Abstract: The palatability is one of the important criteria to measure the success of pet food. Different breeds of pets or the pet at different developmental stages have different palatabilities. Animal factors cannot be ignored in the study of palatability. The special habits of dogs and cats will also affect their palatability choices in food intake，such as differences in the intake of fat，protein and carbohydrates. At present，the conditioned reflex method，the single ? bowl method and the double ? bowl method are commonly used to evaluate the palatability. While evaluating palatability，the conditioned reflex method focuses more on improving the animals’poor feeding habits. The single ? bowl method and the double ?bowl method directly compare the amount of food intake to evaluate the palatability. In recent years，new methods of using electronic devices have also emerged. These electronic devices can monitor a range of biological indicators in feeding animals to assess palatability. This paper summarizes the commonly used palatability evaluation methods for dog and cat pet food and expounds its characteristics，so as to provide a reference for the subsequent research and development of dog and cat pet food.

摘要： 适口性是衡量宠物食品成功与否的重要标准之一。不同品种宠物对同一款宠物食 品适口性不同，同一只宠物生命发育阶段的变化对同一款宠物食品适口性也可能不同，动物 因素是研究适口性不可忽略的因素。犬猫特殊的习性也会影响其在采食上的适口性选择，例 如在摄取脂肪、蛋白质和碳水化合物的侧重差异。目前，适口性评估方法一般采用条件反射 法、单碗法和双碗法。条件反射法在评估适口性的同时，更侧重改善动物不良采食习惯，单碗 法和双碗法则是将采食量通过数字化呈现，直观比较采食差异评估适口性。近年来，也出现 了使用电子设备对采食时的动物监测一系列生物学指标以评估适口性的新方法。本文归纳总 结了目前常用的犬、猫宠物食品适口性评估方法并阐述其特点，为后续对犬猫宠物食品的研发 提供参考。
