본 발명은 오징어 간유로부터 정제 어유 수득 방법에 관한 것으로, 유지 가수분해 억제 환경 기반 알카라인 반응 및 저분자 유기화합물의 액상 흡수 반응을 이용한 오징어 간유로부터 정제 어유를 수득할 수 있는 방법에 관한 것이며, 더욱 자세하게는 유지의 자동 산화 및 열 산화에 의해 산패된 오징어 간유로부터 유지 가수분해 억제 환경을 조성하여 유지의 산화를 방지하며 기 발생 된 유리지방산 및 기타 산화물, 산 패취 등을 완벽히 분리 제거할 수 있는 오징어 정제 어유 수득 방법에 관한 것이다.The present invention relates to a method for obtaining purified fish oil from squid liver oil, and more particularly, to a method for obtaining purified fish oil from squid liver oil using an alkaline reaction based on a fat hydrolysis inhibition environment and a liquid absorption reaction of a low molecular organic compound, From the squid liver oil, which has been corroded by automatic oxidation and thermal oxidation of the oil, it is possible to prevent oxidation of the oil by forming an environment to inhibit hydrolysis of the oil and to completely remove the free fatty acids and other oxides and acid patches from the squid. And a method of obtaining the same.

오징어 간유는 종래 양어장 및 새우 양식 사료 생산 업체에서 오징어 내장을 가열하여 상층부에 부상된 유지를 수거하여 생산된다.Squid liver oil is produced by the fish farms and the shrimp farming feed manufacturers by heating the squid gut and collecting floating oil in the upper layer.

한편, 다환 방향족 탄화수소는 200 여종의 유도체 화합물들이 알려졌으며, 발암성이 밝혀진바, 이 중에서도 벤조피렌(benzopyrene)은 특히 발암성이 강한 것으로 밝혀져 있다. On the other hand, polycyclic aromatic hydrocarbons are known to have 200 kinds of derivative compounds, and carcinogenicity has been revealed. Among them, benzopyrene has been found to be particularly carcinogenic.

벤조피렌은 발암물질로 탄소와 수소뿐만 아니라 질소, 황, 산소 등 다른 원소를 포함하고 있으며, 물에 대한 용해도는 낮고 기름에는 잘 녹는 특성이 있고, 연소하거나 고온의 열분해로 생성되는 특성이 있으며, 식품에서는 식품을 가열하는 과정에서 생성될 수 있는 물질로서 식품을 고온에서 조리하거나, 가공 조리 시 식품의 주성분인 탄수화물, 단백질, 지방 등이 불완전 연소하여 생성되는 것으로 특히, 숯불구이에 의한 육류, 훈제제품 등에서 벤조피렌이 많이 생성되어 검출되었으며 압착 유지, 커피 등 고온처리한 가공식품과 고온 조리식품에도 벤조피렌이 많이 함유되어 있하는 것으로 알려졌다.Benzopyran is a carcinogen that contains not only carbon and hydrogen but also other elements such as nitrogen, sulfur and oxygen. It has low solubility in water, good melting property in oil, and combustion or high temperature pyrolysis. Is a substance that can be generated during the process of heating foods, and is produced by incompletely burning foods, such as carbohydrates, proteins, and fats, which are the main constituents of food during processing at high temperatures, and particularly in meat, smoked products And benzo - pyrene were found to be produced in high - temperature cooked foods such as squeezed oil, coffee, and coffee.

오징어 간유 제조과정에서 벤조피렌이 기준치 이상 검출되는 경우가 빈번하고, 벤조피렌을 줄이기 위한 노력을 하고 있지만, 구체적인 벤조피렌의 감축 방안 및 벤조피렌의 생성경로에 대한 데이터베이스가 부족한 실정으로 벤조피렌의 함량을 제어하기 힘든 실정이다.In the process of producing squid liver oil, benzo-pyrene is often detected more than the standard value, and efforts are made to reduce benzopyrene. However, there is a lack of a database on specific benzoprene reduction and a pathway for producing benzopyrene, to be.
