Physicochemical and cooking properties of rice (Sambha masuri) individually fortified with iron, zinc and calcium

The present study was carried out to investigate the impact of iron, zinc and calcium fortification in rice through parboiling technique on its physicochemical properties. Rough rice were fortified in four different treatments where treatment 1 and 2 involved soaking and steaming at different temperature and duration, whereas, treatment 3 and 4 included germination as a part of fortification in addition to soaking and steaming. The results revealed significant differences in physical and cooking properties of fortified rice among the treatments. The fortified rice took longer cooking time with least cooking time in germinated fortified brown rice in treatment 3 and 4, however, germinated rice had higher gruel solid loss. All the fortified rice had soft gel consistency. A positive and a significant correlation was established between the cooking time and water uptake ratio as well as with the volume expansion ratio and elongation ratio indicating desirable traits of volume changed in cooked rice with increased in lengthwise. It was concluded that iron, zinc and calcium salts did not have impact on physicochemical changes and it was feasible to fortify rice with these micronutrients through parboiling technique. | Physicochemical and cooking properties of rice (Sambha masuri) individually fortified with iron, zinc and calcium
