Soft drink

A soft drink (also called soda, pop, coke[citation needed], soda pop, fizzy drink, or carbonated beverage) is a non-alcoholic beverage that typically contains carbonated water, a sweetening agent, and a flavoring agent. The sweetening agent may be sugar, high-fructose corn syrup, or a sugar substitute(in the case of diet drinks). A soft drink may also contain caffeine or fruit juice. Products such as energy drinks, Kool-Aid, and pure juice are not considered to be soft drinks.

Other beverages not considered to be soft drinks are hot chocolate, hot tea, coffee, milk, milkshakes, and schorle. Soft drinks are called “soft” in contrast to “hard drinks” (alcoholic beverages). Small amounts of alcohol may be present in a soft drink, but the alcohol content must be less than 0.5% of the total volume[1][2] if the drink is to be considered non-alcoholic.[3] Widely sold soft drink flavors are cola, lemon-lime, root beer, orange, grape, vanilla, ginger ale, fruit punch, sparkling lemonade, squash, and flavored water. Soft drinks may be served chilled or at room temperature. They are rarely heated.

Carbonated drinks

Soft drinks displayed on supermarket shelves. In late 18th century, scientists made important progress in replicating naturally carbonated mineral waters. In 1767, Englishman Joseph Priestley first discovered a method of infusing water with carbon dioxide to make carbonated water which has 3.4 mg in the drink [4] when he suspended a bowl of distilled water above a beer vat at a local brewery in Leeds, England. His invention of carbonated water, (also known as soda water), is the major and defining component of most soft drinks.

Priestley found water thus treated had a pleasant taste, and he offered it to friends as a refreshing drink. In 1772, Priestley published a paper entitled Impregnating Water with Fixed Air in which he describes dripping oil of vitriol (or sulfuric acid as it is now called) onto chalk to produce carbon dioxide gas, and encouraging the gas to dissolve into an agitated bowl of water.[5] Another Englishman, John Mervin Nooth, improved Priestley’s design and sold his apparatus for commercial use in pharmacies. Swedish chemistTorbern Bergman invented a generating apparatus that made carbonated water from chalk by the use of sulfuric acid. Bergman’s apparatus allowed imitation mineral water to be produced in large amounts. Swedish chemist Jöns Jacob Berzelius started to add flavors (spices, juices and wine) to carbonated water in the late 18th century.

Soft drink bottling industry Over 1,500 U.S. patents were filed for either a cork, cap, or lid for the carbonated drink bottle tops during the early days of the bottling industry. Carbonated drink bottles are under great pressure from the gas. Inventors were trying to find the best way to prevent the carbon dioxide or bubbles from escaping. In 1892, the “Crown Cork Bottle Seal” was patented by William Painter, a Baltimore, Maryland machine shop operator. It was the first very successful method of keeping the bubbles in the bottle. ]Automatic production of glass bottles

In 1899, the first patent was issued for a glass-blowing machine for the automatic production of glass bottles. Earlier glass bottles had all been hand-blown. Four years later, the new bottle-blowing machine was in operation. It was first operated by the inventor, Michael Owens, an employee of Libby Glass Company. Within a few years, glass bottle production increased from 1,400 bottles a day to about 58,000 bottles a day. Home-Paks and vending machines

During the 1920s, the first “Home-Paks” were invented. “Home-Paks” are the familiar six-pack cartons made from cardboard. Automatic vending machines also began to appear in the 1920s.
