In order to understand physicochemical properties of water-soluble proteins obtained from crucian carp, turbidity, total sulfhydryl content, hydrophobicity and SDS-PAGE of crucian carp water-soluble proteins during heat treatment were investigated. Turbidity remained unchanged up to 44A degrees C and considerably increased from 46A degrees C to 54A degrees C, one peak of increase rate was found at 50A degrees C; total SH content decreased rapidly when heated from 50A degrees C to 55A degrees C; hydrophobicity increased sharply when heated up to 45A degrees C, indicating the conformation of water-soluble proteins from crucian carp began to unfold and expose the buried nonpolar amino acids at temperatures above 45A degrees C; analysis of SDS-PAGE indicating the formation of disulfide linkage of creatine kinase and glyceraldehy-3-phosphate dehydrogenase when the temperature reached 65A degrees C and 80A degrees C, respectively.
