Study Cards on lipid, starch, emulsifiers

The moisture content of an oil droplet dispersed in water is almost zero. T/F
True
Report
When making a coating material from an oil-in-water emulsion
  • Increasing the lipid volume fraction will linearly increase the permeability to moisture of the coating
  • A very small increase in the lipid volume fraction will dramatically increase the permeability to moisture of the coating
  • The use of emulsifiers will help to improve the physical stability of the emulsion, and thereby the quality of the coating
  • Increasing the lipid volume fraction will enhance the mechanical strength of the coating
The use of emulsifiers will help to improve the physical stability of the emulsion, and thereby the quality of the coating
Report
Which coating material and application procedure would you choose to coat Brussels sprouts, to maintain their content in vitamin C and polyphenols (i.e., antioxidants) during storage?
  • A lipid, that would be sprayed on the Brussels sprouts
  • Corn starch, that would be applied by dip casting followed by drying
  • An emulsion with a high oil volume fraction, that would be applied by spraying, then dried
  • Beeswax, that would be applied in a melt bath (solidification of the waxon the Brussels sprouts directly in the bath)
Corn starch, that would be applied by dip casting followed by drying
