Preparation of quercetin microcapsules with bovine serum albumin-arabinoxylan cold-set gels as wall material and its application in beef preservation.

ABSTRACT: The aim of this study was to develop microencapsulated freshness preservatives loaded with quercetin based on bovine serum albumin (BSA)-arabinoxylan (AX) cold-set gels, which were induced by glucono-δ-lactone (GDL), NaCl, and laccase, and to evaluate their freshness preservation effect on beef. Results showed that the GDL-laccase-NaCl condition achieved the highest quercetin encapsulation rate (88.98 %) and free radical scavenging rate (94.08 %), with a minimum inhibitory concentration of 3.125 mg/mL against Brochothrix thermosphacta. FT-IR and XRD structural characterization also demonstrated that the quercetin and the wall material connected by hydrophobic interactions and hydrogen bonding. When applied to beef preservation at 1.5 % of meat weight, the microcapsules effectively d
