And Glucona-delta-lactone

Glucono delta-lactone (GDL) is a naturally occurring compound that is a solid form of gluconic acid. It is made by drying gluconic acid, which is produced by fermenting glucose, often from corn or other plant sources. GDL slowly breaks down into gluconic acid when exposed to water, creating a mild, gradual acidic effect.

Manufacturers use GDL as an acidulant, a leavening agent, and a curing agent in processed meats. It provides a slow-release acidity that helps to develop color and flavor in cured meats and can also act as a tenderizer. It is commonly found in sausages, cured meats, and some baked goods.

In the United States, glucono delta-lactone is generally recognized as safe (GRAS) by the FDA for use as a food additive. It is metabolized by the body as a carbohydrate. International bodies like JECFA and EFSA have evaluated GDL and have not set a numeric acceptable daily intake, indicating it is considered safe at typical consumption levels. There are no significant health controversies associated with its use.
