The key factor at freeze-drying of protein and peptide structures, to which food products also relate, is long term stability. Proteins are labile molecules, the structure of which requires strict control of water quantity in the composition — both in the process of sublimation, and after it ends.
The problem of protein instability at freeze-drying can be solved only by means of constant optimization of recipes and strict control on all the process stages, and also usage of auxiliary materials: cryoprotectors, exipients, regulators.
Namely careful selection of recipes and methods for each exact product is what specialists of research labs of RND LIO-Product do.
