Delta-gluconolactone, or glucono delta-lactone (GDL), is a white crystalline powder with a molecular formula of C₆H₁₀O₆. In water, GDL hydrolyzes to form gluconic acid, which lowers the pH, making it a commonly used acidulant in food. Its acid formation rate is influenced by temperature, concentration, and solution pH. At room temperature, GDL has a low acid release but speeds up significantly with higher temperatures. Soluble at 59 grams per 100 milliliters of water at 20°C, GDL is used for pH control, leavening, and as a curing and pickling agent. It imparts a mildly tart taste compared to other acids, making it favorable for products where a less intense sourness is desired.
The CAS number of delta-Gluconolactone is 90-80-2.

delta-Gluconolactone(GDL) is versatile across various food applications: it acts as a coagulant for silken tofu, an acidifier in dairy products like feta and cottage cheese, and a curing agent for processed meats like sausages, where it lowers pH to inhibit bacterial growth. It’s also used in baking, where it facilitates a gradual carbon dioxide release, enhancing leavening. Beyond food, GDL finds applications in skincare, where it serves as a preservative with low irritant potential and provides UV protection. It even has medical applications, such as in treatments aimed at dissolving kidney stones, demonstrating its utility beyond food processing.

| The effect of δ-gluconolactone, an oxidised analogue of glucose, on the nonenzymatic glycation of human and rat haemoglobin |
This study demonstrates that δ-gluconolactone (δ-GL), an oxidised analogue of glucose, is a potent glycating agent in vitro of haemoglobin present in blood samples from insulin-dependent diabetic and non-diabetic human subjects and from spontaneously diabetic, insulin-dependent BB/Edinburgh (BB/E) rats. , Clinica Chimica Acta Volume 263, Issue 2, 25 July 1997, Pages 239-247 , R.Mark Lindsay a , William Smith a , Wai K.

| Novel Pathway for Alcoholic Fermentation of δ-Gluconolactone in the Yeast Saccharomyces bulderi |
The aim of the present study was to investigate the pathway for δ-gluconolactone fermentation by S. bulderi. To this end, the yeast was grown in glucose- and δ-gluconolactone-limited, anaerobic chemostat cultures. Mass balances were constructed over the cultures to quantify all of the relevant fermentation products. Levels of potential key enzymes in δ-gluconolactone metabolism were assayed in cell extracts of glucose- and δ-gluconolactone-grown cultures. , J Bacteriol. 2002 Feb;184(3):672–678. , Johannes P van Dijken 1, Arjen van Tuijl 1, Marijke A H Luttik 1, Wouter J Middelhoven 2, Jack T Pronk 1,* |
