Abstract
The present invention provides a gasified ice product characterized by a granular, crystalline, porous structure, a brittle texture, good stability in its frozen state, and the ability to rapidly and quietly release its gas content to aqueous solution upon melting therein. The process calls for contacting an aqueous liquid with finely-dispersed bubbles of a conditionally-stable-hydrate-forming gas, such as carbon dioxide, under conditions of temperature and pressure and for a time effective to form a suspension of gas hydrate crystals in the liquid, and then freezing the suspension. The finely-dispersed bubbles of gas are preferably admitted through a porous metal sparger positioned at the bottom of a pressurized reaction vessel. The resulting product preferably has a bulk density of less than 0.60 grams per cubic centimeter and contains from about 30 to about 70 milliliters of gas per gram of product. According to one preferred form of the invention, the product is granulated.
