The world's demand for plant protein consumption is increasing, but their application in different foods is limited due to their low techno-functionality. Direct steam injection heating (DSIH) is a promising technique to modify the structure and functionality of proteins, and it has been widely used in sterilization of milk. However, its application in producing plant protein ingredients is seldom. This review summarizes recent research on using DSIH to process dairy and plant-based proteins and suggests future research perspectives.
The world's requirement for plant protein consumption is increasing. However, their application in different foods is limited due to their low techno-functionality. Heating is the most widely used method to improve the functionality of proteins. Compared to indirect tubular or plate heating methods, direct steam injection heating (DSIH) can heat the sample much faster, thus modifying the structure and functionality of protein differently. It is used in the sterilization of milk to minimize the heat-induced denaturation of whey proteins and the loss of volatiles. By contrast, its application in producing plant protein ingredients is seldom. This review summarizes recent research using DSIH to process dairy-and plant-based proteins and proposes future research perspectives. DSIH is a promising technique for producing functional protein ingredients. It is of particular interest to overcome the techno-functional hurdles of plant protein blends using DSIH to improve their behavior in different food matrices.
