|Resumo:||In this study was evaluated the eﬀect of production mode (organic versus conventional) on some physical-chemical properties of three blueberry cultivars (Duke, Bluecrop, Ozarkblue). The properties evaluated were caliber, moisture content, total soluble solids, acidity, color and texture. The eﬀect of storage on these properties was also evaluated. For this, samples were analyzed at harvest and after 7 and 14 days of storage. This work showed that Duke blueberries had a higher diameter and a more intense coloration. It was also found that the Duke blueberries presented a harder and more elastic texture, when compared with the other cultivars at study.Cultivar Ozarkblue from conventional production mode showed at harvest the higher sugar content and for cv. Ozarkblue a trend for decreasing acidity along storage time, was further noticed. In respect to the production mode it was detected that the blueberries produced in organic farming were less acid and less sweet, but had a more intense blue color and were less elastic when compared with blueberries produced in conventional mode. The blueberry storage temperature (cold or at room temperature) did not meaningfully inﬂuence the chemical properties of blueberry, but inﬂuenced the physical properties, namely colour and texture.|
