Analysis of Methionyl Acetate in Canary Melon Using Stable Isotope Dilution Analysis... [Pg.92]

Stable isotope dilution analysis was used to determine the amount of 3-methylthiopropyl acetate (methionyl acetate) in the fruit of a ripe canary melon. A deuterium-labeled standard was prepared from 3-methylthiopropan-l-ol and acetic anhydride-dg using standard organic synthesis practices, and it was distilled... [Pg.92]

Figure 9 Graph showing the decrease in peak area (circles) of methionyl acetate isolated from a Canary melon puree by headspace SPME versus the amount calculated (triangles) using stable isotope dilution analysis. A 100-g sample of the puree was spiked with 100 Xg of deuterated methionyl acetate and 5-g samples were removed from refrigeration at regular intervals for SPME GC/MS analysis. The mean of the calculated amount was 3.99 0.07 xg/g.
