2004 DEC 29 - (NewsRx.com & NewsRx.net) -- The physical and aerodynamic features of spray-dried protein powders have been determined.
In a study from Belgium, "[p]owder aerosols made of albumin, dipalmitoylphosphatidylcholine (DPPC) and a protein stabilizer (lactose, trehalose or mannitol) were prepared by spray-drying and analyzed for aerodynamic behavior, surface composition and physical state."
"The powders exited a Spinhaler inhaler as particle aggregates, the size of which depending on composition, spray-drying parameters and airflow rate," C. Bosquillon and coauthors at the Catholic University of Louvain found. "However, due to low bulk powder tap ...
