Abstract The objective of this work was to produce dark chocolates with the addition of coffee husk flour (CHF) and to evaluate the generated effects on their physical, physicochemical, microbiological, textural, and rheological characteristics. Husks of the Pacamara coffee (Coffea arabica) variety, produced under organic management, were used. The samples were previously dried, ground, and sieved at 0.250 mm. Five chocolate formulations were previously standardized at 55% content of cocoa solids (mass and cocoa butter) and at 0.4% soy lecithin. The addition of CHF was tested at the concentrations of 0, 2.5, 5.0, 7.5, and 10%, using a completely randomized design and three replicates. The addition of CHF up to 10% alters the physicochemical, textural, and rheological properties of the chocolate formulations, but without compromising their composition and quality. The tested formulations only differed regarding hardness and cohesiveness, evaluated in the texture profile. The hardness of the chocolate formulations increases as CHF is added. Resumo O objetivo deste trabalho foi produzir chocolates amargos com adição de farinha de casca de café (CHF) e avaliar os efeitos gerados nas suas características físicas, físico-químicas, microbiológicas, de textura e reológicas. Foram utilizadas cascas da variedade de café (Coffea arabica) Pacamara, produzida com manejo orgânico. As amostras foram previamente secas, moídas e peneiradas a 0,250 mm. Cinco formulações de chocolates foram previamente padronizadas em 55% de teor de sólidos de cacau (massa e manteiga de cacau) e em 0,4% de lecitina de soja. A adição de CHF foi testada nas concentrações de 0, 2,5, 5,0, 7,5 e 10%, tendo-se utilizado delineamento inteiramente casualizado e três repetições. A adição de CHF até 10% altera as propriedades físico-químicas, de textura e reológicas das formulações de chocolate, mas sem comprometer sua composição e sua qualidade. As formulações testadas diferiram apenas quanto à dureza e à coesividade, avaliadas no perfil de textura. A dureza das formulações de chocolate aumenta à medida que a CHF é adicionada.
