Abstract

A simple method has been successfully applied to extract squalene and its byproducts alkoxyglycerol from deep-sea shark liver oil. GC-MS was used to determine the extraction amount of the squalene and alkoxyglycerol, and the content of them in rough product and refined product were compared. The physical property of squalene was identified by measuring the pH value, peroxide value and iodine value. Under optimum extraction conditions, the amount of squalene and alkoxyglycerol increased 35.0% and 21.9%, respectively, while the amount of fatty acid decreased from 61% to 4%, especially, the amount of palmitic acid and oleic acid remarkably decreased. Large amount of peroxide and acid were removed from shark liver oil after refining process. Because squalene contains lots of double bond, so the value of iodine is much higher than squalane.

심해상어 간유에서 추출한 천연유지는 스쿠알렌(Squalene)과 알콕시글리세롤(Alkoxyglycerol)을 함유하고 있다. 본 연구에서는 심해상어 간유에서 피부 보호능력이 있는 스쿠알렌과 면역작용이 우수한 알콕시글리세롤을 추출하고 GC-MS 분석을 통하여 정제과정을 거친 스쿠알렌과 알콕시글리세롤의 함량 변화를 비교하고 스쿠알란과 함께 물성을 평가하였다. 스쿠알렌의 함량은 정제과정을 거친 뒤에 35% 더 증가하였으며 알콕시글리세롤의 함량은 21.9% 더 증가한 것을 볼 수 있었다. 상어간유를 알콕시글리세롤 정제과정을 통해 지방산은 61%에서 4%로 57%의 지방산이 제거된 것을 확인할 수 있었고, 지방산 중 Palmitic acid와 Oleic acid의 함량이 크게 감소된 것을 확인할 수 있었다. 상어간유에 과산화물가와 산가는 스쿠알렌 정제과정을 거친 후 크게 낮아진 것을 확인하였고 불포화 지방산이 이중결합이 많은 스쿠알렌이 스쿠알란(Squalane)보다 요도드가가 월등히 큰 것을 확인하였다.
