Abstract

A method for papermaking reengineering qualitative alcohol sink tobacco leaf tobacco extract purification processing method was proposed in this study. Tobacco extract was precipited by 95% ethanol after pre-concentration treatment, and then it was centrifuged to remove the impurities, and macromolecular substances without favoring the sensory quality, such as protein and pectin. Moreover, the pre-concentration of solid content was also examined, including the alcohol concentration, alcohol sink factors, and sink time extract, influencing of sensory quality. The results showed that the papermaking method reconstruction tobacco leaf tobacco extract pre-concentration to solid content was 20%, 40% to 95% of the pre-concentrate volume concentration of ethanol, after 60 min under 4 000 r/min speed centrifugal 5 min. With the removal of precipitation concentrated of 40% solid content, tobacco concentrate quality, and the sweet temperament and flue gas concentration increased significantly, while the mixed gas and irritating significantly reduced. Thereore, the overall sensory evaluation was improved two points. Compared wit the formal production technology of tobacco extract without alcohol sink, the removal rate of protein and pectin reached 55.18% and 47.95%, respectively.
