英文品名:D-Gluconate/D-Glucono-δ-lactone Assay Kit

规格型号:60 assays (manual) / 600 assays (microplate) /600 assays (auto-analyser)

For the specific assay of D-gluconic acid/D-gluconolactone in foods and beverages.


D-Gluconic acid is found in many foodstuffs and beverages, such as

wine, soft drinks, vinegar, meat, fruit juice, dairy products, rice and

honey. This non-volatile organic acid imparts a sour, but refreshing,

taste and, given its occurrence in many natural foods and in human

metabolism, has been granted GRAS status. The ratios of ethanol

and glycerol to D-gluconic acid are a quality indicator in the wine

industry. Botrytis infected grapes exhibit increased levels of this

acid, that can reach 1-2 g/L. There are many other applications of

D-gluconic acid, including dietary supplements, detergents and in

the pickling of foods. D-Glucono-δ-lactone is found in association

with D-gluconic acid, e.g. in wine, and is also widely used in the food

industry. Foodstuffs containing D-glucono-δ-lactone include bean

curd, yogurt, cottage cheese, bread, confectionery and meat.
