How Long Does Wasabi Last?

How long does wasabi last? The shelf life of wasabi depends upon how the product was prepared, purchased and the best by date. Real wasabi comes from the root of a plant that is very expensive because it is delicate and hard to grow. It is only grown along riverbeds in Japan.

How to tell if Wasabi is bad, rotten or spoiled?

Practicing proper hygiene and food safety techniques will help prevent foodborne illness.

Does wasabi go bad? If wasabi root has gone bad it will become soft and mushy, which is easier to see with fresh than in its other forms.

A common trait of wasabi paste going bad is a separation of liquid (you squeeze the tube and get a burst of liquid instead of paste). Whether it is roots, paste or powder - discard the product if there is a foul odor, change in appearance or as always if any mold is present.

The peas will loose their crunch when going bad and just become stale.

There are, of course, certain health risks associated with spoiled foods so always remember to practice food safety and enjoy your foods before their shelf life has expired!

How to store Wasabi to extend its shelf life?

Wasabi root should be stored in a moist paper towel in the refrigerator, rinsing the root with cold water again every few days. Wasabi paste and powder should be stored in a cool dark pantry until opened. Once open, wasabi paste should be stored in the fridge to extend its shelf life. Wasabi peas should remain in the pantry either with their bag re-sealed or transferred to an airtight container.

Some benefits of proper food storage include eating healthier, cutting food costs and helping the environment by avoiding waste.
