Effects of Different Packagings on the Storability of Longan (Dimocarpus longan Lour.) Fruits
摘要
Abstract
The effects of environmental factors within different packagings on the storability of longan fruits (Dimocarpus longan Lour.cv.Shixia) during storage at (25±1)℃ and (4±1)℃ respectively were studied.The treatments including 0.02 mm BOPP bag (Biaxial oriented polypropylene film,marked as BOPP),0.025 mm Polyethylene bag (marked as PE),0.025 mm EVA bag (Ethylene-co-vinyl acetate,marked as EVA) and 0.025 mm ZSMA bag (Zhongshan modified atmosphere packaging bag,marked as ZSMA),and plastic pallet + single layer of 0.010 mm PE (marked as PF1) as the normal storage temperature check and 0.025 mm PE as the the low storage temperature check were used.The results showed that the orders of pericarp browning index,aril breakdown index and mass loss rate at (25±1)℃ storage were PF1 ＞EVA＞PE＞BOPP≈ZSMA,PF1 ＞PE＞BOPP＞ZSMA ≈EVA and EVA＞PF1＞PE＞ZSMA ≈BOPP respectively.Whereas,during storage at (4±1)℃,the orders of them were EVA＞BOPP＞ZSMA＞PE,PE＞ZSMA＞EVA＞BOPP and EVA＞PE≈ZSMA≈BOPP respectively.The volume fraction of CO2 (V/V) in the same bag at (4±1)℃ was significantly lower than that at (25±1)℃,but the volume fraction of O2 (V/V) was higher.Among the 4 treatments,the order of volume fraction of CO2 was BOPP＞ZSMA＞PE＞EVA,while the volume fraction of O2 was reversed;and the moisture permeability of EVA was much more higher than that of other packagings.The RH was the most important factor for pericarp browning.In addition,the fruit storability in BOPP and PE bags showed partly opposite results due to temperature variation,the injury threshold value of longan fruit to CO2 varied with storage temperature.The ZSMA bags showed the best combination storability.关键词
