were not also derived from other fatty
acids. The fatty acid C20:2 has been reported to give
2-octen-1-ol, but this fatty acid is only present in small amounts
compared to C20:4 (Raes et al., 2003). Hexanal and 2-octen-1-ol
were, as expected, the highest in high oxygen packaging (Ullrich
& Grosch, 1987).
