Effects of Number of Washes and pH Adjustment on Characteristics of Surimi-like Materials from Pork Leg Muscle

초록

The effects of different washing time and pH adjustment of surimi-like materials from pork leg on quality characteristics were investigated. Surimi was made from pork leg by washing two or four times with water, as well as by pH adjustments of 3.0 or 11.0. The control surimi was made by two times washing from Alaska pollock. The content of crude protein was higher in the surimi manufactured from pork leg with pH adjustments. The highest gel strength was found in the control, and the control had greater lightness and whiteness value. The control had higher texture attributes than the other samples, whereas the surimi from pork leg made by a pH 11.0 adjustment had higher texture attributes than the pH 3.0 adjustment. The sensory color was higher in the control compared to other surimi samples, whereas aroma was lower in the control. However, there were no significant differences in overall acceptability among the surimi samples.
