To improve the utilization of cod skin collagen peptides (CSCP), we heated them with xylose at 80 °C, 100 °C, and 120 °C for up to 150 min to prepare xylose-CSCP Maillard reaction products (MRPs), and then investigated their physicochemical and functional properties. The results showed that Arg, Lys, Phe, and Asp were the major amino acids involved in the Maillard reaction. After being heated at 120 °C for 150 min, the ABTS scavenging activity and reducing power of xylose-CSCP MRPs were 99.59% and 0.887 absorbance units, respectively. Xylose-CSCP MRPs had better emulsifying properties and foaming properties than CSCP. Furthermore, 26 volatile compounds, including 2,5-dimethyl-pyrazine and 2-ethyl-3,5-dimethylpyrazine, were identified from xylose-CSCP MRPs by gas chromatography-ion mobility spectrometry. Newly formed heterocyclic compounds might be responsible for the flavor and antioxidant capacity of xylose-CSCP MRPs. These results suggest the potential for xylose-CSCP MRPs to serve as functional food ingredients.

UI MeSH Term Description Entries
D010455 Peptides Members of the class of compounds composed of AMINO ACIDS joined together by peptide bonds between adjacent amino acids into linear, branched or cyclical structures. OLIGOPEPTIDES are composed of approximately 2-12 amino acids. Polypeptides are composed of approximately 13 or more amino acids. PROTEINS are considered to be larger versions of peptides that can form into complex structures such as ENZYMES and RECEPTORS. Peptide,Polypeptide,Polypeptides

D015416 Maillard Reaction A group of nonenzymatic reactions in which ALDEHYDES; KETONES; or reducing sugars react with the amino groups of AMINO ACIDS; PEPTIDES; PROTEINS; LIPIDS; or NUCLEIC ACIDS.The reaction with reducing sugars (glycation) results in formation of Schiff bases which undergo Amadori rearrangement and other reactions that result in the irreversible formation of ADVANCED GLYCATION END PRODUCTS (AGEs). Food browning, such as occurs when cooking with high heat (grilling, frying, roasting, etc.) is attributed to the Maillard reaction. Non-enzymatic glycation and subsequent formation of AGEs also occurs in vivo and is accelerated under hyperglycemic and inflammatory conditions, and OXIDATIVE STRESS.
