From chemistry to application: cinnamon essential oil as a functional ingredient in food and active packaging systems
摘要
Cinnamon essential oil (CEO) is gaining attention as a natural food preservative due to growing consumer demand for safe, high-quality, and clean-label products. Rich in bioactive compounds such as cinnamaldehyde and eugenol, CEO exhibits strong antimicrobial, antifungal, antioxidant, and anti-inflammatory properties. These characteristics make it highly effective in inhibiting spoilage organisms, pathogens, and oxidative deterioration, thereby extending the shelf life of perishable foods. Beyond its preservative role, CEO has demonstrated additional biological activities, including anti-hyperglycemic, anti-carcinogenic, nephroprotective, insecticidal, and nematicidal effects, further supporting its functional and therapeutic value. Traditional methods like steam distillation are commonly used for extraction, though advanced techniques are being developed to improve yield and preserve bioactivity. In the food industry, CEO is applied across diverse categories such as fresh produce, beverages, bakery, dairy, and meat products helping maintain safety, quality, and sensory attributes. Recent innovations also integrate CEO into active packaging, creating antimicrobial films and coatings that enhance food preservation in a sustainable manner. With its natural efficacy and versatility, CEO provides a promising, eco-friendly alternative to synthetic preservatives, aligning with the modern drive towards healthier food systems and environmentally responsible technologies.
