Preparation method of moss-scented tobacco flavor and application of moss-scented cigarette flavor in cigarette flavoring

Abstract

The invention discloses a preparation method of a moss-scented tobacco flavor, which comprises the following steps: (1) evenly mixing raw material tree moss concrete or oak moss concrete and an entraining agent in the mass ratio of 1:3-6 to obtain a raw material solution system, and degassing for 4-6 minutes; (2) separating and purifying the raw material solution system into three stages of fractions by using a molecular distillation device, wherein the conditions for molecular distillation are as follows: the charging rate is 2-5ml / min, the distillation temperature is 50-110 DEG C, the absolute pressure is 0.1-50Pa, the rotation speed of a film wiper is 100-300 r / min, the condensation water temperature in the first and second stages is 1-10 DEG C, and liquid nitrogen is used for cooling in the third stage; and collecting the fraction in the first stage. The moss-scented tobacco flavor is a uniform, clear and stable liquid flavor; impurities are removed from the moss-scented tobacco flavor without introducing new impurities and toxic substances; the relative content of the key scent components for forming the scent feature is higher than 80%; and the preparation method in the invention has the advantages of mild technological conditions, no emission of waste water, waste gas and waste residue, and low production cost, and has wide application prospect in cigarette flavoring.

Description

technical field [0001] The invention relates to the field of preparation of tobacco spices, in particular to a method for preparing moss-flavored tobacco spices and its application in cigarette flavoring. Background technique [0002] Treemoss and oakmoss extract is a paste obtained by leaching (extracting) Usnea family epiphytic lichens with volatile organic solvents (commonly used petroleum ether) and then distilling and recovering the solvent. It has a unique natural fragrance and It has a strong resinous smell and is an important natural fragrance. At present, major tobacco companies and their research institutions have increasingly used tree moss and oakmoss extracts to give cigarette products a unique aroma style. [0003] However, there are some problems that are difficult to solve when these two extracts are applied to cigarette flavoring and adding materials. One is that the spices contain a lot of impurities such as pigments and vegetable waxes, which lead to poo...

Problems solved by technology

But these methods all take preparing absolute oil as the ultimate goal, without considering the production cost and price of the product, when the extract is further processed into absolute oil for use, the price of the absolute product will obviously rise, and more importantly, the processing process does not Fully considering the enrichment and capture of key aroma components in the extract, the aroma quality and purity of the absolute oil cannot be greatly improved compared with the original extract

Moreover, there are no literature reports and patents on the application of molecular distillation technology to process tree moss and oakmoss extracts, and there are no relevant patents and literature reports on the direct preparation of moss-flavored spices by molecular distillation technology.

[0006] And if molecular distillation technology is used to process tree moss and oakmoss extract into absolute oil and then use it, there are also some more prominent problems. First, although the quality of absolute oil is improved compared with traditional processing methods, the quality of absolute oil Yield is difficult to obviously improve, the 2nd, in the preparation process of tree moss and oakmoss extract, need to carry out distillation recovery to the organic solvent used for extraction, the residual amount of organic solvent in tree moss and oakmoss extract is very low, causes its viscosity very Large, poor fluidity, easy to damage the molecular distillation equipment during direct processing, third, the comprehensive utilization efficiency of extract raw materials is low, and the added value of the product is not high
