Comparisons of Major Biochemical Constituents and Mineral Composition in Six Cultivars of Aromatic Rice in Manipur

Six aromatic rice varieties collected from the valley districts of Manipur were analyzed for their morpophysiochemical and mineral composition of the grains. All aromatic rice varieties had protein contents in the range of 4.25 to 7.54%, soluble sugar from 7.5 to 10.27 mg/g and total phenolics in the range of 0.52 to 3.90 mg/g with the highest phenol content recorded in Ching Chakhao (3.9 mg/g). Starch was uniformly distributed to all the aromatic varieties ranging from 34.23 to 37.79%. Higher content of K (680.37), Ca (70.17), Mg (34.43), Mn (1.73) and Zn (4.37) was recorded in Chakhao while higher content in Cu and Fe was equally shared by Ching Chakhao and Chakhao Anganba. Among the varieties, Lamsang Chakhao recorded minimum amounts of K (408) while, Chakhao Amubi recorded least amounts in Ca (11.30), Mg (32.63) and Cu (0.57), Phumlou Chakhao in Mn (0.87) and Zn (0.57 mg/100 g). Trace amounts of Co were detected in all the aromatic varieties with the highest being observed in Lamsang Chakhao (0.43 mg/100 g).
