What is CGA In Coffee?

Chlorogenic acid (CGA) is a broad group of esterified chemicals in green and roasted coffee discovered in 1932. CGA breaks down slowly during roasting in medium roasts to generate caffeic and quinic acids, which account for about half of the original CGA.


Chlorogenic acid’s (CGA) molecular structure

Coffee’s Chlorogenic Acid (CGA):

Because quinic acid and caffeic acid are heat sensitive, darker roasts have higher degrees of astringency, bitterness, and body normalcy.

 Ingredients selected for raw coffee (%):


Coffee contains the highest chlorogenic acid content of any plant species, ranging from 6-7 percent in Arabica to up to 10% in Robusta.

Various causes, including changing climatic circumstances, plant stress, and pest infestation, cause CGA production in plants. Robusta contains roughly twice as much CGA as Arabica, despite growing in harsher circumstances.

Because the production of CGA is identical to that of caffeine, when the concentration of CGA rises, the concentration of caffeine increases as well.


Even though the word chlorogenic acid refers to a single chemical, there are more than a dozen isomers with distinct organoleptic properties. In coffee, the 3-CGA isomer predominates, with mono, di, and feruloyl quinic acids present in various amounts.

According to research, the bitter/metallic flavor notes seen in some coffees may be due to the “di-CGA” version of the acid. This is most likely true for Robusta coffees, with higher di-CGA concentrations and a darker flavor profile.

According to the most recent studies, coffee has potent antioxidants, ranging from 200 to 550 mg per cup (6 oz) – far more than green tea. Although coffee and tea are high in antioxidants, coffee has a more significant concentration of simple phenols, while tea has a higher concentration of catechins.

CGA’s effects on the human body

Chlorogenic acid is a fantastic weight loss agent, according to new research published in the Indian Journal of Innovative Research and Development, thanks to three significant purposes listed below:

Aids in the acceleration of the body’s metabolism. We all know that the faster your body’s metabolism, the quicker you’ll lose weight. It’s worth noting that the chlorogenic acid in green coffee aids in increasing the basal metabolic rate (BMR), which reduces the flow of glucose from the liver into the bloodstream, causing the body to begin burning excess fat, resulting in weight loss.

It suppresses the appetite. Overeating is the cause of weight gain, but fresh coffee will be your “savior,” as it functions as a natural appetite suppressant, keeping you from overeating. Not only that, but drinking this type of coffee daily lowers the body’s craving for fat and carbs.

Sugar consumption should be limited. Fresh coffee lowers sugar absorption in the small intestine, making it less likely for the body to store sugar as fat.

Fresh coffee has numerous health benefits in addition to weight loss:

They are preventing chronic disease and assisting in the treatment of diabetes. Green coffee’s chlorogenic acid has been demonstrated to lower the risk of cardiovascular disease while also balancing blood sugar levels. Glucose is well known to be one of the primary causes of diabetes. As a result, controlling blood glucose levels will aid in diabetes management. Experts say that drinking fresh coffee in the right proportions can help to reduce the risk of diabetes.

Against the effects of aging Chlorogenic acid has also been demonstrated to help cure dry, flaky skin and enhance skin health. One of the essential benefits of fresh coffee is that it aids in the moisturizing process of the skin.

Boost your mood. Green coffee’s mild caffeine level aids mental health by enhancing memory, attentiveness, and a positive mindset.
