1. Why do fruits go bad?

The main reason for fruit spoilage is microorganisms and bacteria. There are a large number of microorganisms and bacteria in the normal environment. After the fruit is harvested, it is easy to be contaminated by these microorganisms during transportation and sale. When the external environment reaches a certain temperature, these microorganisms will multiply in large numbers, causing the fruit to rot and deteriorate.

2. Enzymes are an important cause of food spoilage

Enzymes are also an important reason for food spoilage. Most of the food people eat usually contains a variety of enzymes. When the food is preserved, this substance will react with the nutrients and carbohydrates in the food, causing them to be broken down and produce some low-level harmful substances. Things like fruit rotting and food going bad are all the result of the action of enzymes.

3. Chemical reactions are also an important cause of food spoilage

Some chemical reactions are also important reasons for food spoilage. For example, some foods containing oil will oxidize under certain conditions to produce some chemical components. The oxidized oil will emit a strange odor, causing the food to spoil and also causing some meat products to change color.
