Crystal growth of ice

Product behavior for a sterile product in manufacturing is also influenced by the conditions imparted due to requirements for aseptic processing. Materials prepared under laboratory conditions in a development environment are typically processed differently than in a manufacturing environment. For example, the level of cleanliness and bioburden are different. Product attributes, such as the nucleation and crystal growth of ice, would occur at different temperatures and rates. This has an influence on product behavior during processing and finished product attributes, as discussed earlier.

Independent of the growth of ice crystals (Section 1.1.2), which can be observed down to approx. -100 °C, and a possible recrystallization (Section 1.1.3), this chapter describes only such developments or changes of structures that can be influenced by additives. The addition of CPAs to albumins, cells or bacteria influences the nucleation of ice - or at least its growth - in such a way that their natural structures are retained as much as possible. On the other hand, additives are introduced to crystallize dissolve substances. If this method does not help, e. g. with antibiotics, the solution concentrates increasingly until a highly viscous, amorphous substance is included between ice crystals. This condition has disadvantages ...

In addition, the relation of this observed widening to the heat balance conditions needs to be further explored.
