What is Cinnamic Acid?

Cinnamic Acid is a fatty acid usually produced from hydrogenated cinnamic acid or other fatty acids. Its chemical structure contains one or more carbon-carbon double bonds and a carboxyl group. Compared with cis-cinnamic acid, trans-cinnamic acid has a different double bond configuration, and the carbon chain is linearly arranged.

Trans-cinnamic acid is often used as an additive in food and industrial production to increase the taste and extend the shelf life of food.

In terms of chemical raw materials, trans-cinnamic acid is mainly used in the synthesis of food additives, industrial greases, lubricants and other chemicals. It has properties such as high stability, strong high temperature resistance, and good oxidation resistance, and is suitable for the needs of various industrial processing processes.
