Melanoidins in the Maillard reaction
1998Abstract This paper is a review of the studies on melanoidins, the end heavy products of the Maillard reaction. It deals with the description of melanoidins in foods and model systems as well as their physical and chemical methods of analysis, their chemical properties and their biological and antioxidative activities in vivo and in nature.

New biological properties of coffee melanoidins
Food & Function, 2013Water-soluble melanoidins isolated from roasted coffee induced ex vivo changes in the bioelectric and contractile activity of rat circular gastric smooth muscle tissues. They provoked a depolarization of smooth muscle cellular membranes and an increase in Ca²⁺-influx as evidenced by the increase in the frequency and amplitude of Ca²⁺-generated spike ...

Adsorption of melanoidins by chitin nanofibers
Chemical Engineering Journal, 2011Abstract Melanoidins, the complex bio-polymer of amino-carbonyl compounds are widely distributed in food, drinks but if it was discharged into a water resource system that affect as environmental pollutants. Adsorption is a potential method to remove the color from the food or environment.

Nature of Phenolic Compounds in Coffee Melanoidins
Journal of Agricultural and Food Chemistry, 2014Phenolic compounds are incorporated into coffee melanoidins during roasting mainly in condensed form (42-62 mmol/100 g) and also in ester-linked form (1.1-1.6 mmol/100 g), with incorporation levels depending on the green coffee chlorogenic acid content.

Melanoidins are high molecular weight brown compounds containing nitrogen, defined as end products of Maillard reaction. Coffee brews, prepared from roasted and ground coffee beans, are one of the main sources of melanoidins in the human diet. Polysaccharides, proteins, chlorogenic acids, and sucrose are involved in coffee melanoidins formation ...

Thermal Degradation Studies of Food Melanoidins
Journal of Agricultural and Food Chemistry, 2005Food melanoidins were isolated from bread crust, coffee, and tomato sauce and their composition was investigated by thermal degradation. Among the generated volatiles, important food flavor compounds were detected: in particular furans, carbonyl compounds, 1,3-dioxolanes, pyrroles, pyrazines, pyridines, thiophenes, and phenols.

The role of peptides and proteins in melanoidin formation
Journal of Mass Spectrometry, 2009AbstractHigh‐molecular‐weight (HMW) coloured compounds called melanoidins are widely distributed, particularly in foods. It has been proposed that they originate through the Maillard reaction, a non‐enzymatic browning reaction, due to the interaction between protein or peptide amino groups and carbohydrates. The melanoidin structure is not definitively

Abstract The infrared spectra of melanoidins which were prepared from galactose and neutral and basic amino acids (at various ratios) support in general the conclusion gained in Part I of this series. A striking resemblance in the IR spectra was obtained in melanoidins which were prepared from a high ratio of sugar to amino acids (Type 1).

Investigations on the structural units of melanoidins
Organic Geochemistry, 1984Abstract A series of sugar-amino acid derived melanoidins were synthesized and their chemical and physical properties were evaluated using spectral, chemical and thermal analyses. It is suggested that the melanoidin “back-bone” is probably a sugar-moiety polymer in which various nitrogen containing groups are grafted.

Biological Effects of Coffee Melanoidins
2015Coffee melanoidins are brownish high-molecular-weight compounds produced during coffee roasting. There are a plethora of fractions with different chemical composition–structure and probably different biological effects behind the term “coffee melanoidins.” Such biological activities include antioxidant, antimicrobial, antihypertensive, prebiotic ...
