What are the visible signs that sundried tomatoes have gone bad?
Visible signs that sundried tomatoes have gone bad include mold, yeast, or fungus growth on the surface. Check for any white, green, or black patches, which can be a clear indication of spoilage. Additionally, if the tomatoes have become slimy or develop an unusual texture, it’s best to err on the side of caution and discard them. Another visible sign is an off-color or discoloration, such as a darker or lighter shade than usual.

Check the packaging or container for any signs of damage or leakage, which can also contribute to spoilage. If you notice any of these visible signs, it’s best to discard the sundried tomatoes to avoid any potential health risks.
How can I determine if sundried tomatoes have gone bad based on their smell?
The smell of sundried tomatoes can be a good indicator of their freshness. Fresh sundried tomatoes typically have a rich, intense tomato aroma. If they have gone bad, they may emit a sour, unpleasant, or vinegary smell. If you notice a strong, pungent odor that’s different from the usual tomato smell, it’s likely that the tomatoes have spoiled.
When checking the smell, make sure to inspect the tomatoes in a well-ventilated area to avoid any confusion with other nearby odors. If you’re still unsure, compare the smell of the sundried tomatoes to a fresh batch or a newly opened package. This will help you determine if the smell is normal or a sign of spoilage.
