Recent Advances and Applications of Freeze-Drying Technology
Abstract
Despite the advances which have been made during the past thirty years, freeze-drying continues to be more of an art than a science. Although the value of the material processed annually must be on the order of hundreds of millions of dollars, the process of freeze-drying is still greatly underresearched. Lacking especially is a completely satisfactory unified body of theory which would enable a protocol to be drawn up prior to processing on the basis of a few known properties or parameters of the material to be dried. In spite of these restraints, there exist excellent techniques of instrumentation and process control [1] and powerful statistical methods and mathematical models to predict the shelf-life of freeze-dried material [2,3]. Although these studies enable the processor to work on a firm empirical basis, unfortunately they are still widely ignored or misunderstood.
