What Are the Shelf Life of Common Foods & Canned Foods?

Due to the worldwide lockdown for Coronavirus pandemic, people are stockpiling food items. It is important to store food items with longer shelf lives as they can be consumed at any time during the lockdown.

The food items we purchase from the market or the fruits and vegetables grown in the backyard of our houses all have a shelf life. It is very important to know the shelf life of the food items because they cannot be kept beyond a certain period of time.

It is the length of time during which the food items will remain fresh and are safe to eat. The shelf life of foods starts from the time the food is manufactured.

Food items get spoiled due to moisture, domestic storage, chemical change, food-packaging interaction, and extreme temperature, thus food tends to change in texture, colour and flavour after their shelf life is over. 

Oily and fatty food items have longer shelf lives and are stored at room temperature. They stay longer as they do not contain moisture. As we know the presence of moisture in the food items leads to the growth of microorganisms and tends to spoil the food.

Poultry products do not stay for a longer time and are recommended to consume on the same day. Raw meat contains more moisture and is prone to microbial attack. Shelf life of poultry products in the fridge is for 2 to 5 days.

Grain products such as rice and corn can be stored for a longer time, whereas wheat products like bread do not stay long as they do not contain preservatives.

Dairy products like milk, paneer, cheese, and tofu should be stored in the refrigerator as they have very short shelf lives. It is always recommended to consume milk within 1 day. 

When perishable foods are purchased from the market, they should be stored in a freezer. The temperature of the freezer should be 0°F. Freezing temperature is important to keep foods stay fresh for a longer time.
