Problems solved by technology

Among them, for the steam distillation method, due to the composition of tobacco stems and tobacco leaves, lignin and cellulose and other negative odor-absorbing substances that affect the taste of smoking are more, and the aroma components are less. The extraction efficiency and extraction effect of tobacco stems are poor, and the aroma components cannot be extracted well, and there are many impurities, which affect the quality of smoking; at the same time, the steam distillation method requires high heating temperature, which will cause heat-sensitive aroma substances to evaporate with water vapor. loss, further resulting in fewer aroma substances, and the aroma is not realistic enough
Although the solvent extraction method has a high yield, its extraction effect is poor. The extract contains a large amount of impurities such as resin and wax, which affects the aroma-producing function of the extract, and then affects the quality of smoking. It must be further refined to make the process become It is very complicated and difficult to achieve large-scale production, and this method has the problem of recycling organic solvents, which has adverse effects on the environment

Abstract

The invention provides a tobacco stem extract, a preparation method of the tobacco stem extract and a tobacco product. The preparation method of the tobacco stem extract comprises the following steps:a) mixing and heating tobacco stems and water to obtain a tobacco stem liquid; mixing and activating a composite enzyme with water, so as to obtain an enzyme dispersion liquid; wherein the compositeenzyme comprises cellulose, pectinase, xylanase, protease, amylase and glucoamylase; b) mixing and heating the tobacco stem liquid and the enzyme dispersion liquid to obtain a reactant; c) carrying out alcohol extraction on the reactant to obtain an extracting solution; and d) and reacting the extracting solution with a composite additive to obtain a tobacco stem extract; wherein the composite additive comprises cellulose, xylose, fructose and vitamin C. According to the invention, the preparation method provided by the invention can effectively remove negative odor absorption substances affecting the smoking taste in tobacco stems. Meanwhile, substance conversion can be promoted, and a large amount of fragrant substances with tobacco baking fragrance are added. The smoking quality of tobacco products is greatly improved.

Description

technical field [0001] The invention relates to the technical field of tobacco, in particular to a tobacco stem extract, a preparation method thereof and tobacco products. Background technique [0002] Tobacco is an annual herbaceous plant of the family Solanaceae, and it is also one of the most widely distributed and planted economic crops in the world. It is mainly used for the production of tobacco products such as cigarettes. Due to its extremely high economic value, the cigarette industry has become an economic pillar industry in many countries. China, on the other hand, grows and consumes the most tobacco in the world every year. As a high-value pastime consumer product, in addition to tobacco raw materials, tobacco flavors and fragrances of various formulations are also indispensable components in the cigarette production process. However, these artificial flavors are easy to produce miscellaneous gas and lack natural feeling, which affects the quality of cigarettes...
