Abstract(s)
The conversion of the agricultural explorations to more sustainable production technologies
intends to reduce the impact of the agricultural activities on the environment and improve the
hygienic-sanitary quality of the food products. However, in relation to this last aspect, the
available scientific information about the food quality differences between different production
forms is quite scarce in general and particularly in what respects to the citrus.
The investigation work consisted of fruit sampling in orchards with different forms of
agriculture and in its subsequent analysis in laboratory, with the objective of determining the
possible quality differences among citrus coming from organic farming way and conventional
farming.
After the analyses it was verified that the medium weight and the dimensions of the fruit were
superior in the fruits coming from conventional orchards. In this form of agriculture it was
recorded the largest juice percentage, the smallest concentration of acidity, the most intense
coloration, the largest tenor of soluble solids and the higher maturation index. By opposite, the
smallest thickness of the fruits peel, the largest concentrations of analyzed acids, with exception
of the oxalic acid, and the highest concentrations of sugars (fructose, glucose and sucrose) were
recorded in the biological agriculture fruits.
