Sour plum soup is not technology. Kangshifu Sour Plum Soup is a traditional beverage in China with a long history and cultural background. It is made of dried plums, rock sugar, longan pulp and other raw materials by boiling and cooling. The main components are organic acids and various nutrients contained in dried prunes, as well as auxiliary sugars and vitamins such as rock sugar and longan pulp. People can control the production, packaging and sales of sour plum soup through modern scientific and technological means, but sour plum soup itself is undoubtedly a traditional drink.
