마늘장아찌 숙성 중 Alliinase 활성 변화에 관한연구

Changes in the alliinase activity during the aging of pickled garlic samples prepared by the several methods were investigated. The activity of alliinase in raw garlic was 8,37 units/mg protein. The ac-tivity in the garlic pickled with swoy sauce was reduced to 4.57 units/mg with 52% remaining by 1st week of pickling and to 1.05 units/mg protein with 12% remaining by 2nd week of pickling. The ac-tivity of alliinase in the garlic pickled with vinegar was 2.79 units/mg protein with 32% remaining by 1st week of pickling and was 0.26 units/mg protein only with 3% remaining by 2nd week of pickling. The activity of alliinase in the garlic pickled with 10% salt solution was 5.06 units/mg protein with 58% remaining by 1st week of pickling. After one week pickling the juice of pickled garlic was removed. Then garlics were pickled again with vinegar. The allinase acting in was reduced to 0.85 units/mg pro-tein with 10% remaining by 2nd week of pickling. The activity of alliinase in the garlic pickled with vin-egar was 2.79 units/mg protein with 32% remaining by 1st week of pickling. The juice of pickled garlic was removed after one week. Then the galics were again pickled with saysauce. The allinase activity in the garlic the garlic pickled again with soy sauce was reduced to 0.43 units/mg protein with 5% remain-ing by 2 week of pickling.
