RESULTS & DISCUSSION
Figure 1 shows the vitamin C content determined for “in nature” tropical fruits and the values found in the literature. Initially it was verified that “in nature” guava and papaya show vitamin C content lower than those mentioned in the literature, while the values obtained for pineapple and mango were higher and similar, respectively, as it can be seen in Figure 1. Regarding this analysis it is necessary to consider the geographic localization differences from the literature data, EUA, and the fruits studied in this work, Brazil. Nelson et al.
[12] found a range from 19.3 to 71.5 mg/100g AA in six strawberry cultivars from four locations. In addition, the vitamin C content in fruits can also be influenced by various factors such as genotype differences, climatic conditions, soil state, maturity at harvest and harvesting methods [1, 2]. The higher the intensity of light during the growing season, the greater is vitamin C content in plant tissue [2
