Development of Multigrain Grits and Its Quality Evaluation

Abstract

The research work was carried out to develop multigrain grits and evaluate their quality. Raw grains such as wheat, green gram, kidney bean, corn, barley, sorghum, and foxtail millet were analysed for moisture content, length, width, thickness, AMD, GMD, bulk density, true density, and porosity. The raw grains were soaked in a water bath at different temperatures and then dried in a tray dryer. After drying, the raw grains were mixed in different combinations and milled into Dalia mill. The moisture content of the MGG samples varied between 7.433% and 10.513%. The protein content ranged from 10.970% to 18.376%, while the carbohydrate content ranged from 62.303% to 74.606%. The energy content was calculated to be between 351.676 and 365.763 kcal. The functional properties of the MGG samples included water absorption capacity (ranging from 2.150 to 3.923 g/g), oil absorption capacity (ranging from 2.642 to 3.842 Name : Shaswat Tiwari I.D.

The color properties of the different MGG samples were observed with the L* value ranging from 54.65 to 68.36, the a* value ranging from 5.97 to 9.97, and the b* value ranging from 24.82 to 30.45. The cooking time of the various MGG formulations ranged from 19.33 to 29.00 minutes. The rehydration ratio of the MGG samples varied from 3.48 to 5.13. The MGG samples were packed in aluminium packaging and stored at ambient temperature for different storage periods (0 to 60 days) for further studies. After the storage period, the MGG samples were tested for various properties.
