Recent advances in the optimization of the sensory attributes of fried foods: Appearance, flavor, and texture

The golden color, crispy texture, and desirable aroma that consumers find desirable are crucial factors contributing to the popularity of fried foods. However, the instability and inconsistency of sensory qualities of industrial fried foods have always been difficult problems for the fried food industry, which has seriously affected the sales and industrialization process of fried foods. Therefore, it is necessary to clarify the formation mechanism and find optimizing methods for the sensory attributes of fried foods. This article reviewed the methods to optimize the three main sensory attributes of fried foods: appearance, flavor, and texture. Initially, the underlying mechanisms responsible for the formation of the sensory attributes of fried foods are reviewed. The factors influencing these processes, as well as the methods developed for controlling them, are then highlighted. This knowledge can then be used to optimize the production of fried foods with both good sensory and nutritional properties. The quality, safety, and nutritional profile of fried foods can be enhanced by gaining a better understanding of the factors that impact their physical and chemical properties during the cooking process. These factors can then be controlled to improve the sensory attributes of fried foods. Nevertheless, it is still a challenge to produce fried foods with good sensory attributes while also ensuring their safety and nutritional property, and more research is needed in this area.
