where does caffeine come from in energy drinks
Caffeine Caffeine is also a common ingredient of soft drinks, such as cola, originally prepared from kola nuts. Soft drinks typically contain 0 to 55 milligrams of caffeine per 12 ounce serving.[181] By contrast, energy drinks, such as Red Bull, can start at 80 milligrams of caffeine per serving. The caffeine in these drinks either originates from the ingredients used or is an additive derived from the product of decaffeination or from chemical synthesis. Guarana, a prime ingredient of energy drinks, contains large amounts of caffeine with small amounts of theobromine and theophylline in a naturally occurring slow-release excipient.[182]
List of coffee chemicals More than 1,000 chemical compounds in coffee,[1] and their molecular and physiological effects, are areas of active research in food chemistry. There are a large number of ways to organize coffee compounds. The major texts in the area variously sort by effects on flavor, physiology, pre- and post-roasting effects, growing and processing effects, botanical variety differences, country of origin differences, and many others. Interactions between compounds also is a frequent area of taxonomy, as are the major organic chemistry categories (Protein, carbohydrate, lipid, etc.). In the field of aroma and flavor alone, Flament gives a list of 300 contributing chemicals in green beans, and over 850 after roasting. He lists 16 major categories to cover those compounds related to aroma and flavor.[2]
