Abstract
The present invention relates to a method for providing a reconstituted tobacco material. The method includes contacting tobacco material dispersed in a liquid having an aqueous character with a humectant or binding agent or both under high shear mixing conditions at a temperature of at least about 35.degree. C. to provide a mixture. The mixture is then contacted with a pectin release agent, preferably at a pH of about 5 to about 9, while maintaining the high shear mixing conditions to provide a tobacco material having released tobacco pectins. Preferably, the tobacco material having released tobacco pectins is then formed into a predetermined shape and subjected to conditions sufficient to cause the released tobacco pectins to undergo crosslinking.
Claims33
A method of providing a tobacco material having released tobacco pectins, the method comprising the steps of:
- (a) contacting tobacco material dispersed in a liquid having an aqueous character with a humectant or binding agent or both under high shear mixing conditions at a temperature of at least about 35.degree. C. to provide a mixture and
- (b) contacting the mixture of step (a) with a pectin release agent while maintaining the high shear mixing conditions and a temperature of at least about 35.degree. C. to provide a tobacco material having released tobacco pectins.
A method of providing a tobacco material having released tobacco pectins, the method comprising the steps of:
- (a) contacting tobacco material dispersed in a liquid having an aqueous character with a humectant or binding agent or both under high shear mixing conditions at a temperature of at least about 35.degree. C. to provide a mixture and
- (b) contacting the mixture of step (a) with a pectin release agent while maintaining the high shear mixing conditions and a temperature of at least about 35.degree. C. to provide a tobacco material having released tobacco pectins;
- (c) forming the tobacco material having released tobacco pectins of step (b) into a predetermined shape;
- and
- (d) reducing the moisture content of the formed tobacco material provided in step (c) to cause the released tobacco pectins to undergo crosslinking.
