Unlocking the Full Potential of Clove (Syzygium aromaticum) Spice: An Overview of Extraction Techniques, Bioactivity, and Future Opportunities in the Food and Beverage Industry

What if the secret to healthier food and drink has been hiding in your spice rack all along? Clove, a humble spice, packs a powerful punch of bioactive compounds that could transform the food and beverage industry.

Clove isn't just for holiday hams. This aromatic spice is a treasure trove of phenolic compounds, especially eugenol, which boasts antioxidant, anti-inflammatory, antimicrobial, antifungal, and wound-healing properties. But getting those benefits out of the clove is no easy feat.

Traditional extraction methods like Soxhlet and maceration have their limits—they're often slow, wasteful, and can degrade the very compounds we want. Enter green extraction techniques: ultrasound-assisted, pressurised liquid, and microwave-assisted methods. These modern approaches promise higher efficiency and better preservation of bioactivity.

The review also explores how clove extract could be used in food and beverages, from natural preservatives to functional ingredients. Yet, challenges remain—scaling up, cost, and regulatory hurdles are just a few.

Ultimately, clove extract shines as a natural source of bioactive compounds with immense potential. The future of food might just be spiced with cloves.

Key Points

• Clove is rich in eugenol, a phenolic compound with multiple health benefits.
• Green extraction methods outperform traditional techniques like Soxhlet and maceration.
