乳糖/蔗糖/D-葡萄糖检测试剂盒

The Lactose/Sucrose/D-Glucose assay kit is suitable for the measurement and analysis of sucrose, lactose and D-glucose in flour mixtures and other materials.

Colourimetric method for the determination of Lactose, Sucrose
and D-Glucose in foodstuffs, beverages and other materials

Principle:
(invertase)
(1) Sucrose + H₂O → D-glucose + D-fructose

(β-galactosidase)
(2) Lactose + H₂O → D-glucose + D-galactose

(glucose oxidase)
(3) D-Glucose + H₂O + O₂ → D-gluconate + H₂O₂

(peroxidase)
(4) 2H₂O₂ + p-hydroxybenzoic acid + 4-aminoantipyrine →
quinoneimine + 4H₂O

Kit size:  100 assays of each
Method:  Spectrophotometric at 510 nm
