The second most consumed beverage worldwide is beer. In Brazil, the brewing market is in full expansion, which allowed the emergence of several microbreweries, which end up attrative a significant portion of the consumers of the large breweries, due to the fact that they provide differentiated products, using high raw materials quality and production methods specific to each style. In this context, the objective of this work was the development of a Blond Ale beer, with addition of pineapple pulp (Ananas comosus L. Merril). The physical and chemical attributes were: original and final gravity, alcohol content, total dry extract, total acidity, maltose reducing sugar, pH, color and degree of fermentation. The OG and FG of the beer produced were, respectively, 1.0455 and 1.0107, and the alcohol content was 5.24%. The results found are within the range allowed for a Blonde Ale style, according to the BJCP 2015 standard. Thus, the quality of the beer produced meets the proposed in the article.
Despite the technology available to agriculture, qualitative and quantitative losses occurring during post-harvest are still not controlled, and stored grains may undergo changes in their composition, due to storage conditions. This study aimed at determining the sensitivity of the alcoholic acidity and pH tests in soybean (GB 874RR cultivar) grains with different quality standards obtained during storage. A completely randomized design, in a 3 x 6 x 5 (3 storage conditions x 6 storage times x 5 methods) factorial scheme, was used. A correlation was observed among pH, total acidity content (r = 0.888) and grain quality parameters. Deterioration was identified based on the total acidity content, showing a high correlation with fungal incidence (r = 0.864), ether extract (r = -0.781) and electrical conductivity (r = 0.923). The use of phenolphthalein as indicator is more sensitive than pH 8.8. Among the pH determination methods, AOAC was the most suitable for assessing the quality loss during storage.
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.
