不同大豆品种蛋白质品质特性分析

Analysis of Protein Characteristic in Different Soybean Varieties

摘要:

本文以70个大豆品种为材料,分析了不同大豆品种的蛋白质品质特性及其指标间的相关关系。结果表明:供试大豆品种样本群体的平均蛋白含量、水溶性蛋白含量和蛋脂含量分别为40.20%、22.81%和63.77%。东北地区的大豆品种在此3项指标上均低于其他地区。供试大豆品种样本群体的平均7S和11S组分含量分别为21.97%和38.83%;平均11S/7S比值为1.77%。东北地区的7S和11S组分含量均低于其他地区。相关性分析表明:蛋白含量、水溶性蛋白含量和蛋脂含量3项指标间两两呈极显著正相关关系。蛋白含量与AS亚基呈显著正相关;水溶性蛋白含量与α亚基呈现显著负相关。

Abstract:

The soybean protein characteristic and the correlation in 70 varieties were analyzed.The results showed that the average protein content,the water-soluble protein content and protein-lipid content of the sample group were 40.20%,22.81% and 63.77%,respectively.The average protein content,water-soluble content and protein-lipid content from northeastern region were lower than other region.The average contents of 7S,11S and 7S/11S component were 21.97%,38.83% and 1.77%.The average 7S and 11S component contents from northeastern region were lower than other region.The average protein content,water-soluble protein content and protein-lipid content had a highly significant positive correlation.The protein content had a significant positive correlation with AS subunit.The water-soluble protein content had a significant negative correlation with α subunit.
