Vitasoy (1940—) is a well-known beverage brand in Hong Kong. The soybean milk beverage has been produced in Hong Kong since 1940, and now its production plants are all over Chinese mainland, Hong Kong, Australia and the United States. Vitasoy is currently managed by Vitasoy International Group Limited (HKEx: 0345), a listed company in Hong Kong, which also uses Vitasoy as its brand name for other beverage products, including fruit juice, milk, tea drinks, soft drinks, distilled water and tofu. Paper-packed vitasoy milk vitasoy milk was developed by the founder, Dr. Luo Guixiang. Luo Guixiang hopes to provide a cheap and protein-rich drink for ordinary families in Hong Kong as a substitute for more expensive milk. Soybean with the title of "Cow of China" is rich in protein and cheap. Luo Xianggui thinks that soybean milk made from soybean can be a substitute for milk, so he developed Vitasoy. Vitasoy soy milk was launched on April 3, 1940. The first Vitasoy factory was located in great george street, Causeway Bay, Hong Kong Island. On the first day, only six bottles of soy milk were sold at a price of HK$ 6 cents. In the early days, Vitasoy was delivered door-to-door by a shop assistant by bicycle. In addition, Vitasoy in the early days was not disinfected and needed to be drunk on the same day, otherwise it would go bad, so it was not welcomed by consumers. Before the war, about1000 bottles were sold every day. During the Japanese occupation, the Vitasoy factory was shut down, and it resumed production after Hong Kong regained its light. In 1950, it was moved to Huangzhukeng, Aberdeen, where it was sold by retailers in addition to daily delivery. Since 1953, Vitasoy milk was sterilized at high temperature, so it was not necessary to be stored in cold storage, and the sales volume began to increase greatly. By the mid-1950s, 1950. When Vitasoy was first introduced, the soy milk was not processed. In 1962,/kloc-0 joined Maijing Vitasoy, and in the same year, a new factory was built in Kwun Tong Industrial Zone, Kowloon. 1987 Tuen Mun Factory in New Territories was completed and became the group headquarters. 1On March 30, 1994, Vitasoy Group was officially listed on the Hong Kong Stock Exchange, and the first day's share price was about 1.5 Hong Kong dollars. In the same year, the factory in Shenzhen, Guangdong, China was officially put into production. 1998, it was put into production in Shanghai and Nasoya plant in Ayre, Massachusetts, USA. In the early days, Vitasoy was sold in wide-mouthed milk bottles, and later it was changed to glass bottles containing soda. 1975 Tetra Pak (Tetrapak) packaging equipment was introduced from Sweden for the first time, and 250 ml of paper packaging was added and sterilized at ultra-high temperature, so that the products could be stored for many months. 1976 Vitasoy launched a series of juice drinks under the brand of "Vitasoy", and then launched lemon tea and chrysanthemum tea in 1979. 1984 introduced a large package of 375 ml, and in 2000, a small package of 125 ml was introduced for the convenience of young children. There are even aluminum cans for sale at present. Because Vitasoy has been flaunting its healthy image when it was launched, it was advertised with the slogan "It's not as simple as soda" (not just soda), or people might wonder why Vitasoy was called soda without steam. This is because in the 1940s and early 1980s, people's knowledge level was generally not high, and at that time, all soft drinks in Hong Kong were collectively called soda. Things have changed, and now no one calls milk drinks soda, so people now can't understand the advertising words at that time. Many schools with strict school rules also make an exception and allow vitasoy milk to be sold in the school canteen. Vitasoy sold in schools is generally packed in glass bottles. In the cold winter, drinking hot Vitasoy sold in the canteen is a childhood memory of many Hong Kong people.
