Low Molecular Weight Melanoidins in Coffee Brew

open access: yesJournal of Agricultural and Food Chemistry, 2008
Analysis of low molecular weight (LMw) coffee brew melanoidins is challenging due to the presence of many non-melanoidin components that complicate analysis.

Hyperbranched polyethyleneimine-functionalised chitosan aerogel for highly efficient removal of melanoidins from wastewater.

Journal of Hazardous Materials, 2023
Melanoidins are hazardous dark-coloured substances contained in molasses-based distillery wastewater. Adsorption is an effective approach to eliminate melanoidins from wastewater.

Characterization of Melanoidins in Thermal Hydrolysis Sludge and Effects on Dewatering Performance

Environmental Research, 2023
Thermal hydrolysis pretreatment (THP) of sludge can form the refractory brown melanoidins due to the occurrence of the Maillard reaction, which adversely involves the subsequent sludge anaerobic digestion (AD) process.

Characterization of melanoidins by IR spectroscopy—I. Galactose-glycine melanoidins

Organic Geochemistry, 1986
Abstract A comparative IR spectral study was conducted with synthetic melanoidins which were prepared from various ratios of sugars and amino acids and a pseudomelanoidin which was prepared from sugar only. A significant resemblance was observed between the pseudomelanoidin and the melanoidin prepared from a high (9:1) sugar ratio (type 1). Another

Melanoidins in Coffee

2015
Abstract Coffee roasting influences the taste of the coffee brew by physically and chemically changing the coffee seed. Different compounds found in green coffee beans, such as proteins, polysaccharides, and phenolic compounds, are degraded/transformed to some extent, giving rise to a decrease of the amount of carbohydrates and chlorogenic acids and ...
