Principles and recent applications of vacuum technology in the processing of dough-based cereal products: A comprehensive review

Cereal-based foods have been essential elements in nutrition throughout history. Recently, there has been an increasing interest in the application of innovative strategies to improve technological and nutritional properties of dough-based cereal products. Literature studies indicate that the integration of vacuum technology into baking and noodle industry can significantly enhance the quality and feasibility of final products. The vacuum has direct impact on gluten network, gas distribution and interaction of components in food matrix, especially due to aerated structure of dough systems. In this respect, this review for the first time presents a comprehensive evaluation regarding to use of vacuum technology in processing steps (i.e., mixing, baking, and cooling) of dough-based products in light of recent studies. The implementation of vacuum in the processes provide desired impacts on productivity and profitability for manufacturing industries. Vacuum application provides many advantages including improved product quality, nutritive value, extended shelf life, and reduced energy consumption.
