Caracterização dos resíduos da polpa do maracujá-amarelo.

This research evaluated the juice yield, arils and seeds of yellow passion fruits aiming to identify the potential of adding values for the seeds used in the oil extraction. It was measured the weight, peel color, size and shape of the fruit, juice yield, seeds, arils, number of seeds per fruit and humidity of seeds. The data were interpreted by confidence intervals at P≤0.05 for samples of an infinite population of fruits. It was verified that the juice yield increased with the ripening, but it was not changed by the shape and fruit size. The proportion of arils and seeds was higher in ripe fruits with smaller size. The seed yield was lower in bigger fruits, but it was not changed by the fruit shape, presenting average of 4.23% of seeds with 14.8% humidity. The estimated content of oil in seeds with 25.7 %db indicates a production of 64.84t of oil per year at the Rio de Janeiro state. [ABSTRACT FROM AUTHOR]
