What is a cryoprotectant?

Cryoprotectant is a chemical compound that limits damage to biological tissues in freezing conditions. Without protection, the cell bursts when they freeze due to water expansion, cause serious injury or death of living organisms and destroy tissue samples or frozen food products. Some animals naturally produce their own cryoprotectants as an adaptation to the cold climate. Synthetic versions are available for biological materials put into storage, from tissues for research to frozen meals. A common approach is to reduce the freezing point and maintain tissue flexible at temperatures that would normally lead to frost. Others are associated with specific molecules to help tissue maintain their structure under intensive low temperature pressures. In organisms such as insects, fish and amphibians, cryoprotectants allow you to live in extreme climate such as ocean bottoms or very cold superfers. Organic, tissue and blood banks often freeze donor material for later use and must be for Bezposness to control the conditions of frost and thawing. Samples taken for biopsy or offspring can also be frozen to maintain. Materials can be frozen in the bathtub of the cryoprotectant or soaked in the compound for protection. For things like blood, a chemical is added to form a fluid solution before the material enters the freezer for storage.

The type of cryoprotectant suitable for use in a given application may vary. For things such as tissues for transplantation, doctors must use non -toxic compounds to prevent patients to experience poor reaction. Materials for studying or diagnostic testing can be treated with multiple hazardous chemicals because they will not be implanted or converted to patients. Medical supply companies produce products of cryoprotectants for different purposes and clearly indicate the recommended use on the designation.

in food production keeps cryoprotectants frozen JIt was fresh and allowing it to keep the texture and color. Companies producing commercially frozen foods use these compounds to treat their products. People freezing food at home can use homemade cryoprotectance solutions to ensure that things like meat and vegetables remain in good condition in the freezer. For example, the meat can be frozen in the marinade, allowing sugars in the marinade to protect the meat from the freezer burns and facilitates the preparation of meat later.
