| 5-Hydroxyoctanoic acid lactone Usage And Synthesis |
| Description | May be synthesized from 5-hydroxyoctanoic acid by reduction
with NaBH4 in water; by microbiological reduction of the corresponding
keto acid; from 5-hydroxyoctanoic methyl amide by
alkaline saponification, using Ba(OH)2. | | Chemical Properties | Δ-Octalactone has a sweet, fatty, coconut, tropical, dairy odor. | | Occurrence | Reported found as a volatile flavor component in coconut oil, butterfat, milk fat, the essence of the Blenheim
variety of apricot, and pineapple, yellow passion fruit, cranberry, currant buds, papaya, peach, raspberry, strawberry, bilberry, plum,
