Maté (Ilex paraguariensis) Toasting Causes Chlorogenic Acids to Degrade and Incorporate into the Backbone of Melanoidins, Contributing to Their Antioxidant Activity
Abstract:Maté(Ilex paraguariensis) is a plant rich in chlorogenic acids (CGA) used to prepare teas elaborated with untoasted or toasted leaves. The present study was the first to investigate the effect of increasing toasting degrees, during actual industrial conditions, on matéCGA contents, their incorporation into melanoidins, and their relationship between matémelanoidins and antioxidant activity (AA). CGA contents decreased by up to 91% during toasting, and two lactones were formed. Melanoidins contents increased… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
