Abstract
The invention discloses a preparation method of a sweet potato ethanol extract. The preparation method comprises the following steps: mixing up sweet potatoes with ethanol so as to prepare sweet potato pulp, depressurizing the sweet potato pulp to obtain a filtrate, and concentrating the sweet potato pulp at 40-45 DEG C under the pressure of 60-70KPa, so as to obtain the sweet potato ethanol extract, wherein the mass content of solid substances in the sweet potato ethanol extract is 5-15%. When the sweet potato ethanol extract prepared by using the preparation method is uniformly sprayed to tobacco shreds in a tobacco leaf feeding procedure, the fragrance of 'baking sweetness' of the cigarette is highlighted, and then the smoking quality and the feeling comfort level of the cigarette are improved, the fragrance of the cigarette is greatly improved, the remaining favor is improved, and the irritation and the impure favor are greatly reduced. The sweet potato ethanol extract is low in product cost, simple in process and high in security, and is applicable to popularization and application in the whole industry.
Description
Technical field
The invention belongs to extracted form natural plant and applied technical field, be specifically related to a kind of sweet potato ethanol extract, its preparation method and the application in cigarette.
Background technology
In recent years, along with the deep propelling of China's tobacco business " lowering harm and decreasing coking " engineering, domestic tar content in cigarette presents the good situation reduced year by year.At the end of the seventies in last century, China's tar content in cigarette mean value is 30 milligrams/, and through industry consistent efforts, by 2009, national tar content in cigarette mean value significantly drops to 12.2 milligrams/.Because " falling Jiao " will inevitably lose part aroma quality and the perfume quantity of cigarette, cigarette taste will be made to lose original style.At present, the problem that cigarette flavor is inadequate, strength is not enough has become the biggest obstacle that restriction low tar product further develops.Therefore, find Novel tobacco perfume material that is a kind of and the fragrant high fit of cigarette cigarette, make up cigarette flavor loss, and then the cigarette product developing " high fragrance, low tar, less harmful " is the only way of Chinese-style cigarette development.
Roast sweet potato is the time-honored bakery product of China, and its strong, tempting roasting sweet fragrance is liked by masses deeply.No matter in chemical fundamentals or nasal receptor, roast sweet potato fragrance all has the uniformity of height with cigarette " roasting fragrant and sweet rhythm ".But, up to now, sweet potato is baked sweet fragrance material and be applied to cigarette blending field and be not reported in theoretical research and industrial practice.Thus, develop a kind of roast sweet potato spices, for cigarette blending work, there is great theory and realistic meaning.
Summary of the invention
The object of the present invention is to provide a kind of sweet potato ethanol extract, provide the preparation method of this extract simultaneously; Another object of the present invention is to the application that this sweet potato ethanol extract is provided.
For achieving the above object, the present invention adopts following technical scheme:
The preparation method of sweet potato ethanol extract of the present invention, comprise the steps such as cleaning peeling, crushing and beating, filtration under diminished pressure and reduced pressure concentration, concrete operations are as follows:
(1) sweet potato carries out pre-treatment, and pre-treatment comprises the following steps: go sweet potato remove surperficial silt and drain with clear water, wipe epidermis with iron wire ball, be cut into the sheet of thickness about 5 ~ 6mm;
(2) sweet potato and ethanol are mixed with sweet potato slurry, sweet potato slurry filtration under diminished pressure (utilizing Buchner funnel to filter) obtains filtrate;
(3) at 40-45 DEG C, concentrated filtrate under 60-70KPa, obtain sweet potato ethanol extract, wherein in sweet potato ethanol extract, the mass content of dry is 5-15%.
Preferably, described single sweet potato diameter is 7-9cm, and weight is 200-400g.
Preferably, in step (1), the mass ratio of sweet potato and ethanol is 1: (1-8); Step utilizes high-speed tissue mashing machine to pull an oar in (1), and 10000-12000 r/min pulls an oar 1-20min.
The application of sweet potato ethanol extract in cigarette that said method obtains, sweet potato ethanol extract adds before baking silk, and its addition is the 0.1-3% of pipe tobacco weight; Sweet potato ethanol extract adds after baking silk, and its addition is the 0.01-2% of pipe tobacco weight.
Adopt thermal cracking gas chromatography-mass spectrometric determination sweet potato ethanol extract, its pyrolysis product is based on furfural, maltol, isomaltol, 2-ethyl-3-methylpyrazine etc. " roasting sweet " fragrance matter.Sensory evaluating smoking's result shows, compared with contrast cigarette, cigarette " roasting sweet " note adding sweet potato ethanol extract obviously strengthens, and comfort promotes, and excitant reduces, and has sense of significantly promoting the production of body fluid.
The present invention utilizes sweet potato ethanol extract at pipe tobacco baking and cigarette burning process generation Maillard reaction just, release " roasting fragrant and sweet " this mechanism, by being evenly sprayed onto on pipe tobacco at cigarette charging process, highlighting cigarette " roasting sweet " note, and then improving its sucking quality and sense organ comfort level.
Compared with prior art, remarkable advantage of the present invention has:
(1) with low cost: the present invention has abandoned traditional tobacco aromatics and to have had drawn from famous and precious vegeto-animal thinking inertia, and select cheap and easy to get, widely distributed sweet potato is raw material, can not increase the production cost of cigarette.
(2) simple process: the present invention does not relate to the complex operations processes such as separation, purifying, without the need to large-scale instrument and equipment and expensive reagent, because starch is dissolved in ethanol hardly, therefore the present invention can save destarch operation.
(3), there is not toxic reagent residue problem in safety and sanitation: raw and auxiliary material of the present invention is all widely used in food processing field.
