常温储藏对6种优质稻谷品质的影响

以常温储藏1年及未储藏的甬优9号、甬优12号、甬优15号、甬优1540、秀水134、嘉花1号为研究对象,对其进行新鲜度、脂肪酸值、食味品质、发芽率等储藏指标分析.结果表明,在稻谷水分为11.8％～13.4％的条件下,2017年收获的优质稻谷常温储藏1年后与2018年收获的相同品种优质稻谷比较,其新鲜度、食味品质、发芽率...

The Influence of Conventional Temperature Storage on the Quality of 6 High-Quality Rice

This work analyzed Yongyou 9,Yongyou 12,Yongyou 15,Yongyou 1540,Xiushui 134,Jiahua 1 with or without conventional temperature storage for one year and compared their fresh degree,fatty acid value,cooking and eating quality and germination rate.With rice moisture content between 11.8%to 13.4%,the highquality rice harvested in 2017 was compared with the same variety of high-quality rice harvested in 2018.As a result,fresh degree,cooking and eating quality and germination rate were decreased to various degrees while the fatty acid value increased after one year of storage.The results showed that indica-japonica hybrid rice was more resistant to storage than japonica type rice,and the storage quality of late japonica rice Xiushui 134 and Jiahua 1 declined the fastest,followed by japonica hybrid rice Yongyou 9 and indica japonica hybrid rice Yongyou 12.Indica-japonica hybrid rice Yongyou 1540 and Yongyou 15 had the smallest change and best storage resistance.
