Abstract
As consumers are aware of their health and are more conscious of environmental conditions, there is an increasing demand for organic agri-foods. The present study aims to investigate the physicochemical quality characteristics and antioxidant activity of organic green peppers. The weight, length, moisture content, color (Hunter L, a, b) and hardness were measured for the quality characteristics. In addition, the DPPH, ABTS radical scavenging activities and total phenolic contents were analyzed for the comparison of antioxidant activities between organically and conventionally grown green peppers. The weight and length of the organically grown green peppers were lower than those of the conventionally grown ones. The moisture content of the organically and conventionally grown green peppers was similar. The L and b values of the organically grown green peppers were higher than those of the conventionally grown ones. The DPPH radical scavenging activity of the organically grown green peppers (62.86%) was higher than that of the conventionally grown ones (51.06%). The total phenolic content of the organically grown green peppers was higher than that of the conventionally grown ones, however, there was no significant differences between organically and conventionally grown green peppers (p<0.05). Further studies would be recommended for the evaluation of other characteristics such as flavor, taste, and bioactivity compounds between organically and conventionally grown green peppers.
