Problems solved by technology

The aroma of the extract obtained by this method is not rich enough, and there are still deficiencies in improving the aroma of cigarettes, improving the aftertaste in the mouth and endowing cigarettes with style characteristics; the invention patent (application number: 201510450486.3) uses different concentrations of ethanol solutions to extract raisins respectively, The raisin extract was prepared by concentrating under reduced pressure. Although the process is simple, the obtained extract has insufficient aroma and cannot better meet the needs of cigarette applications; the invention patent (application number: 201510993232.6) uses supercritical CO2 to extract raisins. However, since this method can only extract non-polar components in raisins, the extraction rate is low and the cost is too high

Embodiment 1

[0024] Embodiment 1: a kind of preparation method of raisin distillate for tobacco is characterized in that concrete steps comprise:

[0025] (1) Take a certain quality of raisins, crush the raisins raw materials to about 1 / 3 of the original volume, add tap water 6 times the weight of the processed raisins raw materials, and conduct dynamic countercurrent extraction at 60°C for 2.5 hours. After the extraction, Rough filtration obtains filtrate A;

[0026] (2) Add 2.5 times the amount of 85% ethanol aqueous solution to the raisin slag extracted in step (1), conduct ultrasonic extraction for 3 hours at a temperature of 45° C. and an ultrasonic frequency of 60 kHz, and after the extraction is completed, coarsely filter to obtain the filtrate B;

[0027] (3) Slowly pour the filtrate A extracted in the step (1) into the filtrate B extracted in the step (2), stir while adding, make it fully mix, then put the combined extract at -0.095MPa , under the condition of 52°C, concentrate ...

Abstract

The invention provides a preparation method for raisin distillate for cigarettes. The method comprises the following steps that raisin raw materials are crushed, water is added, dynamic countercurrentextraction is carried out, filtrate is collected, an ethanol aqueous solution is added into raisin slag materials, ultrasonic extraction is carried out, filtrate is collected again, the two filtratesare merged and are subjected to vacuum concentration so as to obtain a raisin concentrated solution, then a self-screened strain SX004 is added, uniform stirring is carried out, then sealed fermentation is carried out, 95% ethanol is added into fermentation liquor after fermentation is completed, uniform stirring and standing are carried out, supernate is taken, filtering is carried out, filtrateis subjected to vacuum concentration so as to obtain a raisin refined solution, then lysine and glycerol are added, uniform stirring is carried out, heating is carried out for reaction so as to obtain molecular distillation pretreatment liquid, the molecular distillation pretreatment liquid is subjected to molecular distillation separation, and a molecular distillation light component is collected so as to obtain the raisin distillate. The raisin distillate prepared through the preparation method has the advantages of being rich in fragrance, capable of achieving the effects of enriching thecigarette fragrance, improving the aroma quality, reducing the stimulating feeling of an oral cavity and improving the agreeable aftertaste in the oral cavity and relatively ideal in application effect in the cigarettes.

Description

technical field [0001] The invention relates to a method for preparing tobacco spices, in particular to a method for preparing raisin distillate for tobacco. Background technique [0002] Raisins are the fruits of grapes dried in the sun or in the shade. They are soft, sweet, nutritious, and contain a lot of glucose, various minerals, amino acids and vitamins, and are very popular among people. [0003] From the current literature reports, it can be seen that the research on raisin-related technologies mainly involves the fields of food, beverages, cosmetics, etc., but there are few reports on tobacco flavors. Among them, the invention patent (application number: 201710541488.2) first adopts biological preparations to hydrolyze and ferment raisins to freeze The pulverized product is subjected to reflux extraction, vacuum concentration and membrane filtration, and the prepared filtrate is the raisin extract. The aroma of the extract obtained by this method is not rich enough...
