- •
Trans-3,4-dideoxyglucosone-3-ene (trans-3,4-DGE), a most reactive glucose degradation product, in heat sterilized dextrose 5% in water (D5W) was identified.
- •
The trans-3,4-DGE was identified by reaction-directed fractionation of D5W, derivatization, and structure elucidation of the derivatives by MS and NMR.
- •
The presence of trans-3,4-DGE in heat sterilized D5W was confirmed with authentic trans-3,4-DGE and NMR analysis of the reactive fraction.
