Embodiment 1

[0070] Embodiment 1: the extraction of the spices with fireworks characteristic fragrance of the present invention

[0071] The implementation steps of this embodiment are as follows:

[0072] (1) Raw material pretreatment granulation

[0073] The fireworks raw materials are washed and crushed, and their moisture content is measured. Then, pure water is added to the fireworks raw materials to adjust their moisture content to 14%, and then the fireworks raw materials are extruded and granulated by an extrusion granulator to make the fireworks The particle diameter of granule is 60 orders, obtains 5kg granulated fireworks;

[0074] (2) Supercritical CO 2 fluid extraction

[0075] The granulation fireworks thing that step (1) obtains is carried out supercritical CO 2 fluid extraction, the supercritical CO 2 The conditions of fluid extraction are: the extraction pressure of the extraction kettle is 34MPa, the extraction temperature is 42°C, and the entire extraction process t...

Abstract

The invention relates to a method for extracting a spice with a tobacco-flower characteristic aroma from a tobacco flower. The method comprises steps of pretreatment and granulation of a raw material, supercritical CO2 fluid extraction, molecular distillation separation, compounding and the like. By using the spice with the tobacco-flower characteristic aroma, which is prepared according to the method provided by the invention, the original aroma, the flowery aroma and the sweet aroma of tobacco can be increased; the fragrance is exquisite and strong; the mouth feel is good; a residue dost not exist; as the combination technique of a supercritical CO2 fluid extraction method and a molecular distillation method is used, the method is favorable in the extraction and refinement selectivity on an aromatic substance; the physicochemical stability is high; the operation is simple and convenient; no solvents are introduced; the original-aroma substance of the tobacco flower can be furthest retained; the realization of industrialization of the method is conveniently, quickly and feasibly.

Description

[0001] 【Technical field】 [0002] The invention belongs to the technical field of essence and fragrance extraction. More specifically, the present invention relates to a method for extracting spices with characteristic aroma of fireworks from tobacco flowers. [0003] 【Background technique】 [0004] Tobacco belongs to the genus Nicotiana of the family Solanaceae. At present, there are 66 species of Nicotiana plants discovered in the world. But there are only two species that are widely cultivated, namely common tobacco (N. Tabacum L.) and yellow flower tobacco (N. rustica L.). Common tobacco is also called safflower tobacco, such as flue-cured tobacco, Burley tobacco, oriental tobacco , Maryland tobacco, etc., and Huanghuayan belongs to Huanghua tobacco. Tobacco likes warm and sunny environment, not cold-resistant, more heat-resistant. Likes fertile, deep, well-drained soil. [0005] Fireworks are the flowers discarded from the top of the tobacco tree and the flowers that ...
