Mechanism
Synthesis from 1 study
When fat is burned at high heat, it breaks into tiny chemical pieces that look just like the pieces plastic makes when burned. Machines that detect plastic can't tell the difference, so they think the fat is plastic, even though it's not.
Most probable mechanism
When fat from the body is heated to very high temperatures, it breaks apart into small chemical pieces that look exactly like the pieces made when plastic is heated, causing machines to mistake the fat for plastic.
Lipid molecules in adipose tissue undergo thermal cleavage at pyrolysis temperatures, producing a mixture of saturated and unsaturated hydrocarbons with chain lengths and branching patterns overlapping those of polyethylene.
These hydrocarbon fragments volatilize and enter the gas phase, where they are ionized and detected by mass spectrometry as molecular ions with mass-to-charge ratios identical to those of polyethylene degradation products.
The resulting chromatographic peaks and mass spectral fingerprints lack distinguishing features that can reliably differentiate between biologically derived hydrocarbons and synthetic polyethylene fragments.
