Introduction
Caffeic acid is an organic acid that occurs naturally in coffee beans and other plants, and it is found in trans and cis isomers. The trans isomer of caffeic acid, also known as the trans form of caffeic acid, has the following properties: Chemical properties: The trans isomer of caffeic acid is a white solid that is relatively stable at room temperature. It is a derivative of polyhydroxyphenylpropionic acid with surface activity and antioxidant properties. Taste and aroma: Caffeic acid trans isomers usually have a sour taste, and excessive organic acid accumulation may have some effect on the mouthfeel. Method: Caffeic acid trans isomers can be extracted by roasting, grinding and other processes of coffee beans. It can also be prepared by chemical synthesis. For individual populations such as pregnant women, infants and other special populations, the intake of caffeic acid trans isomers in the diet should be appropriately controlled.
