Fabrication of novel functional anisotropic micro-particles for foam stabilisation and structuring in food formulations
… micro-rods from the edible polymeric materials shellac, ethyl cellulose and zein. Characterisation of the properties of shellac, ethyl cellulose and zein micro-rods was carried out, together with assessments of their foam stabilisation ability. Stable aqueous foams were produced using shellac, …

Characterization and reduction of leakiness in melamine formaldehyde microcapsules
… nanoparticles outer wall. Finally, calcium shellac matrix containing MF microcapsules and unripened CaCO\(_3\) nanoparticulate microcapsules (complex capsules) were also produced to reduce the leakage. A ~37 fold leakage reduction between calcium shellac matrix containing MF microcapsules …

Novel techniques for microencapsulation of probiotic bacteria
… after the microencapsulation.We fabricated novel shellac-yeast cells composite microcapsules programmed to release the cells upon change of pH in a narrow range. This was achieved by either spray drying or sprays co-precipitating dispersion of yeast cells in aqueous solution of ammonium shellac …

Microneedles for Drug Delivery in Aquaculture
… found that hollow, silk microneedles coated in shellac/ethanol coatings of 33.3% w/w following the two-step method of full dip coating then tip-only dip coating was able fully coat microneedles. Compression testing was done on individual needles in their dry state and after 30 minutes of soaking …

Characterizing Organic Coatings on Renaissance Bronzes with Short-Wave Infrared and Mid-Infrared Spectroscopy
… blend. Additionally, the application of wax and shellac was explored, and unique ER-FTIR and FORS markers were determined for the identification of non-original re-coatings. This protocol was applied in situ to small bronzes from the Royal Ontario Museum: Venus after the Bath, Lion Attacking …
