The invention discloses a quantitative evaluation method for the easy-to-cure property of flue-cured tobacco. The quantitative evaluation method comprises the following steps: loading fresh tobacco leaves which are normally ripe in different qualities into an electrothermal type humiture self-controlled tobacco curing box at the density of 70kg/m<-3> and curing the fresh tobacco leaves according to a three-segment curing process; judging the easy-to-cure property of the tobacco leaves according to the ratio of carotenoid and chlorophyll in the last stage of yellowing during tobacco curing, wherein the judgment conditions are as follows: when the ratio of carotenoid and chlorophyll at the upper parts and the lower parts of leaves is more than 1.50, and the ratio of carotenoid and chlorophyll of the middle parts of the leaves is more than 2.30, the easy-to-cure property of the flue-cured tobacco leaves is relatively good; when the ratio of carotenoid and chlorophyll at the upper parts and the lower parts of leaves is 1.00-1.50 and the ratio of carotenoid and chlorophyll of the middle parts of the leaves is 2.00-2.30, the easy-to-cure property of the flue-cured tobacco leaves is medium; and when the ratio of carotenoid and chlorophyll at the upper parts and the lower parts of leaves is less than 1.00, and the ratio of carotenoid and chlorophyll of the middle parts of the leaves is less than 2.00, the easy-to-cure property of the flue-cured tobacco leaves is relatively bad. The quantitative evaluation method utilizes the relationship between the activity of polyphenol oxidase and the curing quality of tobacco leaves to evaluate the curing resistance of the tobacco leaves, is high in accuracy and good in repeatability, and reduces the experience demand on technical personnel.
