Surimi, a processed fish product, consists mainly of protein and water. Although surimi contains about 70% water, the concentrations of proteins are so high that surimi is quite viscous, taking the appearance of a gel. It is also rich in sugar. Several aspects were studied in order to apply a method of direct insertion of a pH glass membrane electrode in the special medium of surimi. The result shows that it is possible to measure pH by introducing a pH electrode directly. Fresh surimi pH values measured by direct insertion were in the range of 6.97-7.06. From these values it is concluded that the pH is partially due to myosin and action proteins and partially to sodium polyphosphates used as preservatives. The low pH value of surimi indicates bacterial putrefaction. The direct insertion method applied to defrosted surimi at 10°C was easier, more convenient, more accurate, and more reproducible with a quick response than the traditional method of aqueous extraction.
