting in poisonous metallic flavors and compounds.

As a result, foods such as orange juice, pickles, chutney, and curd cannot be stored in iron or aluminum containers.
