猪脑水解液的制备及其生物学活性研究

The Preparation and Biological Activity of Hydrolysate of Swine Brain

研究了猪脑水解液的制备及其生物学作用。结果表明:猪脑水解液含有17种氨基酸,其中包括8种必需氨基酸,总氨基酸含量为10493.9mg/L。实验组小鼠服用本品6天后,避暗试验和跳台试验的错误率明显下降(P<0.01),实验组大鼠服用28天后其脑重和雌性大鼠实验组血红蛋白水平显著高于对照组(P<0.05),雌性实验组大鼠在游泳30min后,血乳酸含量明显低于对照组(P<0.05)。提示猪脑水解液不但对脑营养价值高。

The purpose of this study was to prepare and to determine the biological activity of hydrolysate of swine brain. It was found that there were 17 kinds of amino acids including 8 kinds of essential amino acids in the hydrolysate of swine brain. It contains 1049.39mg/dL of total amino acid. It was found that the error rate in step through and step down test were significatly lower than that of the control (p<0.01). The brain weight of the rats fed with hydrolysate of swine brain for 28 days and the Hb level in female experiment group were higher than that of control group (p<0.05). The level of lactic acid in the serum was lower than that of control group after female experiment group had swam 30 min (p<0.05). These results indiated that hydrolysate of swine brain was not only high in nutritional value for the brain but also may promote animal memory ability and enhanced constitution.
