Abstract

This study was carried out to investigate the effect of ultrasound treatment on the quality, amino acid and fatty acid composition of fried chicken meat The moisture content of raw chicken meat was higher than fried chicken meat, but the crude protein and fat were lower than those of fried chicken meat The moisture and crude fat of ultrasonic fried chicken meat were higher than those of control. The crude protein of breast meat was higher than leg meat, but the moisture and crude fat were lower than leg meat The ultrasonic treatment did not affect on calorie of the fried chicken meat The pH of leg meat was higher than breast meat, and the fried loss of breast meat was higher than leg meat Frying loss of the leg meat was higher than that of control when ultrasonic treated The Hunters $L^{\ast}$ value of ultrasonic treated breast meat was higher than control, but the leg meat were not significantly different between ultrasonic treatment and control. The $a^{\ast}$ value of leg meat was higher than breast meat, and $b^{\ast}$ value of breast meat was higher than leg meat And the $b^{\ast}$ value of ultrasonic treatment was higher than control. The glutamic acid and aspartic acid were major amino acids in chicken meat The palmitic acid $(C_{16:0})$ and oleic acid $(C_{18:1})$ by fried were decreased, and the linoleic acid $(C_{18:2})$ was increased But the fatty acid composition by ultrasonic treatment were not changed.

본 연구는 초음파가 튀김 닭고기의 품질, 아미노산 및 지방산 조성에 미치는 영향을 검토하기 위하여 실시하였다. 수분함량은 생육이 튀김 닭고기보다 높았으며, 조단백질 및 조지방 함량은 튀김 닭고기가 높았다. 초음파 튀김 닭고기의 수분 및 조지방 함량은 대조구보다 높았다. 그리고 가슴육의 조단백질 함량이 다리육보다 높았으나, 수분 및 조지방 함량은 더 낮았다. 칼로리는 다리육이 가슴육보다 높았으나 초음파에 의한 영향은 없었다. 그리고 pH는 다리육이 높았고, 튀김감량은 가슴육이 다리육보다 높았다. 가슴육은 초음파에 의한 튀김 감량의 영향은 없었지만 다리육은 초음파 처리구가 대조구보다 낮게 나타났다. 색도의 결과에서 가슴육의 $L^{\ast}$값은 초음파 처리구가 대조구보다 높았으나 다리육은 차이가 없었다. 그리고 $a^{\ast}$값은 다리육이 높고, $b^{\ast}$값은 가슴육이 높았으며, 초음파 처리구의 $b^{\ast}$값이 대조구보다 높은 경향이었다. 아미노산 조성은 glutamic acid와 aspartic acid가 많이 함유되어 있었다. 지방산 조성은 튀김에 의하여 palmitic acid$(C_{16:0})$ 및 oleic acid$(C_{18:1})$는 감소하고, linoleic acid$(C_{18:1})$는 증가하였다. 그러나 초음파 처리에 의한 지방산 조성의 변화는 없는 것으로 나타났다.
