초록

유자의 부위별 narinign 및 hesperidin의 함량은 과피가 95.54 mg%, 103.99 mg%, 과육이 65.77 mg%, 77.18 mg%, 씨에는 16.49 mg%, 15.88 mg% 순으로 검출되었다 유자에서 고미의 원인 물질인 naringin을 제거하기 위한 naringinase 최적 첨가량을 검토한 결과, naringinase 20 units 첨가구의 경우 90분 경과후 대부분 분해되었다. 표준시약으로 naringin 10 mg%와 hesperidin 5 mg%의 기질에 naringinase 10.0 units와 hesperidinase 2.0 units를 각각 첨가하여 측정한 결과 0.11 mg%와 0.45 mg%로 감소하였고, naringinase 1% 처리구에서 0.54 mg% 와 0.09 mg% 감소하였으며, 탁주용 당화효소 5% 처리구에서는 0.26 mg%, 0.04 mg%로 감소하였다.
