I found a sealed box of Dashi powder (Dashi No Moto) with an expiration date of September 2015 (more than 7 years ago).

Is it safe to use it?
If not, maybe there something else I can do with it, before throwing it out?

Thanks

  1. There has been a lot of [reporting](https://www.nytimes.com/article/expiration-dates-coronavirus.html) [lately](https://one.npr.org/?sharedMediaId=1111850221:1111850921) that expiration dates have little connection to food safety, and more about getting people to replace products with new ones.

    I think you need to take it case by case and try the food, but (and is an assumption because I couldn’t find any info on the actual process online) an industrially dehydrated or freeze dried product like this is likely shelf stable for a very long time.

    That being said, 7 years is a long time, lol.

    It might be safe. It might not.

    At any rate, a sealed box would, I suspect, be okay to use after, say, a year. It might not have the full flavor of a more recent box, but it likely wouldn’t cause any harm.

    *Seven* years, though… *I* wouldn’t take the chance, myself. I’d dump it.
