There was no difference (p > 0.05) for the content of vitamin C
between the maturity stages (Table 2). Despite the vitamin C not
differ between the maturity stages, Chitarra and Chitarra (2005)
mentions that usually occurs a reduction in vitamin C values of
the fruits during ripening, due to the direct action of the ascorbic
acid oxidase (ascorbinase) enzyme, or by the action of oxidizing
enzymes such as peroxidase. The content of vitamins in vegetables
is quite varied, depending on the species, maturity stage, harvest
season, genetic variations, post-harvest handling and storage conditions
(Correia, Faraoni, & Pinheiro-Santana, 2008). Other variations
can occur on the quantifying of vitamin C caused by the
determination method used, as the titratable, for systemic errors
may occur as a problem to visualize the end point of titration that
confers the pink coloring of the solution, however the fruit used in
this study possessed yellow coloration, keeping it easy to see the
changing of color in the solution.
