Eugenol is found in essential oils of various plants. Eugenol is considered as versatile molecule used as an ingredient in various products including pharmaceutical, food industry, fragrance, flavor, cosmetics, etc. Eugenol also exhibits antioxidant, antibacterial, anti-microbial, anti-cancer, and anti-inflammatory activities. Around 80-90% of eugenol is present in clove bud oil, while around 82-88% of eugenol is present in clove leaf oil. Hence, clove is considered as the main source of eugenol. Manufacturers are also practicing new methods for extracting eugenol from clove oil. Solvent extraction, microwave-assisted extraction, and hydro-distillation are some of the highly-preferred extraction processes employed by producers. The food industry is moving towards the application of eugenol in food preservation owing to its antimicrobial properties. The rise in foodborne diseases worldwide is driving the demand for eugenol as a part of an effective preservation strategy.
