Abstract Brown rice was exposed to 60Co source at 0, 2, 4, 6, 8 or 10 kGy doses and the effect of gamma irradiation treatment on physicochemical properties were investigated. L* value of brown rice was decreased with increase of irradiation dose, whereas a* and b* values increased. The results showed the decrease of kernel hardness, amylose content and pasting properties considerably with irradiation treatment. A-type diffraction pattern was observed in non-irradiated and irradiated rice samples and crystallinity was decreased with irradiation dose. Raman spectrometry showed the decrease of Raman band intensity at higher irradiation doses. Thermal properties of rice samples were decreased slightly after irradiation treatment. Pearson’s correlation studies revealed that irradiation dose was positively correlated with b* value and negatively correlated with amylose content and pasting properties.

The effects of germination on physicochemical, morphological and rheological properties of rice starch from germ-remaining polished rice (GRPR) have been investigated. The properties of starches from raw GRPR, brown rice and germinated brown rice were also characterized as the comparison. The results showed that a decrease in amylose content was observed after germination and the amylose content of germinated GRPR was lower than that of germinated brown rice. Scanning electron microscopy did not reveal any distinct difference in the appearance of the starches except some slight alteration of the starch granule edges. Rheological investigation illustrated that the starches of GPRG with lower amylose content showed lower peak G’ in the four rice samples.
