drying process
Quick Summary
Dehydration is a food processing technique used to preserve food by removing its moisture, which inhibits the growth of microorganisms and enzymatic activity. This method has been practiced since prehistoric times, with early examples including sun-drying seeds, meat, and fish.12
Modern dehydration techniques, significantly advanced during World War II, allow for the preservation of a wide variety of foods like fruits, vegetables, and meats. Dehydrated foods have a significantly reduced bulk, making them easier to transport and store. Various drying methods exist, including air drying, vacuum drying, and freeze-drying, with the choice depending on the food product. While dehydration concentrates nutrients, some vitamins can be lost during the process, and it's crucial to control bacterial contaminants to prevent food poisoning upon rehydration.12

meat processingDryingDrying is another common method of meat preservation. Drying removes moisture from meat products so that microorganisms cannot grow. Dry sausages, freeze-dried meats, and jerky products are all examples of dried meats capable of being stored at room temperature without rapid spoilage.

Proper drying is therefore ensured by adjusting air circulation, temperature, and humidity. Drying procedures differ for long and short macaroni. In the continuous process, after a first hour in which a crust is formed to protect against mold infection, slow drying is practiced.
