Problems solved by technology

This patent uses fermentation, which takes a long time and costs a lot. After the extract is concentrated, it is spray-dried at a temperature of 60-100°C to obtain a powdered tobacco flavor product. The temperature is still too high, which will easily lead to the destruction of the chemical structure of the natural flavor components. (including oxidation, polymerization and decomposition, etc.) and the loss of aroma components

Abstract

The tobacco flavor extracting process includes the following steps: 1. crushing tobacco and setting in extracting tank; 2. adding solvent in 2-16 times the weight of tobacco to the extracting tank; 3. decompression reflux extracting at 20-60deg.c temperature and 0.020-0.098MPa vacuum degree for 1-8 hr; and 4. separating the liquid extract through filtering, and decompression concentrating the filtrate at vacuum degree of 0.020-0.098MPa to obtain the tobacco flavor of density 1.1-1.4g/ml. The extracting process is simple, safe, environment friendly, high in extracting efficiency and low in production cost, and the extracted tobacco flavor has the physical and chemical properties of natural tobacco components and may be added to cigarette to improve flavor, raise quality and lower tar.

Description

technical field [0001] The invention relates to a method for extracting flavors and fragrances, in particular to a method for extracting tobacco flavors and fragrances. Background technique [0002] At present, cigarette markets in various countries require cigarette products to have the attributes of "high aroma, high concentration, and low tar". However, for tobacco with poor quality, dark color, low oil content, and insufficient flavor, it is necessary to add exogenous artificially synthesized flavors and fragrances or add imported high-quality tobacco leaves to make up for and improve the defects of tobacco, so as to meet the needs of the consumer market . However, with the improvement of people's living standards and the continuous strengthening of health awareness, as well as the increasing calls for reducing tar and reducing harm, the extraction and application of natural flavors and fragrances, especially the extraction of flavoring substances from high-quality toba...
