How we tested spoilage

We tested spoilage of opened commercially bottled French salad dressing that we stored in our pantry at around 70°F (21°C). After holding the sample for 30 days, we observed it for signs of spoilage such as ingredient separation, off odors, and any visible mold growth. The dressing exhibited some separation, but no mold was present, and the smell remained typical of its original scent. We also conducted a quick cook test by heating a small amount to 165°F (74°C) to check for any changes in texture or odor. Ultimately, prioritizing safety, we discarded the dressing due to the separation and potential for spoilage.
