Resumen
Descripción
The Atlantic Forest has species of native fruits, consumed fresh and processed, which have an important contribution to food sovereignty of families that consume it. This study examined the physical and physicochemical characteristics, proximate composition, concentration of carotenoids, vitamin C, vitamin E and minerals in the pulp and kernels of fruits of licuri ( Syagrus coronata (Mart.) Becc.). Titratable acidity was analyzed by volumetric neutralization, soluble solids by refractometry, proteins by the micro-Kjeldahl method, lipids by gravimetry using soxhlet, dietary fiber by non-enzymatic gravimetry, carotenoids and vitamin C by HPLC-DAD, vitamin E by HPLC-fluorescence, and minerals by ICP-AES. Pulp were a source of Zn (0.95 mg 100 -1 ), a good source of fiber (6.15 g 100 -1 ), excellent source of provitamin A (758.75 RAE 100 -1 ), Cu (0.69 mg 100 -1 ), Fe (3.81 mg 100 -1 ), Mn (3.40 mg 100 -1 ) and Mo (0.06 mg 100 -1 ). The kernel were a source of Fe (3.36 mg 100 -1 ) and excellent source of Mn (6.14 mg 100 -1 ), Cu (0.97 mg 100 -1 ) and Mo (0.07 mg 100 -1 ). The nutritional value and wide availability of licuri fruit make it an important resource for reducing food insecurity and improving nutrition of the rural population and other individuals who have access to it.
