Problems solved by technology

Although there are many natural plants that have been reported to reduce cigarette free radicals, almost none of them are actually used in industrial production and bring direct and significant economic benefits. The key reason is that they cannot solve the negative effects of plant additives on cigarette smoking.

Abstract

The invention discloses a purple perilla step-by-step extracting method and an application of an obtained extract in a cigarette, belonging to the technical field of the aroma and the flavor of a cigarette. The purple perilla step-by-step extracting method comprises the following steps: 1. soaking raw materials at normal temperature; 2. extracting volatile oil to obtain an extract A; 3. filtering the extract A to obtain filter liquid; 4. precipitating alcohol after concentration to obtain an extract B; and 5. leading the extract B to pass through a film and concentrating the extract B to obtain an extract C. The extract A, the extract B and the extract C are added into tobacco shreds after being singly or compositely proportioned to enable a cigarette to have the special aroma of purple perilla or the effects of coordinating and enriching the aroma, tendering and weakening smoke, reducing simulation and increasing taste or the effect of oxidation resistance or the effect of reducing a free radical of smoke or the comprehensive effect. The invention has the advantages of easy extracted raw material purple perilla leaf acquisition, low cost, good purple perilla use effect and high safety, has a better positive effect on the aroma, the remaining taste and the comfortable feeling of the cigarette and can reduce the free radical in the cigarette and play the roles of damage reduction and tar lowering.

Description

technical field [0001] The invention belongs to the technical field of cigarette flavors and fragrances, and in particular relates to a step-by-step extraction method of special medicinal material perilla and the application of the obtained extract in cigarettes as tobacco flavors. Background technique [0002] Perilla is an annual herb of Lamiaceae, also known as Huihuisu, red perilla, red perilla, red perilla, perilla, etc. It is a temperature-loving crop with strong adaptability and is not strict with environmental conditions and soil conditions. In February 1979, the Food and Agriculture Organization of the United Nations and the World Health Organization jointly convened the thirteenth meeting of the Codex Committee on Nutrition to discuss the draft standard for the content of erucic acid in edible vegetable oil to be less than 5%. Development research is valued and developed rapidly. In addition to being a new type of oil crop without erucic acid, perilla also has man...
