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 se rapporte à un modèle animal sensible à un goût utilisant la valeur de mesure dun changement de poids dun animal, et à son procédé de préparation. De façon plus précise, il a été découvert que, puisque les rongeurs, comme les êtres humains, ont un palais distinguant des mauvais goûts, les rongeurs évitent de consommer des médicaments, des aliments et analogues ayant un goût amer, un goût chaud, un goût astringent ou analogue. Cest-à-dire que, lorsquon ajoute, à la nourriture dun rongeur, des aliments ou des médicaments ayant un mauvais goût et lorsquon donne à manger aux rongeurs, les rongeurs évitent de manger les aliments, ce qui leur permet de perdre du po
