Uniform experimental design was applied to study the effects of using high pressure and the treatment time on water holding capacity of pork homogenate gelation.The results showed that soluble protein concentration of homogenate and water holding capacity rate of gelation were increased while the pressure and the treatment time decreased.The trend of the dehydration rate of pork homogenate gelation was varied by different conditions.With longer high pressure treatment,the dehydration rate was increased along with the increasing of the pressure;but at the shorter treatment time,the result was inversed.If the pressure is fixed,the dehydration rate was increased first and then decreased along with treatment time.
