3.7. IMP content
The changes in IMP concentration are shown in Fig. 8. ATP-related
compounds the samples stored for 14 days are shown in Fig. 9. During
the storage period between two days and one year, the ohmically
heated samples had significantly higher IMP concentration than the
retort-heated samples (p b 0.01). The x-axis represents the measured
sample, and the y-axis shows the content of ADP, AMP, ATP, and HxR.
ATP changes into ADP, ADP changes into AMP, AMP changes into IMP,
IMP changes into HxR, and HxR changes into Hx. The decreases in
ATP, ADP, and AMP lead to an increase in IMP content. Conversely,
increases in HxR and Hx lead to a decrease in IMP content. IMP
concentration changed to HxR, Hx and so on. IMP concentration in
both the sample types remained nearly constant across storage periods.
This suggests that IMP concentration did not change during storage. IMP
