| Abstract This study aimed to evaluate the efficiency of aqueous extraction to obtain bioactive phytochemicals from grains and residual husk of organic Arabic coffee, as well as to develop a beverage with high antioxidant capacity and assess its sensorial acceptability. Aqueous extracts were obtained from dried and crushed coffee beans and husk. Various extraction methods were used to select the one capable of extracting the most amount of total phenolic constituents. The decoction without mechanical agitation was highlighted as the best method, from which the chemical characterization, antioxidant capacity and the presence of antinutrients were investigated. Three beverage formulations were prepared with coffee husk extract and added in different... |

| ABSTRACT Green manures are an alternative for substituting or supplementing mineral nitrogen fertilizers. The aim of this study was to quantify biological N fixation (BNF) and the N contribution derived from BNF (N-BNF) to N levels in leaves of coffee intercropped with legumes grown on four family farms located in the mountainous region of the Atlantic Forest Biome in the state of Minas Gerais, Brazil. The following green manures were evaluated: pinto peanuts (Arachis pintoi), calopo (Calopogonium mucunoides), crotalaria (Crotalaria spectabilis), Brazilian stylo (Stylosanthes guianensis), pigeon pea (Cajanus cajan), lablab beans (Dolichos lablab), and velvet beans (Stizolobium deeringianum), and spontaneous plants. The experimental design was randomized... |
