Abstract:

The spherical multinuclear microcapsules of peppermint oil were prepared by complex coacervation, and the effects of various process parameters on the heat resistance of microcapsules were investigated. When core to wall ratio, wall material concentration and pH value are lower than 2:1, 1% and 4.0 respectively, the microcapsules with stronger heat resistance can be obtained. Moreover, the heat resistance of microcapsules increases following with the amount increase of bridged agent formaldehyde. Also, transglutaminase can be used instead of formaldehyde to produce highly heat-resistant and edible microcapsules.

Key words: microcapsule, complex coacervation, peppermint oil, bridged agent, transglutaminase
