(d) food from puffed or enlarged can should not be consumed. (e) when using frozen food item one should take out only the required quantities thawed food should never be frozen.​

Answer 1

Answer:

A. Yeast is added to dosa's batter so that the process of fermentation can take place. The process of fermentation takes around 8 hours and so it is suggested to keep the batter of dosa for 8 hours before preparing one. Fermented dosa's are good for health as they help is digestion and are good for cholesterol as well.

B .

Brushing Before Sleeping Prevents

Bacteria digest the food remnants on teeth and under the gums. The by-product is acid production which damages tooth enamel and leads to cavities. Saliva helps protect your teeth from damaging acids during the day.

C.

Pickles are kept in households for years and to ensure they do not go bad soon, lots of salt is added to them. Sugar and salt reduce the water content and make it unavailable for the growth of microorganisms. As a result,the foods get preserved.

Food from puffed or enlarged cans should not be consumed because sometimes it is not only the hydrogen gas inside the cans that has resulted in its swelling. They give off carbon dioxide which spoils the food inside the can and also results in its swelling.

E. When using frozen food items one should take out only the required quantities thawed food should never be refrozen, as while putting a thawed piece of steak or brick of cheese back into the freezer might lead to some changes in taste or texture, it's perfectly safe and poses no risks to your health.
