Answer 1

The correct options are

$\bullet$ Preservatives are substances that are generally added to kill or inhibit the growth of microorganisms in a food item.
$\bullet$ Common salt(NaCl) and sugar are natural preservatives, vinegar and sodium benzoate are chemical preservatives.
$\bullet$ Common salt removes the water content in the pickled mangoes. In the absence of water, bacteria can't multiply and hence it acts as a preservative.
$\bullet$ Similarly, fishermen add salt to fish to keep them fresh for a longer period of time.
$\bullet$ Turmeric inhibits the growth of microorganisms and prevents food spoilage.
