Abstract:

【Objective】 To study the effect of modified atmosphere packaging on the preservation of fresh fruits of Lycium barbarum under low temperature conditions, and screen the appropriate gas parameters in the hope of providing a theoretical reference for the storage and transportation of fresh fruits of Lycium barbarum in Xinjiang production.【Methods】 Fresh fruits of Xinjiang Jinghe wolfberry were used as test material, and three different gas permeable films were used to pack the fruits, that was low (4.0%-5.2%CO2), medium (3.4%-4.0% CO2), and high (2.2%-3.3% CO2), under the storage environment of (0±1) °C.The fruit decay rate, weight loss rate, textural characteristics, fruit surface color, different respiratory pathway rates, soluble solids, ascorbic acid, and malondialdehyde and other fruit qualities were measured regularly during the storage.Afterwards, the effect of different gas-conditioned packaging treatments on the fresh fruit preservation effect of Lycium barbarum were analyzed.【Results】 Compared with CK, the treatment of medium permeable packaging (3.4%-4.0% CO2) significantly inhibited the decay rate and weight loss rate of wolfberry fresh fruit, maintain better texture characteristics and color of wolfberry fresh fruit, reduced the total respiration rate, delayed the decrease of soluble solids and ascorbic acid content and the increased of malondialdehyde content, and effectively maintain the quality of wolfberry fresh fruit in Jinghe.【Conclusion】 Medium breathable packaging (3.4%-4.0% CO2) fresh fruit of Lycium barbarum L.in Jinghe has the best preservation effect, so that the fruit can still maintain good commercial value after 30 days of storage.

摘要:

【目的】 研究不同气调包装处理在低温条件下对枸杞鲜果保鲜效果的影响,筛选适宜的气体参数,为生产中枸杞鲜果的贮运保鲜技术提供理论参考。【方法】 以新疆精河枸杞鲜果为试材,在(0±1)℃的贮藏环境下,采用低(4.0%~5.2%CO2)、中(3.4%~4.0%CO2)、高(2.2%~3.3%CO2)3种不同气体透过性膜包装果实,定期测定贮藏期间果实腐烂率、失重率、质构特性、果实表面色泽、不同呼吸途径速率、可溶性固形物含量、抗坏血酸以及丙二醛等果实品质,分析不同气调包装处理对枸杞鲜果保鲜效果的影响。【结果】 与CK对照相比,中透气包装(3.4%~4.0%CO2)处理可显著抑制枸杞鲜果腐烂率和失重率,维持枸杞鲜果较优的质构特性和色泽,降低总呼吸速率,延缓可溶性固形物、抗坏血酸含量的下降和增加丙二醛含量,有效维持精河枸杞鲜果品质。【结论】 中透气包装(3.4%~4.0%CO2)精河枸杞鲜果的保鲜效果最佳,使果实在经过30 d的贮藏期后仍能保持较好的商业价值。
