摘要：本文研究了狐尾藻组和狐尾藻结合生物膜组处理富营养化水体后狐尾藻营养活性成分含量的变化。结果表明,狐尾藻组和狐尾藻结合生物膜组分别在粗蛋白、粗脂肪、α-亚麻酸、二十一碳酸、钙、锰、果糖和总黄酮含量存在显著差异(p<0.05)。两组样品中狐尾藻粗蛋白含量约为18.00 g/100 g,含有全部18种氨基酸;粗脂肪、水分、灰分和粗纤维含量均分别高于2.00 g/100 g、92.00%、124.00 mg/g和13.00%;总游离氨基酸含量分别为13.39和13.28 g/100 g,必需氨基酸含量分别占总游离氨基酸的33.91%和30.80%;必需脂肪酸含量较高,分别占总脂肪酸含量的73.10%和69.41%。两组样品中α-亚麻酸、钙、果糖、VB6、VB2、总黄酮含量分别为(12.103±0.12)和(9.284±0.035) mg·g^-1、(20.735±0.389)和(15.430±0.547) mg·g^-1、(27.00±0.15)和(19.30±0.10) mg·g^-1、(5.30±0.06)和(4.50±0.12) mg·(100 g)^-1、(1.48±0.45)和(1.44±0.002) mg·(100 g)^-1、(31.81±0.049)和(21.75±0.058) mg·g^-1。可见,狐尾藻含有种类较齐全的营养活性成分,在功能食品领域资源化利用前景十分广阔。
After eutrophic water by Myriophyllum aquaticum and Myriophyllum aquaticum combined with biofilm,the effects of Myriophyllum aquaticum and Myriophyllum aquaticum combined with biofilm on nutritional and active ingredients of Myriophyllum aquaticum were investigated respectively. The results showed that there were significant differences among the content of crude protein,crude fat,α-linolenic acid,heneicosanoic acid,Ca,Mn,fructose and total flavonoids in Myriophyllum aquaticum between the two treatments(p<0.05). The content of crude protein was about 18.00 g/100 g,and 18 kinds of amino acids were identified in Myriophyllum aquaticum. The contents of crude fat,water,ash and crude fiber were above 2.00 g/100 g,92.00%,124.00 mg/g and 13.00%,respectively. The total content of amino acids was 13.39 g/100 g and 13.28 g/100 g,and the ratio of essential amino acids to total content of amino acids was 33.91% and 30.80%,respectively. There were higher essential fatty acids in Myriophyllum aquaticum,and the ratio of total content of essential fatty acids to total fatty acids was 73.10% and 69.41%,respectively. The contents of α-linolenic acid,Ca,fructose,VB6,VB2,total flavonoids were(12.103±0.12)and(9.284±0.035) mg·g^-1,(20.735±0.389)and(15.430±0.547) mg·g^-1,(27.00±0.15)and(19.30±0.10) mg·g^-1,(5.30±0.06) mg·(100 g)^-1 and(4.50±0.12) mg·(100 g)^-1,(1.48±0.45)and(1.44±0.002) mg·(100 g)^-1,(31.81±0.049)and(21.75±0.058) mg·g^-1,respectively. Therefore,the nutritional and active ingredients in Myriophyllum aquaticum were complete,which indicated that Myriophyllum aquaticum has a good application prospect for resource utilization in the field of functional food.
