Abstract:Prunus cerasifera Ehrh. exhibits a delightful sweet-sour flavor and is rich in organic acids， natural pigments， pectin， vitamins， and trace elements， as well as polyphenols， active pigments， and complete nutritional amino acids. These functional components demonstrate its promising potential for the development of functional food products. Based on this， this paper analyzed the functional components of wild sour plum and discussed its application advances in the functional food industry， so as to provide a further theoretical basis for the development and utilization of related products of wild sour plum.
