Abstract

Abstract A process for manufacturing a reconstituted tobacco composition wherein a foamed slurry is created from tobacco, a foaming agent or adhesive and ethylhydroxyethyl cellulose having an ethoxyl D.S. of 1.2 to 1.6 and a hydroxyethyl M.S. of 0.5 to 1.2. The foamed slurry is shaped while maintaining the temperature thereof below the gelatin temperature of the ethylhydroxyethyl cellulose and dried to form a shaped sheet or rod of predetermined moisture content. The foaming agent employed may be a synthetic or natural gum or water dispersible protein.

Claim 1
Independent Claim 238 words
The process of manufacturinG a smokable product comprising creating a foamed slurry from tobacco particles, water, 0.3 percent to 2.5 percent by weight of nonsolvent ingredients of ethylhydroxyethyl cellulose with an ethoxyl D.S. of 1.2 to 1.6 and a hydroxyethyl M.S. of 0.5 to 1.2 and a foaming agent in amounts between 3 percent and 15 percent by weight of the nonsolvent ingredients and selected from natural or synthetic hydrophylic gums in which the natural gums are selected from carbohydrate classes including the animal gums such as glycogen, plant gums and their derivatives, such as cellulose ethers, cellulose esters, starches, starch ethers, starch esters, amylose, amylopectin and their ester and ether derivatives, locust bean gum, guar gum, gum arabic and related seed gums and plant exudate gums, marine plant gums, such as algins, carrageenans laminarins and agar, and microbial gums such as the dextrans, phosphomannans such as the USDA B-1459 and B-1428, and the gluconic acid microbial containing gums such as the USDA Y-1409 gums, and protein classes including water dispersible proteins such as animal proteins such as hydrolyzed keratins, egg albumin, and vegetable proteins such as gluten, and the synthetic gums are selected from the group consisting of polyvinyl alcohol, polyoxyethylene and polyacrylamide shaping said foamed slurry while maintaining the temperature thereof below the gelation temperature of said ethylhydroxyethyl cellulose and subsequently drying said slurry to a shaped sheet or rod form of a predetermined moisture content.
