摘要：Corn starch-water suspensions were subjected to high hydrostatic pressure at 4000 atmospheres for different duration. Some samples were heat treated at 50°C water bath to facilitate starch gelatinization. Degree of starch gelatinization (SG) was determined by iodine method. The SG values were compared with that of boiled starch suspension. It was observed that preheating at 50°C was necessary to obtain gelatinization of starch by high hydrostatic pressure. The duration of pressure treatment increased the SG values. To treat the samples at 4000 atmospheres several times in one cycle rather than once would be useful to obtain higher SG values.
