摘 要:对麦芽根的营养成分、活性成分、消化率等指标进行测定与分析,并与麦麸的营养成分进行对比,结果表明:麦芽根中蛋白质(34.3%)、膳食纤维(39.4%)含量高于麦麸,必需氨基酸含量(8.37 g/100 g)为麦麸(4.03 g/100 g)的2倍,赖氨酸、苏氨酸、缬氨酸含量相对较高,粗蛋白消化率为80.04%,高于麦麸(74.08%)。麦芽根中维生素B2、B6、叶酸、B12、维生素C含量高于麦麸,分别为0.6 mg/100 g、0.46 mg/100 g、0.17 mg/100 g、0.11μg/100 g、4.35 mg/100 g,并含有维生素E(3.14 mg/100 g)。钠、钾、钙、锌、铜、磷、铁、镁含量丰富,并具有较高含量的总多酚(1.09%)及少量多糖。同时,从饲料、食品、化妆品三个领域分析其法规现状、应用现状及前景,为麦芽根副产物的高值化利用提供依据。In this paper,the nutritional composition,active ingredients,and digestibility of malt roots were measured and analyzed and compared with those of wheat bran.The results showed that the content of protein(34.3%)and dietary fiber(39.4%)in malt roots are higher than those in wheat bran.The content of essential amino acids(8.37 g/100 g)is twice than that of wheat bran(4.03 g/100 g).The content of lysine,threonine and valine are relatively high in malt roots.Additionally,malt roots not only contain vitamin E(3.14 mg/100 g),but also have a higher content of vitamin B2,B6 and B12,folic acid,and vitamin C than those in wheat bran(0.6 mg/100 g,0.46 mg/100 g,0.11μg/100 g,0.17 mg/100 g,4.35 mg/100 g,respectively).Furthermore,the malt roots are rich in sodium,potassium,calcium,zinc,copper,phosphorus,iron,and magnesium.It also contains a high content of total polyphenols(1.09%)and a small amount of polysaccharides.At the same time,the regulatory status,application status and application prospect were analyzed from the feed,food and cosmetics fields,which provided a basis for the high-value utilization of malt root by-products.
