南海海洋珍珠贝肉牛磺酸提取工艺初探

Analysis on Extraction of Taurine from Shellfish Wastes in South China Sea

牛磺酸是一类含硫的特殊氨基酸,是人体正常生长不可缺少的非蛋白质结构氨基酸,由于人体只能有限地合成牛磺酸,因此膳食中的牛磺酸就显得非常重要。珍珠贝肉经过混合酶解,脱色,过滤等过程得到酶解提取液,再经树脂纯化分离得到纯化液,测定各自的牛磺酸质量分数以及氨基氮质量分数。海洋珍珠贝肉中牛磺酸质量分数丰富,从珍珠贝肉中提取牛磺酸的工艺简单易行,是天然牛磺酸来源的良好途径,具有较大的开发价值。

Taurine,a sulfonated β amino acid, is not incorporated into proteins and is one of the most abundant free amino acid in mammalian tissue. It is an essential dietary constituent for the human as a result of limited biosynthetic capability. Shellfish wastes are dealt with the process of multi_enzyme hydrolysis, decolorizing, filtering and purifying with ion_exchange resin. The hydrolysate is determined the contents of taurine and amino nitrogen and the results indicate that taurine is present in high concentrations in shellfish wastes and the technology of distilling taurine from shellfish wastes is simple to operate and is valuable for exploiture.
