Problems solved by technology

However, the conversion ratio between the content of each smoke cyanide precursor substance and the smoke cyanide content is not clear; and the content of different types of cyanide precursor substances in different tobacco leaves is high or low, not overall high or low
Therefore, it is difficult to estimate the amount of cyanide released after combustion by measuring the content of cyanide precursors in tobacco leaves or cut tobacco

Abstract

The invention provides a method for evaluating the content of cyanide capable of being produced after tobacco combustion, and the method comprises the following steps: (1) detecting the content of water-soluble cyanide precursors in tobacco and recording the content as PCN microgram / g, and detecting the content of protein in tobacco and recording the content as P mg / g; (2) the cyanide release amount HCN microgram / g after tobacco combustion is obtained through calculation, the calculation formula is HCN = A + B * PCN-C * P, A, B and C are constants, the value range of A is 500-520, the value range of B is 2.7-2.8, and the value range of C is 5.3-5.5. The method is simple and feasible, the evaluation result is accurate, a new strategy is provided for evaluation of the cigarette smoke cyanide release amount, and the method has important significance for tobacco product quality control.

Description

technical field [0001] The invention belongs to the technical field of tobacco product detection, and relates to a method for evaluating the content of cyanide that can be generated after tobacco is burned. Background technique [0002] The cyanide content in the flue gas is one of the seven indicators of the flue gas hazard index and an important indicator for evaluating the hazard of the flue gas. The content of cyanide in smoke is not only affected by tobacco materials (mainly the effect of filter hole dilution rate and air permeability of cigarette paper), but also by protein, proline, asparagine, organic ammonium, The influence of the content of more than ten chemical components such as nitrate. [0003] Coke control and harm reduction has always been one of the priorities of the tobacco industry. The selective reduction of cyanide release in cigarette smoke can be achieved by designing a reasonable leaf composition and improving the quality of tobacco leaves by using...
