The present invention relates to a taste-sensitive animal model using the measurement value of a weight change of an animal, and a preparation method therefor. More specifically, it was found that since rodents, like humans, have a palate discriminating bad tastes, the rodents avoid consuming drugs, food and the like having a bitter taste, a hot taste, an astringent taste or the like. That is, when adding, to rodent feed, food or drugs having a bad taste and feeding the feed to the rodents, the rodents avoid eating the feed, thereby reducing in weight. Accordingly, a bad taste sensory test can be carried out instead of a human sensory test by using the principal that the feed consumption and weight of the rodents reduces when adding an ingredient having a bitter taste, a hot taste, an astringent taste or the like to rodent feed and feeding the same to the rodents. The purpose of the present invention is to provide: a method for quantitatively evaluating taste, capable of replacing, through the feeding of the feed to rodents, a human sensory test for discriminating bad tastes by humans a preparation method therefor and a sensory test method for the tastes of a drug, food, a dietary supplement, a functional food, a food additive, a medicinal product additive and the like by using an animal.La présente invention concerne un modèle animal sensible du goût employant la valeur de mesure dun changement de poids dun animal et un procédé de préparation associé. Plus spécifiquement, il a été découvert que, étant donné que les rongeurs, comme les êtres humains, ont palais discriminant les mauvais goûts, les rongeurs évitent de consommer des médicaments, des aliments et des produits similaires ayant un goût amer, un goût piquant, un goût astringent ou un goût similaire. Ainsi, lorsquon ajoute à des aliments pour rongeurs des produits alimentaires ou des médicaments ayant mauvais goût et que lon nourrit les rongeurs avec ces aliments, les rongeurs évitent de manger les aliments,
