Problems solved by technology

Recently, some domestic spice manufacturers and research institutes have successively carried out research and production of tobacco extracts, such as using tobacco raw materials to extract with water, acidifying the extract, distilling and concentrating the extract after acidifying, re-distilling the concentrate to obtain volatile oil, and extracting the concentrate Precipitate with alcohol, add volatile oil after recovering alcohol to get tobacco extract, but, so far, domestic tobacco extract varieties are still relatively small, the quality still needs to be further improved, and the preparation process and equipment used are also more complicated. This hinders the further development of the tobacco industry. For this reason, the industry department urgently hopes that the relevant scientific and technological personnel can provide a cheap, high-quality, simple and easy method to improve and improve the aroma of tobacco extract, so as to promote the technological progress of the tobacco industry.
[0003] During the cigarette production process, the tobacco powder is discarded because the physical indicators do not meet the production and processing requirements, but it still contains some useful ingredients

Abstract

The invention discloses a preparing method for a tobacco-made extract. The invention includes the following steps: tobacco leaves are firstly blended with water and enzyme for enzymolysis; and then ethanol is applied for extraction, filtration and concentration; and lastly the tobacco-made extract is obtained through maillard reaction. The invention utilizes the tobacco dust generated from the tobacco production, takes into full consideration the feasibility and operability of industrial production with respect to the preparing process, and furthermore, conducts a series of exploration on factors relating to the enzymolysis, extraction and maillard reaction forms the final preparing process and optimal technical parameters, and thereby the product quality reaches the requirements for adding fragrance to the tobacco-made extract with outstanding steadiness and repeatability.

Description

Technical field [0001] The invention relates to the technical field of tobacco production, in particular to a method for preparing a tobacco extract. Background technique [0002] Tobacco extract is a dark brown viscous paste with the characteristic aroma of tobacco. Tobacco extract can be used in tobacco flavors to enhance and supplement the natural aroma of the inherent characteristics of tobacco, and to cover up the local flavor of tobacco leaves in a single area. Recently, some domestic fragrance manufacturers and scientific research units have successively carried out the research and production of tobacco extract, such as the use of water extraction of tobacco raw materials, acidification of the extract, and distillation and concentration of the extract after acidification. The concentrate is re-distilled to obtain volatile oil and the concentrate of the extract. Tobacco extract is obtained by precipitation with alcohol and the addition of volatile oil after alcohol recove...
