Abstract: The juice processing quality and antioxidation activity of different blueberry cultivars in Hubei province were evaluated in this study to profoundly understand the breeding, postharvest storage and processing of blueberry. Fresh berries of seven blueberry cultivars, “Premier”, “Briggita”, “Legacy”, “ONeal”, “Misty”, “Northland”, and “Bluerain” were evaluated. The chemical composition and sensory properties were detected and the antioxidant and antioxidation activity were correlated by Pearson correlation. The results showed that different blueberry cultivars presented different processing quality. “Premier” was big berries and total soluble solids contents were high. “Misty”, “O'Neal” and “Legacy” were middle-size berry and contained a balanced sweet-sourness which made them more suitable for fresh marketing. “Brigitta” berries were the biggest but with low pH. This character makes them more ideal for juice processing. “Northland” and “Bluerain” were small berries with high pectin content. The antioxidants of “Premier” blueberry were the highest compared with other cultivars and “Brigitta” was the lowest. Furthermore, the antioxidant activity of blueberry was positively correlated with total anthocyanin, total phenolic and total flavonoid content in berries.
