Food preservation includes refrigerating, browning of vegetables, and preventing the growth of bacteria, fungi, or other microorganisms.
What is Food Preservation?
- Although some methods work by adding beneficial bacteria or fungi to the food, food preservation entails stopping the growth of bacteria, fungi, or other microorganisms as well as reducing the oxidation of lipids that lead to rancidity.
- Processes that prevent the aesthetic deterioration of food, such as the enzymatic browning reaction that occurs when apples are chopped during food preparation, may also be included in food preservation.
- Numerous techniques for food preservation will be used in many different food preservation processes.
- For example, to preserve fruit by making jam, it must be boiled (to lower the fruit's moisture content and kill bacteria, etc.), sugared (to stop their regrowth), and then sealed in an airtight jar (to prevent recontamination).

- Apples in a happy meal don't turn brown for days because lemon juice or any acidic source is added to them.
- The acidic source prevents the oxidation of apples and hence, prevents browning.
