SUMMARY
Correlation between antioxidant activity and bioactive compounds of açaí (Euterpe oleracea Mart) comercial pulps
The purpose of this work was to analyze commercial açaí pulp and to correlate the contribution of vitamin C, total carotenoids 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 açaí 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 carotenoids presented positive and significative correlation.
Key-words: Açaí, chemical and physical chemical analysis, antioxidant activity, pulp quality.
