Abstract: For improving functionalities of wheat gluten protein,its physical modification by ultrasonic was studied. Based on the solubility index,single factor tests were done at first to estimate the proper ranges of main affecting factors,and then the factors were optimized based on central composite design theory of Uniform precision. The results showed that under the conditions of substrate concentration 8.8%,ultrasonic power 720 W,ultrasonic time 8 min and pH 8.5,the solubility reaches 4.11 mg/ml.

Key words: wheat gluten protein, ultrasonic, functionality, solubility
