K-SORB | Sorbitol/Xylitol Assay Kit
The D-Sorbitol/Xylitol test kit is suitable for the measurement and analysis of D-sorbitol and/or xylitol in food products.
Suitable for manual, auto-analyser and microplate formats.
Colourimetric method for the determination of D-Sorbitol and Xylitol in foodstuffs and wine
(1) D-Sorbitol + NAD+ ↔ D-fructose + NADH + H+
(2) Xylitol + NAD+ ↔ D-xylulose + NADH + H+
(3) INT + NADH + H+ → NAD+ + INT-formazan
Kit size: * 58 assays (manual) / 580 (microplate / 700 (auto-analyser)
* The number of manual tests per kit can be doubled if all volumes are halved.
This can be readily accommodated using the MegaQuantTM Wave
Method: Spectrophotometric at 492 nm
Reaction time: ~ 15 min
Detection limit: 0.20 mg/L
