초록

An experiment was conducted to find out the effect of brushing treatment during cultivation on the postharvest quality of the baby leaf vegetable, specifically tah tasai Chinese cabbage (Brassica campestris var. narinosa). The effect of mechanical brushing during cultivation on the postharvest quality was determined in terms of the quality changes in weight loss, gas partial pressure, leaf color, and appearance during storage using a 30-㎛-thick polypropylene film at 16℃. The brushing treatment included brushing with A4 paper back and forth 50 times a day. The study revealed that the growths on the brushing-treated plant group were less than those on the control group. The structure of the leaf tissue of the brushing-treated plant also tended to be less compact than that of the non-treated plant. The brushing treatment resulted in less growth and denser plant tissues as well as in differences in the gas O2 consumption and CO2 accumulation after packaging. For the gas partial pressure, the O2 consumption and CO2 accumulation of the brushing-treated plant tended to be less than those of the non-treated plant. There were no differences, however, between the brushing-treated plant and control groups in the SPAD value and appearance. The study results also suggested that after packaging, the effects of the brushing treatment during cultivation on the quality of the tah tasai Chinese cabbage baby leaf vegetable was not significant. As such, it is recommended that effective post-harvest methods of improving the product quality of the baby leaf vegetable be further investigated.
