Sanyuan Food is a special supplier of dairy products for major political, economic and cultural activities of the central government and Beijing such as the "National People's Congress", "CPPCC", and the Two Sessions, and was listed on the Shanghai Stock Exchange in 2001. With the support of the Ministry of Science and Technology of the People's Republic of China and the Beijing Municipal Science and Technology Commission, Sanyuan Milk Powder is a subsidiary of Sanyuan Food, which has established the "National Maternal and Infant Milk Health Engineering Technology Research Center".
 
Sanyuan infant milk powder uses the milk source of its exclusive domestic pasture and is produced by wet process, although there are many milk powder series, but the quality advantage is lackluster. Judging from a period of milk powder, the gold Ailiyou is positioned at the highest end, with the addition of OPO structural fat, and the price of 400g canned is as high as 208 yuan, which is cost-effective; The 900g canned price of Ailiyou, which is added with casein phosphopeptide and lactoferrin, is 258 yuan, and the price of the same specification is 278 yuan. Ai Yucong is the lowest-priced series of Sanyuan, with a 900g canned price of 138 yuan. In addition to the above 4 series, Sanyuan also has a number of series to choose from, such as Shushi Ailiyou, Aixinbao, Jinbao Aixinbao, Enbeihui, Enbeirui, Enbeiyi, etc., but its DHA content is low as a whole, and it lacks sufficient competitiveness in products at the same price.
