Clinitest: A simple technique for estimation of reducing sugar content of potatoes

The Clinitest method, originally devised to test urine of diabetic patients, proved to be effective for estimating reducing sugar content of tuber juice. Data obtained by the Clinitest method correlated well with data obtained from the same tubers by the analytical dinitrophenol method and by chip color numbers as determined by Agtron ranges. Simplicity in operation, low cost, and quick results are the main attributes of this method that is potentially useful to the potato industry.
