| Abstract (English): |
The purpose of this work was to analyze commercial açaí pulp and to correlate the contribution of vitamin C, total carotenolds and phenolic compounds with the antioxidant activity of there products besides the examination of the standard related to the quality of the obtained products. Analysis were made with regard to pH, acidity total, soluble solids, sugars, color, water activity, vitamin C, total anthocyanins, total carotenoids, antioxidant activity and phenolic compounds. All parameters analyzed showed significative difference among the marks not added with preservatives and sucrose. The afar fruit can be considered a fair source of vitamin C and good source of natural antioxidants. In regard to the correlation with the antioxidant activity only the total anthocyanins and the total camtenoids presented positive and significative correlation. [ABSTRACT FROM AUTHOR] |

Este trabalho objetivou caracterizar polpas comerciais de açaí, além de correlacionar a contribuição da vitamina C, carotenóides totais e compostos fenólicos com a atividade antioxidante desses produtos, verificando ainda os parâmetros referentes à qualidede dos produtos obtidos. Foram realizadas anélises de pH, acidez total titulével, sólidos solúveis totais, açúcares, cor, atividade de égua, vitamina C, antociaminas totais e carotenóides totais, atividade antioxidante e compostos fenólicos. Conclui-se que todos os parâmetros apresentaram diferença significativa entre as marcas não adicionadas de conservante e sacarose. O açaí pode ser considerado uma importante fonte de vitamina C, bem como uma grande fonte de antioxidantes. Em relação à correlação com a atividade antioxidante, somente as antocianinas totais e os carotenóides totais apresentaram correlação positiva e significativa. [ABSTRACT FROM AUTHOR] |
