Validation of Methods
Certification

AACC Method 32-32.01

Certification

AOAC Method 999.03

Certification

CODEX Method Type III 

UV-method for the determination of Fructan in foodstuffs,
beverages and other materials

Principle:
                (sucrase, pH 6.5, 40°C)
(1) Sucrose + H2O → D-glucose + D-fructose

                      (Maltase, pH 6.5, 40°C)
(2) maltose + maltotriose → D-glucose

                       (hexokinase + phosphoglucose isomerase)
(3) D-Glucose + D-fructose + ATP → G-6-P + ADP

        (glucose-6-phosphate dehydrogenase)
(4) G-6-P + NADP+ → gluconate-6-phosphate + NADPH + H+

     (exo-inulinase + endo-inulinase, pH 4.5, 40°C)
(5) Fructan + H2O                D-glucose + D-fructose

Kit size:                              50 assays
Method:                              Spectrophotometric at 340 nm
Total assay time:               ~ 30 min
Detection limit:                  1-100% of sample weight
