The predecessor of Sanyuan was the Beijing Milk Terminal, which was established in 1956, and was gradually formed by the merger of the original Beijing farms, and has been listed on the Shanghai Stock Exchange in 2003. Sanyuan Group is a wholly state-owned enterprise under the Beijing Municipal Government, in addition to the dairy business, it also owns 50% of McDonald's Beijing and 25% of McDonald's Guangzhou, and McDonald's milk, cheese and other products are supplied by Sanyuan.
 
Sanyuan's dairy business has the advantage of being close to Beijing and North China, where low-temperature dairy products such as yogurt and pasteurized milk are easy to buy and affordable, but are rarely available in other regions. In order to meet the market demand, Sanyuan has also launched a series of Icelandic yogurt, which does not require cold chain preservation, to expand sales.
 
Due to the advantages of transportation and preservation, ambient yogurt has opened up a new market in China, and its category growth rate far exceeds that of low-temperature yogurt. Similar to Ambrosi, Sanyuan room temperature yogurt focuses on exotic yogurt, and has become an important revenue product of Sanyuan with the help of the rapid growth of the room temperature yogurt category.
 
The traditional yogurt of Iceland is called Skyr, and in order to adapt to the cold environment of Northern Europe, mesophilic lactic acid bacteria are mainly used, and it is generally fermented with sticky bacteria. Skoll also uses rennet in the production process to remove whey, and the final form of the product is similar to that of Greek yogurt.
 
Ternary ambient yogurt is an "Icelandic-style" yogurt, modeled after the texture and taste of Skoll yogurt, but the essence is still conventional flavored fermented milk. Icelandic yogurt plain 100g contains 3g of protein, 3.1g of fat, 12g of carbohydrates, and a caloric value of 370kJ. Whey protein concentrate powder is added to Icelandic yogurt to increase the milk protein content, and the texture of the yogurt is adjusted by modifying starch and thickeners such as pectin and agar, so that the taste and viscosity are close to those of traditional skoll.
