친환경 황토 가공 신소재 적용 재배법에 의한 무의 품질 특성

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.
