Abstract
The invention relates to a preparation method of a vanilla perfume for cigarettes, comprising the following steps: carrying out reflux extraction on vanilla beans with a fat-soluble solvent, condensing while depressurizing to remove the fat-soluble solvent and obtain a primary paste, redissolving the primary paste with an alcohol extracting agent, freezing and storing the redissolved solution, then carrying out filtration on the redissolved solution, and condensing the filtrate while depressurizing to obtain first vanilla perfume; carrying out reflux extraction on the vanilla beans with a water-soluble solvent after the vanilla beans are subjected to reflux extraction of the fat soluble solvent, then carrying out filtration, and condensing the filtrate while depressurizing to obtain second vanilla perfume; and carrying out the reflux extraction on the vanilla beans with another water-soluble solvent after the vanilla beans are subjected to the reflux extraction of the water-soluble solvent, condensing while depressurizing, then redissolving with the alcohol extracting agent, freezing and storing the redissolved solution, carrying out filtration on the redissolved solution, and condensing the filtrate while depressurizing to obtain a third vanilla perfume. According to the invention, the separation of the fat-soluble components and water-soluble components of the vanilla beans can be realized, thereby facilitating the follow-up processing of the crude extract, increasing the total extract yield of the raw material, comprehensively utilizing the raw material, and completely extracting and separating active perfume ingredients from the raw material.
Description
Technical field
The present invention relates to the preparation method of tobacco aromatics using, belong to technical field of tobacco, specifically is raw material with the XIANGJIALANDOU, according to the characteristics of XIANGJIALANDOU chemical ingredients, utilizes the method for specific extraction and separation technology segmentation production characteristic tobacco aromatics using.
Background technology
Vanilla (Vanilla planifolia Andr.) has another name called vanilla, Herba vanillae Planifoliae, Vanilla annamica, has the good reputation of " king of food spice ".The country of origin of vanilla is a Mexico, is a kind of large-scale the orchid family spice berry that is grown in the tropical rain forest.At present, the cultivation area of vanilla mainly concentrates on island state or areas such as Madagascar, Indonesia, Comoros, Liu Wangni, Uganda, Seychelles, Mexico and Tahiti.China introduces vanilla in nineteen sixty from Indonesia, plants in Fujian, ground such as Hainan, Guangxi and Yunnan, because the advantageous physical environment in Yunnan, vanilla is the most successful in the cultivation in Yunnan, at present existing nearly 1000 mu cultivated area, stable yield, best in quality.
The fragrance of vanilla is fresh and sweet creamy, and human body is had joyful, comfortable impression, many rhythms that give off a strong fragrance, and lasting is lasting, long times of aftertaste.The XIANGJIALANDOU extract uses in tobacco, food, makeup in a large number at present, and the flavouring effect is fairly obvious.What is particularly worth mentioning is that the XIANGJIALANDOU extract is applied on the tobacco, can play pure and mild flue gas, coordinate smoke, increase cigarette perfume (or spice), the just fragrant fine and smooth soft effect of cigarette.
Adopt solvent-extraction process directly to concentrate the back for the extraction of vanilla spices at present obtains more, this method can not effectively be extracted spices at the characteristics that XIANGJIALANDOU had not only contained fat-soluble ingredient but also contained water soluble ingredient, the total extractives yield of raw material is lower, can not fully utilize and differently in raw material and the abundant extracting and separating raw material effectively cause fragrant component, so that the different spice products of gained are suitable for the reinforced effect characteristics of perfuming cigarette, also be not easy to the following process and the processing of crude extract.
Summary of the invention
The objective of the invention is to solve the deficiencies in the prior art, providing a kind of is raw material with the XIANGJIALANDOU, can realize separating of XIANGJIALANDOU fat-soluble ingredient and water soluble ingredient, be convenient to the following process and the processing of crude extract, can improve the total extractives yield of raw material, reach the comprehensive utilization raw material and fully effectively cause the preparation method of the cigarette of fragrant component in the extracting and separating raw material with vanilla spices.
The objective of the invention is to be achieved through the following technical solutions.
The cigarette preparation method of vanilla spices, segmentation according to the following steps prepares vanilla spices:
1. with XIANGJIALANDOU by after the fat-soluble solvent refluxing extraction, behind the concentrating under reduced pressure weeding of grease soluble solvent first cream, with this just cream carry out suction filtration after returning the freezing preservation of solution with pure kind of extractants Hui Rong, filtrate decompression is obtained first kind of vanilla spices after concentrated;
2. the XIANGJIALANDOU after the fat-soluble solvent refluxing extraction is used the water-soluble solvent refluxing extraction again, suction filtration, filtrate decompression concentrate and obtain second kind of vanilla spices then;
3. the XIANGJIALANDOU after the water-soluble solvent refluxing extraction is used again another kind of water-soluble solvent refluxing extraction, with pure kind of extractants Hui Rong, after time freezing preservation of solution, suction filtration obtains the third vanilla spices after filtrate decompression is concentrated behind the concentrating under reduced pressure.
The present invention prepares the method for first kind of vanilla spices, it is the segment that XIANGJIALANDOU is cut into 1～2cm, add doubly by 3～6 of XIANGJIALANDOU weight and to add fat-soluble solvent, refluxing extraction three times, each 1～3 hour, the extracting solution concentrated cream just that obtains under reduced pressure with obtaining obtained back solution with first cream with pure kind of extractants Hui Rong again, to return solution and leave standstill freezing 6～24 hours after-filtration under-10～-20 ℃, concentrating under reduced pressure gets final product.The method of second kind of vanilla spices of preparation, after being the residual solvent in the XIANGJIALANDOU after the weeding of grease soluble solvent extracts, add the adding water soluble solvent doubly by 5～8 of XIANGJIALANDOU weight, twice of refluxing extraction, each 1～3 hour, with the extracting liquid filtering that obtains after concentrating under reduced pressure get final product.The method for preparing the third vanilla spices, be that XIANGJIALANDOU after water-soluble solvent is extracted is with twice of 4～6 times another kind of water-soluble solvent refluxing extraction, each 1～2 hour, with behind the extracting solution concentrating under reduced pressure that obtains with pure kind of extractants Hui Rong, suction filtration after leaving standstill freezing 6～24 hours under-10 ℃～-20 ℃ concentrates filtrate decompression and gets final product.Water-soluble solvent of the present invention is the double solvents of water, alcoholic solvent or water and alcoholic solvent; Described pure kind of extractants is ethanol or propylene glycol; Described fat-soluble solvent is sherwood oil or ethyl acetate or propyl carbinol or chloroform or ether.
The inventive method has following characteristics: by the stage extraction of opposed polarity solvent, can realize separating of XIANGJIALANDOU fat-soluble ingredient and water soluble ingredient, be convenient to the following process and the processing of crude extract.The method of stage extraction has improved the total extractives yield of raw material, has reached the purpose that effectively causes fragrant component in comprehensive utilization raw material and the abundant extracting and separating raw material.The a whole set of technological process of the inventive method is simple, and required equipment is simple, can be implemented in the wire gauge modelling and produce, and is easy to utilize.The spices that this method is produced can play pure and mild flue gas, coordinates smoke, increases cigarette perfume (or spice), makes the fragrant fine and smooth soft effect of cigarette.
