RESS/ GAS Applications
Pharmaceutical Application:
- Aerosol drugs require uniform particles and small size
- Must produce sterile powder
- CO2 replaces aseptic conditions + use of EtO sterilizer
Microencapuslation of Flavor and Fragrance: (volatile, themally labile, sensitive to oxidation, expensive)
- Release of flavors during microwaving
- Protection of aspartame during cooking
- Oxidation protection for oils and essences
- Protection during freeze/thaw cycles
