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.
Speaker 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
