What term describes odoriferous compounds resulting from reactions between acids and alcohol?

The term that describes odoriferous compounds resulting from reactions between acids and alcohol is esters. Esters are organic compounds formed through the reaction of an alcohol and a carboxylic acid, typically during a process called esterification. This reaction not only produces the ester but is often characterized by the formation of fragrant compounds that contribute to the pleasant aromas found in many fruits and beverages.

Esters are widely used in the food and beverage industry because they can impart fruity, floral, and sweet notes, making them essential for flavoring and aroma in various products.

While aldehydes, phenols, and terpenes also play significant roles in the production of flavors and aromas, they originate from different chemical reactions or structures. Aldehydes come from the oxidation of alcohols, phenols are derived from aromatic compounds, and terpenes are built from isoprene units and are typically found in essential oils. Therefore, esters specifically refer to the reaction between acids and alcohols, making them the correct choice for this description.
