Though every one enjoying having coffee but any one thought about what is the chemistry of coffee that makes us so desirable?
Simple answer for this is coffee beans aroma
The coffee bean is where the chemistry of coffee begins and the aroma is what gives you the kind of flavor that you taste.
Coffee contains huge numbers of compounds, that includes
- ~ 800 - 1000 aroma compounds
- Caffeine
- Carbohydrates
- Chlorogenic acids
- Trigonelline
- Lipids
- Melanoidins
- Volatile compounds
Caffeine [1,3,7-trimethyl-xanthine]
Caffeine a purine alkaloid is a secondary metabolite of the coffee plant.Caffeine is the most widely used psychoactive substance in the preparation of coffee. It makes the people awake for longer time.
Caffeine affects cardiovascular and nervous system.It also increases the metabolism in humans.
Carbohydrates
Carbohydrates are the major constituents of coffee beans and serve various functions like binding of aroma, stabilization of foam, formation of sedimentation, and increased viscosity of the extract.
Chlorogenic acids
Chlorogenic acids (CGA) are cinnamic acid derivatives with biological effects mostly related to their antioxidant and anti-in?ammatory activities.
Benefits of chlorogenic acids
Reduction of the relative risk of
- Cardiovascular disease
- Diabetes type 2
- Alzheimer’s disease and
- Antibacterial activities
Trigonelline
Trigonelline is an alkaloid found in coffee.It will help to prevent dental caries by preventing the bacteria Streptococcus mutans from adhering to teeth.
