牦牛不同脏器中牛磺酸提取工艺优化及含量分析

Comparison of content and optimization of extraction process of taurine in the yak organs

随着牦牛屠宰加工业的发展,产生了大量以脏器为主的副产物,为综合利用这些屠宰副产物,采用均匀实验设计优化牦牛不同脏器中牛磺酸的最佳提取工艺,并采用紫外可见分光光度法对青海海北牦牛心脏、肝脏、肾脏和肺脏中牛磺酸含量进行分析。研究发现,牦牛脏器中牛磺酸最佳提取工艺为:料液比1∶3(m∶v),自溶温度55℃,提取温度75℃,提取时间60min。青海省海北地区牦牛肝脏中牛磺酸含量最高为(7.02±0.50)mg/g,其次为肾脏(5.59±0.25)mg/g、肺脏(4.46±0.17)mg/g和心脏(2.50±0.30)mg/g。研究表明,牦牛脏器中牛磺酸含量丰富,可以进行相关的精深加工。

With the development of yak industry,there producing more and more viscera byproducts. In order to comprehensively utilized these viscera byproducts,extraction optimization of taurine extract from yak viscera was carried out using uniform design method,and the content of taurine was determined by ultraviolet-visible spectrophotometry. It was found that maximum yield of taurine was obtained when meal/solvent ratio,autolysis temperature,extractive temperature and extractive time were 1∶3 （m/v）,55℃ ,75℃ ,60min. Furthermore ,the maximum taurine contents was （7.02±0.50）mg/g in yak liver,while （5.59±0.25）mg/g in kidney,（4.46±0.17）mg/g in lung and （2.50±0.30）mg/g in heart. It was shown that yak viscera byproducts had abundant taurine for further processing.
