Do soybean paste need to be refrigerated after opening?

Yes, soybean paste (also known as doenjang) should be refrigerated after opening to maintain its quality and flavor. Soybean paste is a fermented product made from soybeans and contains live microorganisms. Refrigeration helps to slow down the fermentation process and prevent spoilage.

Here are some tips for storing soybean paste:

- Transfer the soybean paste to an airtight container after opening.

- Store the soybean paste in the refrigerator at a temperature of around 40 degrees Fahrenheit (4 degrees Celsius).

- Consume the soybean paste within a few months of opening for the best flavor.

- If you notice any mold or off-odors, discard the soybean paste.

Soybean paste can also be frozen for longer storage. To freeze soybean paste, transfer it to a freezer-safe container and freeze it at a temperature of 0 degrees Fahrenheit (-18 degrees Celsius). Frozen soybean paste can be stored for up to 6 months. Thaw the frozen soybean paste in the refrigerator overnight before using it.
