Description

A kind of preparation method of natural spice superfine powder and its application in tobacco sheet

technical field

The invention relates to the field of cigarette essence and fragrance, in particular to a preparation method of natural fragrance superfine powder and the application of the natural fragrance superfine powder in paper-making tobacco sheet.

Background technique

Ultrafine crushing technology refers to the use of various special crushing equipment to grind, impact, shear, etc. the materials through a certain processing process, so as to crush the material particles above 3mm into fine particles of 5-15μm. As a high-tech processing method, although superfine grinding has been around for a short time, it has been widely used in food, health care products, medicine and other fields. Due to the development of the particles in the direction of micronization, the surface area and porosity of the material are greatly increased, so the ultrafine powder has unique physical and chemical properties, such as good solubility, dispersibility, and adsorption. Spices can be instantly crushed into ultra-fine particles with uniform particle size and good fluidity at low temperature by using ultra-fine pulverization technology. The loss of flavor components of raw materials is less, and the product has a strong and pure aroma, and it belongs to pure physical technology processing, which can guarantee of pure natural properties.

Papermaking Tobacco Sheet is a regenerated product formed by processing and reconstituting tobacco leaves with tobacco leaf fragments, tobacco powder, tobacco stems, etc. as raw materials. The use of paper-making tobacco sheet can not only maximize the utilization rate of tobacco raw materials and reduce the production cost of cigarettes, but also reasonably regulate the physical properties and chemical components of cigarettes to a certain extent, and effectively improve the internal quality of cigarettes. The industrialized production of paper-making tobacco flakes in China began in the late 1990s. At present, in terms of sensory quality, there are generally shortcomings such as obvious miscellaneous gas, insufficient aroma, large irritation, and heavy residue. Those skilled in the art have found that in addition to improving production technology and selecting high-quality raw materials, adding flavors and fragrances has become an effective way to improve the internal quality of flakes. At present, the flavors used in flakes are mainly formulated with monomer compounds as the main raw materials. Although they have achieved certain results in covering up miscellaneous gases and improving the taste, their aroma richness is poor, and there is a clear chemical smell, which is different from smoke. The fragrance is uncoordinated, and the boiling point of some essences is not high, so they are easy to volatilize during application. In addition, the safety issues of chemically synthesized flavors and fragrances have become increasingly prominent.

Under the situation that smoking and health problems are attracting more and more attention, natural flavors and fragrances have become an important direction of research on flavor enhancement and moisturizing of Chinese cigarettes. In the technical field of improving the sensory quality of paper-making tobacco sheets, seeking suitable natural flavors and fragrances is gradually favored by tobacco scientific and technological workers. The application fields of solid flavors are mainly concentrated in the food and daily chemical industries, and there are few researches on their application in cigarette products. At present, the domestic superfine pulverization technology is mainly used in the development of medicine, food, and health care products. There is no report on the application of natural spice superfine powder in tobacco flakes.

(2) Superfine pulverization: Put the fine powder of spices obtained in step (1) into a superfine pulverizer, and carry out superfine pulverization under the conditions of a feed rate of 1 to 2 kg/h and a pressure of 0.5 to 1 MPa for 1 to 2 minutes. times, the natural fragrance superfine powder with a particle size of 8-12 μm is obtained.

The preferred technical scheme of the present invention: after the solid natural spice in step (1) is pulverized, pass through a 40-80 mesh screen.

The preferred technical solution of the present invention: the ultrafine pulverizer described in step (2) is an airflow type ultrafine pulverizer with a liquid nitrogen auxiliary protection device, and the ultrafine pulverizer is existing equipment.

Another technical scheme provided by the present invention: the application of the natural spice superfine powder in tobacco sheet is characterized in that: the above-mentioned natural flavor superfine powder is added in the pulp pre-making tank, and the addition amount is 1/2 of the total weight of the pulp in the pulp tank. 0.1-0.5%, stirring evenly; then the paper pulp added with natural flavor micropowder is made and dried to form a fiber sheet base; then the concentrated solution is directly dipped or sprayed on the sheet base, and finally dried and cut Tobacco flakes containing natural flavor superfine powder are prepared.

The special fragrance prepared by the ultrafine pulverization technology of the present invention has the characteristics of fine and uniform particles, better dispersibility and good adsorption, and can well maintain the pure, comfortable and natural flavor of the raw material; the ultrafine powder of natural spices can reach The sub-micron particle size has incomparable advantages in the fineness of processing powder spices. It is applied to the pulp during the production of paper-making flakes, which can effectively ensure the controllability and uniformity of the added amount. Flavors are not easy to scatter from the formed flake base, which can ensure the quality stability of flavored products. At the same time, it can enrich the aroma, coordinate with the smoke, soft and delicate smoke, reduce oral residue, reduce irritation, cover up miscellaneous gas, and enhance the fragrance The fragrance is long-lasting and stable, and is suitable for use as a flavor additive in the perfuming treatment of thin slices.
