초록

회분처리법으로 박층류식 평막 test cell에 의한 재래간장의 한외시험을 실시한 결과 공급액 주입속도별 투과유속의 감소는 용량감소율의 대수값에 비례하여 감소하였고 본 연구에서 사용한 분획분자량 200,000 dalton의 막에 의한 재래간장의 한외여과에서는 1.5L/min의 유속으로 공급액을 주입하는 것이 농도분극화현상을 최소화하면서 장시간 작업할 수 있음을 알 수 있었다. 간장의 한외여과시험에서 간장내의 총질소와 소금성분은 투과유속이 빠를수록 막에 의한 저지율이 더 높아졌고 따라서 500 nm에서의 간장의 흡광도는 더 낮아졌으며 Cu, Mn 및 Mg와 같은 무기성분도 다소 저지되었다. 미생물 균체는 공급간장의 유속에 상관없이 분획분자량 200,000 dalton의 한외여과막으로 100% 저지되었으나 유리아미노산은 거의 저지되지 않아 투과됨을 알 수 있었다.
