Conversion Of Ragi Husk (Polysaccharides) To Reducing Sugars By Acid Hydrolysis And Its Estimation By Different Standard Volumetric Methods

Ragi husk is a lignocellulosic source that can be converted to reducing sugars. It was hydrolyzed using sulphuric acid (2M) and hydrochloric acid (2M) at a constant temperature of 65-70 °C by varying time and concentration. It was found that the degradation has significant effects with respect to amount of polysaccharide present and in turn the sugar yield is around 45-50% each which is estimated by Bertrand’s, Benedict’s and Fehling’s methods respectively.
