硫化氢在采后果蔬贮藏保鲜中的应用

硫化氢作为植物体内的一种气体信号分子,可以调节植物的代谢,影响采后果蔬贮藏期间的生理活动及营养品质。硫化氢能够参与调控果蔬的成熟衰老,激发防御基因的表达,诱导植物的病伤害反应、抗性的形成,延缓其采后衰老,延长货架寿命。本文综述了国内外关于硫化氢在采后果蔬贮藏保鲜中的研究进展,从采后生理学角度出发,对硫化氢在果蔬的代谢过程中的作用进行阐述,主要对感官品质、能量代谢、呼吸强度、乙烯生成、褐变和病害6个方面进行探讨,以期为今后硫化氢在果蔬保鲜上的研究及应用提供参考依据。

Application of Hydrogen Sulfide in Storage and Preservation of Postharvest Fruits and Vegetables

Hydrogen sulfide, as a gas signal molecule in plants, regulates the metabolism of plants and affects the physiological activities and nutritional quality of postharvest fruits and vegetables during storage. Hydrogen sulfide participates in the regulation of ripening and senescence of fruits and vegetables, stimulates the expression of defense genes, induces the formation of disease damage response and resistance of plants, delays their postharvest senescence and prolongs shelf life. This paper summarized the research progress of hydrogen sulfide in the storage and preservation of postharvest fruits and vegetables at home and abroad. From the perspective of postharvest physiology, the role of hydrogen sulfide was expounded in the metabolism of fruits and vegetables. six aspects of sensory quality, energy metabolism, respiratory intensity, ethylene generation, browning and disease were discussesed in order to study the application of hydrogen sulfide in the preservation of fruits and vegetables in the future for reference.
