Abstract:

Live transportation of Yesso scallop was simulated by a laboratory simulation platform, and gas chromatographymass
spectrometry (GC-MS) was used to quantitatively analyze volatile components of Yesso scallop during live
transportation. Principal component analysis and discriminant analysis were applied to identify changes in odor
characteristics of Yesso scallop during live transportation. The results showed that 57 volatile compounds were detected
throughout the transportation process, including sulfur compounds, alkanes, nitrogen compounds, heterocyclic compounds,
aromatic, alcohols nitrogen compounds and aldehydes. Sulfur compounds, nitrogen compounds and aldehydes could be
used as reference factors to evaluate the physiological status of Yesso scallop during live transportation. The whole live
transportation was divided into four stages including A (0 day), B (1st–3rd day), C (4th–6th day) and D (7th day). The four
volatile compounds hexane, chloroform, cyclohexene and decanal were identified as the most important factors to estimate
the transportation chain of scallops.
