Characterization of polyphenol and sugar contents in standard beverages from green and roasted coffee in southern Minas Gerais
Several works have been developed to relate the chemical and physicochemical components of grains with coffee quality. The present work evaluated the polyphenol as well as the total, reducing, and nonreducing sugar contents of grains in relation to the quality of the coffee beverage (strictly soft, soft, just soft, hard, riada, and rioy). The arabic coffee (Coffea arabica) analysed was from southern Minas Gerais, Brazil. The polyphenol content of green coffee decreased with roasting. The total, reducing, and nonreducing sugars significantly varied with beverage quality. The sugar content had no clear relation with beverage quality. The sugar content decreased with roasting.
