摘要
以哈密瓜西州蜜17号为实验材料,在低温(6~8℃,RH80%~85%)环境下对甜瓜分别采取不同臭氧浓度(2.14、4.28、6.42 mg/cm^3)和不同间隔时间(12、24、48 h)处理,每次通入臭氧后进行密闭处理40 min,研究不同臭氧处理对甜瓜在整个贮藏保鲜42 d中的变化。结果表明:臭氧处理能够有效延缓相对电导率的上升,可滴定酸和抗坏血酸平均每天仅下降1.1%、1.2%,臭氧对其下降起到了明显的抑制作用,同时降低了23%的呼吸速率,推迟7 d出现呼吸高峰,腐烂指数仅为对照组的6.8%。臭氧浓度4.28 mg/cm^3、处理间隔时间24 h可以最好的保持甜瓜果实采后品质,延长了低温贮藏时间。本文为甜瓜采后贮运保鲜提供了可行的方法。
In this paper," Xizhoumi No.17" was used as material, and the experiment was carried out at 6-8℃ with RH80% 85% .The ozone concentration was 2.14,4.28,6.42 mg/cm3 and the interval was 12,24,48 h and for closed handling 40 min. The effects of different ozone treatments on the physiological of melon during the whole 42 d storage period was studied.The results showed that ozone treatment can delay the increase of conductivity,inhibit the decline of TA and Vc whose average daily decline only of 1.1 and l.2% respectictively. Ozone treatment also reduced the respiration rate by 23 %, postphoned respiration peak by 7 days, and its decay index was only 6.8% of the control.Ozone concentration of 4.28 mg/cm^3 and the interval of 24 h can best guarantee the quality and extend the low temperature storage time of melon fruit, which provides a feasible method for the storage, transportation and nreservation of melon.
