Tobacco flavor extraction method

Abstract

The invention discloses a tobacco flavor extraction method which comprises the following steps: preheating multifunctional steam distillation-dry distillation integrated equipment, and adding a tobacco raw material into a steam distillation-dry distillation device after the temperature is stable; the method comprises the following steps: introducing superheated steam and nitrogen into a steam distillation-dry distillation device together, and heating to increase the steam distillation-dry distillation temperature; collecting distillate of each temperature section according to the temperature; extracting the distillate of each section by using a solvent to obtain extract liquor; and dehydrating the extract liquor, and carrying out rotary evaporation to recover the solvent, thereby obtaining the tobacco flavor for enhancing the aroma of the novel tobacco product. Compared with the conventional common extraction method, the method has the advantages that the original aromatic substances of the tobacco can be extracted, the tobacco flavor with stronger roast fragrance and scorched sweet fragrance can be obtained, the condition is more mild, the product is more easily steamed out along with water vapor, the yield is improved, the problem of scorched smell caused by uneven heating easily occurring in a dry distillation method is avoided, and the method is suitable for industrial production. The method is especially suitable for aroma enhancement of novel tobacco products.

Description

technical field [0001] The invention relates to the field of novel tobacco products such as heated cigarettes, in particular to a method for extracting tobacco spices. Background technique [0002] Tobacco essential oil is an aromatic substance extracted from tobacco with a characteristic smell of tobacco and is volatile. The main components of tobacco essential oil include terpenes, volatile acids, lipids, aldehydes, aromatic rings, heterocycles, and alkaloids. In the tobacco industry, tobacco essential oils are mainly used for flavoring cigarettes or new tobacco products to improve the sensory quality of cigarettes. [0003] At present, the extraction methods of tobacco essential oil include steam distillation, organic solvent extraction, supercritical CO 2 Extraction and dry distillation. Although the organic solvent extraction method can extract a variety of aroma substances and has a good aroma, there will be a problem of residual organic solvents, which does not con...

AI Technical Summary

Problems solved by technology

Although the organic solvent extraction method can extract a variety of aroma substances and has a good aroma, there will be a problem of residual organic solvents, which does not conform to the green and healthy environment-friendly development concept

Steam distillation is green, safe, high-quality, low-cost, but low oil yield, and the extract lacks roasted flavor

Supercritical CO 2 The operating conditions of the extraction method are harsh, the equipment is expensive, and the product has insufficient roasted aroma

A single dry distillation method is prone to overheating and scorching of raw materials, which seriously affects the quality of the product and is unsafe

[0004] At present, most of the tobacco industry adopts a single method to extract tobacco spices, and the products often have problems such as insufficient roasted flavor or excessive burnt smell, and are directly used for atomization. The taste of the atomized smoke is quite different from that of traditional cigarettes. Meet the requirements for flavoring new tobacco products
