饥饿对泥鳅肌肉水分蛋白总糖及脂类含量的影响

菜单

摘要：本实验研究了饥饿对泥鳅生化组成的影响，实验测定了饥饿时间0d、14d条件下泥鳅肌肉的水分、总糖、总脂和蛋白质含量。结果表明：饥饿0d、14d的泥鳅肌肉含水量分别为为60.50%、63.10%，两组泥鳅含水量差异均不显著（P﹥0.05）；饥饿过程中泥鳅肌肉含糖量呈上升趋势，饥饿0d为1.28%，饥饿14d后上升为2.81%，两组泥鳅总糖含量差异显著（P＜0.05）；总脂和蛋白质相对含量都是先上升，后下降，总脂饥饿0d、14d后含量分别为10.41%、7.13%，蛋白质饥饿0d、14d后含量分别为62.17%、47.32%，两组泥鳅的总脂和蛋白质含量均存在显著性差异（P＜0.05）。59749

Effects of Hunger on Muscle Contents of Moisture, Protein ,Total sugar and Lipid of Misgurnus anguillicaudatus.

Abstract: The study was conducted to determine the effect of hunger on the biochemical compositon of Misgurnus anguillicaudatus. Experiments were pided into two groups, hungering for 0d and 14d respectively, and the determination of the content of the muscle from Misgurnus anguillicaudatus, the content of the moisture of musle ,lipid, protein from which was in hungry of 0d and 14d. The results showed that along with the extension of hunger, the content of the moisture of muscle which was in hungry of 0d and 14d were 60.50%, 63.10% respectively. There were no significant differences（P﹥0.05）all of the two groups. The content of the saccharide of the muscle rised from 1.28% to 2.81% after 14d. There were significant differences all of the two groups（P＜0.05）. The content of the lipid of muscle which was in hungry of 0d and 14d were 10.41%，7.13%, and the content of the protein from muscle of Misgurnus anguillicaudatus which was in hungry of 0d and 14d were 62.17%，47.32% respectively.There were significant differences of the content of lipid and protein all of the two groups（P＜0.05）.

1．引言

泥鳅( Misgurnus anguillicaudatus) 属鲤形目，鳅科，广泛分布于我国南方各地的江河、湖泊、水库、池塘及沟渠中，北方不常见但也分布各地。泥鳅被称为“水中之参”，全年都可采收，夏季最多，泥鳅捕捉后，可鲜用或烘干用。该鱼生长快，食性杂，抗病力强，因其个体小且易得，经济效益高、饲养方法简易且花工较少等优点，所以已越来越受养殖户的欢迎，是一种十分适合养殖的经济鱼类，也是一种较理想的实验鱼材料。泥鳅道鲜美，营养丰富，含蛋白质较高而脂肪较低，能降脂降压，即是美佳肴又是大众食品，素有“天上的斑鸠，地下的泥鳅”和“水中人参”之美誉。美又滋补，还易获得，价廉物美。随着人们生活水平的提高，人们对泥鳅的需求量日益递增，野生泥鳅的产量已远远不能满足市场需求。
