对吉林省小粒大豆进行了多项生化品质成分分析研究，结果表明：①小粒大豆品种在蛋白质及氨基酸含量上均高于大粒大豆品种，平均分别高出２８２％和１５４％；脂肪含量低于大粒大豆各品种，但小粒大豆的脂肪酸组成中，亚油酸含量较高，比大粒大豆平均高出５０９％；小粒大豆亚油酸与亚麻酸配比合适。②小粒大豆的总糖含量低于大粒大豆，其还原糖含量却高于大粒大豆，平均高出０６１％；小粒大豆各品种粗纤维含量高于大粒大豆，平均高出１０３％。③小粒大豆的钙、锌含量分别比大粒大豆高４３８２３μｇ／ｇ、１１５３μｇ／ｇ，铁的含量比大粒大豆低，镁的含量基本一致。④吉林小粒２号在许多生化指标上最为优越，其蛋白质含量达４４６６％，蛋白含量与脂肪酸含量之和达６２５５％，谷氨酸、天门冬氨酸、亮氨酸、赖氨酸、精氨酸等氨基酸含量最高，还原糖含量最高，达５９２％。 The results showed that: ① The content of protein and amino acid of small-sized soybean was higher than that of large-grain soybean with an average of 282% and 154% higher respectively; However, the content of linoleic acid was higher in the fatty acid composition of small soybean than in large soybean, which was 509% higher than that of large grain soybean. The ratio of linoleic acid and linolenic acid in small grain soybean was suitable. ② The total sugar content of Soybean was lower than that of Soybean and the content of reducing sugar was higher than that of Soybean, which was 0.61% higher on average. The content of crude fiber of Soybean was higher than that of Soybean and the average was 1.33% higher. ③ The content of calcium and zinc in small-sized soybean was 43823 μg / g and 1153 μg / g higher than that of large-size soybean, and the content of iron was lower than that of big-grain and soybean, and the content of magnesium was basically the same. ④ Jilin Xiaoyu 2 was the most superior in many biochemical indexes, with a protein content of 4466%, a sum of protein content and fatty acid content of 6255%, glutamic acid, aspartic acid, leucine, The contents of amino acids such as acid and arginine were the highest, while the content of reducing sugar was the highest (592%).
