Polyphenolic colorants in sugar manufacture



Polyphenolic colorants in sugar manufacture



Sakharnaya Svekla: Proizvodstvo i Pererabotka ( 5): 59-60



From white sugar was isolated a group of colorants with the properties of polyphenols, strongly adsorbed onto anion-exchange resin and magnesium silicate; polyphenols have several times been isolated from molasses samples. Since any melanins present in diffusion juice should be totally removed at carbonatation, the observed polyphenols were presumed to be generated from sugars during processing, via thermal degradation and/or reaction with alkalis or amino acids.
