Abstract: Citrus fiber is a kind of natural dietary fiber extracted from the peel of citrus fruits. It has many physiological functions such as lowering blood sugar, lowering blood lipid and regulating intestinal balance. The internal structure, physicochemical properties and processing properties of citrus fibers from different citrus fruits are different. At present, the commonly used extraction processes include physical, chemical and biological methods. How to improve the yield of the final product has always been a difficulty faced by the citrus industry. Citrus fiber has excellent water-holding capacity (WHC), emulsifying capacity and apparent viscosity, and it is widely used in the processing of dairy products. In addition, citrus fiber plays an irreplaceable role in the development of clean-label dairy products. This paper reviews the physicochemical properties, extraction processes and application in dairy products of citrus fiber, which is of reference significance for the research and application of citrus fiber.
