Squid oil is an abundant source of polyunsaturated fatty acids. This is particularly true for eicosapentaenoic acidand docosahexaenoic acid. The principal objective of this study was to extend the stability and improve the processaptitude of squid liver oil. Fluidized bed coatings were employed for coating with microencapsulated oil. The efficiencyof the fluidized bed coating of the microencapsulated powder was over 90%. The apparent density with zein-DP was 0.6g/mL, thereby indicating that flow ability had been improved as the result of an increase in specific gravity. The solubilityof artificial gastric and enteric fluids with HPMC-FCC was 59.9 and 0%, respectively, whereas with zein-DP solubility was0 and 31.0%, respectively. Polyunsaturated fatty acid retention results demonstrated that zein-DP coating was higher thanHPMC-FCC, followed by the microencapsulated squid liver oil method. These results demonstrated that the application ofmicroencapsulation and fluidized bed micro-coating techniques improved the stability and processing compatibility of squidliver oil.

오징어 간유 미세캡슐화 분말을 HPMC-FCC, zein-DP로 코팅하여 유동층 코팅 특성을 살펴본 결과, 유동층 코팅 효율은HPMC-FCC, zein-DP 모두 90%의 효율을 나타내었다. 겉보기 밀도는 zein-DP 코팅분말이 0.6g/mL로 높게 나타나 코팅 분말의비중이 커져 흐름성이 개선되었음을 확인할 수 있었다. 인공위액과 인공장액에 대한 용해성을 살펴본 결과, HPMC-FCC는 각각59.9%와 0%를 나타내었고 zein-DP는 각각 0%와 31.0%를 나타내어 코팅재료에 따라 용해성을 조절할 수 있었다. 저장 안정성은 zein-DP나 HPMC-FCC로 코팅한 분말이 미세캡슐화 분말보다높은 PUFA/SFA 잔존율을 보여, 유동층 코팅 기술이 유지식품의안정성을 확보할 수 있는 새로운 기술이 될 수 있음을 확인할 수있었다.
