The present study was under taken with the view to analyse the physical, nutritional and in-vitro digestibility of raw rice varieties. The results of the study revealed that HB-2 and HKR-48 rice variety had maximum length, breadth, thickness, L/B ratio, seed weight, seed volume, water absorption capacity, bulk density and true density than other varieties and porosity was significantly higher in Permal local variety than other varieties. Moisture, crude protein, crude fat, ash and crude fibre ranged from to , to , to , to and to g/100g, respectively in all the rice varieties. Total soluble sugars, reducing sugars, non-reducing sugars and starch varied from to , to , to and to g/100g, respectively. Rice varieties contained to mg/100g of total calcium, to mg/100g of total iron, to mg/100g of magnesium and to mg/100g of total zinc content. The HCl extractability of calcium, iron, magnesium and zinc were ranged from to , to , to and to per cent, respectively in all the rice varieties. The in vitro protein digestibility and in vitro starch digestibility of rice varied from to per cent and to maltose released/g, respectively. | Physical and nutritional quality evaluation of different rice varieties
