Abstract

This study was carried out to investigate the microencapsulation characteristics of squid liver oil according to various ratios of wall materials and squid liver oil. The emulsion stability and the water binding capacity increased with an increase in wall materials contents. The microencapsulation efficiency was found to be in the order of 7:3>4:6>3:7>5:5>6:4 by mixing ratio of wall materials and squid liver oil; also, ratio of 7:3 was found to be inappropriate because the oil content in the powder was not sufficient. Regarding the fatty acid composition, the content of polyunsaturated fatty acid was found to be over 50% in all treatment groups. The ratio of polyunsaturated to saturated fatty acid of the powder was the highest (2.13) at the mixing ratio of 4:6.

피복물질과 오징어 간유의 혼합 비율에 따른 미세캡슐화 특성을 알아보았다. 유화액의 점도와 안정성은 피복물질의 함량이 높을수록 증가하는 경향을 나타내었고, 미세캡슐화 효율은 43.86$\sim$29.49%로 7:3>4:6>3:7>5:5>6:4의 순으로 나타났으나 7:3의 경우 분말내 oil 함량이 낮아 적절하지 않을 것으로 판단된다. 수분결합지수는 피복물질 함량이 낮을수록 낮은 수분결합력을 보였으며, 입자의 크기는 모두 10 ${\mu}m$ 이하로 나타났다. 지방산 조성은 모든 실험구에서 다가불포화지방산의 함량이 50% 이상이었으며, 또한 다가불포화지방산에 대한 포화지방산의 비율은 모든 혼합비가 2.10 이상으로 높게 나타났다.
