These constants indicate a direct temperature-dependence of water absorption in paddy. Integrated crop management practices can improve rice (Oryza sativa L.) grain yield, but the effects of such practices on dry matter accumulation and photosynthetic productivity are inconsistent and not well understood. gelatinization temperature were also influenced by varieties and ageing conditions. The decline in percentage genetic integrity during the artificial ageing indicated a systematic ageing-induced genetic alteration. This study also investigated how microwaves can promote rice aging. Thai brown rice (BR), parboiled brown rice (PB) and parboiled paddy (PP) with Chainat1 variety were stored in polyethylene bag at different temperatures of 4°C, 25°C and 37°C for six months. This review may contribute to better understanding of the impacts of postharvest processes on rice grain quality, and provide insights into potential improvements in these practices for rice production and utilization in the whole rice industry. Khazar and Neda had highest germination percentages when exposed to 120 hr seed ageing. Rice ageing is a complicated process, which involves changes in physical and chemical properties of the rice grain. Besides that, Saikrishna et al. Although during the last decade an important but limited progress (mainly construction of protein datafiles) has been made in the field of rice proteomics, it is only recently that dedicated research groups have taken this challenge to systematically analyze the rice proteome at the cell (and organelle), tissue, and whole plant level. The high protein content is particularly good for small children in terms of nutrition. A rice grain cultivar called ‘Khoa Dawk Mali 105’ was aged for three different time periods, ranging from 0 to 12 months. The addition of isolated oryzenin to isolated rice starch resulted in pasting behaviour which more closely approximated that of an extensively aged flour. Increases in effective panicle number and spikelet number per panicle were the main reason for the increase in yield under the integrated crop management treatments. The physicochemical properties like amylose content, liquification number decreased while the free fatty acid content increased with aging. However, little is known about the mechanism of the accelerated aging seeds in hybrid rice photoperiod-thermo-sensitive genic male sterile (PTGMS) lines. With its distinguished author Rice quality: a guide to rice properties and analysis proves an invaluable resource for professionals in the rice industry and researchers and post-graduate students interested in rice. Swelling and water absorption of rice grains increased during storage. The results of electrophoresis showed that oxidation of proteins in the former was advanced to the same degree as in the latter. Alternatively, artificial ageing of rice has been investigated by researchers to achieve similar results in lesser time and lower cost. binding capacity & water absorption capacities all varieties were determined in every two weeks up to four months. The rheological behavior of the material supply was studied, and the scientific rationale behind the printability of starch is discussed in detail. Significance and novelty Cooked fresh (0.7 month) was used as a reference. However, the head rice yield of rice undergone thermal processing was significantly lower than that of the naturally aged paddy. It contains most of the vitamins and micronutrients of rice. Most changes are time and temperature dependent and their effects on grain quality are irreversible; mostly being beneficial. However, this characteristic deteriorates rapidly during dry storage. By comparing the protein profiles from the seeds aged for 0, 10 and 25 days, a total of 91 and 100 protein spots were found to show a significant change of more than 2-fold (P < 0.05) in abundance, and 71 and 79 protein spots were identified, in embryos and endosperms, respectively. About 36.4–44.4% decrease in total soluble sugars at 45 °C and 9.30–31.8% increase in total soluble sugars were observed at 10 and 25 °C during six months storage of these cereal grains. Root length decreased from 0 hr control to 120 hr treatment, and was lowest in Fajr and Khazar. The survey reports have shown that toxigenic fungi and mycotoxins before and post-harvest, milling and storage of rice and its products are the main focus of the previous studies. Malondialdehyde (MDA) was selected to represent a secondary byproduct of lipid peroxidation during rice ageing. Rice stored at 40°C and 80% relative humidity for 60 days, which was sensorially evaluated as old rice, showed a significant difference in cooking quality and texture of when cooked as compared with 4°C-stored rice. Rice is available in over 5000 varieties, of which Basmati rice occupies a prime position on account of its extra long superfine slender grains, pleasant, exquisite aroma, fine cooking quality, sweet taste, soft texture, length-wise elongation with least breadth-wise swelling on cooking and tenderness of cooked rice.
