Application and characterization of cryogels in food technology

Cryogels are polymeric materials that consist of monomeric or polymeric precursors in a relatively frozen
state with polymerization or crosslinking. The process to form cryogels is called cryogelization. These
big gel matrices can be produced in various forms. High porosity, high mechanical and chemical stability
make them an appropriate carrier for biomolecular and cell stabilization and as a result, create attractive
gel matrices for the separation and purification of different molecules.
Cryogenic processes are generally used to create polymeric materials, which due to the special properties
of cryogels, they are used in various fields, especially medicine, environmental toxicity and food
technology. In this study, the production of XG, HEC, PVA, chitosan PVA, β-glucan and the use of them
were investigated.
It is clear that further studies are needed to make progress in this area and to use cryogels.
