Preservation of bioactive materials by freeze dried foam |
abstract |
This invention provides methods, systems and compositions to preserve bioactive materials in a dried foam matrix. Methods provide non-boiling foam generation and penetration of preservative agents at temperatures near the phase transition temperature of the membranes. Bioactive materials can be preserved with high initial viability in a freeze-foam process employing low temperature secondary drying. |
