무 싹채소 탄산 가스 처리에 따른 생육과 수확후 품질 특성 비교

Abstract

As sprout vegetables of interest growing, its maintaining the quality of the technology was needed to solve the problem of increasing growth and maintain quality after harvest. This experiment proved that the quality of radish sprout vegetable was affected by CO2 treatment during cultivation. Thus, the effect of CO2 treatment during cultivation on postharvest quality of radish sprout vegetable was investigated in terms of the quality changes in weight loss, gas partial pressure, SPAD, hue angle external appearance during storage at polypropylene film (thickness 30 μm) at 10oC. CO2 treatment used the way to gas with 700 ppm or carbonated water with 700 ppm and 1,400 ppm. The study revealed that growths on CO2 treated plant were more than those of non-treatment on stem length. After harvesting, the CO2 treated plant and control growing little different characteristics on fresh weight, plant length and so on. However, there were no differences between the CO2 treated plant and control on the Fv/Fm and SOD (superoxide dismutase). In gas partial pressure, the O2 consumption and CO2 accumulation of the CO2 treated plant tended to be more than that of non-treated plant. This study also checked that after packaging, the effects of CO2 treatment during cultivation on the quality of radish sprout vegetable was not significant. However, there were tended to CO2 treatments were lower value compared to control on SPAD, hue angle and general appearance. CO2 treatments of radish sprouting vegetable before harvest were improve growth of stem length, but ones were not improving the maintain of quality on radish sprout vegetable during shelf-life period. The results indicated that CO2 treatment only affected stem elongation until radish sprout vegetable its growth.
