Abstract

Lipid oxidation is among vital deteriorative reactions associated with quality loss of foods, and some oxidation products have toxicity when consumed. Maillard Reaction Products (MRPS) obtained from salmon frame protein hydrolysate (PH) were determined for antioxidant activities. MRPS exhibited superior antioxidant efficacy in both β-carotene linoleate and lecithin liposome systems to PH (p<0.05). MRPS also showed preventive effect toward oxidation in comminuted pork system (p<0.05). The antioxidant potential of MRPS was dose-dependent in all systems tested. Based on cytotoxicity toward Caco-2 cells, MRPS up to 10 mg/mL had no toxicity toward cells when the exposure time was up to 48 h (p>0.05). In addition, the less absorption of MRPS across the Caco-2 cell monolayer was observed as evidenced by the decreased absorbance at 420 nm in the basolateral side (p<0.05). However, small free peptides in MRPS could pass through monolayer effectively. Furthermore, following translocation across the Caco-2 cell monolayer, MRPS exhibited marginally reduced DPPH and ABTS radical scavenging activities, ferric reducing antioxidant capacity, and metal chelating activity. Overall, MRPS were therefore a promising safe antioxidant in various food systems, thus improving oxidative stability of treated foods.
