Abstract:
The quality degradation and reduced shelf stability of starch-based foods attributable to starch retrogradation have long stood as key constraints hindering the advancement of the starch deep-processing industry. In recent decades, electromagnetic technologies, embraced as highly efficient and eco-friendly physical modification approaches, have been widely applied to alleviate starch retrogradation in food matrices, exhibiting considerable potential for enhancing food quality and thus meriting extensive research focus. This review focuses on five representative electromagnetic technologies: pulsed electric fields, irradiation, radio frequency, inductive electric fields, and microwave. By examining the influence of starch's multi-scale structural hierarchy on retrogradation behavior, we systematically summarize the underlying anti-retrogradation mechanisms of electromagnetic fields and their impacts on starch structural properties. Additionally, we outline the current research landscape of electromagnetic technologies in inhibiting starch retrogradation and discuss prospects for their application. This research endeavors to establish a theoretical framework for modulating starch retrogradation and maintaining the quality attributes of starch-based food products.
