And Function

Under certain conditions, chitosans can react with different types of reducing sugars to form various final Maillard reaction products (MRPs). In this study, the optimal reaction conditions were selected, and three different final MRPs (xylose-MRPs, fructose-MRPs, glucose-MRPs) were analyzed. The structure of the three MRPs was analyzed using fluorescence, ultraviolet, and infrared spectroscopic methods, and then the antioxidant activities of the three MRPs were determined. The results showed that the three MRPs have similar structure and function, and the antioxidant activities between them have certain regularity. Antioxidant activities were ranked as follows: xylose-MRPs>fructose-MRPs>glucose-MRPs, and this order was inversely proportional to their reaction time, that is, shorter the reaction time, higher the antioxidant activity, while longer the reaction time, lower the antioxidant activity.

Initial Ph

The characterization and antioxidant activity on Maillard reaction products (MRPs) derived from xylose and bovine casein hydrolysate (BCH) was investigated at 100 °C and initial pH 8.0 as a function of reaction time. The pH values and free amino groups contents of xylose–BCH MRPs remarkably decreased with the reaction time up to 8 h, whereas their browning intensities significantly increased (p < 0.05). After 4 h of heat treatment, the fluorescence properties of xylose–BCH MRPs reached the maximum. There was a production of higher and smaller molecular substances in xylose–BCH MRPs with an increased reaction time, as analyzed by size exclusion chromatography. The 2,2-diphenyl-1-picryl-hydrazyl (DPPH) free radical scavenging capacity and ferrous reducing activity of xylose-BCH MRPs gradually increased with the reaction time extended from 0 to 8 h.

Maillard Reactions

Maillard reactions between chitosan and glucosamine were induced by Co-60 gamma irradiation method and the antibacterial and antioxidant activities of resulting products were investigated. Briefly, a mixture of chitosan (1%) - glucosamine (0.5%) was irradiated with a dose range of 0-100 kGy. The Maillard reaction products of chitosan and glucosamine (CTS-GA MRPs) were analyzed by UV spectrophotometry, and residual glucosamine was determined by high performance liquid chromatography (HPLC). Antibacterial and antioxidant activities of the CTS-GA MRPs were investigated with radiation dose and pH by using directly contacted and ATBS•+ free radical scavenging methods. The results indicated that the CTS-GA MRPs formed at 25 kGy exhibited high antibacterial activity at both pH 5 and 7. On the other hand, antioxidant activity of CTS-GA MRPs increased with the increase of dose. The results also revealed that CTS-GA MRPs with high antimicrobial and antioxidant activities are potential candidates as preservative agents in food processing and cosmetics.

Chitosan-galactose Maillard reaction (CG) were prepared by heating at 100 °C for 3 hrs in a model system containing chitosan (CH) and 1%, 1.5% and 2% (w/v) of galactose. The results showed that the absorbance at 294 and 420 nm, the fluorescence intensity and the color differences of CG Maillard reaction products (MRPs) increased significantly with the increase of galactose concentration, which indicated the development of MRPs. In addition, FT-IR analysis showed that the degree of deacetylation of CG-MRPs was reduced with the increasing galactose ratio by the schiff base (–C=N) formation, indicating that the galactose has been attached to the amino group of chitosan. Likewise, the antioxidant activities (DPPH, chelating ability and reducing power) of CG-MRPs were investigated. Notably, the effect of galactose concentration in CG-MRPs was found to enhance the antioxidant activity, indicating that CG-2% exhibited the highest antioxidant activity in the range of 0.25–2.0 mg/mL. Furthermore, the apple juice supplemented with CG-MRPs could significantly improve the antioxidant activities, and CG-2% in apple juice showed the better antioxidant capacity at the concentration of 1.0 mg/mL. Thus, we conclude that CG-MRPs addition may greatly improve the antioxidant quality of apple juice.

Predominant Component

Maillard reaction products (MRPs) could offer flavor and aroma for food, and also render functional characteristics. In this work, three squid skin Maillard reaction products with glucose (GSS), fructose (FSS) and lactose (LSS) were prepared, whose volatile compounds were analyzed by gas chromatography-mass spectrometer. And the antibacterial activities of three Maillard reaction products against Escherichia coli, methicillin-resistant Staphylococcus aureus and Vibrio harveyi were investigated. The results showed that the volatile compounds of squid skin MRPs mainly contained alcohol, acid, phenol, ester, aldehyde, alkane, alkene, amide and ester, among which alcohol was the predominant component in the GSS and LSS, accounting for 53.87±6.02 % and 83.67±3.64%, respectively, however, acid was predominant component in the FSS, accounting for 54.19±3.38 %. Surprisingly, 2, 6-di-tert-butyl-4-methylphenol (BHT), as a synthetic antioxidant, was firstly identified in these three MRPs, which directly indicated squid skin MRPs have antioxidant activities. It is demonstrated that the antibacterial abilities of LSS and GSS were superior to that of FSS, and Escherichia coli was the most sensitive to the three MRPs among the three tested bacteria. This study demonstrates squid skin MRPs possess antioxidant and antibacterial abilities, which shows promising and far-ranging prospect in the fields of food additives.
