Reader Y1 - 1983/01/01 UR - http://www.ajevonline.org/content/34/2/57.abstract N2 - A method has been developed for the determination of 5-hydroxymethylfurfural in port using reverse-phase high performance liquid chromatography and spectrophotometric detection. The compound is derived from fructose, and its presence in significant amounts can be indicative of blending with reduced musts or caramel, or of madeirization. ER -
