Fermentation of Medicine-Food Homology substances by probiotics: a review from functions to mechanisms
摘要
Medicine-Food Homology (MFH) substances are originated from Traditional Chinese Medicine (TCM) with the dual attributes as daily foodstuffs and therapeutic agents. Traditional processing for MFH substances usually includes slicing, stir-frying, steaming and boiling, and often results in low bioavailability due to poor solubility, instability in digestion, and inefficient absorption. Probiotic-mediated fermentation has emerged as a promising biotechnological approach to substantially overcome these bottlenecks and further unlock the functional potential of MFH substances. The present review aimed to introduce a background and theory basis of MFHs, provide an up-to-date summary of characteristic bioactive constituents including polysaccharides, polyphenols and flavonoids, and comprehensively elaborate the regulation strategies and underlying mechanisms of probiotic-fermented MFH systems. The new perspectives on regulating and developing probiotic-fermented MFH products were also proposed. The outputs hopefully present a reasonable full framework to elucidate the functions and mechanisms for their application in next-generation personalized nutritional MFH products by probiotic fermentation.
