Abstract

As consumers are aware of their health and are more conscious of environmental conditions, there is an increasing demand for agri-foods obtained from organic agricultural practices. The present study aimed to investigate the physicochemical quality characteristics of blueberries. The weight, length, moisture contents, color (Hunter L, a, b), soluble solids contents, pH, and acidity were measured for their quality characteristics. In addition, ABTS radical scavenging activity was analyzed for antioxidant activities of organically and conventionally grown blueberries. Organically grown blueberries showed a greater weight, soluble solid contents, and pH than conventionally grown ones. Especially, organically grown blueberries showed significantly (p<0.05) higher weight and pH. Moisture contents of organically and conventionally grown blueberries were similar. L and b values of organically grown blueberries were higher than those of conventionally grown blueberries. ABTS radical scavenging activities of organically grown blueberries (36.4%) were higher than those of conventionally grown ones (36.4%), but the difference was not significant. Further studies are recommended to evaluate other differences between organically and conventionally grown blueberries.
