Evaluation of quality characteristics of Brassica campetris L. Treated with environmentally-friendly red clay-processed materials

Abstract

Quality characteristics of Korean cabbage treated with red clay-processed materials (RCPM) were evaluated. Two different types of RCPM treatments including a control were applied for the cultivation of cabbage. General components, nutrients, antioxidant activities, textures, and sensory evaluation were assessed. For the nutrition components analysis, RCPM-treated cabbage showed higher contents of potassium and riboflavin along with lower content of sodium compared to the control. RCPM-treated cabbage exhibited higher total polyphenol contents than those of the control, indicating higher antioxidant activities. For the textural analysis under refrigeration over 4 weeks, RCPM-treated samples showed more stable textures based on higher hardness values than the control and RC. Results of this study indicate that RCPM would be of benefit to produce high-value added cabbage of premium quality. © 2015, J Korean Soc Food Sci Nutr. All rights reserved.
