DOI: 10.1016/j.lwt.2020.110301
Abstract: Abstract Phytochemicals are dietary compounds considered lifespan-essentials. Their beneficial effects strongly depend on their bioaccessible quantities, in turn determined by food matrix components. Organosulfur compounds (OSCs) are renowned phytochemicals responsible for garlic health-effects. Currently, garlic… read more here.
