Why in the process of oil storage , in presence of oxygen ,hexanal is a maker of storage in the light,but it is the octane that in the absence of oxygen
The volatile compounds hexanol,
hexanal, and 1-penten-3-ol were responsible for the discrimination of cultivars. All maturity stages
ix
were discriminated, with the separation of early stages attributed to oil phenolic compounds, tyrosol
and oleuropein derivatives, whereas the volatile compounds (E)-2-hexenal, hexanol, 1-penten-3-ol,
and (Z)-2-penten-3-ol characterized the separation of all maturity stages and in particular the late
stages. Hexanol and 1-penten-3-ol characterized the separation of both cultivars and maturity stages.
