Question

Explain the classification of food according to the length of time of storage.

Hint:

Classifying food helps in proper storage, preventing food wastage, and maintaining food safety for consumption.

Answer 1

Food items are categorized into three groups based on their storage duration:

1. Perishable Foods:

• These foods degrade rapidly if not stored correctly.
• Refrigeration or freezing is necessary to prolong their usability.
• Examples: Dairy products, fresh produce, meat, and fish.
• Storage: Store in refrigerators between 0-5°C.

2. Semi-Perishable Foods:

• These items have a longer shelf life than perishable foods but will eventually spoil within weeks or months.
• They do not require immediate cooling but should be kept in a cool, dry environment.
• Examples: Root vegetables, nuts, grains, and eggs.
• Storage: Store in pantries or well-ventilated spaces.

3. Non-Perishable Foods:

• These foods maintain freshness for extended periods, lasting months or even years.
• Preservation methods like processing, drying, or canning are commonly used.
• Examples: Grains, flour, sugar, salt, and preserved goods.
• Storage: Keep in dry, sealed containers in cool locations.

Summary Table:

\(\text{Type of Food}\)	Examples	Storage Method
Perishable	Milk, vegetables, meat	Refrigeration (0 - 5°C)
Semi - Perishable	Onions, nuts, cereals	Cool, ventilated areas
Non - Perishable	Rice, sugar, canned food	Dry, sealed containers
