초록

본 연구는 시판되는 닭튀김류의 지방함량과 지방산 조성, 트랜스 지방산함량 및 산가를 조사하기 위해 총 20종을 대상으로 분석하였다. 그 결과는 다음과 같다. 20종의 닭튀김에서 추출된 지방함량은 $4.94{\sim}18.06%$의 다양한 범위를 나타내었다. 이러한 지방함량의 분포는 닭 자체의 지방함량이나 닭을 튀긴 기름의 종류, 튀김온도, 시간, 튀김옷의 성분차이 등 다양한 요인에 의한 차이라고 생각된다. 조사된 닭튀김의 주요 지방산 조성은 palmitic acid, stearic acid, oleic acid, linoleic acid 등이었다. 포화 지방산 중에서 palmitic acid($10.67{\sim}25.43%$)가 불포화지방산 중에서는 oleic acid($29.78{\sim}67.85%$)와 linoleic acid($8.42{\sim}39.54%$)가 가장 많았다. 식품 100 g당 함유되어 있는 트랜스 지방산 함량은 0.1 g 이하의 낮은 함량을 보여주었으며 닭튀김에 함유된 지방을 추출하여 산가를 측정한 결과 20종의 닭튀김의 결과치는 식품공전상 튀김식품의 산가 규격을 초과하지 않는 양호한 결과를 나타내었다.

This study was conducted to investigate the fat content, fatty acid composition, trans fatty acid content, and acid value of twenty types of fried chickens purchased in local markets in Korea. The fat was extracted from the fried chickens and analyzed by the folch method, which revealed that the content ranged from 4.94% to 18.06%. The major fatty acids in the fried chickens were oleic acid ($29.78{\sim}67.85%$), linoleic acid ($8.42{\sim}39.54%$), and palmitic acid ($10.67{\sim}25.43%$). Twenty types of fried chickens contained less than 0.1 g of trans fatty acid per 100 g of chicken, while the fatty acid value ranged from $0.86{\sim}2.65$, which is lower than the KFDA criteria.
