Question

Lisa was helping her grandmother to arrange her kitchen cabinets. She noticed that her grandmother stored her favourite lemon pickle either in glass or ceramic containers instead of aluminum containers. What can be the reason for that?

Answer 1

Answer:

Among the oldest methods of preservation are drying, refrigeration, and fermentation. Modern methods include canning, pasteurization, freezing, irradiation, and the addition of chemicals. Advances in packaging materials have played an important role in modern food preservation.

Answer 2

beacause, we cannot store lemon pickle in an aluminium utensil because aluminium is a metal and metals readily react with acids to produce hydrogen. When aluminium comes in contact with lemon, which is acidic, would react to give hydrogen and the pickles will be spoiled.
