Avaliação do efeito da quantidade de polifenois e análises físico-químicas e a percepção de características sensoriais de diferentes estilos de cervejas artesanais gaúchas

Abstract

Currently, craft beers have cornered the market and has gained a large number of consumers. Thus, the need for studies on the drink is important. With the Rio Grande beer market expanding, we were used 6 styles beers of the Rio Grande do Sul for the study: Standard American Lager, Red Ale, Pilsen, Wiess, and Porter India Pale Ale (IPA). It was verified consumer preference, the composition, the polyphenols and antioxidant activity in the samples of each beer style. For sensory analysis, participated in 54 untrained subjects and 8 tasters experts to compose the trained panel. Consumers preferred the Pilsen beer, however, the trained panel preferred the IPA. The beer was less preferred Standard American Lager style (and trained consumer panel). Regarding the polyphenols, the beers with higher total polyphenols and antioxidant activity were Porter (EAG 1,618/ml and 5,578 mM Trolox/ml, respectively) and Red Ale (EAG 0,946/ml and 3,232 mM Trolox/ml, respectively). Have beer with less polyphenols and antioxidant activity was the Standard American Lager (0,346 EAG/ml and 1,742 mM Trolox/ml, respectively) which also had the lowest acceptance trained judges and group of consumers.
