Method for reducing content of reducing sugar in reconstituted tobacco

Abstract

The invention relates to the field of reconstituted tobacco preparation, in particular to a method for reducing the content of reducing sugar in reconstituted tobacco, and an application of the method. The method comprises the following steps: adding a mixture material of tobacco stems, tobacco waste and tobacco pieces into hot water of 60-70 DEG C, keeping the temperature, performing solid-liquid separation, and preparing to obtain a tobacco extract liquid; respectively adding EDTA (Ethylene Diamine Tetraacetic Acid), proline, lysine, diammonium hydrogen phosphate and a catalyst into the obtained extract liquid, adjusting the pH value of the reaction liquid till the reaction liquid is faintly acid, stirring for more than 2 hours at the constant temperature of 70-80 DEG C, subsequently performing vacuum concentration, and uniformly applying the concentrated extract liquid onto the front and back sides of a paper substrate; putting the obtained product into a baking oven for baking under the condition of ventilation till the moisture content is 11.5-13.5%, and obtaining a finished reconstituted tobacco product. Compared with that of a thin piece which is not treated by using the technical method, the content of the reducing sugar is reduced by 10-20% on premise that the sensory quality of the product is not affected.

Description

Technical field [0001] The invention relates to the field of reconstituted tobacco preparation, in particular to a method for reducing the content of reducing sugars in reconstituted tobacco leaves and uses thereof. Background technique [0002] Reconstituted tobacco, also known as reconstituted tobacco, uses tobacco stems, tobacco dust, tobacco slices, etc. as raw materials to make flakes close to tobacco leaves. It can be used as a raw material for tobacco products to replace natural cigar wrappers. It is now widely used as a raw material for cigarettes. It is an important part of cigarette shreds, and its physical properties and chemical composition can be adjusted as required. Therefore, the application of reconstituted tobacco can help improve the quality of cigarette products, and play an important role in reducing cigarette tar content, improving filling capacity, and reducing costs. . Research on the preparation method of reconstituted tobacco with stable quality, good t...

Problems solved by technology

If the sugar content is too high, the taste of the smoke will be flat, the concentration will be insufficient, the strength and strength will be weakened, and it will also have a negative impact on the combustibility, making the smoldering property worse, the combustion will be incomplete, and the amount of tar produced will increase.

[0004] During the production process of reconstituted tobacco leaves, most of the water-soluble sugars in the raw materials (including tobacco stems, tobacco dust, and chips) are extracted into the extract, and the content of reducing sugar in the extract is about 2%. The content of reducing sugar in the cloth liquid can be as high as 7-10%. Applying the concentrated coating liquid directly and evenly on the reconstituted tobacco paper base usually results in high sugar content in the produced reconstituted tobacco, which affects the taste and color of the reconstituted tobacco. , and tar content, affecting the quality and stability of the product
