Abstract

This study investigated changes in the quality properties of deep frying oil and fried chickens according to frying number. Acid values of frying oil and fried chicken after frying 110 chickens were 2.27 and 1.90, respectively. The peroxide values of frying oil did not increase uniformly as frying number increased. Conjugated dienoic acid value of frying oil and fried chicken after frying 110 chickens were 0.70 and 0.44, respectively. Regarding the fatty acid composition after frying 110 chickens, linoleic and linolenic acids decreased, whereas palmitic, stearic, and oleic acids increased. Contents of trans fatty acids in frying oil and fried chicken after frying 110 chickens were 0.75% and 0.45%, respectively. Contents of benzo [a] pyrene in frying oil and fried chicken after frying 110 chickens were 2.20 and 2.19 ${\mu}g/kg$, respectively. The quality properties of frying oil and fried chickens significantly decreased after frying 60 chickens.

본 연구에서는 닭튀김을 일정기간 반복 재사용했을 때, 닭튀김 횟수에 따른 튀김유 및 튀김닭의 품질 저하 정도를 비교, 검토하였다. 닭 110마리 튀긴 후의 튀김유 및 튀김닭의 산가는 각각 2.27 및 1.90이었으며, 공액 이중 산가는 각각 0.70 및 0.44였다. 과산화물가는 튀김 횟수에 따른 일률적인 증가를 보이지 않았다. 닭 110마리 튀긴 후 튀김유의 지방산조성을 보면, 리놀레산과 리놀렌산의 함량은 감소하고, 팔미트산과 스테아르산, 올레산의 함량은 상대적으로 증가하였다. 110마리 튀긴 후의 튀김유와 튀김닭의 트랜스지방산의 함량은 각각 0.75 및 0.45%이었으며, 벤조피렌의 함량은 각각 2.20 및 2.19 ${\mu}g/kg$으로 거의 차이가 없었다. 전체적으로 튀김유와 튀김닭의 품질은 닭 60마리 튀긴 후 현저하게 감소되었다.
