Expiration & Storage Tips
When does seitan expire?
Unopened, store-bought seitan can last from its production date until the 'Best Before' date marked on the packaging, which is typically about a year. Once opened, it should be consumed within 3-5 days if refrigerated, to ensure freshness and prevent potential spoilage. Homemade versions similarly need to be eaten within a week due to lack of preservatives found in commercial products. Seitan can also be frozen, in which case it maintains its quality for up to 3 months.
How do you tell if seitan is bad?
Like many foods, seitan will show tell-tale signs when it's past its prime. Firstly, there might a strange, unusual smell that's different from its normal, neutral, yeast-like aroma. Secondly, discoloration or spots of mold can indicate spoilage - generally, its color should be beige or brown (depending on the marinade), so watch out for anything that deviates from that. Lastly, another sign can be an off-taste, so if you're uncertain, it's best err on the side of caution and discard it.
Tips for storing seitan to extend shelf life
• Always store seitan in a refrigerator, at a temperature below 40°F (5°C)
• If opened, keep the seitan submerged in its broth in a closed container to help maintain its moisture and taste. Drain and pat dry before use.
• For freezing, it's better to portion out and freeze in separate, meal-sized amounts to avoid having to thaw and refreeze.
• When thawing frozen seitan, it's best to place in a refrigerator overnight. Still got that thawing urgency? Submerge the sealed bag in cold water. Heating directly from frozen is last resort since it can potentially affect its texture.
