Abstract:


Background: Cajuína is obtained through clarification of cashew apple juice (Anacardium occidentale L.), a non-diluted and non-fermented beverage, which is prepared from the edible part of the pseudo-fruit.

Objective: This study sought to identify and quantify phenolic compounds, determine vitamin C content, total flavonoid content, and the antioxidant activity of two commercial brands of clarified cashew apple juice (cajuína) produced in Piauí, Brazil.

Method: Spectrophotometric and high performance liquid chromatography were used.

Results: A high vitamin C content was found mainly in brand A. A high total phenolic content was observed in brand A, and there was no significant difference in flavonoid content between the two brands. Cajuína had high antioxidant activity, which was confirmed by two methods. The highest value was found for brand A by the DPPH method.

Conclusion: We concluded that this clarified cashew apple juice has a high antioxidant compound content, and it is a functional food.
