Match the following:

$\begin{array}{cc}& \\ \text{Food items}& \text{Method of preservation}\\ \text{A. Meat and Fish}& \text{i. Vacuum packing}\\ \text{B. Almonds and cashews}& \text{ii. Pasteurisation}\\ \text{C.Milk}& \text{iii. Salting}\end{array}$

• A. A→ ii; B → i; C→ iii;
• B. A→ ii; B → iii; C→ i;
• C. A→iii ; B → i; C→ ii;
• D. A→ i; B → iii; C→ ii;

Answer 1

The correct option is C A→iii ; B → i; C→ ii;

Food preservation is the process to slow down the food spoilage and thus prolong the shelf life of food. Some of the common food preservation methods are :-

• Salting:- Salting is done by using common salt. Sodium chloride used as common salt absorbs moisture from food, making it dry and uninhabitable for microbes.
• Pasteurisation :- During pasteurisation, milk is first heated to about 70 degrees Celsius for 15 to 30 seconds and then suddenly chilled. Sudden chilling of milk is done to prevent the growth of microbes.
• Vacuum packing :-The food contents are sealed in an airtight container to prevent the growth of microbes.
