FOOD TECHNOLOGY

Detailed explanation-1: -Three ways to preserve fresh fruits and vegetables safely are freezing, drying, and canning. Each of these preservation methods will extend the shelf-life of foods for weeks or months while inhibiting the growth of bacteria which can cause food-borne illness.

Detailed explanation-2: -Freeze-dried food can last decades The best thing about freeze-drying is that you can freeze-dry just about anything. You can freeze-dry meats, vegetables, fruits, dairy, ice cream, sauces and entire meals. You name it, you can freeze-dry it (except plain water, obviously).

Detailed explanation-3: -Most shelf-stable foods are safe indefinitely. In fact, canned goods will last for years, as long as the can itself is in good condition (no rust, dents, or swelling). Packaged foods (cereal, pasta, cookies) will be safe past the ‘best by’ date, although they may eventually become stale or develop an off flavor.
