| 摘 要： | 以产品的产率、效率和贮存稳定性 (包括产品的抗氧化性和心材的持留率 )为评定指标 ,选用多种蛋白质 ,如明胶 (GEL)、浓缩乳清蛋白 (WPC)、大豆分离蛋白 (SPI)、大豆水解蛋白 (SPH)和酪蛋白酸钠 (CAS)等 ,作为 EPA、DHA微胶囊化壁材 ,并进行了比较。结果表明 :SPI作为壁材制得的微胶囊产品具有较高的产率和效率 ,但其贮存稳定性很差 ;而 GEL、SPH(DH8)和 WPC 3种壁材制得的产品具有较好的贮存稳定性 ,其中又以 GEL为最佳。

| Abstract: | Various proteins, such as gelatin, whey protein concentrate(WPC), soy protein isolate(SPI), soy protein hydrolyzate (SPH) and sodium caseinate(CAS), were evaluated as microencapsulating agents of EPA and DHA, based on the encapsulation yield(EY)、encapsulation efficiency(EE) and the storage stability (including the antioxidant effect and the retention of the core material). Microencapsulation of fish oil with SPI and CAS was not so effective in storage stability as that of gelatin、SPH(DH8) and WPC. Microencapsules with the best storage stability were prepared from gelatin. |

| Keywords: | microencapsulation EPA and DHA fish oil gelatin storage stability |
