What is Best Method To Preserve Hard Cheese Long-Term?

Wax Coating for Long-Term Preservation

Wax coating is an excellent method for long-term preservation of hard cheese, especially for aged varieties. This technique involves applying a thin layer of wax to the cheese’s surface to prevent moisture from entering the cheese. The ideal wax coating thickness is around 1/16 inch (1.5 mm) to ensure complete coverage without compromising the cheese’s texture. Natural waxes like beeswax or paraffin wax are preferred due to their non-reactive properties. Additionally, wax coating prevents the cheese from drying out, allowing it to maintain its natural moisture content.

Proper Storage for Long-Term Preservation

After wax coating, it’s essential to store the cheese in a cool, dry place with minimal temperature fluctuations. The ideal storage temperature is between 35°F (2°C) and 45°F (7°C). Avoid storing cheese near strong-smelling foods or chemicals, as these can contaminate the cheese. For optimal results, store the cheese in a humidity-controlled environment with a relative humidity of 50-60%.

Additional Preservation Methods

For an extra layer of protection, consider combining wax coating with vacuum sealing or nitrogen flushing. These methods remove oxygen from the cheese’s environment, preventing the growth of mold and bacteria. Vacuum sealing can be achieved using a food saver or a vacuum sealer machine. Nitrogen flushing, on the other hand, involves displacing oxygen with nitrogen gas using a food-grade nitrogen flush system. This method is particularly useful for cheese with high water content or those prone to oxidation.
