1. Introduction

Green coffee extract (unroasted Coffea arabica/robusta beans) is rich in chlorogenic acid (CGA) and caffeine. It possesses antioxidant, lipid-lowering, and hepatoprotective effects.

Green coffee beans contain up to 10% chlorogenic acid and 1–2% caffeine. Unlike roasted beans, they retain water-soluble polyphenols. The extract is used in dietary supplements for weight management and liver protection.

2. Structure and Production

Chlorogenic acid (CGA): C₁₆H₁₈O₉ – composed of caffeic acid and quinic acid linked by an ester bond.

Production: Maceration or boiling of bean powder in water or water-alcohol solution, filtration, concentration, and spray drying.

3. Properties

5. Conclusion

Green coffee extract is a source of chlorogenic acid with proven effects on weight management and hepatocyte protection. The recommended dose of CGA is 200–400 mg per day.
