Beer is described as a drink susceptible to changes, so any modification in the production process will cause variations in the sensory profile and chemical composition. Alcohol removal during low-alcohol beer production may significantly influence the quality of the beverage. Development and physicochemical characterization of low-alcohol beers from modified processes were performed in this study. In order to obtain low-alcohol beers, modifications were carried out in stages of the production process, in relation to malt concentration, malt processing, and mashing temperature. Fractional factorial design was applied at two levels to an optimization study, demonstrating that only the parameters of extract content and alcohol content were significant, with systematic influence of these factors in the response. Alcohol content showed results of 4.93% in the standard beer and 0.97−2.35% in the samples with low-alcohol content.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
