Isolation of nonvolatile precursors of .beta.-damascenone from grapes using charm analysis.
Acs Symp. Ser. :
A bioassay for the precursor compound to B-damascenone, trans-2,6,6-trimethyl-cyclohexa-1,3-dienyl-1-but-2-ene-1-one, found in grape skins was developed based on the generation of free B-damascenone and the sensory technique charm. Thin layer, column, and high pressure liquid chromatography were used to separate the precursor from 80 kg of grapes, Vitis labruscana, Bailey cv. Concord. There was a 22,000 fold enrichment in the precursor in 3.7 g of isolate.
