How we tested spoilage

We tested spoilage in commercially packaged cake mix by storing both unopened and opened samples in our pantry at room temperature for 30 days beyond the expiration date. After this period, we examined the opened mix for any signs of mold growth, off smells, or unusual discoloration. The texture was also assessed, noting any clumping or changes in consistency. We recorded our observations meticulously, and for verification, we heated a small portion of the opened mix to 165Β°F/74Β°C to check for any off flavors. Ultimately, we discarded any samples that showed signs of spoilage, prioritizing safety above all.
