Abstract
Pet foods are a vital component of the global food industry. Pet food’s success depends on its acceptance by both consumers (the pets) and purchasers (the pet owners). Palatability tests using panels of both trained and untrained pets are often used to measure the preference and acceptability of pet foods. Human perception of pet foods is usually determined by descriptive sensory analysis. Since dry pet foods (also known as kibbles), while being the most popular, are the least palatable, palatants as a flavor enhancer are generally added to dry pet foods to increase their acceptability to pets. Pet foods can also be prepared to be more appealing to pet owners if the chosen aromas and flavors are commonly associated with human food. With increasing demand, developing flavor enhancers to meet the needs of both pets and owners is becoming increasingly important. This review summarized the current state of flavor enhancers used in the pet food industry and their influence on food palatability from both animal and human standpoints.

IntroductionPet foods are generally available in three forms: moist, semi-moist, and dry, depending on their final moisture content [3]
Impact on Palatability: A Review.The pet food industry is an expanding part of the food industry that is experiencing significant growth and has great potential for continual growth
The results revealed that the use of a traditional liquid palatability enhancer along with liquid aroma used with dry pet foods increased palatability among pets and pet owners
Summary
Pet foods are generally available in three forms: moist, semi-moist, and dry, depending on their final moisture content [3]. In a study by Delime et al [14], American and French pet owners could discriminate the dog and cat dry kibbles by emotions evoked by their odors. The pet food industry is continually exploring ways to decrease objectional odors capable of being detected by pet owners while increasing desirable flavor characteristics from a pet’s perspective. This review focuses on two points: 1) palatability of dry pet foods from the consumer (pet) and purchaser (pet owner) standpoints and 2) flavor enhancers used as palatants in the pet food industry, especially in the category of dry dog foods or kibble, and their impact on palatability
