Abstract

The invention provides a method for extracting tobacco surface terpene and sugar ester compounds by utilizing tobacco land waste and application thereof. Fresh and untreated tobacco land production waste is used as a raw material, absolute ethyl alcohol is used as a solvent to extract an aroma component on the surface of the raw material, and a tobacco surface aroma component tincture containing terpene and sugar ester compounds is obtained. The terpene can be used for perfuming tobacco products. According to the extracting method, the raw material does not need to be pretreated, extraction isdirection performed by adopting the fresh raw material and the ethyl alcohol, the operation is simple, the cost is low, the raw material is not smashed, and the obtained extract contains few impurities. The remaining after extraction can be continuously used for extraction of beneficial active ingredients such as tobacco nicotine, chlorogenic acid and solanesol and can be also used for producingorganic fertilizers having insecticidal activity and containing nicotine, and staged high-value-added utilization of tobacco land waste can be achieved.

Description

technical field [0001] The invention relates to the utilization method of field wastes such as tobacco fireworks, axillary buds and top leaves, in particular to a method for extracting diterpenes and sugar ester compounds on the surface of tobacco by using field tobacco wastes and its application in cigarette flavoring. Background technique [0002] my country is a big tobacco producing country, and the tobacco industry has a unique position in the national economy. At present, my country's tobacco planting area is more than 12 million mu, and the total output of tobacco leaves accounts for about 41.5% of the world's total output. However, in the field production of tobacco, fireworks, axillary buds, lower foot leaves, and upper top leaves are all treated as waste, resulting in a large waste of resources. [0003] In order to make full use of tobacco field waste resources, tobacco scientific research institutes and enterprises have carried out technical research on extracti...
