Abstract
The invention discloses a preparation method for cabo extractive with the assistance of steam explosion and belongs to the technical field of extraction of cigarette flavor. The preparation process is carried out according to the following steps sequentially: (1), dust in dried caboes is removed; (2), the caboes after dust removal are subjected to steam explosion at the steam pressure of 0.9 to 1.0 MPa; (3), the caboes after steam explosion are backflowed and extracted with alcohol which is 50 to 55 percent in weight percentage, so as to obtain a concentrate; and (4), 95 percent alcohol which is 3.0-3.5 times of the weight of the concentrate is added in the concentrate, the concentrate is placed under an environment of (-10) to (-5) DEG C to naturally subside, and is filtered and concentrated under reduced pressure, and then the cabo extractive is obtained. The cabo extractive prepared with the method provided by the invention has the obvious effect of enabling the smoke gas to be delicate, improving the aroma and reducing stimulation, and plays a slight role in covering up miscellaneous gas.
Description
Technical field
The invention belongs to the extractive technique field of tobacco aromatics using, be specifically related to the preparation method of the auxiliary offal extract of a kind of steam blasting.
Background technology
Offal is the important component part of tobacco leaf, accounts for leaf and weighs 25%～30%.As tobacco big producing country, China approximately has few hundred thousand tonnes of tobacco stem waste to be thrown aside waste every year.The current main form of utilizing of offal is stem etc. for extraction nicotine, Salanesol, reconstituted tobacoo processed and cigarette.With offal be raw material prepare offal extract be applied to cigarette in recent years also to some extent development, but because the main component of offal is the cell membrane class materials such as pectin, lignin, cellulose, hemicellulose, the offal extract fragrance being prepared into is obviously not enough, and recovery rate is low, restricted to a certain extent the application of offal extract in cigarette flavoring essence.
Steam blasting is mainly to utilize high-temperature high-pressure steam to process fibrous raw material, and by moment pressure leak process realize component separation and the structural change of raw material.In prior art, steam blasting is mainly used in the pretreatment of raw material of papermaking and cellulose ethanol.Patent (publication No. CN101912149A) has been announced the method that applying steam explosion and enzyme treatment technique improve tobacco stalk quality; Patent (publication No. CN101933656A) has been announced applying steam explosion and has been combined with microwave irradiation technology and improve the method for cabo quality; These two kinds of main applying steam explosions improve the quality of stem.It is the object of Studies of The Aromatic Substances release processed in hemicellulose and lignin and offal that the present invention utilizes steam blasting to reach cellulose conversion in offal.Offal extract with the auxiliary preparation of steam blasting can improve its suction quality, expands its application percentage in cigarette.
Summary of the invention
The preparation method who the object of this invention is to provide the auxiliary offal extract of a kind of steam blasting.The offal extract that preparation method of the present invention obtains can be coordinated well with cigarette, can improve the smoking quality of cigarette, is a kind of good cigarette additive, can successfully be applied in cigarette flavoring essence.
In the present invention, the preparation method of the auxiliary offal extract of a kind of steam blasting, comprises the following steps:
(1) the dry offal that ovennodulation, alcoholization process of learning from else's experience, gets express developed and removes surface adhesion dust with clear water;
(2) under the condition that the offal after dedusting is 0.9-1.0MPa at steam pressure, carry out steam blasting, the steam blasting time is less than 0.01s, and the dwell time is 20-25s;
(3) alcohol reflux that the offal after steam blasting is 50%～55% by percetage by weight extracts:
Offal after steam blasting adds the ethanol that the percetage by weight of 10 times of amounts of its gross weight is 50%～55%; In temperature, be refluxing extraction 2 times under 95 ± 2 ℃ of conditions, for the first time 2.5h, for the second time 2h; Merge extracted twice liquid, it is 1.200 ± 0.006g/cm that the extract after merging is concentrated into density under 30-45 ℃ of condition
3, gained is concentrate A;
(4) in described concentrate A, add 95% ethanol of 3.0～3.5 times of amounts of its weight, mix and be placed under-10 ℃～5 ℃ environment, natural subsidence 12h-36h, normal temperature filters, gained filtrate at pressure is-0.08MPa～0.1MPa, temperature is to carry out reduced pressure concentration under 30-45 ℃ of condition, makes concentrated solution density reach 1.000 ± 0.006g/cm
3, gained liquid is offal extract of the present invention.
The cigarette making adds the cigarette in cigarette by the weight of offal extract, to account for the 0.08%-0.12% of tobacco leaf weight while being applied to cigarette with offal extract.
The good technical scheme of the present invention is:
(1) the dry offal that ovennodulation, alcoholization process of learning from else's experience, removes surface adhesion dust;
(2) under the condition that the offal after dedusting is 0.95MPa at steam pressure, carry out steam blasting, the steam blasting time is less than 0.01s, and the dwell time is 20s;
(3) offal after steam blasting adds the ethanol that the percetage by weight of 10 times of amounts of its gross weight is 50%; In temperature, be refluxing extraction 2 times under 95 ± 2 ℃ of conditions, for the first time 2.5h, for the second time 2h; Merge extracted twice liquid, it is 1.200 ± 0.006g/cm that the extract after merging is concentrated into density under 40 ℃ of conditions
3, obtain concentrate;
(4) in concentrate, add 95% ethanol of 3.0 times of amounts of its weight, mix and be placed under-10 ℃～5 ℃ environment, natural subsidence 24h, normal temperature filters, gained filtrate at pressure is-0.08MPa～0.1MPa, temperature is to carry out reduced pressure concentration under 40 ℃ of conditions, makes concentrated solution density reach 1.000 ± 0.006g/cm
3, gained liquid is offal extract of the present invention.
In the present invention, the preparation method of the auxiliary offal extract of steam blasting is simple to operate, and resulting product can coordinate well with cigarette, is applied in cigarette and has the effects such as flavouring, lifting fragrance matter, fine and smooth flue gas, increases the suction quality of cigarette.
