The Raffinose/Sucrose/D-Glucose test kit is for the measurement and analysis of D-glucose, sucrose and raffinose, stachyose and verbascose in seeds and seed meals. Based on the measurement of D-glucose on enzymic hydrolysis of raffinose, stachyose and verbascose to D-glucose, D-fructose and D-galactose.

Colourimetric method for the determination of Raffinose (also stachyose and verbascose), Sucrose and D-Glucose in legume seeds, plant materials, foodstuffs and feed Principle: (α-galactosidase) (1) Raffinose + stachyose + verbascose + H₂O → D-galactose + sucrose (invertase) (2) Sucrose + H₂O → D-glucose + D-fructose (glucose oxidase) (3) D-Glucose + H₂O + O₂ → D-gluconate + H₂O₂ (peroxidase) (4) 2H₂O2 + p-hydroxybenzoic acid + 4-aminoantipyrine → quinoneimine + 4H₂O

Kit size: 120 assaysMethod: Spectrophotometric at 510 nmReaction time: ~ 20 minDetection limit: 100 mg/LApplication examples: Analysis of grain legumes and other materials containing raffinose,stachyose and verbascoseMethod recognition: Used and accepted in food analysis
