Abstract

Quality characteristics of radish treated with red clay-processed materials (RCPM) were investigated. Two different types of treatments using RCPM including a control were farm-raised in identical environments. General components, texture, nutrients, and antioxidant activities were performed. For general components analysis, total amounts of crude fat and ash were higher in radish treated with RCPM than in control. RCPM-treated radish showed higher contents of minerals (P, Mg, K, Zn, Mn, and Na) and vitamins (vitamin C, thiamin, and riboflavin) than those of control. RCPM-treated radish exhibited higher DPPH radical scavenging activities and total polyphenol contents than those of control, indicating higher antioxidant activities of radish raised by RCPM. In the textural analysis following refrigeration for 4 weeks, RCPM-treated samples showed a more stable texture and higher hardness values than those of control. Therefore, these results indicate that RCPM can be used to produce high-value radish of premium quality.

본 연구는 무의 재배 시 가공황토 처리 여부에 따른 무 시료의 품질 특성을 비교하고자 무 시료를 동일한 조건으로 재배하여 일반성분, 물성, 영양소, 기능적 특성을 분석하였다. 조회분과 조지방 함량에서 실험구1, 2가 대조구 대비 더 높은 함량을 나타내었다. 또한 분석된 모든 무기성분 및 비타민 함량에서 실험구1, 2가 대조구 대비 유의적으로 높은 함량을 나타내었다. 실험구1, 2에서 비타민 C의 함량이 대조구보다 높게 나타남과 동시에 항산화 활성 또한 유의적으로 높은 것을 확인할 수 있었다. 또한 견고성 측정 결과 대조구에 비하여 황토처리 된 실험구1, 2의 경우 저장기간 동안 견고성 감소율이 낮아 저장기간 동안 조직감의 유지가 가능한 것으로 나타났다. 따라서 무 재배 시 친환경 가공황토소재를 화학비료 대신 적용하여 재배할 경우 무의 저장성이 강화된 고품질의 무 생산이 가능해지고 기능성이 부가된 다양한 무를 활용한 고부가가치 제품이 가능해져 국내 무 시장의 활성을 촉진시킬 수 있다고 판단된다.
