3 - - Method measuring sensory preference using a Preference-difference test based on combination of 3-point preference test and same-different discrimination test

摘要

The present invention comprises a first step of dividing surveyors into randomly the same number of groups 1, 2, 3 and 4; The group 1 is subjected to the same-to-same test after the preference preference test, the same-non-identical test, the 3-point preference test and the 3-point preference test, and the group 2 performs the same preference test, The same 3-point preference test after the same-to-same test and the 3-point preference test after the same-non-identical test are sequentially performed. Sequentially performing the same-to-same test, the same-non-identical test, the three-point preference test and the advantage preference test sequentially after the three-point preference test; Based on the Thurstonian modeling / signal detection theory (SDT) as a theoretical sensory / preference measurement model to analyze the same-to-same test and the 3-point preference test in the second stepD 'A third step of deriving an estimate; AndD 'And a fourth step of comparing and analyzing the sensory difference discrimination power and the emotional preference using the estimated value, and providing the test method in which the three-point preference test and the same-to-same test are combined. Provides a method for measuring the emotional preference of foods that incorporate the same-to-same test as the point preference test.;
