This laboratory study found that zirconium acetate and zirconium acetate hydroxide slow ice crystal growth, show a small thermal hysteresis depending on pH, and inhibit ice recrystallization in a way similar to antifreeze proteins. Frozen food and cell preservation are discussed as possible uses, but no food was tested and no safety data are given.
Key numbers
- This paper reports no numerical findings relevant to zirconium exposure.
Methods (brief)
Microscopy of ice crystal growth, thermal hysteresis and recrystallization in solutions of the two zirconium compounds at different pH values.
Evidence fitness
Off-topic for dietary exposure. The paper uses zirconium acetate compounds as candidate ice-growth inhibitors; it does not support dietary exposure or toxicity claims for zirconium. Mentions of frozen food use are prospective and untested.
Limitations
No zirconium was measured in food, water, soil or human samples, so nothing in the paper describes exposure.
