Abstract

The invention discloses a crosslinking chemical modifying method of enhancer konjac glucomannan for producing a tobacco sheet. The method comprises the steps of firstly, dissolving konjac glucomannan flavor powder in distilled water to be prepared into a 0.05-0.3% konjac glucomannan water solution; adjusting until the pH is 7.5-9.5; stirring and adding sodium hexametaphosphate solution at the water bath temperature of 50-70 DEG C, so that the mass concentration of sodium hexametaphosphate in a system is 0.02-0.06%; and reacting for 40-70 minutes, cooling and placing for more than 12 hours to obtain the modified konjac glucomannan enhancer solution. The konjac glucomannan solution obtained by the method is added to the production process of the tobacco sheet according to ratio, so that the strength of the tobacco sheet can be effectively improved, and the reinforcing effect is significant.

Description

technical field [0001] The invention relates to konjac gum, in particular to a cross-linking chemical modification method of konjac gum, an enhancer used in the production of tobacco flakes. The modified konjac gum solution is added in proportion to the production process of tobacco flakes, so that the strength of tobacco flakes can be effectively improved. , the enhancement effect is very obvious. Background technique [0002] At the end of the 1970s, as people paid more attention to the safety of smoking, foreign tobacco manufacturers began to systematically study the papermaking sheet technology, and carried out a large-scale promotion and application in the 1980s. At present, it is mainly used in the United States, Western Europe and the United States. Japan and other countries regard it as an effective means to reduce the tar amount of cigarette products. At present, the world uses more than 330,000 tons of reconstituted tobacco products every year, and the application...
