II. Secrets for optimal preservation of fresh food

A. The refrigerator: an essential ally

1. Setting the ideal temperature

To properly set your refrigerator, note that the coldest zone is the top one. In fact, the cold is falling, so the lower part is less cold. The temperature is therefore adjusted according to this detail.

2. Organize your refrigerator

Organizing your refrigerator is not a detail. The least perishable foods should be at the bottom and the most perishable at the top. Also be sure to separate raw foods from cooked foods.

B. The importance of packaging

1. The different types of packaging

In terms of packaging, we have airtight boxes, storage bags, cling film and even aluminum foil. Each type has its specificity and must be chosen according to the type of food to be preserved.

2. Choice of packaging depending on the food

To properly preserve your food, you must adapt the type of packaging to the food. For example, meats should be vacuum-packed, while vegetables can be stored in airtight containers.

Salting is a traditional method based on the preservative role of salt. Salt helps remove water from food, which inhibits the growth of bacteria responsible for decomposition.

B. Conservation by drying

The principle of drying is to remove all the water present in the food to prevent the development of micro-organisms. It is a very old method that allows food to be preserved for a long time.

C. Conservation by fermentation

Then we have fermentation, a natural method that not only preserves food but also improves its nutritional qualities and taste.

D. Conservation by smoking

Smoking is a preservation method that involves exposing food to smoke produced by the combustion of non-resinous organic materials.

IV. The use of modern technologies for food preservation
