Resumo: | The object of this present work was to determine the levels of soluble solids, total acidity and pH in raw and roasted grains of eight cultivars most commonly cultivated in the South of Minas Gerais, and determine the influence of roasting on these parameters. Fruits of Mundo Novo, Topázio, Catuaí Vermelho, Catuaí Amarelo, Acaiá Cerrado, Rubi, Icatu Amarelo and Icatu Amarelo were collected in Fazenda Experimental de São Sebastião do Paraíso da Empresa de Pesquisa Agropecuária de Minas Gerais. The fruits were dry with all the parts creating the known coffee as natural. The toasted grains were obtained by clear roasted, determined visually. The analysis of the results allowed to observe differences in the levels of soluble solids and pH for all the variable studied, in raw and toasted grains. Both cultivars Icatu Amarelo (H 2944) and Acaiá Cerrado presented larger values of the pH in the raw grains and the smallest ones in the toasted grains. The levels of soluble solids were larger in the toasted grains of the cultivars Mundo Novo and Rubi, the smallest values observed for the raw grain were in cultivars Topázio and Rubi. The total acidity showed differences only in toasted grains. There was an increase in the total acidity with the roasting, and reduction in pH values and soluble solids, which showed variation among all cultivars. It was observed that cultivars presented differences in chemical composition, and variations different from this composition with the toasted process. |
