초록
고추장을 직립성 용기에 담아 숙성보관시 곱이 발생하는 것을 방지하기 위하여 햇빛을 쪼여 표면을 관리하는 것이 일반적이나 이 경우 표면층 고추장이 건조되고, 적색이 흑변되고, 유동성이 상실되며, 과염도 및 이물질 오염 등으로 인하여 많은 양이 비가식화되는 문제가 있어 왔다. 숙성 보관중 표층 고추장의 악변에 의한 손실을 최소화할 수 있는 숙성 조건을 조사하기 위하여 표면을 3가지 방법(무처리, 소금뿌림, PE-film덮기)으로 처리한 후 각각 햇빛을 쪼이면서 숙성한 경우(A, B, C)와 A, B, C와 같이 처리한 후 뚜껑을 덮어 숙성(A', B', C')시키면서 15일 간격으로 수분, 염도, pH, 점도, 퍼짐성(찍음성), 색도, 곱의 발생유무를 조사 비교하였다. 2일에 1회 햇빛을 쪼이면서 120일간 숙성시킨 경우(A, B, C)곱은 발생되지 않았으나 수분함량 감소
To minimize the waste amount of surface layer kochujang during aging, the effects of the three finishing methods(nothing, salt scatering and Polyethylene film on the kochujang surface) and sunning(conventional aging method) or nonsunning aging(cap covering) on water content, redness and spreadability, film forming yeast occurance and salinity of surface layer kochujang during 120 days aging were investigated. In the case of sunning aging, film forming yeast was not visually found on the surface. The surface layer kochujang was so low spreadability(zero) and very high salinity(18-30%) that could not eat. However, the aging method after PE-film covering on the kochujang surface, and then cap covering(nonsunning) was very effective in keeping of soundness of surface layer kochujang without film forming yeast growth on the surface kochujang, especially was greatly effective in keeping of redness, moderate moisture content and spreadability. The PE-film and cap covering aging were effective in prevention of water evaporation and
