Question

Read the following passages and answer the following questions:
1. Food Poisoning:- Boojho was invited by his friend to a party and he ate a variety of
foodstuff. On reaching home he started vomiting and had to be taken to a hospital. The
doctor said that this condition could be due to food poisoning. Food poisoning could be due
to the consumption of food spoilt by some microorganisms. Microorganisms that grow on
our food sometimes produce toxic substances. These make the food poisonous causing
serious illnes and even death.
Chemical Method :- Salts and edible oils are the common chemicals generally used to check
the growth of microorganisms. Therefore they are called preservatives. We add salt or acid
preservatives to pickles to prevent the attack of microbes, Sodium benzoate and sodium
metabisulphite are common preservatives. These are also used in jams and squashes to
check their spoilage.
Preservation by Common Salt:- Common salt has been used to preserve meat and fish for
ages. Meat and fish are covered with dry salt to check the growth of bacteria. Salting is also
used to preserve amla, raw mangoes, tamarind, etc.
Preservation by Sugar:- Jams, Jellies and squashes are preserved by sugar. Sugar reduces the
moisture content which inhibits the growth of bacteria which spoil food.
Preservation by Oil and Vinegar:- Use of oil and vinegar prevents spoilage of pickles because
bacterta cannot live in such an environment. Vegetables, fruits, fish and meat are often
preserved by this method.
