Melanoidins Extinction Coefficient in the Glucose/Glycine Maillard Reaction

open access: yesFood Chemistry, 2003
Melanoidins (brown, nitrogenous polymers and co-polymers) are the final products of the Maillard reaction. The glucose/glycine melanoidins extinction coefficient was determined using C-14-labelled glucose at three different reaction conditions.

ON MELANOIDIN FORMATION WITH FURFURAL PARTICIPATION: SYNTHESIS OF MELANOIDINS FROM FURFURAL AND GLYCINE

Journal of Food Processing and Preservation, 1983
A method for synthesis of model melanoidins at high yields from furfural and glycine is proposed. It was found that for themelanoidinthe elemental composition, and the IR, UV and mass spectra did not change considerably during the course of the reaction.

Elucidating the production and inhibition of melanoidins products on anaerobic digestion after thermal-alkaline pretreatment.

Journal of Hazardous Materials, 2022
The refractory organics released from waste activated sludge (WAS) are unwanted produced in thermal-alkaline pretreatment, which are not well documented. In this study, we refer to them as melanoidins products (MPs) with characteristics of high molecular
