Combined effect of pH and heating conditions on the physical properties of Alaska pollock surimi gels
Abstract Physical properties of Alaska pollock surimi paste were investigated as affected by pH (4.0 and 6.0–10.0) and heating conditions (slow and fast). The highest values of gel strength and deformability, as shown by breaking force and penetration distance, were obtained at pH 7.5–8.0, while the...
