Quality Characteristics and Differences in Planting Regions of Typical Green-labelled Japonica Rice in Jiangsu Province
摘要
Abstract
To thoroughly investigate the effects of certification status and planting regions on the quality of japonica rice in Jiangsu Province,this study selected Nangeng 46 and Nangeng 9108,which were cultivated under both green certification and conventional planting methods,as the research objects.Samples were collected from the rice-growing regions of Southern Jiangsu,Central Jiangsu,and Northern Jiangsu,respectively.The principal component analysis method was employed to assess and evaluate the appearance quality,cooking and eating quality,as well as nutritional quality of the rice.The research results indicated that the protein content of green-certified Nangeng 46 and Nangeng 9108 decreased by 14.5％and 6.1％compared with that of rice grown under conventional methods,respectively.The planting region had a highly significant impact on the amylose content of japonica rice.For instance,the amylose content of Nangeng 46 planted in Southern Jiangsu increased by 12.9％compared with that in Central Jiangsu;the amylose content of Nangeng 9108 planted in Central Jiangsu increased by 7.6％compared with that in Northern Jiangsu(P＜0.01).In terms of amino acid and beneficial mineral content,there were no significant differences among certification status,planting regions,and rice varieties.The results of the principal component analysis showed that the quality of green-certified japonica rice had stronger regional specificity.In Southern Jiangsu,the protein content of green-certified Nangeng 46 decreased by 20.7％compared with Nangeng 46 grown under conventional methods,but its taste value increased by 16.0％;in central Jiangsu,the chalkiness degree of green-certified Nangeng 9108 decreased by 13.5％compared with Nangeng 9108 grown under conventional methods.The findings of this study provide valuable reference for the high-quality development of the green rice industry.关键词
