Abstract
This study aimed to evaluate the physico-chemical composition and bioactive compounds of pulp and the peel of the pitomba arising from the state of Sergipe/Brazil. The income, the physico-chemical characterization, mineral content, vitamin C and carotenoids of pulp and pitomba peel were determined. The peel presented high income (44,60% of the fruit). A significant amount of vitamin C (20,68 ± 2,93 mg/100g of fresh sample) and carotenoids (43,56 ± 2,04 μg/mL of the extract) were observed in the pulp, while the peel had a high mineral content, mainly potassium (223,00 ± 2,00 mg/100g), calcium (78,90 ± 0,40 mg/100g) and magnesium (47,50 ± 0,90 mg/100g). The constituents’ knowledge of the peel and pulp of the pitomba in natura adds value to the fruit, since it allows a better use of it, considering that the peel is discarded and only its pulp is consumed.

Physical-chemical characterization The determination of ash, moisture, proteins, carbohydrates, total soluble solids (TSS), pH and total titratable acidity (TTA) was performed according to the Association of Official Analytical Chemists techniques (AOAC 1995), and lipid content was analyzed according to the methodology described by Bligh and Dyer (Bligh and Dyer 1959)
Summary
There is a growing interest in the study of exotic fruits that are part of the Brazilian culture and are still little explored scientifically. Fruits are important sources of vitamins, minerals, fibers and water, as well as providing nutrients that, when consumed regularly, can act in mechanisms involved in reducing the risks of diseases such as obesity, diabetes, hypertension, dyslipidemia, cardiovascular diseases and some types of cancer (Brasil 2016, Coradin et al 2011). As an example of these fruits still little studied there is the Talisia esculenta St.Hill.) Radlk, whose tree is popularly known as “pitombeira”, belong to the Sapindaceae family, whose fruit is the pitomba. Its consumption is predominantly distributed in the North and Northeast regions of Brazil (Santos et al 2012, Giulietti et al 2004, Brasil 2018)
