Embodiment 1

[0019] Crush the air-dried leaves of Fenugreek to 15-20 meshes or crush the dried Twigs to 15-20 meshes. After the samples were pretreated with 1% hydrochloric acid for 30 min, the samples were mixed with V(acetone):V( water) = 1:1 as the solvent, extracted with an accelerated solvent extraction apparatus at 125 ℃, and collected clear and crude oil of fennel leaves. Add the crude oil of fragrant leaves into the feed bottle for pre-degassing. When the vacuum degree of the system meets the requirements of the equipment, the material enters the molecular distillation device from the feeder at a set flow rate of 350-400 mL·h for distillation. The evaporation pressure is 3-10 Pa, the distillation temperature is 200-220°C, and the speed of the wiper is 300-400 r. min, the feed temperature is 100°C; discard the separated products of light components, and recover the distilled products of heavy components; dissolve the distilled products of heavy components recovered by molecular dis...

Abstract

The invention discloses a preparation method of a pistacia weinmannifolia spice for cigarettes, which comprises the following steps of: carrying out extraction on pistacia weinmannifolia leaves, branches or barks which are dried and crushed to 5-20 meshes by using an accelerated solvent extraction method so as to obtain a pistacia weinmannifolia leaf crude; putting the pistacia weinmannifolia leaf crude into a molecular distillation device under the condition of a high vacuum degree to carry out distillation; collecting a heavy-component separation product; and dissolving the heavy-component separation product into ethanol and propylene glycol in a volume ratio of 70% so as to prepare the pistacia weinmannifolia spice for cigarettes. Through smoke panel test comparison, the pistacia weinmannifolia spice for cigarettes can significantly enhance the richness and exquisite feeling of smoke smell of cigarettes, and can mainly increase the faint scent, spicy flavor, wood flavor, fruity flavor and flower flavor of cigarettes; and the spice is downy in fragrance, blown and elegant in penetrative property, and has good compatibility with the smoke smell of cigarettes.

Description

technical field [0001] The invention belongs to the technical field of flavors and fragrances for cigarettes, and in particular relates to a method for preparing fragrance wood fragrances for cigarettes by using molecular distillation technology. Background technique [0002] Flavoring technology is one of the core technologies to build cigarette brand characteristics and quality style, and flavors and fragrances are the key to flavoring technology. Although domestic flavor and fragrance companies have achieved certain results in the development of various flavors and fragrances, there is still a big gap compared with the world's advanced level, mainly due to the high degree of dependence on foreign flavors and fragrances and the lack of independent core knowledge Fragrance technology and other aspects of property rights. In addition, statistical results show that the use of naturally extracted flavors and fragrances accounts for the majority of the consumption of various f...
