The invention provides a tobacco leaf cutting method, which comprises the following steps: selecting two samples; performing nine-knife and ten-segment horizontal slitting and "nine-square" slitting on the two samples; The content and total amount of aroma substances, the content and coordination index of conventional chemical components, and the scores of sensory quality indicators were analyzed by variance analysis and multiple comparison; Multiple comparisons; according to the comprehensive quality scores of the leaves of each location in the nine-knife-ten-segment-sliced samples, determine the cluster analysis plan; according to the results of variance analysis, multiple comparisons and cluster analysis, get the different locations of the two samples. The change and distribution of tobacco leaf quality were compared, analyzed and counted, and the change rule of tobacco leaf quality was obtained, and the cutting method was formulated according to the change rule. The invention can effectively retain leaves with better quality and improve the comprehensive quality of tobacco raw materials. |
