Esters are organic compounds derived from the reaction of carboxylic acids and alcohols. They have a carbonyl functional group and ether linkage in their structure. Esters are commonly found in fruits and flowers and provide characteristic aromas and flavors to foods and beverages. They are synthesized through an esterification reaction and can be simple esters, polyesters, or phosphoesters. Esters have widespread industrial uses in pharmaceuticals, cosmetics, and plastics and some have eco-friendly applications due to their biodegradability. The global market for esters was valued at $15.86 billion in 2022 and is predicted to reach $27.25 billion by 2032.
