Description
Summary:This study aims to prepare and optimize basil seed mucilage and sodium caseinate as a biocomposite wall to co-encapsulate Lactobacillus acidophilus LA5 and selenium. The efficacy of this biocomposite wall in improving the viability of L. acidophilus LA5 under in vitro acidic conditions was investigated. The mixture design method was applied to find optimal ratio of basil seed mucilage/sodium caseinate as components of the capsule wall. The maximum encapsulation efficiency of the selenium and L. acidophilus LA5 and the minimum zeta potential led to the selection of the optimal ratio of basil seed mucilage/sodium caseinate (basil seed mucilage 58.27% and sodium caseinate 41.73%). Possible cross-linking of basil seed mucilage and sodium caseinate, thermal properties, crystal structure, and morphology of the capsule were investigated using FTIR, DSC, XRD, and SEM tests, respectively. The composite wall of basil seed mucilage/sodium caseinate significantly enhanced the viability of encapsulated L. acidophilus LA5 in comparison to the control sample (free L. acidophilus LA5) (p
