Explanation:

Explanation of Food Preservation:

Food preservation is the process of treating and handling food to stop or slow down spoilage (loss of quality, edibility, or nutritional value) caused or accelerated by microorganisms. It helps ensure food safety, extend shelf life, and maintain the food's quality. Freezing is a common method of preserving food without the need for preservatives, where the low temperature inhibits the growth of microorganisms and slows down chemical reactions that cause food spoilage.

Examples of Food Preservation:

Examples of food preservation include freezing fruits and vegetables, canning jams or pickles, drying herbs, and curing meats like bacon. These methods help to retain the taste, texture, and nutrients of the food.

Harmful Effects of Preservatives:

Some harmful effects of preservatives include allergic reactions, digestive issues, and potential long-term health risks. For example, certain preservatives like sulfites can trigger asthma attacks in sensitive individuals. It's essential to be aware of the preservatives used in food and consume them in moderation.
