opened jar (refrigerator)5-10 days
Signs of Spoilage
Visible mold growth (white, green, or black fuzzy spots) on the peppers or liquid surface, slimy or mushy texture, sour or fermented smell, cloudy liquid, or an 'off' taste.
How to Check
Visually inspect for any mold. Use a clean spoon to gently check the texture; it should not be slimy. Smell for any sour, yeasty, or unpleasant odors. If in doubt, it's best to discard.
Storage Tips
Always use a clean utensil to remove peppers. Keep the peppers submerged in their packing liquid/oil to prevent air exposure and mold growth. Tightly reseal the jar after each use. Discard if left at room temperature for more than 2 hours.
unopened jar (pantry)1-2 years (until 'best by' or 'expiration' date)
Signs of Spoilage
Bulging lid, leakage, visible mold growth within the jar (rare for properly sealed jars), cloudy liquid, or an 'off' smell upon opening.
How to Check
Visually inspect the lid for any bulging. Check for any signs of leakage around the lid or jar. Upon opening, a strong sour, yeasty, or foul smell indicates spoilage. The liquid should be clear, not cloudy.
Storage Tips
Store in a cool, dark place away from direct sunlight and heat. The 'best by' date primarily indicates quality, but severe signs like bulging lids are safety concerns (e.g., botulism risk) and should lead to immediate disposal.
frozen6-12 months
Signs of Spoilage
Significant freezer burn (dry, discolored patches) indicates a loss of quality, not necessarily spoilage. A strong 'off' smell upon thawing would indicate spoilage, though this is rare if properly frozen.
How to Check
Visually inspect for excessive freezer burn. After thawing, smell for any unusual or unpleasant odors. Texture may be softer after thawing, which is normal.
Storage Tips
Store in airtight freezer bags or containers. Remove as much air as possible to prevent freezer burn and maintain quality. Label with the date. Thaw in the refrigerator overnight or by running under cold water before use. Do not refreeze thawed peppers.
homemade (refrigerator)3-7 days
Signs of Spoilage
Visible mold growth, slimy texture, sour or fermented smell, or any unusual discoloration.
How to Check
Visually check for mold. Touch test for sliminess. Smell for any off-odors (sour, yeasty, foul).
Storage Tips
Store homemade roasted red peppers in a clean, airtight container. If storing in oil, ensure the peppers are properly acidified (e.g., with vinegar or lemon juice to a pH below 4.6) to prevent the growth of Clostridium botulinum, which can cause botulism. Unacidified peppers in oil are a high risk and should be consumed immediately or frozen. Always refrigerate promptly.
