Abstract

This study was carried out to improve the preservation and the functionality of chicken legs. Three precipitation solutions of common solution(A), herb solution(B) and herb solution containing chitosan(C) were prepared. The chicken legs were treated with A, B and C solution, respectively, during 4 hours. And the chicken legs treated with each solution were stored at $7^{\circ}C$ for 8 days. The quality changes of each groups were examined by pH, total bacteria, VBN(volatile basic nitrogen) values and sensory evaluation. The pH values of three groups were not different. Chicken legs treated with C solution showed the lowest VBN values and total bacteria cell count and the highest sensory scores in color and flavor.

본 연구는 키토산을 첨가한 한방액에 침지하여 보존성과 기능성을 갖는 튀김닭을 만들 목적으로 닭고기 다리를 보통 침지액(A액), 한방 침지액(B액) 그리고 한방과 키토산 침지액(C액)에 4시간 침지한 다음, $4^{\circ}C$에서 8일까지 저장하면서 닭고기 다리의 pH의 변화,휘발성염기질소량의 변화, 총 세균수의 변화 및 관능검사 등을 실시하였다. 그 결과는 다음과 같다. 침지액 A, B, C의 닭고기 다리의 pH변화는 초기와 8일후까지 3구 모두 큰 변화는 없었다. 휘발성 염기질 소량은 침지액 A와 침지액 B에 비해 침지액 C가 약간 낮은 것으로 나타났으며, 총 세균수의 변화에 있어서도 A와B액에 비해서 C액에서 낮은 cfu (log/g)를 나타내어 미미하지만 보존성이 있는 것으로 나타났다. 그리고 관능 검사에서도 침지액 C가 색과 냄새면에서 가장 좋았다.
