- Microfluidics is proposed to optimize formulation of fish oil loaded microcapsules.
- Laccase reinforces whey protein microgels and beet pectin in microcapsule shell.
- Calcium chloride weakens electrostatic interactions in the microcapsule shell.
A new technique is presented to optimize the formulation of microcapsules loaded with labile compounds. Fish oil was loaded into the microcapsule core and protected with a shell composed of whey protein microgel/beet pectin complexes. The microcapsules were formed using two different methods: microfluidics and homogenization. The microcapsules were further classified into three sub-groups. The first group was the microcapsules cross-linked with laccase (MCL), the second group was the microcapsules cross-linked with divalent cationic CaCl2 salt (MCS), and the third group consisted of control microcapsules (CM), with no cross-linking. The microfluidics method enabled tracking of the effect of the shell cross-linking ability of laccase, or CaCl2, on microcapsules. It was demonstrated that MCL obtained by microfluidics are more physicochemically stable than those produced via a homogenizer. The effect of cross-linking agents on the microcapsules were more significant when the microcapsules were produced by microfluidics.
