Research progress and latest application of ultrasonic treatment on protein extraction and modification

Abstract The advancement of the modern food industry has prompted a shift away from traditional protein extraction methods due to their inherent limitations. As a result, there is a growing interest in exploring alternative methods for protein extraction and modification such as ultrasonic (US) treatment. This shift towards more sustainable and efficient protein extraction methods is a key research focus in obtaining safe proteins in an environmentally friendly manner. Furthermore, enhancing the functional properties of proteins through modification can expand their application. This paper reviews recent research progress and applications of US treatment on protein extraction and modification as well as the impact on protein structure and functional properties. In addition, the latest applications of ultrasound-modified-proteins, including nano-proteins, 3D printing and interactions between proteins and other food components, are reviewed. This review may provide some inspiration for the potential application of US technologies in food fields.
