甘藍簡易人工大氣貯藏試驗

Abstract

利用PVC(poly vinyl chlolide)塑膠膜，以高週波機密封製成之簡易人工大氣貯藏室，配以乙烯及二氧化碳過濾吸取裝置，因氣密性不佳，氧氣在13~18%之間，二氧化碳3~6%之間，無法達到理想之大氣組成，但甘藍經三個月之貯藏其可售率可達68%。 Cabbages (Brassica oleracer, var. capitata, cultivar 'Chu-chiuo') were stored in a sealed polyvinylchloride (PVC) tent (0.1m/m in thickness, 8m^3 in capacity) and polyethylene (PE) bags (0.03 m/m in thickness, 0.9M×1.5M in size) for 3 months. The ethylene and carbon dioxide in the tent were reduced by potassium permangnate and fresh lime. However, the control of O2 concentration inside the tent was not quite successful because of the leakage of the tent. The concentrations of O2 and CO2 were 13-18% and 3-6% respectively.
