Green Coffee Bean Extract
Introduction
Green Coffee Bean Extract is obtained from the raw, unroasted seeds of the coffee plant (Coffea arabica or Coffea canephora). Unlike roasted coffee beans, which are primarily used for beverages, green coffee beans retain high levels of chlorogenic acids, natural polyphenolic compounds with strong antioxidant and metabolic benefits.
Chlorogenic acids are recognized for their ability to support weight management, regulate blood sugar levels, and promote cardiovascular health. Research suggests that they help reduce glucose absorption in the digestive tract, improve fat metabolism, and support healthy blood pressure. In addition, their antioxidant activity contributes to protection against oxidative stress.
Commercial production involves careful cleaning, drying, and extraction of unroasted coffee beans, typically using water-ethanol extraction, followed by concentration and spray-drying. The resulting extract is a fine brown to greenish-brown powder, soluble in water and ethanol, and widely used in nutraceuticals, functional foods, and weight management supplements.
