The effect of packaging and storage methods in enhancing the shelf life and improving the postharvest quality of the Korean head cabbage (Brassica rapa) used for wrapping vegetables was studied at 10oC. The wrapping cabbage was packed using four types of packaging and storage materials: (A) Perforated PP film; (B) Non-perforated PP film; (C) PVC film for wrapping; and (D) non-packaged as control. The quality parameters, such as fresh appearance, weight loss, hue angle, moisture content, hardness, and SSC of wrapping cabbage were investigated. The weight loss of wrapping cabbage showed a significant difference between the one packaged with film and the non-packaged as control. The general appearance of Korean cabbage stored at 10oC was not significantly affected by the packaging treatments. However, Korean head cabbage packaged with perforated film tend to show a better external appearance compared with those exposed to the other packaging during three weeks of storage at 10oC. The inside appearance, hue angle, moisture content, hardness, and SSC, gradually decreased during the storage period. No remarkable change in the measured items were observed in Korean cabbage packaging methods. In this experiment, the Korean cabbage packaged inside a PP film with holes, and stored at 10oC temperature had the most desirable outcome of extending the head cabbage’s shelf life and appearance quality. Results suggest that perforated packaging treatment combined with low storage temperature could be an effective method in prolonging the shelf life of Korean cabbage for wrapping vegetable.
