Method for preparing tobacco extract by utilizing waste and inferior tobacco leaves

Abstract

The invention provides a method for preparing tobacco extract by utilizing waste and inferior tobacco leaves. The tobacco extract is prepared through the following steps: mixing tobacco powder, tobacco leaf fragments and tobacco stems in a cigarette manufacturing department and adding the mixture into an ethanol solution for extracting; decompressing and concentrating; then adding pure water and glucose in sequence; after uniformly stirring, adding cellulase and subtilisin in sequence to carry out enzymolysis; then adding the mixture subject to enzymolysis into the ethanol solution and standing; filtering with a ceramic film; and decompressing and concentrating and then carrying out molecular distillation and separation. According to the method, efficient, rapid, energy-saving and environment-friendly effects are achieved; prepared molecular distillate has a real aroma and the taste is remarkably improved; the product is used as essence and spice for cigarettes so that the aroma of the cigarettes can be obviously improved; and meanwhile, the product also has soft, fine and smooth smoke and has the effects of improving the sweet feeling of the oral cavity and improving the smoke volatility.

Description

technical field [0001] The invention relates to a method for preparing tobacco extract, in particular to a method for preparing tobacco extract by using waste tobacco leaves. technical background [0002] Tobacco, a plant of the genus Nicotiana in the Solanaceae family, is produced in South America. It was introduced earlier in my country and has a large output. At present, my country's tobacco planting area and tobacco leaf output both rank first in the world, and related income related to the tobacco industry plays an important role in my country's national economic development. In the process of tobacco planting, harvesting, transportation, storage and tobacco leaf processing, a large amount of waste and inferior tobacco leaves are produced, accounting for about 25%-30% of the total output of tobacco leaves. Inappropriate, not only a waste of resources, but also easy to pollute the environment. From the current literature reports, it can be seen that experts and scholar...

Problems solved by technology

Although the above-mentioned method can also prepare tobacco extract, there are many macromolecular proteins, macromolecular fibers and macromolecular polysaccharides in the prepared tobacco extract, these materials are not suitable for volatilization, and remain in the extract, which affects the volatility of the extract spices. Reduce the softness and delicateness of the aroma of spices, resulting in certain deficiencies in the aroma fidelity and cigarette effect evaluation of the prepared tobacco extract

Moreover, most of the above methods use waste tobacco powder or tobacco stems alone as raw materials, and do not optimize the ratio of cigarette production waste such as tobacco powder, tobacco leaf fragments, and tobacco stems, which affects the recycling efficiency of cigarette production waste.
