Enzytec™ D-Gluconic Acid is an enzymatic test for the determination of D-Gluconic Acid in foodstuffs and other materials.
For in vitro use only.
General Information:
Gluconic acid occurs naturally in fruit, honey and wine, but also in meat or dairy products. As a food additive (E574), it is an acidity regulator. It is also used in cleaning products where it dissolves mineral deposits. This acid imparts a sour but refreshing taste. For the wine industry, Botrytis infected grapes exhibit increased levels of this acid that can reach 1-2 g/L. 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 (yogurt, cottage cheese, bread, confectionery, meat and sausages) in order to control the acidity.
