초록
본 연구는 표준화된 밀 메주를 제조하기 위해 원료밀의 도정에 따른 수침 및 증숙조건과 품질특성을 조사하였다. 수침시간에 따른 2분도 밀, 5분도 밀, 통밀, 밀가루의 물리적 특성변화를 조사하기 위해 무게, 부피, 수분 함량, 수분 흡수량을 살펴 본 결과, 대부분의 밀에서 수침 4시간 이후에는 평형상태에 도달하였다. 원료밀 종류에 따른 증숙시간을 조사한 결과, 통밀을 제외한 밀원료의 증숙시간은 100℃에서 10분이 적합하였다. 최적 수침 및 증숙조건으로, 가공한 2분도 밀과 5분도 밀을 각각 A. oryzae와 B. subtilis M1으로 발효하여 우리밀 메주를 제조한 후 일반 성분 및 효소역가를 비교한 결과, 황국균을 사용한 경우 발효 효율이 더 우수하게 나타났다. 또한 2분도 밀보다 5분도 밀에서 총당, 환원당 및 α-amylase 역가가 높게 나타나, 우수한 밀 메주의 제조를 위해 5분도 밀을 A. oryzae로 발효하는 것이 효율적이라 사료된다.
Abstract
This study was conducted to determine the effects of the pretreatment and infrared drying methods on the physicochemical properties and antioxidant activities of dried peaches. The pretreatment methods were the 30 min treatment of NaCl, vitamin C, and soluble Ca (1:5 w/v immersion ratio), and leaving them untreated before infrared drying at 55℃ for 20 hr. The moisture content was lower in the pre-treated group and was significantly lowest in the 0.3% NaCl. The titratable acidity and soluble solid content and acid ratio (SS/TA) were high for the vitamin C and soluble Ca groups. The browning degree and cutting strength of the dried peach were lower in the pre-treated group. The total sugar content in the 0.3% NaCl group was significantly higher than those in the vitamin C and soluble Ca groups. The Ca contents were more effective in the soluble Ca treated group and increased with higher Ca concentration. The sensory evaluation results indicated that the organoleptic scores for the overall preference were higher in the 0.1% vitamin C treated group. The phenolic compounds and ABTS radical scavenging ability were high for the 0.1% vitamin C and 0.1% soluble Ca treated groups. These results suggest that pretreatment affected the qualities of the dried peaches, showing that infrared drying can be applied to the production of high quality dried peach products.
