Although the idea never stuck, the term soft drink did. Until the s soft drinks were produced manually, from blowing bottles individually to filling and packaging. During the following two decades automated machinery greatly increased the productivity of soft drink plants. Probably the most important development in bottling technology occurred with the invention of the "crown cap" in , which successfully contained the carbon dioxide gas in glass bottles.

The crown cap design endured for 70 years. The advent of motor vehicles spawned further growth in the soft drink industry. Vending machines, serving soft drinks in cups, became regular fixtures at service stations across the country. In the late s aluminum beverage cans were introduced, equipped with convenient pull-ring tabs and later with stay-on tabs.

Light-weight and break-resistant plastic bottles came into use in the s, though it was not until that the soft drink industry used plastic PET polyethylene terephthalate on a wide scale. Soft drink manufacturers have been quick to respond to consumer preferences. In diet colas were introduced in response to the fashion of thinness for women. In the s the growing health consciousness of the country led to the creation of caffeine-free and low-sodium soft drinks.

The s ushered in clear colas that were colorless, caffeine-free, and preservative-free. Carbon dioxide adds that special sparkle and bite to the beverage and also acts as a mild preservative. Carbon dioxide is an uniquely suitable gas for soft drinks because it is inert, non-toxic, and relatively inexpensive and easy to liquefy. Used in either dry or liquid form, sugar adds sweetness and body to the beverage, enhancing the "mouth-feel," an important component for consumer enjoyment of a soft drink.

Sugar also balances flavors and acids.

Sugar-free soft drinks stemmed from a sugar scarcity during World War II. Soft drink manufacturers turned to high-intensity sweeteners, mainly saccharin, which was phased out in the s when it was declared a potential carcinogen.

Other sugar substitutes were introduced more successfully, notably aspartame, or Nutra-Sweet, which was widely used throughout the s and s for diet soft drinks. Because some high-intensity sweeteners do not provide the desired mouth-feel and aftertaste of sugar, they often are combined with sugar and other sweeteners and flavors to improve the beverage.

The overall flavor of a soft drink depends on an intricate balance of sweetness, tartness, and acidity pH. Acids add a sharpness to the background taste and enhance the thirst-quenching experience by stimulating saliva flow.

The most common acid in soft drinks is citric acid, which has a lemony flavor. Acids also reduce pH levels, mildly preserving the beverage. Very small quantities of other additives enhance taste, mouth-feel, aroma, and appearance of the beverage. There is an endless range of flavorings; they may be natural, natural identical chemically synthesized imitations , or artificial chemically unrelated to natural flavors.

Emulsions are added to soft drinks primarily to enhance "eye appeal" by serving as clouding agents. Emulsions are mixtures of liquids that are generally incompatible.

They consist of water-based elements, such as gums, pectins, and preservatives; and oil-based liquids, such as flavors, colors, and weighing agents. Saponins enhance the foamy head of certain soft drinks, like cream soda and ginger beer.

To impede the growth of microorganisms and prevent deterioration, preservatives are added to soft drinks. Anti-oxidants, such as BHA and ascorbic acid, maintain color and flavor. Beginning in the s, soft drink manufacturers opted for natural additives in response to increasing health concerns of the public. Impurities in the water are removed through a process of coagulation, filtration, and chlorination.

Coagulation involves mixing floc into the water to absorb suspended particles. The water is then poured through a sand filter to remove fine particles of Roc.

To sterilize the water, small amounts of chlorine are added to the water and filtered out. The Manufacturing Process Most soft drinks are made at local bottling and canning companies. Flavors Acids are added to soft drinks for extra bite, and mouth feel. The primary acid used in colas is phosphoric acid , while the one used in citrus flavored drinks is usually citric acid. Carbonated water water that has the gas carbon dioxide dissolved in it under pressure is also mildly acidic it is chemically carbonic acid, H2CO3.

Caffeine is added as a stimulant, but it has a bitter taste that is a component in many soft drinks. These help keep fatty flavors suspended in the liquid density balancers and emulsifiers. Gums and modified food starches are also used for this purpose. Glyceryl abietate is also used in cosmetics, as the waxy substance in eyebrow pencils. Preservatives Sodium benzoate is used as a broad spectrum antimicrobial, inhibiting bacteria, molds, and yeasts.

The high acid content of the soft drink is necessary for the preservative action. In the late s Europeans and Americans began drinking the sparkling mineral water for its reputed therapeutic benefits.

The first imitation mineral water in the U. It was called "soda water" and consisted of water and sodium bicarbonate mixed with acid to add effervescence. Pharmacists in America and Europe experimented with myriad ingredients in the hope of finding new remedies for various ailments.

Already the flavored soda waters were hailed as brain tonics for curing headaches, hangovers, and nervous afflictions. Pharmacies equipped with "soda fountains" featuring the medicinal soda water soon developed into regular meeting places for local populations.

Raw Materials

Flavored soda water gained popularity not only for medicinal benefits but for the refreshing taste as well. The market expanded in the s when soda water was first sold in glass bottles. Filling and capping the gaseous liquid in containers was a difficult process until , when a manual filling and corking machine was successfully designed.

The term "soda pop" originated in the s from the popping sound of escaping gas as a soda bottle was opened. New soda flavors constantly appeared on the market. Some of the more popular flavors were ginger ale, sarsaparilla, root beer, lemon, and other fruit flavors.

In the early s pharmacists experimented with powerful stimulants to add to soda water, including cola nuts and coca leaves.

Soft Drink

They were inspired by Bolivian Indian workers who chewed coca leaves to ward off fatigue and by West African workers who chewed cola nuts as a stimulant. In an Atlanta pharmacist, John Pemberton, took the fateful step of combining coca with cola, thus creating what would become the world's most famous drink, "Coca-Cola".

The beverage was advertised as refreshing as well as therapeutic: Although the name was a derivation of pepsin, an acid that aids digestion, Pepsi did not advertise the beverage as having therapeutic benefits. By the early 20th century, most cola companies focused their advertising on the refreshing aspects of their drinks.

As flavored carbonated beverages gained popularity, manufacturers struggled to find an appropriate name for the drinks. Some suggested "marble water," "syrup water," and "aerated water. Although the idea never stuck, the term soft drink did. Until the s soft drinks were produced manually, from blowing bottles individually to filling and packaging.

In , Macbride in Ireland demonstrated the medicinal uses of effervescent waters and their antiseptic properties. This is achieved by increasing the pressure on the raw side of the membrane and forcing the water across.

The process of obtaining a certificate to operate is lengthy, and only afterwards can the process of certification to natural mineral water status be commenced.

After an introduction to carbonated soft drinks, this volume considers the specifications and treatments for water, the main ingredient of any soft drink. The solubility of CO2 in water decreases as temperature increases but increases with increasing pressure, that is, a given level of carbonation will generate a higher pressure as the temperature increases.
