UV-method for the determination of Galactomannan in legume
seeds, foodstuffs and plant products

Principle:
                                 (β-mannanase)
(1) Galactomannan + H2O → galactomanno-oligomers

                                  (β-mannanase + α-galactosidase)
(2) Galactomanno-oligomers + H2O → D-galactose +
                                                                     manno-oligomers


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

Kit size:                             100 assays
Method:                            Spectrophotometric at 340 nm
Total assay time:              ~ 90 min
