UV-method for the determination of Raffinose (also stachyose
and verbascose) and D-Galactose in legume seeds, plant
materials, foodstuffs and feed

Principle:
                                                                  (α-galactosidase)
(1) Raffinose + stachyose + verbascose + H2O → D-galactose +
                                                                                sucrose


               (galactose mutarotase)
(2) α-D-Galactose ↔ β-D-galactose

                     (β-galactose dehydrogenase)
(3) β-D-Galactose + NAD+ → D-galactonic acid + NADH + H+

Kit size:                            * 120 assays

The number of manual tests per kit can be doubled if all volumes are halved. 
This can be readily accommodated using the MegaQuantTM Wave
Spectrophotometer (D-MQWAVE).

Method:                            Spectrophotometric at 340 nm
Reaction time:                  ~ 60 min
Detection limit:                 21 mg/L
Application examples:
Cereal flours, soybean flour, by-products of sucrose manufacture
and other materials
Method recognition:    
Used and accepted in food analysis

Advantages
