Food preservation includes processes that make food more resistant to microorganism growth and slow the oxidation of fats. This slows down the decomposition and rancidification process. Food preservation may also include processes that inhibit visual deterioration, such as the enzymatic browning reaction in apples after they are cut during food ...

Food storage is a way of decreasing the variability of the food supply in the face of natural, inevitable variability. [1] It allows food to be eaten for some time (typically weeks to months) after harvest rather than solely immediately.
Curing is any of various food preservation and flavoring processes of foods such as meat, fish and vegetables, by the addition of salt, with the aim of drawing moisture out of the food by the process of osmosis. Because curing increases the solute concentration in the food and hence decreases its water potential, the food becomes inhospitable ...
The history of early food regulation in the United States started with the 1906 Pure Food and Drug Act, when the United States federal government began to intervene in the food and drug businesses. When that bill proved ineffective, the administration of President Franklin D. Roosevelt revised it into the Federal Food, Drug and Cosmetic Act of 1937. This has set the stage for further ...
Salting is the preservation of food with dry edible salt. [1] It is related to pickling in general and more specifically to brining also known as fermenting (preparing food with brine, that is, salty water) and is one form of curing. It is one of the oldest methods of preserving food, [1] and two historically significant salt-cured foods are ...
The most important role plastic wrap plays in food packaging is protection and preservation. Plastic wrap can prevent food from perishing, extend its shelf-life, and maintain the quality of food. Plastic wrap generally provides protection for food from three aspects: chemical (gases, moisture, and light), biological (microorganisms, insects and animals), and physical (mechanical damage). In ...
Grapes being trodden to extract the juice and made into wine in storage jars. Tomb of Nakht, 18th dynasty, Thebes, Ancient Egypt. Sourdough starter. In food processing, fermentation is the conversion of carbohydrates to alcohol or organic acids using microorganisms — yeasts or bacteria —under anaerobic (oxygen-free) conditions. Fermentation usually implies that the action of microorganisms ...
