Expiration & Storage Tips
When does shirataki noodle expire?
Unopened, shirataki noodles can last up to a year as long as they're kept in a cool, dark place. Even though manufacturers print a 'best by' date on the packages, this date can be treated more as an indicator for 'best quality', not 'safety'. So they can still be safe for consumption once the date has passed if they have been stored properly. Once opened, shirataki noodles need to be refrigerated in fresh water within an airtight container, where they can last up to seven days. Shirataki noodles tend to harden and dry out when frozen, so it isn't a recommended method of storage.
How do you tell if shirataki noodle is bad?
There are a few clear signs to help you determine if your shirataki noodles have gone bad. First, give them a good sniff. If they have developed a sour, rotten or off smell, it's best to throw them away. Next, look out for changes in color or texture. If they've turned yellow or appear excessively slimy, it might be time for them to go. Lastly, any visible mold is a definite sign they have spoiled.
Tips for storing shirataki noodle to extend shelf life
• Always store unopened packets of shirataki noodles in a cool, dark, and dry place away from heat. The pantry or kitchen cabinet could work well.
• Once opened, transfer the noodles to an airtight container filled with clean water. Make sure to refrigerate them and use within seven days.
• Change the water in the container every couple of days to keep the noodles fresh.
• Avoid freezing shirataki noodles as this could negatively affect the texture.
• Lastly, always trust your senses. If the noodles smell bad, have changed color, or appear excessively slimy, it's most likely time to toss them out.
