Geranial is an organic compound that is categorized as a terpenoid aldehyde. It is also commonly referred to as citral A due to its strong citrus-like aroma and flavor. Geranial is naturally found in various plants and is a key component in the essential oils derived from lemon, lime, orange, and other citrus fruits. It is also present in certain herbs like lemongrass, verbena, and lemon balm.
Chemically, geranial consists of a linear chain of ten carbon atoms, with a double bond between the third and fourth carbons. It contains an aldehyde functional group at one end of the chain, which gives it its characteristic odor. Geranial is a pale yellow liquid with a strong, sweet, and lemony fragrance.
In terms of its uses, geranial is widely employed in the fragrance and flavor industry. It is particularly valued for its fresh, zesty, and floral notes, often found in perfumes, soaps, lotions, and various cosmetic products. Its potent citrus flavor also makes it a popular ingredient in food and beverage items such as candies, desserts, chewing gum, and soft drinks.
Furthermore, geranial possesses antimicrobial properties and is commonly used as a natural preservative in the food and cosmetics industries. It is known for its ability to inhibit the growth of certain bacteria and fungi, thus extending the shelf life of products. Moreover, geranial has been investigated for its potential health benefits, including antioxidant, anti-inflammatory, and anticancer properties, though further research is still needed to fully understand and validate these claims.
