Founded in 1953, Weiquan is a large-scale food company that also produces and sells a variety of food products such as condiments, beverages, and biscuits in Taiwan. In 1998, Tingxin Group acquired Weiquan and owned the right to use the trademark "Weiquan" in Asia.
 
Weiquan entered the mainland market in 2002 and established Hangzhou Weiquan Food Co., Ltd., which is mainly engaged in refrigerated beverage business, including active lactic acid bacteria drinks, Benason's milk tea, daily C juice, yogurt yogurt, etc.
 
Weiquan claims to cater to the needs of consumption upgrades and focuses on the health drink market, but most of its products, including lactic acid bacteria drinks, are soft drinks with high added sugar. The food industry recognizes that about 10% of the sugar content can achieve the most suitable sweetness, and the amount of sugar added to lactic acid bacteria drinks is usually higher in order to balance the sour taste, and the same is true for Weiquan lactic acid bacteria drinks, which has a sugar content of not less than 14g/100ml in each product, which is no different from other brands and sugary drinks, and is not "healthy".
 
The fully active lactic acid bacteria drink is also a long-fermented product, and the beverage is slightly brown. Like other brands of the same type, it also features a unique active lactic acid bacteria, using Chr. Hansen casei in Denmark, which claims to contain 60 billion live bacteria per 100 ml. In the evaluation of the Shenzhen Consumer Council, Weiquan did reach the nominal value, containing 2 billion CFU/ml active lactic acid bacteria. However, as mentioned earlier, even if they contain "huge" amounts of lactic acid bacteria, such products are unlikely to improve intestinal health, let alone immunity.
 
The packaging of Weiquan is often changed according to popular factors, such as the once popular "spelling alphabet bottle". In 2019, Weiquan launched a winter limited edition package, but the product formula remains the same. The new model is available in 100ml, 435ml and 900ml packages, and is available in four flavors: original, mango, watermelon and strawberry. Compared with other brands, Weiquan has a medium price, with its 435ml pack priced at 6.8 yuan.
