臭氧处理对新疆厚皮甜瓜贮藏品质和生理特性的影响
Effects of Ozone Treatment on Storage Quality and Physiological Characteristics of Xinjiang Thick-Skinned Melon
摘要
Abstract
Xinjiang thick-skinned melon is a type of fruit which is extraordinarily favored by people, but it does not withstand storage or transportation. This study was concerned with the effects of 4 different storage conditions i.e., a) treatment with ozone at 5 × 10-6 m3/m3(on an air basis) for 5 h every seven days during storage at −1–0℃; b)2 × 10-6 m3/m3 ozone for 30 min every day during storage at 5–6℃; c) 4 × 10-6 m3/m3 ozone for 30 min every day during storage at 5–6℃; and d)2%–5% O2 + 2%–4% CO2 during storage 5–6℃, on the storage quality and physiological properties of Xinjiang thick-skinned melon. Untreated fruits were used as control. With this aim, we determined respiration intensity, ethylene production rate, soluble solids content, titratable acid content, pH, fruit hardness, reducing sugar content and peroxidase (POD) activity of melon under these conditions were determined every 15 days of storage, and we also statistically analyzed decay index and chilling injury index of melon fruits in all treatment groups after 68-day storage. The experiment results suggested that low-temperature storage (−1–0℃) resulted in the minimum decay index, but caused chilling injury (the chilling injury index after 68-day storage was 39%). The second treatment better maintained the quality of melon fruit than the control group, and the third treatment provided the best maintenance of fruit quality as indicated by delaying the occurrence of the respiratory peak, decreasing respiration intensity, minimizing ethylene production rate, and increasing reducing sugar content, fruit lfesh ifrmness and POD activity, consequently achieving a decay index of only 0.318 after storage for 68 days. The highest titratable acid content was found in the fourth treatment, showing a highly signiifcant difference as compared with the other three treatment groups (P < 0.01). The control group was the least effective at preserving the quality of melon fruit.关键词
