  • What are lactones used for?

    Lactones contribute significantly to the flavor of fruit, and of unfermented and fermented dairy products, and are therefore used as flavors and fragrances.

  • What is the content of lactone?

    Lactones are defined by IUPAC as “cyclic esters of hydroxy carboxylic acids, containing a 1-oxacycloalkan-2-one structure, or analogs having unsaturation or heteroatoms replacing one or more carbon atoms of the ring.”

  • What does lactone smell like?

    Lactones smell fruity and milky depending on the length of the chain.
    Lactones are characterized by the presence of a carbon-oxygen double bond in the ring and a ketone group on the side chain.
    In perfumery, lactones have a very specific smell: they're used for their fruity and milky notes.

  • What does lactone smell like?

    Lactones are also esters, but in lactones the ester forms a ring structure.
    Thus, the acid and alcohol groups are part of the same molecule.
    When a lactone hydrolyzes, only one molecule forms, which contains both functional groups, as shown in Figure 3.
