Carboxymethyl cellulose(CMC)with different degree of substitution(DS)was prepared by controlling feed ratio and times of alkalization and *** with different molecular weight was prepared by degradation of hydrochloric acid *** experiments were designed to study the effects of addition amount,molecular weight and DS of CMC on the tensile strength of tobacco *** effects of CMC on the thermal properties and aerosol release of tobacco sheets were also *** results showed that the addition amount and the molecular weight of CMC had obvious effect on the tensile strength of tobacco *** DS of CMC had no significant effect on the tensile strength of tobacco *** addition of CMC improved the thermal stability of tobacco sheets to a certain extent,and had certain influence on the content of nicotine in aerosol.

[Objectives]This study was conducted to deeply understand the effects of production process on the quality of new types of tobacco sheets with different flavors.[Methods]Based on the pilot production process of thick pulp method,four different flavors of tobacco sheets were sampled at several links in the production process,for the detection of the contents of the main components in the samples,including propylene glycol,glycerol,menthol and glyceryl triacetate,so as to explore the change trends of various components in the thick pulp process.[Results]The change laws of propylene glycol and glycerol contents had a very high similarity,showing a trend of first decreasing and increasing *** changes of menthol content and glyceryl triacetate content were greatly affected by the specific flavor *** one of the indexes of the new tobacco evaluation system,the alcohol-to-ester ratio data need to be further improved in the actual production and application process.[Conclusions]This study provides basic data support for improving the quality of tobacco sheets.
