ABSTRACT:
A method of determining whether a brine composition for freezing an item is in a desired balance. The method includes: adding an effective amount of dye into the brine composition, cooling the dye composition to a pre-determined temperature, and comparing the color of the brine composition to a pre-established correlation of color and brine composition at the pre-determined temperature, thereby determining whether the brine composition is in the desired balance.
