Prevention of nanoparticle aggregation during freeze-drying.

Nanoparticle formulations have been widely used in the drug delivery field. The majority of published articles dealing with nanoparticle formulations have focused on the use of freshly prepared nanoparticles, but not many deal with scale-up production of nanoparticles and their long-term preservation by freeze-drying. To date, little information is available on an effective freeze-drying proces...

The Effect of Drying Kinetic on Shrinkage of Potato Slices

Objective: Potato is the fourth important food crop after wheat, rice and maize. Shrinkage  of  food  materials  has  a negative  consequence  on  the  quality  of  the dehydrated product. The main objective pursued in this paper is to investigate the shrinkage amount of potato slices during drying process using vacuum-infrared method. Methods: In this work, the effect of the infrared radiation...

Freeze-drying above room temperature.

This study investigates the use of solid, organic compounds to lyophilize drugs without conventional freeze-drying equipment. The aim of the investigation is to find a pharmaceutically acceptable solvent or solvent combination that is appropriate for freeze-drying on the basis of its ability to (1) solubilize hydrophobic drugs, (2) provide a stable environment for water-sensitive compounds, (3)...
