Study Cards on co2, removal, sorbitol

How can water be removed from a food product?
  • Slow removal --> leaves original structure intact
  • Fast removal --> formation of highly porous materials
What happens when small molecules, such as glucose, glycerol and sorbitol are added?
They soften materials content a high concentration of polysaccharides or proteins. The use of those molecules leads to soft products, which have a lower water activity.
Why is CO2 used as plasticiser?
CO2 can evaporate at low temperature. The low temperature used during those processes prevents damage of heating sensitive components.
  • Extrusion at low temperature --> slow removal of water --> product with low porosity
  • Fast removal of water --> porous products
  • Higher grades + faster learning
  • Don't study anything twice
  • 100% sure, 100% understanding
