摘　　要：探究微环境气调(mMAP)结合相温贮藏对百合采后贮藏品质的影响。以兰州百合为试材,将百合装入微环境气调箱中,分别置于冷库和相温库存放。设计为3个处理,分别为CK(无气调)+相温、mMAP+冷藏、mMAP+相温,每15 d记录箱体内气体成分含量变化,检测百合硬度、感官品质、营养物质含量、生理指标及挥发性物质。结果表明,百合在O_(2)含量9.4%~15.6%,CO_(2)含量4.7%~10.8%的贮藏环境内可有效控制腐烂程度,维持硬度在较高水平。与mMAP+冷藏相比,mMAP+相温中CO_(2)含量较高,O_(2)含量较低,抑制了贮藏后期营养物质的流失,降低了呼吸强度和乙烯生成速率;抑制了醇类、酯类及烯烃类物质的挥发,促进了十二醛、己烯醛、(Z)-庚烯醛、(E)-2-辛烯醛等百合特征性醛类香气物质的释放。综合比较,微环境气调结合相温贮藏下百合的贮藏品质最佳。The effect of micro-environment modified atmosphere package combined with phase temperature storage on the physiological quality of lilium during postharvest storage was studied.Lanzhou lily as experimental materials,the lily to detail the environment air box temperature were placed in the refrigerator and phase in the inventory,designing for the three treatment,which were phase temperature without modified atmosphere and mMAP combined with cold storage and mMAP combined with phase temperature,recording every 15 d the casing gas component content changes,lily hardness,sensory quality,nutrient content and physiological indicators and volatile substances.The results showed that the rotting rate of lily in the storage environment with O_(2) content of 9.4%-15.6%and CO_(2) content of 4.7%-10.8%could be effectively controlled and the hardness could be maintained at a high level.Compared with mMAP combined with cold storage,the concentration of CO_(2) in the mMAP combined with phase temperature is higher,inhibited the late storage nutrient loss and reduced the rate of respiration and ethylene formation,restrained the alcohols,esters and olefin volatile substances,promoted the twelve aldehyde and hexene aldehyde,(Z)-heptene aldehyde,(E)-2-octene aldehyde characteristic such as lily aldehyde aroma substances released.The results showed that the storage quality of lily is the best under the condition of micro-environment modified atmosphere package combined with phase temperature storage.
