不同生长环境对稻米食味品质的影响

Effect of Different Growing Environment on Taste Quality of Rice

通过对吉林省优质水稻品种及主要推广品种在不同生长环境条件下进行稻米品质指标分析与食味测试结果表明:①种植在吉林稻区品质优于通化稻区,其碾米品质中精米率、整精米率平均值高于通化地区。蛋白质含量和直链淀汾含量低于通化稻区。②通过米饭食味测试结果,吉林稻区米饭硬度分值低于通化地区,外观、黏性、平衡度及食味分值高于通化稻区。综合食味明显优于通化地区。③在中部稻区和西部稻区影响食味主要因子是蛋白质含量,直链淀粉含量对食味影响不明显;东部稻区影响食味主要因子是蛋白质含量和直链淀粉含量。

Rice quality index and taste testing of quality rice varieties and main popularized varieties in Jilin province were studied. The results showed that rice quality planted in Jilin city was better than that in Tonghua region. Its milling quality such as average milled rice rate and head rice rate was greater than that in Tonghua region. The protein content and amylose content were lower than those in Tonghua region. By analy- sis of taste quality test, hardness value was lower than that in Tonghua region. Appearance, adhesiveness, balance and taste evaluation were higher than those in Tonghua region. Comprehensive taste was markedly superior to that in Tonghua region. Protein content was main factor affecting taste value of rice grown in middle and west part of Jilin province, whereas amylose content has no obvious effect on taste. In eastern region of Jilin province, protein content and amvlose content were main factors affecting taste.
