The study was carried out to analyze cooking characteristics of important rice varieties grown and processed in Gujarat state of India. In the study cooking characteristics which are of the most important viz. optimum cooking time, elongation ratio, water uptake ratio, gruel solid loss, pasting temperature and final viscosity were determined by standard methodologies and found to be 17 min, 1.523, 2.6, 4.32%, 91.7 °C and 2558 ± 165.6 cP for parboiled rice, 12 min, 1.356, 2.7, 8.25%, 87.9 °C and 3546 ± 142.3 cP for Jeerasar rice and 14 min, 1.318, 2.8, 10%, 93.9 °C and 1523 ± 179.6 cP for GJ-17 rice, respectively. Also, the size i.e. length, width and thickness of all the three varieties were measured and plotted to observe the trend of expansion after cooking. From the above observations, it was found that parboiled rice has comparatively better cooking characteristics but has higher cooking time, which consumers may not accept for household purpose.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
