  • Patent number: 11860102
    Abstract: To quickly and accurately quantify four types of TSNAs contained in a tobacco raw material by using fluorescence fingerprint information, a tobacco raw material containing known quantities of four types of TSNAs is prepared, and fluorescence fingerprint information thereof is acquired. The fluorescence fingerprint information is pre-processed, as needed, and an estimation model (calibration curve) for estimating the total quantity of the four types of TSNAs from the fluorescence fingerprint information is created. After verifying the calibration curve, the total quantity of the four types of TSNAs contained in an unknown tobacco raw material is estimated by applying the calibration curve to the unknown tobacco raw material. On the basis of the estimated value of the total quantity of the four types of TSNAs and the known abundance ratios of the individual TSNAs, the contained quantities of the four types of TSNAs are estimated.

  • Patent number: 11861151
    Abstract: The relationship between the smell or taste of an object and the expression of the smell or taste can be grasped, and the user can grasp what smell or taste they prefer. In the single-sample display mode, a system displays a group of expressions relating to the olfactory sense stimulated by a sample, and if any expression is selected by the user, the system displays a relationship image indicating the relationship between the selected expression and other samples corresponding to the olfactory sense associated with the expression. In addition, in the multiple-sample display mode, the system displays, for each of plural samples, a group of expressions relating to the sense of smell stimulated by each sample, and displays an expression common to plural samples among the group of expressions.
