The tobacco leftovers are porous bodies with capillaries, and contain cellulose, hemicellulose, lignin, pectin, protein and other components. The pyrolysis of these substances can generate more low-grade aldehydes, which can generate irritating cough during smoking, the pyrolysis of lignin can generate catechol and alkyl phenol to cause astringent taste and have cancer promotion activity, and the decomposition of pectin can generate methanol. After the tobacco leftovers are subjected to enzymolysis treatment by plant hydrolase and protease and are extracted by ethanol, cellulose, hemicellulose, lignin, pectin, protein and other components can be degraded into water-soluble sugar, so that uncomfortable feeling generated when the tobacco leftovers are prepared into tobacco particles and used for smoking of tobacco products is avoided.
