高浓度CO2气调对浆果生理及超微结构影响的研究进展

目的介绍高浓度CO_2对浆果采后超微结构和生理代谢影响的研究进展,为浆果保鲜提供新的思路和依据。方法从高浓度CO_2气调贮藏在浆果保鲜中的应用和高浓度CO_2气调贮藏处理对浆果生理生化变化的影响入手,总结国内外高浓度CO_2贮藏浆果、类浆果及其他水果的相关文献。结果通过总结高浓度CO_2对浆果采后超微结构和生理代谢影响的内在机制和共性科学问题,解析了浆果类果实可以忍耐高浓度CO_2的内在原因,归纳出了高浓度CO_2处理延缓浆果生理代谢和衰老进程的生理机制。结论作为一种通过物理手段可有效保持浆果品质的贮藏方法,高浓度CO_2气调贮藏保鲜技术具有能延迟浆果后熟衰老,避免低温冷害和其他生理性病害的发生,有效延长浆果货架期等特点。高浓度CO_2气调贮藏及包装的综合运用将会为浆果贮运及其物流配送带来新的生机和希望。

Research Progress of Effects of High-concentration CO2 Modified Atmosphere on the Physiological Metabolism and Ultrastructure of Berry

The work aims to introduce the research progress of effects of high-concentration CO2 on the postharvest ultrastructure and physiological metabolism of berry and provide new idea and basis for its preservation. Starting from the application of modified atmosphere storage of high-concentration CO2 in the preservation of berry and the effects of treatment by modified atmosphere storage of high-concentration CO2 on the physiological and biochemical change of berry, the relevant literature on the berry, berry-like fruit and other fruit stored in high-concentration CO2 at home and abroad was summarized. By summarizing the internal mechanism and generic scientific problems of the effects of high-concentration CO2 on the postharvest ultrastructure and physiological metabolism of the berry, the underlying cause for the resistance of berry-like fruit against the high-concentration CO2 was analyzed, and the physiological mechanism of high-concentration CO2 treatment used to delay the physiological metabolism and aging process of the berry was concluded. As a kind of storage method that could effectively maintain the quality of berries through the physical means, the preservation technology of high CO2 modified atmosphere storage is characterized by the abilities to inhibit after-ripening and senescence, avoid chilling damage and other physiological disorders, and effectively prolong the shelf life of berries, etc. The comprehensive application of high concentration CO2 modified atmosphere storage and package will bring new vitality and hope for the storage and transportation of berry and its logistics distribution.
