The Caja-manga is an exotic fruit with flavor and pleasant aroma, good-looking, nutritious and rich in carotenoids quality. Generally, it is grown in the North and Northeast of Brazil, it is a fruit that is well suited to the dry climate, but it is little researched within your family and gender. Presents bioactive compounds among which phenolic compounds and these are recognized for their beneficial health actions. Thus, the pulp of caja-manga was used in the preparation of fermented dairy drink with whey and prebiotic in order to increase the nutritional value of this drink, and also as an alternative to the use of whey in milk industries generated. The objective of this study was to evaluate the antioxidant activity of incorporated kefir pulp caja-manga. In pulp caja-manga and milk beverage was analyzed for total phenolic content using the Folin-Ciocalteu method and antioxidant activity by ABTS, FRAP and DPPH methods. The pulp of caja-manga showed value of total phenolic compounds 47,86 mg gálico/100g acid pulp and antioxidant activity by the three methods applied. In the analysis of phenolic drinks without pulp and 25% and 30% pulp of caja-manga, it was found that beverages with pulp had higher phenolic content than the drink without added. However, by the DPPH method was not observed capacity drink without pulp to kidnap the 2,2-diphenyl-1-picrylhydrazyl radical which indicates the lack of antioxidant activity. Beverages containing 25% and 30% of the pulp caja-manga showed antioxidant activity by the DPPH method without significant difference between them at p < 0,05 probability by Tukey test. However, the FRAP and ABTS methods have been unable to demonstrate antioxidant activity for these beverages. In this study, the probiotic fermented milk beverage showed antioxidant activity due to the bioactive compounds present in the pulp of caja-manga which contributes to the allegation functionality of this food. |
