Abstract

TUPINAMBA, Daiva Domenech et al. Pulp yield and mineral content of commercial hybrids of yellow passion fruits. Braz. J. Food Technol. [online]. 2012, vol.15, n.1, pp.15-20. ISSN 1981-6723.  https://doi.org/10.1590/S1981-67232012000100002.

Physical analyses and an analysis of the mineral content were carried out by peroxide-perchloric wet-digestion, taking readings using inductively coupled plasma-atomic emission spectrometry (ICP-AES) and measurements using an analytical balance and digital paquimeter, of three commercial hybrids of Passiflora edulis f. flavicarpa Deg.: BRS Sol do Cerrado, BRS Ouro Vermelho and BRS Gigante Amarelo, cultivated and harvested from the experimental area of Embrapa Cerrados, Planaltina, DF, Brazil, in October/2007. Eighteen fruits were evaluated for each hybrid, and presented weights and dimensions superior to those found in the scientific literature, without significant differences between the hybrids. Sol do Cerrado showed less weight loss post storage when compared to the other hybrids, but no significant differences were found with respect to the other physical parameters studied. The mineral contents found in the hybrids were higher than the values found in the scientific literature and in the Brazilian food composition tables (TACO) elaborated by NEPA-UNICAMP. The Sol do Cerrado had a higher iron content than the other hybrids. The hybrids are excellent sources of minerals, especially in comparison with the frozen pulp sold in supermarkets.

Keywords : Passiflora edulis; Physicochemical properties; Elemental composition; Health; Functional foods.
