How we tested spoilage

We stored our opened refrigerated tempeh at approximately 40°F (4°C) for a total of five days, closely monitoring it for signs of spoilage. During this period, we observed changes in smell, noting a sour odor developing by day three, which was concerning. The texture began to feel slightly slimy, and by the fifth day, we detected some small patches of mold on the surface. To verify its safety, we briefly heated a portion to 165°F (74°C) but ultimately decided to discard all samples, as the changes indicated spoilage, prioritizing food safety above all.
