How does food spoil?

Answer 1

1. When air gets at it, it oxidizes and its quality diminishes.
2. Microorganisms from the air land on the food and can begin to grow. this causes an unpleasant smell, bad taste, discoloration and it can become dangerous to eat.
3. Enzymes in the food can continue to act upon the food, leading to over-ripening and ultimately, spoilage.
4. Pests can get into food and spoil it with their wastes.

All of these causes are slowed via refrigeration or freezing and proper dry goods storage.

Answer 2

The HARMFUL MICRO-ORGANISMS (germs) easily go onto the foods unless they are stored properly. Micro-organisms are BACTERIA, VIRUSES AND FUNGI.
