Item Technological and nutritional aspects of dark chocolate with added coffee husk flour(Empresa Brasileira de Pesquisa Agropecuária - Embrapa, 2024-07-19) Borges, Marília Viana; Leite, Cristina Xavier dos Santos; Santos, Ingrid Alves; Leão, Danilo Junqueira; Ferrão, Sibelli Passini Barbosa; Santos, Leandro Soares; Lima, Amanda Beatriz Sales de; Wobeto, Carmen; Lannes, Suzana Caetano da Silva; Silva, Marcondes Viana daThe 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.Item Production, composition, fatty acids profile and stability of milk and blood composition of dairy cows fed high polyunsaturated fatty acids diets and sticky coffee hull(Instituto de Tecnologia do Paraná - Tecpar, 2014-07) Santos, Geraldo Tadeu dos; Schogor, Ana Luiza Bachmann; Romero, Jakeline Vieira; Lima, Luciano Soares de; Pintro, Paula Toshimi Matumoto-; Grande, Paula Adriana; Kazama, Daniele Cristina da Silva; Santos, Fabio Seiji dosFour lactating Holstein cows were assigned to a 4 × 4 Latin square design to determine the effects of feeding sticky coffee hull (SCH) as a source of antioxidants on dairy cows fed with high PUFA diets. The treatments (on DM basis) were control diet, diet with 30 g/kg of soybean oil, diet with 30 g/kg of soybean oil and 100 g/kg of SCH, and diet with 30 g/kg of soybean oil and 150 g/kg of SCH. Inclusion of 150 g/kg of SCH decreased the crude protein digestibility. Lower values of NDF digestibility were also observed when cows were fed with 100 g/kg and 150g/kg of SCH. The digestibility of NDT was lower in the control and 150 g/kg of SCH diets. Milk production and composition did not differ among the treatments. Inclusion of SCH increased the total polyphenols and flavonoids in the milk and reducing power as well. Soybean oil and SCH supplementation increased the LDL and total cholesterol concentration in the plasma. Milk fatty acid profile was barely altered by the treatments. In conclusion, the results confirmed that SCH added up to 15% in the diet did not alter milk production, improved its stability, and incorporated antioxidants substances in the milk, improving its quality for human health.
