Embodiment 1

[0025] Example 1 Preparation of Endogenous Flavors from Izmir Tobacco

[0026] (1) Solvent extraction: Weigh 200g of Izmir tobacco leaves, pick out the rope ends and moldy tobacco leaves, wash and remove impurities, and grind them into 50-200 mesh powder after drying; add ethanol for extraction, and the quality of the extracted materials The ratio is tobacco raw material: ethanol = 1:7~9, heat reflux (above 50°C) extraction for 1.5~3 hours, extract 1~3 times, and combine the extracts;

[0027] (2) Preparation of crude extract: After filtering the extract obtained in step (1), carry out vacuum distillation at a vacuum degree of 0.02-0.08Mpa and a temperature of 50-80°C to obtain the crude extract of Izmir oriental tobacco;

[0028] (3) Alkalinization: According to the mass ratio of the crude extract and petroleum ether as 1:3, add the extraction solvent petroleum ether to the crude extract of Izmir spice tobacco obtained in step (2). The crude tobacco extract is stirred and r...

Abstract

The invention discloses an endogenous perfume from tobacco as well as a preparation method and application thereof. In the preparation method, the special endogenous perfume can be produced from Izmir perfume tobacco by the process steps of lixiviating, alkalifying, extracting, acid cleaning, concentrating and the like and an acid-base separation method. The special endogenous perfume from tobacco has the characteristics of good solubility, sweet taste and high-quality imported tobacco and aged tobacco aroma and the like. According to the invention, application of Izmir tobacco raw material is broadened. The endogenous perfume from tobacco can be directly and conveniently added in cigarettes or tobacco sheets, can obviously improve the aroma and smoking taste quality of the cigarettes, make smoke fine and soft, enhance aged tobacco aroma and improve mouthfeel.

Description

technical field [0001] The invention belongs to the technical field of preparation of tobacco essence and fragrance, and in particular relates to a tobacco endogenous fragrance and its preparation method and application. technical background [0002] Tobacco flavors and fragrances are the basic raw materials for cigarette flavoring, and their development and innovation have attracted much attention. From the perspective of raw materials, the existing flavors and fragrances for tobacco can be classified into tea, fruits and vegetables, fragrant flowers, seeds, Chinese herbal medicines, tobacco and the like. Compared with the previous types of tobacco flavors and fragrances, tobacco flavors and fragrances, that is, endogenous flavors and fragrances of cigarettes, can increase the natural tobacco aroma and aroma of old tobacco, increase the concentration of smoke, control the roughness of smoke or improve the softness of smoke And it plays an irreplaceable role in coordinating...
