RESUMO

The objectives of this study were 1) to correlate the visual parameters with the physical-chemical parameters to establish exact measurements for the quality of fresh fruit oranges (cultivar Pêra), and 2) to establish standards by utilizing scientific methods to serve as a basis for quality control measurements that can be simply applied by the farmers with the purpose of assuring product quality, thus increasing the value of the oranges, the revenue of the farmers and improving the sector. Orange fruits were obtained from the regions of Barretos and Limeira, SP, Brazil, and analyzed in the Agro industry, Food and Nutrition Department of ESALQ/USP and at CENA/USP. Physical aspects of the fruits (firmness, color, density, diameter and length), physical-chemical properties pH, soluble solids (SST), titrateable total acidity (ATT), ratio, total and reducing sugars, total phenolic compounds, pectic substances, chlorophyll, carotenoids, and vitamin C) and visual traits according to the Descriptive Quantitative Analysis Index (DQA) were analyzed.
