유기 및 일반재배에 따른 풋고추의 이화학적 품질특성 및 항산화활성을 비교하고자 무게, 길이, 수분함량, 표면색도, 경도, DPPH 및 ABTS radical 소거능, 총페놀함량 등을 분석하였다. 무게, 길이의 경우 전반적으로 유기농 풋고추에서 무게가 적고, 길이가 짧았으며 수분함량의 경우 유기 및 일반재배 간 비슷한 값을 나타내었다. 표면색에 있어서 유기농 풋고추의 L과 b값이 높았고, a값은 일반재배 풋고추의 값이 높았으며 재배조건에 따른 L, a, b값의 유의적인 차이를 보였다. 항산화활성의 경우 DPPH radical 소거능은 유기농 풋고추가, ABTS radical 소거능은 일반재배 풋고추가 높은 활성을 보였다. 총 페놀 함량은 유기농 풋고추 값이 높았으나 유의적 차이를 보이지 않았다. 본 연구에서는 무게, 길이 등의 외적 품질에 대해서 일반재배 풋고추의 값이 높았고, 항산화활성에 대해서는 전반적으로 유기농 풋고추에서 다소 높은 활성을 보였으나 유기 및 일반재배에 따른 내외적 품질비교를 위해서 더 많은 분석이 추가로 진행되어야 할 필요가 있다고 사료된다.
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.
