불포화지방산의 함량이 많은 오징어 간유의 미세캡슐화 공정을 최적화하기 위하여 부형제 조성을 달리하여 미세캡슐화 특성을 살펴본 결과, 모든 조성비에서 유화액의 점도는 유사한 경향을 나타내었고, Na-caseinate의 함량이 높을수록 유화안정성이 증가하였다. 미세캡슐화 효율은 Na-caseinate와 cyclodextrin의 비율이 4:6 > 6:4 > 5:5 > 3:7 > 7:3의 순으로 4:6 비율이 가장 높게 나타났으나 미세캡슐화된 분말의 흡

This study investigated the effects of microcapsule wall materials and mixing ratios on the characteristics of microcapsules containing squid liver oil Emulsion stability was increased as Na-caseinate levels lose. Changes in mixing ratios of Na-caseinate and cyclodextrin caused micioencapsulation efficiencies to rise, fall, and then rise again. The particle size aid moisture contort of microencapsulated powders were not affected by the mixing ratios of wall materials. As the cyclodextrin content rose, water uptake was increased. The polyunsaturated fatty acid composition was shown to be higher then 50% in all powders, and the ratio of polyunsaturated fatty acid composition to saturated fatty acid composition was. 2.11 when the Na-caseinate and cyclodextrin mixing ratio was 4:6.
