2, carbonated drinks (Sodas) production began in the late 18th century to the early 19th century. The initial discovery began with the drinking of naturally gushing carbonated spring water. That is, the predecessor of carbonated beverages is natural mineral water. Research on mineral water began in Italy in the mid-15th century, and mineral water was first used for therapeutic purposes. Later, it was proved that artificially mixing water and carbon dioxide gas with natural mineral water containing carbon dioxide gas has a special flavor, which greatly promoted the manufacture of carbonated beverages and the research process. 1772 British Priestley invented the equipment for manufacturing carbonated saturated water, and became the originator of the manufacture of carbonated beverages. He not only studied the carbonation of water, but also studied the carbonation of wine and beer. He noted that the carbonation of water produced a pleasant flavor that escaped along with the aromas of other ingredients in the water. He also emphasized the medical value of carbonated water. 1807, the United States introduced fruit juice carbonated water, carbonated water in the addition of fruit juice to flavor, this product was welcomed, as a start to industrial production. Later, with the synthesis of artificial flavors, liquid carbon dioxide made of cap-shaped cork and the invention of the crown cover, the emergence of mechanized soda production line, so that the carbonated beverages first in Europe, the United States and the United States home industrial production and soon developed to the world.
