RIDA®CUBE Lactose / D-Galactose is an enzymatic test for the determination of lactose and D-galactose in foodstuffs and other materials, through an UV method.

The test kit is designed for using only with the RIDA®CUBE SCAN instrument (340 nm).

For in vitro use only.

General Information:

Lactose is a disaccharide sugar composed of galactose and glucose. Lactose is an important carbohydrate component of mammalian milk; it is therefore of nutritional importance. The lactose concentration of milk from healthy cows is approx. 4.6 to 5 g /100 g. Lactase (ß-galactosidase), an enzyme found in gastric juice, splits down lactose into D-galactose and D-glucose. People who lack this enzyme after childhood cannot digest milk and are said to be lactose intolerant. Determination of lactose concentrations is particularly important for food products labelled as lactose-free. Moreover, lactose can be used as a sweetening agent in the food industry and should therefore be controlled.

D-galactose occurs very seldom in free form; therefore the measurement over the galactose moiety (lactose / galactose test) is more reliable than over the glucose moiety (lactose / glucose test).
