Studies on Palatability of Rice in Northern Kyushu : V. Influence of abnormal weather in 1993 on the palatability and physicochemical characteristics of rice

Abstract

Under the low air temperature and the insufficient solar radiation conditions in 1993, the influence of the abnormal weather on palatability and physicochemical characteristics of rice were studied. Palatability of rice produced in 1993 was lower compared to rice produced in 1992. Milled rice produced in 1993 showed higher protein and amylose contents, and lower maximum viscosity and breakdown values than those of rice produced in 1992. The deterioration of palatability was due to the increase of protein and amylose contents and the decrease of maximum viscosity and breakdown values. There was a positive relationship between maximum viscosity and palatability.
