Quick Answer
It's generally safe to ferment foods in non-food-grade containers, but it increases the risk of contamination and affects the quality of the fermented product. The type of container, material, and cleaning method used can impact safety and outcome. A well-maintained non-food-grade container can be a viable option.
Choosing the Right Container
When selecting a non-food-grade container for fermentation, consider the material and its potential for contamination. Glass jars with wide mouths are ideal, as they allow for easy cleaning and monitoring of the fermentation process. A 1-quart Mason jar made of borosilicate glass is a good option. Metal containers, such as stainless steel or aluminum, can also be used, but they must be thoroughly cleaned and sanitized to prevent contamination.
Sanitizing and Cleaning the Container
To ensure the container is safe for fermentation, it must be thoroughly cleaned and sanitized. Use a mixture of 1 tablespoon of unscented bleach and 1 quart of water to sanitize the container. Soak the container in the solution for 10-15 minutes, then scrub it with a soft brush to remove any residue. Rinse the container thoroughly with clean water before use.
Monitoring and Maintenance
Regular monitoring of the fermentation process is crucial to ensure the container is not a source of contamination. Check the container daily for signs of mold, yeast, or bacterial growth. If you notice any unusual odors or colors, discard the fermented product and clean the container thoroughly before reusing it. By following proper sanitation and maintenance procedures, you can safely use non-food-grade containers for fermentation.
