PRESERVATION OF FOODS, FOODSTUFFS OR NON-ALCOHOLIC BEVERAGES; CHEMICAL RIPENING OF FRUIT OR VEGETABLES

Introduced: September 1968

Description

A23B encompasses methods and apparatus for extending the shelf life and maintaining the quality of foods, beverages, and foodstuffs through preservation techniques such as freezing, drying, salting, smoking, and chemical treatment. This classification also covers processes for chemically accelerating or controlling the ripening of fruits and vegetables through ethylene application or similar chemical agents. The subclass includes technologies for food packaging designed to preserve contents, antimicrobial treatments, and storage condition control, but excludes fermentation processes (covered under A23C) and thermal processing like canning or sterilization (covered under A23L). Applications range from industrial food processing to household preservation methods.

IPC and CPC are identically structured here. All 15 subcodes exist in both systems.

2 shared codes have differing titles between IPC and CPC.
