而實驗結果顯示，氣變包裝組果實到貨可售率(92±2.8%)明顯優於現行包裝組(60.7±13.1%)。回溫展售3天，氣變包裝組可售率(66.4±13.7%)仍高於慣行包裝組(9.2±1.9%)。園藝系解釋，氣變包裝能夠減緩「珍珠拔番石榴」病害、質地軟化、果皮轉黃的情況，且效果較現行包裝更優；經貯運回溫後，氣變包裝組果肉硬度(166±10 N cm-2)、果皮色相角(110±1°)也比現行包裝組(140±10 N cm-2、106±1°)更能維持較佳品質，且對風味無不良影響。
Department of Horticulture and Landscape Architecture developed a novel “modified atmosphere package” technology to maintain the quality of guavas. The figure shows the appearance of “Jen Ju Bar” guavas after 4 weeks of storage followed by 3 days at 30°C using a conventional package and the modified atmosphere package. The fruit arrival availability ratio of the modified atmosphere package (92±2.8%) was higher than that of the conventional package (60.7±13.1%). After an additional 4 weeks of storage followed by 3 days, the fruit availability ratio of modified atmosphere package (66.4±13.7%) was still higher than that of conventional package (9.2±1.9%). The results were attributed to the fact that the modified atmosphere package could alleviate the disease of the "Jen Ju Bar” guava and soften the texture. Thus, the modified atmosphere package is better than the current conventional package. After storage and transportation back to the room temperature, guavas in the modified atmosphere package group had better hardness (166±10 N cm-2) and hue angle (110±1°) than the current conventional package group (140±10 N cm-2, 106±1°).
