不同产地油菜籽氨基酸组成比较研究
目的 研究不同产地油菜籽中氨基酸水平的差异性。方法 参照GB 5009.124-2016, 用氨基酸自动分析仪检测长江上中下游鄂、苏、川、贵4省油菜籽中氨基酸。结果 四川省油菜籽总氨基酸含量最高, 为(24.47±0.22) mg/100 mg, 同时各产地油菜籽必需氨基酸含量占氨基酸总量均在33%以上, 其中湖北产地最高, 为34.30%。通过t检验得到两两产地不同氨基酸具有显著性差异, 其中半胱氨酸(cysteine, Cys)是差异性氨基酸中最显著的氨基酸。结论 不同产地油菜籽中蛋白质的氨基酸含量和组成有较大差异, 在加工过程中应选择适宜产地的油菜籽, 从而提高油菜籽的利用率。
Objective To study the differences of amino acids in rapeseed from different regions. Methods According to GB 5009.124-2016, amino acids in rapeseed from Hubei province, Suzhou province, Sichuan province, and Guizhou province in the middle and lower reaches of the Yangtze river were detected using an automatic amino acid analyzer. Results Sichuan province rapeseed had the highest total amino acid content of (24.47±0.22) mg/100 mg, and the essential amino acid contents of rapeseed in each producing area accounted for more than 33% of the total amount of amino acids, of which the highest in Hubei province was highest (34.30%). The t-test showed that there were significant differences in different amino acids between these producing areas, among which cysteine (Cys) was the most significant amino acid in the differential amino acids. Conclusion The amino acid content and composition of rapeseed protein in different places have great differences. In the process of processing, rapeseeds from suitable places should be selected to improve its utilization.
