密三糖或棉子糖/蔗糖/D-半乳糖检测试剂盒 Raffinose/Sucrose/D-Glucose Assay Kit 货号:K-RAFGL Megazyme中文站

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 assays
Method: Spectrophotometric at 510 nm
Reaction time: ~ 20 min
Detection limit: 100 mg/L
Application examples:
Analysis of grain legumes and other materials containing raffinose,
stachyose and verbascose
Method recognition: Used and accepted in food analysis
