Background
Since the 60's of the 20 th century, the beverage industry began mass production and high-speed development, and has now become one of the major mainstay industries in the world today, with diverse beverage varieties. Among these, some dairy-containing beverage products are produced.
There are many types of beverages containing milk systems, such as common milk-containing beverages, and other beverage products incorporating milk and dairy products, which are subject to many problems during production and storage, such as product stability, flavor retention, which is important during product shelf life, and the like. In the case of milk-containing beverages, oxidation of proteins and the like during storage usually occurs to produce a taste which is rancid, and food plants usually add antioxidants to prevent oxidation of proteins, typically vitamin C or E, but experiments have shown that the inhibitory effect of such antioxidants in yoghurt drinks is not very significant.
There is a need for a long-shelf-life yoghurt drink which can maintain the flavor of the product during the shelf life and improve the appreciation period of the product, and a preparation method thereof to solve the technical problems.
