| Resumo: | The production of fruits’ pulps has reached growing regional and international market. This is basically due to the fact that they are easily available to the consumers together with the benefits of a rich diet with substantial antioxidant activity. Even more, the properties of phenolic compounds and powerful antioxidant potential of fruits are associated to the human health. This work aimed to determine the antioxidant activity of the pulps from commercial fruits (mulberry, grape, açaí, guava, strawberry, acerola, pineapple, mango, graviola, cupuaçu and passion fruit) applying the method: ORACFL. The total polyphenol content (PT), the total flavanol content (TF) and the total anthocyanin (TA) were evaluated with the object of assessing the contribution for the antioxidant capacity. The acerola and mango pulps contained a high amount of total polyphenols (580.1 and 544.9mg/100g respectively) while mulberry and grape were the pulps which presented the highest amount of anthocyanins (41.8 and 30.9 mg/100g); strawberry and acerola were the pulps that presented higher amount of flavanol (83.4 and 75.8mg/100g). In addition, higher values of flavanoles corresponded to the strawberry and acerola pulps. The antioxidant activity determined by ORAC FL in pulps of frozen fruits is presented in the following order: acerola> strawberry> mango> grape> açaí >graviola> guava> cupuaçu> passion fruit> pineapple> mulberry. |
