Surface hydrophobicity of the solid state of Alaska pollack surimi was studied using a frontsurface viewing system of fluorometer. Fluorescence intensity of the surimi (excitation wavelength: 365nm, emission wavelength 470 run) was measured in the presence of ANS (sodium 8-anilino-naphthalene-1-sulfonate) raising temperature from 0°C to 80°C at a constant speed of 1.2°/min. The intensity was increased above ca. 35°C and reached a maximum, but decreased rapidly above ca. 55°C. By the addition of 3% sodium chloride to the surimi, the intensity was increased at every temperature and the temperature of the maximum intensity (Tm) was lowered. However, by the addition of 10% sucrose, the intensity was decreased and Tm was raised. This feature of the surimi added with the sucrose was somewhat cancelled by further adding of 3% sodium chloride. For every case, the intensity was proportionately increased by cooling the once heated surimi.
