How we tested spoilage

We stored the unopened refrigerated tempeh at approximately 40°F (4°C) for seven days, closely monitoring it throughout the period. Upon opening the package, we noted a faint off smell and observed a slimy texture developing on the surface. The color remained mostly consistent, but we were cautious of any subtle changes. To verify its safety, we briefly heated a portion to 165°F (74°C) and noted that while the smell intensified, the texture remained unappealing. Given these observations, we decided to discard the tempeh, prioritizing safety and avoiding any questionable food products.
