Abstract

The content of naringin and hesperidin of Yuzu were 95.54 and 103.99 in peel ; 65.77 and 77.18 in flesh ; 16.49 and 15.88mg％ in seed, respectively. When 10 mg％ of naringin and 5 mg％ hesperidin were treated with 10.0 units naringinase and 2.0 units of hesperidinase, they were decreased to 0.11 and 0.45 mg％, respectively. One percent of Japanese naringinase digested naringin and hesperidin that their final concentration were 0.54 and 0.09 mg％ in 30 minutes, while 5％ Amorepacific enzyme did until 0.26 and 0.04 mg％, respectively.

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.
