멸치분말의 저장안정성을 알아보고자 80 mesh이상, 80-60 mesh, 60-40 mesh로 입자크기에 따라 분급하여 흡습특성을 조사하고 평형수분함량의 예측 모델식을 수립하였다. 평형수분함량은 수분활성도가 높아짐에 따라 빠르게 증가하는 양상이었으며, 높은 온도에서 낮은 함량을 나타내었다. 단분자층 수분함량은 BET식보다 GAB식이 더 높은 유의성을 보였으며 그 함량은 0.022-0.029 g H2O/g dry solid 였다. 수분활성도가 증가함에 따라 필요로 하는 흡습에너지가 낮아져 흡습엔탈피는 감소하여 흡습이 쉽게 이루어짐을 알 수 있었다. 등온흡습곡선의 적합도는 Kuhn 모델이 R2 0.94 이상으로 높은 적합도를 나타내었고, Halsey, Caurie, Oswin 모델순으로 적합도를 나타내었다. 흡습 중 평형상대습도 예측 모델을 수립하기 위해 온도와 수분활성도의 경우 일차함수, 시간의 경우 ln 함수가 높은 적합도를 보였으며, 수분활성도 예측모델식은 입자의 크기에 관계없이 상대습도와 시간으로 수립한 모델식의 적합도가 적절한 것으로 나타났다.
Abstract
This study was carried out to estimate the moisture sorption characteristics and prediction model of anchovy powders with different particle size as above 80 mesh, 80-60 mesh and 40-60 mesh. The equilibrium moisture content had higher values at lower storage temperatures, and higher water activity. The monolayer moisture content calculated using the GAB equation showed a higher level of significance than that of BET equation. The estimated monolayer moisture content was 0.024-0.052 g H2O/g dry solid. The absorption enthalpy was calculated with different particle size and various water activities. It showed that the absorption energy was decreased with increasing water activity but no difference was found on particle size increasement. The fitness of the isotherm curve was shown to be in the order of Khun, Halsey, Caurie and Oswin model. The prediction model equations for the moisture content were established by ln(time), water activity, and temperature, respectively. The model equation will be helpful for future work on drying and storage of anchovy powder.
