Description
Technical Field
The application relates to the technical field of cigarette manufacturing, in particular to a walnut shell extract for cigarettes, a preparation method and cigars.
Background
Cigars are a unique tobacco product, and traditionally cigars refer to smoking cigarettes that are all manually wrapped with tobacco leaves. The cigar has the characteristics of rich fragrance, unique cultural charm and the like, is accepted by a plurality of tobacco consumers in recent years, and the development of the domestic cigar enters a rapid rising stage after the restriction factors such as production process, equipment and the like are gradually solved. In our country, cigars are an emerging tobacco product, and although the consumption is far less widespread than cigarettes, in recent years, the scale of cigar production in China is rapidly increasing, and the demand for raw materials is more demanding in terms of quantity and quality.
The walnut shells are byproducts of the kernels of walnuts, are hard, are generally discarded or burnt as wastes in the processing and kernel taking processes, have low utilization value and cause resource waste and environmental pollution. In order to enhance the full utilization of walnut shell resources and produce products with high added value, a great deal of research is also carried out by domestic and foreign scholars on the application research of walnut shells, and the study is mainly focused on the production of active carbon, the extraction of brown pigment, antioxidants and anti-aggregation agents, filter materials and plugging materials in filters, the processing of organic diluting fertilizers and the like. However, there have been few studies on the application of the baked walnut shells as cigars.
At present, most of common natural spices are obtained by extracting natural spices by a traditional extraction method, and the natural spices which can be developed are limited by a permitted list of tobacco additives, and the quality problems of the domestic cigar tobacco leaves cannot be solved in the aspects of aroma, taste and the like of the prepared spices.
Disclosure of Invention
In order to solve the technical problems, the first object of the invention is to provide a preparation method of walnut shell extract for cigarettes; the second purpose of the invention is to provide a walnut shell extract for cigarettes, and the third purpose of the invention is to provide cigars; the walnut shell extract for the cigarette can obtain more effective components from the walnut shells through the soaking and baking process of the maltitol aqueous solution, so that the prepared walnut shell extract for the cigarette has a better effect on solving the problems of green and impure flavor and bitter taste of the cigar leaves after being added into the cigar leaves as spice, and brings more comfortable cigar experience feeling to smokers.
The technical scheme provided by the invention is as follows:
a preparation method of a walnut shell extract for cigarettes comprises the following steps:
crushing walnut shells to obtain walnut shell powder;
placing the walnut shell powder in the maltitol aqueous solution, uniformly mixing and soaking;
baking the soaked walnut shell powder;
adding water into the baked walnut shell powder, carrying out ultrasonic extraction, and carrying out primary filtration to obtain a water extract;
adding ethanol into the water extract for precipitation, filtering for the second time, and concentrating the filtrate to obtain the walnut shell extract for the cigarettes.
Preferably, the walnut shells are crushed and then screened by a 20-40 mesh screen to obtain the walnut shell powder.
Preferably, the walnut shell powder is put into the maltitol aqueous solution to be uniformly stirred and soaked for 24-30 h.
Preferably, the mass fraction of the aqueous solution of maltitol is between 20% and 40%.
Preferably, the soaked walnut shell powder is baked at the temperature of 120-140 ℃ for 3-5 h.
Preferably, the mass ratio of the baked walnut shell powder to the water is 1:5-1: 10.
Preferably, the power of ultrasonic extraction is 350-450w, and the time of ultrasonic extraction is 20-40 min.
Preferably, the aqueous extract is concentrated to a relative density of 1.1 to 1.2g/cm 3 Then adding ethanol with the mass 5-10 times of the concentrated water extract for precipitation; second filtering, and concentrating the filtrate to relative density of 1.1-1.2g/cm 3 And obtaining the walnut shell extract for cigarettes.
A walnut shell extract for cigarettes is characterized by being prepared by any one of the preparation methods.
A cigar is prepared by uniformly coating the walnut shell extract for cigar on cigar tobacco leaf at a weight ratio of 0.5-1.5%, balancing at 22 + -2 deg.C and humidity of 60 + -5% for 48 hr, and rolling into cigar.
The preparation method of the walnut shell extract for cigarettes is different from a traditional spice extraction method, and the walnut shell powder is soaked in a maltitol aqueous solution and baked before being extracted by purified water, and then is subjected to ultrasonic extraction. More effective components can be obtained from walnut shells through the soaking and baking processes of the maltitol aqueous solution, so that the prepared walnut shell extract for the cigarette can be used as a spice to be added into cigar tobacco leaves, has a better effect on solving the problems of green miscellaneous gas and bitter and hungry taste of the cigar tobacco leaves, and brings more comfortable cigar experience feeling to smokers.
