Green process intensification techniques for bio-refinery

Bio-refinery could be a new concept to meet the challenges of the 21st century, to stop the commonly used one cultivationone product paradigm, and, therefore, permits valorization of majority of secondary and primary metabolites of a plant matrix. This article presents innovative food processing techniques (such as microwave, ultrasound, pulse electric field, Instant controlled pressure drop, and supercritical fluid processing) and their role in promoting bio-refinery. We will pay special attention to strategies and tools available to make extraction greener and present them as success stories for research, education, and at industrial scale.
