 Abstract
This study examined the optimal salting drying method and processing conditions (salt concentration, curing time, dry temperature, and drying time) for preparing salted semi-dried common gray mullet (SSD-CGM) Mugil cephalus based on the moisture content, salinity, and overall acceptance using response surface methodology (RSM). The moisture content, salinity, and overall acceptance of SSD-CGM prepared with different salting methods revealed that dry salting was the optimal salting method for preparing high-quality SSD-CGM. The optimal drying method for preparing high-quality SSD-CGM based on the drying velocity and sensory color was hot air-blast drying. The results of the RSM program indicated that the optimal independent variables (, salt concentration; , curing time; , dry temperature; , drying time) based on the dependent variables (, moisture content; , salinity; , overall acceptance) for high-quality SSD-CGM were 5.6% for , 2.7 h for , for , and 8.5 h for for uncoded values. The predicted values of , , and for SSD-CGM prepared under optimal conditions were 54.4%, 4.2%, and 6.3, respectively, while the experimental values were , and . The actual and predicted values did not differ.
