Abstract

The invention discloses a preparation method of reconstituted tobacco leaves with sweetening function. The aromatic vegetable sweet basil (Ocimum basilicum L.) is used as the raw material after the conventional extraction method of aroma components, mixed with tobacco stems and shredded tobacco pieces in proportion, soaked in hot water for extraction; the obtained insoluble matter is made into a substrate by papermaking method ; The obtained water extract is used for coating the above-mentioned substrate after being vacuum-concentrated to obtain reconstituted tobacco leaves. The reconstituted tobacco leaf is applied to the cigarette formula, and has the effect of increasing sweet aroma and enriching the aroma of smoke. According to the method, the residue after the aromatic components are extracted from the spice plants can be reused, the utilization rate of the spice plants is improved, and the production cost is reduced.

Description

A preparation method of reconstituted tobacco leaves with sweetening function

technical field

The invention belongs to the technical field of reconstituted tobacco leaves, and in particular relates to a method for preparing reconstituted tobacco leaves with a sweetening function.

Background technique

In today's cigarette industry, reconstituted tobacco has increasingly become an indispensable raw material in the cigarette industry. It plays a very important role in improving the internal quality of tobacco products, reducing tar content, changing smoke components, saving tobacco consumption, and stabilizing cigarette formula. role.

With the continuous development of reconstituted tobacco technology, the application of non-tobacco plant materials in reconstituted tobacco has also been reported. Yao Ermin et al. used tea as an additive, added reconstituted tobacco leaves with different proportions of tea leaves to the leaf group to make cigarette samples, and the results showed that compared with the control sample, the aroma components in the cigarettes of the reconstituted tobacco leaf groups with different proportions of tea leaves were different. The main harmful components are reduced to varying degrees as the degree increases; Zheng Qin’an et al. introduced a papermaking method for the preparation of reconstituted tobacco leaves containing Chinese herbal medicine components. After the Chinese herbal medicine and tobacco are mixed and extracted, their fibers are used to make paper leaves with high filling value. The extract was concentrated in low-temperature vacuum and then dip-coated on the paper leaves. The reconstituted tobacco leaves fully retained the insoluble effective medicinal ingredients and harmonized with the aroma of the tobacco; Fan Yuntao et al. , and then applied to the cigarette formula, the results show that the iris aroma components can improve the smoke quality of paper-making reconstituted tobacco leaves, and have the effect of reducing irritation, and the paper-making reconstituted tobacco leaves after flavoring have the same effect in cigarettes.

Relevant patents are also reported. Liu Weijuan et al. invented a cigarette flavoring method, flavoring reconstituted tobacco leaves and its preparation method. Fumigation spice plants such as Atractylodes atractylodes, Artemisia argyi and Angelica dahurica were mixed with tobacco raw materials to prepare reconstituted tobacco leaves to achieve cigarette flavoring. Xiang; Yang Weizu et al. invented a non-tobacco papermaking reconstituted tobacco formula and its preparation and use method. The raw materials are composed of fine tea stalks, thick tea stalks and tea powder of black tea or Puer tea. The physical properties of the reconstituted tobacco leaves are Improved, endowed with a special, harmonious aroma.

Although there have been reports on the preparation of functional reconstituted tobacco leaves from non-tobacco plants as raw material components, there have been no reports on the preparation of reconstituted tobacco leaves from the residue left after extraction of conventional aroma components from the spice plant sweet basil.

Contents of the invention

The object of the present invention is to address the deficiencies of the prior art, and provide a reconstituted tobacco leaf with a sweetening function prepared from the residue after sweet basil extraction.

The purpose of the present invention is achieved through the following technical solutions.

* Unless otherwise specified, the percentages used in the present invention are all mass percentages.

A reconstituted tobacco leaf with a sweetening function is prepared by the following method:

(1) Weigh each raw material according to the following parts by weight for later use: 50-60 parts of tobacco stems, 30-40 parts of tobacco fragments, and 10-20 parts of sweet basil treatment, and the sweet basil treatment is sweet basil conventionally prepared The residue after the extraction method of aroma components is used;

(2) After mixing sweet basil treatment, tobacco stems and tobacco fragments, extract them with water at 60-80 °C for 30-90 min, and separate the water extract and insoluble matter;

(3) Beat the insoluble matter, and use papermaking technology and equipment to make a substrate;

(4) Vacuum-concentrate the water extract to a density of 1-1.2 g/cm ³ , and backcoat the concentrated solution on the formed substrate to obtain the desired reconstituted tobacco leaf with sweetening function.

Among them, sweet basil (Ocimum basilicum L.) is an annual herbaceous plant of Lamiaceae, and the used part is its aerial part; conventional methods for extracting aroma components include solvent extraction, steam distillation, simultaneous distillation extraction, supercritical CO ₂ extraction, sub- Critical extraction.

The prepared reconstituted tobacco leaves were applied to the leaf group formula according to the design ratio of different brands of cigarettes, and the sample cigarettes were made for smoking evaluation. The results showed that the addition of the reconstituted tobacco leaves had the effect of increasing sweetness and enriching the aroma of cigarettes.

Compared with the prior art, the present invention has the following beneficial effects:

1. The residue left after the aromatic plant sweet basil is used as raw material for the preparation of reconstituted tobacco leaves after being processed by conventional aroma-generating components extraction methods can improve the utilization rate of aromatic plants and reduce the manufacturing cost of reconstituted tobacco leaves;

2. The addition of the reconstituted tobacco leaves in cigarettes has the effect of increasing the sweetness and enriching the aroma of cigarettes;

3. The production process has strong operability and standardization, can realize industrial production, and has good development and application prospects.
