Nutritional and bioactive compounds of Solanum quitoense Lam (Quito quito), native fruit from the andeswith high nutrients potential
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
