Problems solved by technology

Natural guar gum has the following disadvantages: high content of water-insoluble matter; not fast swelling and hydration, slow dissolution rate; difficult to control viscosity; poor resistance to electrolytes and microbial degradation. After sexual intercourse, the above shortcomings can be significantly improved
Its shortcoming is that the modified guar gum aqueous solution concentration is low, and its preparation method is difficult to industrialization and mass production, and the cost is higher

Abstract

The invention provides a modified guar gum and a preparation method thereof as well as application in preparation of tobacco sheet. Guar gum raw powder is dispersed in aprotic solvent, modified through basification, cross bonding and cationization and then the modified guar gum is obtained through neutralization, filtration and drying. The product prepared by the invention is prepared into the aqueous solution thereof and then added to the formula of preparing tobacco sheet. The product has obvious retention and reinforcement effect, compared with the preparation method without adding the product, the retention effect can be improved by more than 30 percent.

Description

technical field [0001] The invention relates to a modified guar gum, its preparation method and its application in the preparation of tobacco sheets. Background technique [0002] At present, guar gum and its modified products are mainly used in industries such as cosmetics, petroleum exploration, food, medicine, textile, construction and papermaking. In recent years, especially in the paper industry, the application of modified guar gum has become more and more extensive, and its function has been more and more recognized by people. [0003] Guar gum is a kind of leguminous plant, which is a natural galactomannan, which mainly grows in the arid regions of India and Pakistan. The main chain of its chemical structure is (1,4)-β-D mannose as the unit, and the side The chain is composed of α-D galactose and connected to the main chain by (1,6) bonds. There is a galactose branch every other mannose, and the ratio of the two is about 2:1. Guar gum can be dispersed in water to ...
