| Abstract:In order to develop new nicotine loaded materials, this article studied the use of β- Preparation of a novel Metal Organic Framework (MOF) material using cyclodextrin and sodium hydroxide as raw materials, and in situ modification of bacterial cellulose (BC) using this material to obtain MOF@BC Composite materials. A systematic analysis was conducted on the composite materials from the aspects of microstructure, nicotine release performance, and thermal decomposition aroma products using scanning electron microscopy, X-ray diffraction, thermogravimetric experiments, thermal decomposition, and thermal desorption. The scanning electron microscopy, infrared spectroscopy, and X-ray diffraction results of MOFs indicate that the new method reported in this article can be used to prepare novel MOF materials loaded with nicotine, which contain abundant pore sizes. MOF@BC The scanning electron microscopy results show that, MOF@BC The embedding of MOF material in the fiber grid indicates that MOF material has successfully modified BC to form a composite material. Thermogravimetric studies have shown that MOF@BC The maximum weight loss stage temperature of the composite material was delayed by 44℃ compared to the blank BC, and the nicotine release increased by 5.8% with a time delay of 1.055 minutes. It has a stronger loading capacity for nicotine than the blank BC and has a certain degree of sustained release. MOF@BC The thermal decomposition of composite materials releases up to 20 types of aroma components, which is beneficial for improving the sensory quality of food intake. |
