Blueberry sauce can be stored in a frozen state for a long time, usually at least 6 months to 1 year, depending on the quality of the sauce and the freezing conditions.

In order to ensure the quality and flavor of blueberry jam during freezing, it is suggested to store it in a sealed plastic bag or glass jar to avoid the influence of air and moisture on frozen food. After freezing, it can be thawed in the refrigerator, or frozen blueberry sauce can be used directly, which is convenient for long-term storage and eating.

It should be noted that if there is corruption, deterioration, odor or abnormal color during freezing and thawing, blueberry sauce should be thrown away immediately to avoid health problems after eating.
