Abstract

Cubiu fruits (Solanum sessiliflorum Dunal, Solanaceae) are nutritionally dense. However, most studies have investigated cubiu nutrients in whole fruits. This study evaluated cubiu fruit nutrients as a function of different tissues (peel, pulp, and placenta) and ripening stages (green, turning, ripe, and fully ripe). Fruits (n = 118) were harvested to investigate weight, macronutrients (moisture, ash, proteins, lipids, carbohydrates, and energy) and selected macrominerals-calcium (Ca), magnesium (Mg), phosphorus (P), and potassium (K). Analyses were performed at the Instituto Nacional de Pesquisas da Amazônia (INPA), Brazil. Macronutrient results were expressed in g/100 g fresh weight, macrominerals as g/kg fresh weight. Fruit weight increased throughout ripening. Moisture reached a maximum value (91.77) in the fully ripe pulp. Ash displayed a maximum value (0.86) in the fully ripe placenta. Energy reached a maximum value (356.66 kJ, 86.57 kcal) in the fully ripe placenta. Carbohydrates decreased from the peel to the placenta (lowest values). K exhibited a maximum value (42.257) in the green pulp. The P peaked in ripe pulp (24.450) and placenta (21.240). In the ripe placenta, Ca had a maximum value (7.860) followed by Mg (7.573). This detailed knowledge of the edible parts of ripening cubiu fruits will broaden their use in health and disease.
