Thus, smaller ice crystals are formed, causing less damage to cell membranes. [4] Flash freezing techniques are used to freeze biological samples quickly so that large ice crystals cannot form and damage the sample. [5] This rapid freezing is done by submerging the sample in liquid nitrogen or a mixture of dry ice and ethanol. [6]
Dry ice is the solid form of carbon dioxide (CO 2), a molecule consisting of a single carbon atom bonded to two oxygen atoms. Dry ice is colorless, odorless, and non-flammable, and can lower the pH of a solution when dissolved in water, forming carbonic acid (H 2 CO 3). [1]

Low-temperature cooking methods include sous vide cooking, slow cooking using a slow cooker, cooking in a normal oven which has a minimal setting of about 70 °C (158 °F), and using a combi steamer providing exact temperature control.
Brining is typically a process in which meat is soaked in a salt water solution similar to marination before cooking. [2] Meat is soaked anywhere from 30 minutes to several days. The brine may be seasoned with spices and herbs. The amount of time needed to brine depends on the size of the meat: more time is needed for a large turkey compared to ...
