This provides an opportunity to develop and practice colorimetric techniques, and to plot a calibration curve.
words matched: glucose
Risk assessment guidance for carbohydrates including various sugars, cellulose and dextrin.
words matched: glucose
Guidance on how to prepare and use of DNSA (or DNS) reagent for reducing sugars. The reagent may be used qualitatively or quantitatively (colorimetric method).
words matched: glucose
A simple method for identifying reducing sugars using chromatography. The reducing sugars need to be stained with Benedict’s reagent to reveal the spots after the run.
