Abstract:
The edible fruit species of the genus Passiflora L. are important for their nutritional value, health-promoting components, and medicinal properties. Nutrient composition studies of the rare and lesser common Passiflora species remain central to assess their potential health benefits. In this work, pulp extracts of P. alata Curtis (sweet passion fruit), a species from Brazilian, Colombian and Peruvian Amazon, were analyzed to determine provitamin A and vitamin C contents using High Performance Liquid Chromatography (HPLC) and the results were compared with those obtained for P. edulis f. edulis Sims (purple passion fruit). On a fresh weight (fw) basis, P. alata and P. edulis f. edulis contain 3591 g/100 g and 4346 g/100 g, respectively, of provitamin A (all- trans-β-carotene). Therefore, the vitamin A content of P. alata measured in retinol activity equivalents (RAE) is 299.3 g RAE/100 g (5985 IU/100 g) and that of P. edulis f. edulis is 362.2 g RAE/100 g (7243 IU/100 g). The total amount of vitamin C (acid L- ascorbic and dehydroascorbic acid) found in P. alata was 5.78 mg/100 g and P. edulis f. edulis was 19.12 mg/100 g. Our results indicate that consumption of sweet passion fruit and purple passion fruit could provide meaningful amounts of vitamin A and vitamin C, which would contribute to achieve the recommended daily intake for both vitamins.
Biography:
Juan Manuel Parra Gomez is a final year undergraduate student at National University of Colombia, Colombia, South America. He is expected to receive his Chemical Engineer degree in september 2019. He joined the bioproducts research group of Susana Hernandez at the same university in february 2016 to work on the identification of Ganoderma species from Colombia, cultivation of Pleurotus mushrooms, and quantification of vitamin C and provitamin A in Passiflora species cultivated in Colombia, using HPLC. The purpose of the bioproducts research groups is to provide information that can be applied in biotechnology to solve health and nutrition problems
