| 摘 要： | 对南海长松藻(Codium cylindricum Holmes)的主要营养成分进行了分析,结果显示:多糖、蛋白质和粗纤维是构成藻体的主要营养成分,占藻体干基的80%左右,其中多糖占55.57%、粗纤维占11.09%、蛋白质占12.57%,但脂肪含量仅为0.59%。水溶性营养成分较为丰富,水浸出物总量为34.55%,其中包括水溶性蛋白、水溶性多糖、游离氨基酸等。多糖是长松藻的主要有效成分。单因素及正交实验结果表明:长松藻多糖提取的最佳工艺参数为浸提温度95℃,浸提时间1.5 h,料水质量比1∶50,多糖得率为9.79%。

| Abstract: | Main nutrition constituents of Codium cylindricum Holmes from South China Sea were analyzed.Results showed that polysaccharides,crude protein and fiber were the chief constituents(80% or so)of the marine algae dry weight.The polysaccharides reached 55.57%,crude fiber,11.09% and protein,12.57%.There were higher content of water-solubility nutrition constituents.The contents of total water-solubility extracts were 34.55%.Water-solubility sugars,water-solubility proteins,free amino acids had substantial contents.Therefore,Polysaccharides are the main effective constituents of Codium cylindricum Holmes.The results of single factor and orthogonal experiments showed that at 95℃,1.5 h,the ratio of solvent to material(1∶50) resulted in maximum polysaccharides extraction yield(9.79%). |
