摘要
为挖掘国产高粱品质和质量优势,通过对国产与进口高粱、国内不同产区、不同生产环节的高粱品质与质量进行比较分析。结果表明:国产与进口高粱比较,国产高粱酿造品质优于进口高粱。国产高粱单宁含量平均值是进口高粱的39倍,蛋白质平均含量较进口高粱高0.24百分点;北方与南方高粱比较,南北方存在显著性差异,北方高粱蛋白质含量较南方高0.63百分点,淀粉含量较南方低2.20百分点,单宁含量低0.50百分点;产地来源比较,重庆市和黑龙江省高粱单宁含量较高(分别为1.49%、1.46%),辽宁省和内蒙古单宁含量较低(分别为0.81%、0.60%);贵州省高粱淀粉含量最高(71.90%),吉林省高粱淀粉含量最低(63.98%);山西省和内蒙古高粱蛋白质含量较高(分别为10.18%、10.74%),吉林省高粱蛋白质含量最低(9.15%)。
In order to tap into the quality potential of domestic sorghum,the quality of sorghum cultivated in China and imported from abroad was compared,and the quality of domestic sorghum obtained from different regions and different production links was analyzed.The results showed that brewing quality of the domestic sorghum was superior to the imported one.The average content of tannin of domestic sorghum was 39 times higher than that of the imported one,and the average content of protein was 0.24 percentage point higher than that of the imported sorghum.To compare the sorghum grown in the north and south of China,the protein content of sorghum grown in the north was 0.63 percentage point higher than that of in the south,and the starch content was 2.20 percentage point lower,as well as 0.50 percentage point lower of the tannin content.Test of significance showed that significant differences existed between the quality of sorghum grown in the north and the south.In comparison with the sorghum of different origins,the tannin content of sorghum in Chongqing and Heilongjiang were higher(1.49%and 1.46%,respectirely),Liaoning and Inner Mongolia were lower(0.81%and 0.60%,respectively),while the starch content of sorghum in Guizhou was the highest(71.90%).On the contrary,it was determined the lowest starch content in Jilin province(63.98%).The protein content of sorghum were higher(10.18%and 10.74%,respectively)in Shanxi and Inner Mongolia,while recorded the lowest in Jilin(9.15%).
