Abstract:Protein is one of the important indicators to measure the quality of goat milk.Goat milk protein is characterized by high nutrition，low allergenicity，and easy digestion and absorption.Moreover，it has many biological activities，such as antioxidant，antibacterial，and antiviral activities，thus demonstrating a broad application prospect.At present，the immature comprehensive utilization of goat milk protein restricts the healthy and rapid development of the goat milk industry to a certain extent.Therefore，the composition and nutritional properties of goat milk protein were summarized，and the research progress in the biological activities of goat milk protein was reviewed，with a view to providing a reference for the comprehensive utilization of goat milk protein and the development of functional goat milk products.
