Method for quickly determining release amount of hydrogen cyanide after tobacco leaves are burnt

The invention belongs to the technical field of cigarette production, and particularly relates to a method for quickly determining the release amount of hydrogen cyanide after tobacco leaves are burnt. The method is a thermal cracking-solvent trapping-flow analysis method and specifically comprises the steps of drying, thermal cracking, solvent trapping, analyzing based on the flow analysis method, calculating and the like. According to the fundamental principle, tobacco leaves are cracked in a cracking instrument, and air serves as the cracking reaction gas; then a headspace bottle filled with a hydrogen cyanide trapping solution is used for absorption, at last, quantitative analysis is conducted on a flow analysis meter, and thus the release amount of hydrogen cyanide in smoke generated after tobacco leaves are burnt can be obtained. According to the method, the release amount of hydrogen cyanide in smoke can be obtained without making tobacco leaves into cigarettes, and thus the advantages of being easy to operate, quick and efficient are achieved. Hence, manpower and material resources can be saved, corresponding detection cost is lowered, working efficiency can be better improved, meanwhile, the method can be well used for improving a cigarette formula, and the smoking quality and safety of tobaccos are improved.
