Description

A method for preparing functional reconstituted tobacco leaves with apple pomace

technical field

The invention relates to the technical field of reconstituted tobacco leaves, in particular to a method for preparing functional reconstituted tobacco leaves with apple pomace.

Background technique

Reconstituted tobacco leaves are tobacco flakes, also known as reconstituted tobacco leaves and homogeneous tobacco leaves. Adding an appropriate amount of reconstituted tobacco into cigarettes can save tobacco raw materials to the greatest extent, effectively reduce the cost of cigarettes, and change the physical and chemical properties of cigarettes to a certain extent. It has become the main method of producing reconstituted tobacco at home and abroad. Due to the advantages of low density, high filling value, high silk yield, good mechanical processing performance and good controllability, papermaking reconstituted tobacco has become an important raw material for modern cigarette formula design and product transformation. In the current production status of domestic paper-making reconstituted tobacco leaves, most of the tobacco stems can provide limited fiber strength, and wood pulp fiber has become a commonly used additive in the production of paper-making reconstituted tobacco leaves because of its good elasticity and strength. When the fiber is burned, it is easy to produce the negative effect of woody gas, which has the disadvantages of high sensory irritation, heavy woody gas, and poor aroma. In addition, papermaking reconstituted tobacco leaves are highly dependent on wood pulp fibers during the papermaking process, which consumes a large amount of wood resources.

In recent years, the development and progress of domestic papermaking reconstituted tobacco production and processing technology is very rapid. Among them, many scholars and experts have conducted research on the application of non-tobacco plants in reconstituted tobacco leaves: for example, the Chinese patent publication with application number 2014105533996 (application date: 2014.10.17, announcement number: CN104223346A, announcement date: 2016.8.24) A method for preparing functional tobacco sheets from tangerine grass, using tangerine grass instead of wood pulp fibers, so that the reconstituted tobacco leaves have an orange aroma; the application number is 2011100200381 (application date: 2011.1.18, announcement number: CN102138701A, announcement date: 2013.3. 1) The Chinese patent discloses the application of turmeric in cigarette production and the method for preparing turmeric tobacco sheet. The turmeric plant contains natural, important heterocyclic aroma substances needed in tobacco, which will give cigarettes Provide a coordinated aroma and stimulate the sweetness of the smoke; the Chinese patent application number 2014100190345 (application date: 2014.1.14, announcement number: CN103783650A, announcement date: 2016.3.30) discloses the application of stevia in the preparation of tobacco flakes , using stevia extract or stevia fiber to prepare tobacco flakes, endow tobacco flakes with special aroma; a Chinese patent with application number 2008100471038 (application date: 2008.3.20, announcement number: CN101536811A, announcement date: 2011.12.7) discloses a The application method of non-tobacco raw material lotus leaf in papermaking thin sheet, the tobacco sheet is prepared by adding lotus leaf in a certain proportion to tobacco powder, mixing and extracting, which can alleviate the shortage of tobacco raw materials and improve the hygroscopicity of tobacco sheet.

However, at present, the preparation of reconstituted tobacco leaves with pomace as a raw material, especially the research on adding them to cigarettes in the form of thin slices has not been reported. Brand new technology.

The reconstituted tobacco leaves prepared in Examples 1-4 were compared with the reconstituted tobacco leaves normally added with 15% wood pulp and the reconstituted tobacco leaves without adding any external fiber for paper tensile strength and smoking evaluation. The results are shown in Table 1 and Table 2.

(1) The physical properties of reconstituted tobacco leaves with different ratios of raw materials, the results are shown in Table 1 below.

Table 1 Physical properties of reconstituted tobacco leaves with different ratios of raw materials

As shown in Table 1: after measuring the reconstituted tobacco leaves prepared in the examples, after adding 12% to 35% pomace fiber, the product cost is reduced and the process is not flawed, and its physical and chemical indicators are in line with YC/T16-2014 (reconstituted tobacco leaves )Require.

(2) Smoking test: the prepared reconstituted tobacco leaves were cut into shreds, and were balanced under constant temperature and humidity conditions for 24 hours to make cigarettes as a sample group, and cigarettes made from reconstituted tobacco leaves without pomace were used as a control group. They are randomly numbered, and the sensory evaluation is carried out by the smoking evaluation team.

(3) Effect evaluation: the evaluation results are shown in Table 2 below.

Table 2 Evaluation Results

From the sensory evaluation results in Table 2: Compared with the reconstituted tobacco leaves with added pomace pulp and wood pulp, there is a significant difference. The reconstituted tobacco leaves prepared with pomace have the characteristics of apple aroma, obvious fruity aroma, and irritating and woody. The bad breath is relatively small. Compared with the fully reconstituted tobacco leaves without adding any external fiber, the difference is not obvious, and it does not affect the comfort and overall coordination of the cigarette aroma. The pomace fiber can be used as a raw material for further development of functional sheets.

For the pomace raw material used in the present invention, considering the actual demand of industrial production, it is best to select air-dried pomace raw material to facilitate large-scale production. In addition, the pomace adopts the method of grinding and dispersing in stages, lightly dispersing it to make it fully dispersed, and separating single fibers of different lengths, so as to form more space frames when the product is formed, improve the internal quality, and make the product quality even better. one chip.

Compared with the fiber raw materials used in the prior art, apple pomace is rich in various nutrients such as protein, soluble sugars, amino acids, cellulose, lipids, polyphenols, flavonoids and minerals, and its edibility makes it The harmful components produced during burning are much lower than that of tobacco leaves, and it has a special fragrance of fragrance and sweetness. The woodiness is relatively small, the taste is softer, and the fruity aroma is obvious. This is an advantage that other raw materials cannot have.

The fruity-flavored reconstituted tobacco leaves produced by the preparation method of the present invention are easy to regulate and control the main chemical indicators such as water-soluble sugar, nicotine and chloride ions, and increase the control means for the chemical components of the reconstituted tobacco leaves, which is beneficial to the batch quality of reconstituted tobacco leaves in production Therefore, compared with the current domestic reconstituted tobacco leaves with more wood pulp, the quality is better, the cost is lower, and the profit margin is larger. It will definitely bring good economic benefits and broad application prospects in the market competition.

The equipment used in the method of the invention can all adopt the prior art, the operation is simple, the sources of raw materials are wide, the production practice is easy, and the method is suitable for industrialized production.
