Lastly, a change in texture, such as excessive separation or a dry, hard consistency instead of a smooth, spreadable form, indicates that it may no longer be fresh.
While black garlic paste is generally safe, improper storage can lead to spoilage and potential foodborne illness. Always store in the refrigerator and use clean utensils to avoid contamination.
To prevent freezer burn, wrap black garlic paste tightly in plastic wrap or use a vacuum sealer before freezing. Label containers with dates to keep track of storage time.
