All foodstuffs in their natural state will quickly spoil or spoil. In terms of food quality, it can be distinguished into foods that are durable and some that are limited to a certain time.
Based on the ease of damage, food can be classified into 3 groups as follows.
1. Non-perishable foods, which can be stored for a relatively long time at room temperature, such as rice, dried beans.
2. Semi-perishable foods are foods that can be stored for a limited period of time, such as onions and tubers.
3. Perishable foods are foods that spoil quickly when stored without handlings (preservation) such as meat, fish, milk, ripe fruit, and vegetables.
The shelf life of various foodstuffs depends on their water content. The higher the amount of water in the food, the faster the food spoils.
On the other hand, the lower the water content, the longer the shelf life. But if food is stored in a wet or damp state, then the food will quickly change and become damaged.
