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.
INTRODUCTION:
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.
