You can tell what kind of oil was heated by the chemicals it makes — hexanal means it had linoleic acid, while octanal and nonanal mean it had oleic acid.
Scientific Claim
Hexanal is strongly associated with linoleic acid, while octanal, nonanal, and 2-decenal are primarily linked to oleic acid, enabling prediction of LOP profiles based on oil fatty acid composition.
Original Statement
“hexanal was a typical volatile oxidation product of LA... octanal, nonanal, and undecanal was high in OA-rich oils... pentanal, hexanal, 2-octenal, 2-decenal and 2,4-decadienal have a close correlation with LA; heptanal, octanal, nonanal, and 2-decenal have a close correlation with OA.”

Assessment Explanation
Correlation analysis and heat maps support associative claims. 'Is associated with' accurately reflects the statistical relationships without implying causation.
More Accurate Statement
“Hexanal formation during thermal processing is associated with linoleic acid, while octanal, nonanal, and 2-decenal are primarily associated with oleic acid, enabling prediction of lipid oxidation product profiles based on oil fatty acid composition.”

Impact of Heating Temperature and Fatty Acid Type on the Formation of Lipid Oxidation Products During Thermal Processing
The study shows that hexanal comes from oils with lots of linoleic acid, which matches part of the claim, but it doesn’t show that octanal, nonanal, and 2-decenal come mainly from oleic acid, so the full claim isn’t proven.
