| Description | Glucono-1,5-Lactone or GdL is a neutral cyclic ester of gluconic acid, produced with the acid by fermentation of glucose. It is separated from the acid by crystallisation. GdL is a fine, white crystalline powder, freely soluble in water. It is practically odorless and has a slightly sweet taste. Non toxic, it is completely metabolized in the body like a carbohydrate. When added into an aqueous solution, GdL rapidly dissolves, and subsequently slowly hydrolyses to gluconic acid, producing a gentle acidification in the same way as lactic acid-producing bacteria. In solution both gluconic acid and GdL are always in balance. The equivalent point and the rate of transformation are related to concentration, temperature and pH. Applications: Controlled release acidulant Mild acidulant Curing accelerator Leavening agent Chelating agent Preservative agent enhancer Lead: ≤0.001% Heavy Metals (as Pb): ≤0.002% Storage and Stability: Store at RT. Stable for 6 months after receipt. Meets or exceeod USP/FCC specifications Regulatory: Glucono-delta-lactone is supplied in accordance with the latest requirements of the United States Pharmacopeia (USP), the Food Chemicals Codex (FCC) and of Commission Regulation (EU) No 231/2012. In Europe GdL is listed as a generally permitted food additive (E 575) and may be added to all foodstuffs, following the "quantum satis" principle, as long as no special regulation restricts the use. The US Food and Drug Administration (FDA) assigned GdL the “generally recognised as safe” (GRAS) status and permitted its use as a direct human food ingredient without limitation other than current good manufacturing practice (21 CFR Ch. I §184.1318). | ||
