Abstract: Goat milk has a high nutritional value, is rich in protein, fat, sugar, vitamins and mineral components. It has various functional properties such as easy digestion, hypoallergenicity, intestinal improvement, cholesterol reduction and antioxidant effect, which is the closest to breast milk. In order to promote the research and development of goat milk as a potential substitute for human milk, this paper compares the composition and content of nutrients in goat milk, cow milk and breast milk, and explains the theoretical basis for and feasibility of using goat milk as a substitute for breast milk. Besides, the functional properties and separation techniques of the main bioactive substances (whey protein, casein and oligosaccharides) in goat milk are reviewed, which can provide a scientific basis for the promotion of goat milk as a replacement for breastfeeding and for its application in infant formula milk powder.

Key words: humanized goat milk; whey protein; casein; oligosaccharide; separation technology
