Abstract
The invention relates to a method of making ice products having a biting texture from an aqueous solution of non-ionic species in a container having a low thermal conductivity and a surface to volume ratio of at least 3.3.
Claims20
A method of making an ice product having a biting texture, comprising:
- supplying a non-ionic aqueous solution containing at least 10% by weight of solute;
- placing said aqueous solution in a container having a thermal conductivity less than 1, the interior of said container being less than about 5 cm in at least one dimension, and the ratio of volume to surface area of said container being at least 3.3;
- subjecting the exterior of said container housing said aqueous solution to temperatures between 28.degree. F. and -40.degree. F. until said aqueous solution freezes, thereby forming an ice product with a biting texture.
A method of making textured ice products, comprising:
- supplying a non-ionic aqueous solution containing at least 10% by weight of solute;
- placing said aqueous solution in a flexible container having a thermal conductivity of less than 1, filling not more than about 80% of the total volume of the interior of said container with said aqueous solution;
- sealing said container;
- then
- placing said container in a horizontal position and subjecting said container to temperatures between 28.degree. F. and -40.degree. F. until said aqueous solution freezes thereby forming an ice product having a biting texture.
