Cinnamaldehyde exists in the volatile oil of cinnamon, cinnamon, allspice and other plants, and is widely used in food, cosmetics, flavors, pharmaceuticals and other fields. In food processing, cinnamaldehyde can be used as a flavoring agent to enhance the aroma and taste of food, such as desserts, seasonings, cookies and so on. In cosmetics, it can be used as a spice to enhance the fragrance and odor of cosmetics. In pharmaceuticals, cinnamaldehyde has anti-inflammatory, analgesic, and antibacterial properties and is used in the production of a variety of drugs and health products.
However, since cinnamaldehyde is strongly toxic and irritating, safety should be observed during use to avoid overdose or exposure to cinnamaldehyde.
