ANALYSIS OF FLUOCRESCENT COLORANTS AND COLOR PRECURSORS IN CANE SUGAR MANUFACTURE USING SPECTROFLUOROMETRY AND MULTIVARIATE DATA ANALYSIS

摘要

Fluorescence of raw sugar is correlated to ICUMSA color, and the three main fluorophores represents a color precursor of storage color and two colorants. Model colorants from the Maillard and sugar degradation reactions contain fluorescence of rather equal appearance that seems to represent the same colorant formation pathways. Process samples from a cane sugar factory showed colorant fluorescence in the earliest process stages, and the same fluorophore pattern is repeated through the process with a slight development of colorant fluorophores.
