Evaluation method for tobacco shred quality stability of finished cigarette

The invention relates to a finished cigarette cut tobacco quality stability evaluation method, and belongs to the technical field of cut tobacco quality evaluation. The evaluation method comprises the following steps: measuring tobacco shred chemical component indexes of corresponding tobacco shred batches of finished cigarettes in a to-be-evaluated batch, and calculating tobacco shred quality stability indexes C1 and relative standard deviation sigma of the corresponding tobacco shred batches of the finished cigarettes in the to-be-evaluated batch according to a tobacco shred quality stability index model; the C1 is compared with a standard tobacco shred stability index C0, if the absolute value of C1-C0 does not exceed alpha, the quality of the finished cigarette tobacco shreds of the to-be-evaluated batch is stable, and if the absolute value of C0-C1 exceeds alpha, the quality stability of the finished cigarette tobacco shreds of the to-be-evaluated batch is abnormal; 2sigma < = alpha < = 3sigma.
