EXTRACTION AND THERMAL DEGRADATION OF CAFFEINE EXTRACTED FROM COLA NUT
ABSTRACT
Caffeine is an odorless, slightly bitter organic compound found mostly in beverages such as coffee or tea and in chocolate. It is the most widely used “mind-altering drug” in the world, though it is considered safe and is mostly unregulated. Caffeine acts as a mild stimulant on the nervous system, aiding in alertness. Caffeine is also included in many weight loss supplements due to its reputation of acting as an appetite suppressant and in stimulating thermo genesis.
A number of over the counter pain relievers, headache remedies and antihistamines contain caffeine.
