Beschreibung
Zusammenfassung:	The invention relates to the field of food preservation, and particularly discloses a preparation method of a gamma-cyclodextrin metal organic framework, which comprises the following steps: dissolving gamma-cyclodextrin and potassium hydroxide in water, then filtering, adding methanol into filter residues for crystallization, collecting crystals, washing and drying to obtain the gamma-cyclodextrin metal organic framework. The gamma-cyclodextrin metal organic framework prepared by the method disclosed by the invention can be directly eaten, is harmless to a human body, does not cause pollution to food when being used for controlled atmosphere storage of the food, and has good ethylene absorption capacity. 本发明涉及食品保鲜领域，具体公开了γ-环糊精金属有机框架的制备方法，包括以下步骤：将γ-环糊精、氢氧化钾溶于水中，然后过滤，将滤渣中加入甲醇进行结晶，收集晶体并洗涤、干燥，即得所述γ-环糊精金属有机框架。由本发明方法制得的γ-环糊精金属有机框架可以直接食用，对人体无害，当用于食品气调储藏时，不会对食品造成污染，且具有良好的乙烯吸收能力。
