Method for preparing tobacco extract and application thereof

Abstract

The invention relates to a method for preparing tobacco extract and application thereof. The method for preparing the tobacco extract uses tobacco as a raw material to prepare the tobacco extract through the steps of enzymolysis, ultrasonic extraction, filtration, chromatography column separation and concentration under reduced pressure; and the tobacco extract is dissolved by 80 percent ethanol and sprayed into tobacco shreds by adopting an atomizing mode. The method using enzymolysis technology and ultrasonic extraction and combining the chromatography separation has the advantages of low extraction temperature, short time, little using amount of a solvent, full extraction and high raw material utilization rate; because the extraction temperature is low, the damage to thermal-sensitive fragrant substances is reduced, fragrant components of the tobacco self is furthest kept, and simultaneously the substances influencing the taste and mouthfeel are removed; and the method is simple, the equipment is easy to operate, and no pollution is produced.

Description

technical field [0001] The invention belongs to the technical field of phytochemistry, and in particular relates to a preparation method and application of a tobacco extract. Background technique [0002] Smoking and health issues have attracted worldwide attention, and reducing the release of harmful components in cigarette smoke is an unshirkable responsibility of the tobacco industry. With the gradual increase of people's attention to smoking and health issues, the tobacco industry has implemented tar reduction and harm reduction projects in recent years to continuously adapt to the requirements of society. With the continuous reduction of tar content in cigarettes, the aroma components in tobacco are also The corresponding reduction requires compensating the aroma of low-tar cigarettes. Obviously, extracting spices from tobacco is an important way to effectively compensate the aroma of low-tar cigarettes. At present, one type of tobacco extract extraction method commonl...

Problems solved by technology

At present, one type of tobacco extract extraction method commonly used in my country's tobacco industry is to obtain products by ordinary solvent extraction, and the other is to use steam distillation and a small amount of supercritical carbon dioxide extraction to obtain products. Although the products prepared by these methods can be better However, due to the lack of selective separation of the extracted components, it contains some substances that are not suitable for cigarette smoking. While increasing the smoke, it also causes side effects such as discomfort in smoking, increased roughness and dryness. leading to a decline in the quality of cigarettes
