ABSTRACT

The content of nutritional compounds, bioactive and antioxidant capacity of quitoquito (Solanum quitoense Lam) were determined in the present investigation. Highlights the fiber content (1,87 ± 0,06%) and minerals such as potassium (40,6 ± 0,21 mg / 100 g) and iron (34,6 ± 0,21 mg / kg) which are founded in greater proportion, such as macro and microelements respectively. Among the bioactive compounds, the quitoquito fruit presented high levels of vitamin C (30,1 + 0,93 mg / 100g), total polyphenols (67,24 + 0,58 mg equivalent of gallic acid / 100 g) and carotenoids (0,74 + 0,07 mg β carotene / 100 g). The antioxidant capacity was determined by the DPPH, ABTS and FRAP methods, where the highest value corresponded to ABTS (888 ± 21,62 µmol trolox / 100 g) in relation to DPPH (280 ± 16,19 µmol trolox / 100 g) and FRAP (197 ± 12,59 µmol trolox / 100 g) in that order. The results obtained confirm that quitoquito is a promising source of nutritional and bioactive compounds to be used as a functional ingredient
