Question

Radha observed that fishes were coated with salt and kept in tray in the fish market. What is the likely use of coating fish with salt? *

1 point

It increases the moisture content of the fish allowing it to survive longer.

It stops the growth of bacteria by reducing the moisture content.

It increases the salt content of the fish that enhances its taste.

It reduces the weight of the fish making the transport easier.

​

Answer 1

Answer:

it stops the growth of bacteria by reducing moisture content

Explanation:

fish are covered with dry salt to check the growth of bacteria.

Answer 2

It stops the growth of bacteria by reducing the moisture content on coating fish with salt.

• Salt is used for preservation of food materials since long time. It functions as preservative by removing the moisture content of food and microbes. Microbes are ultimately killed due to this action.
• The principle behind this is osmosis. High salt hence solute concentration causes water to move out of the cell, thus reducing the water content of cells.
