2.Test Results
- Appearance: The water was separated and the caramel part was watery. In addition, caramel penetrated the pudding part, the container swelled, and gas was generated.
- pH: 6.6
- Functional inspection: As a result of a functional test by eight people, seven people felt a chemical odor (cleosote odor), and astringency remained in their mouths.
- GC-MS: Peaks of guayacol (2-metoxyphenol) and 2-ethoxyphenol were observed.
- Bacterial test: The genus Bacillus was mainly detected.
3.Conclusion
It was presumed that the pudding was poorly stored and bacteria proliferated, and the fragrances of the pudding, vanillin and ethylvanine, were decomposed, producing guayacol (2-methoxyphenol) and 2-ethoxyphenol, resulting in a chemical odor.
4.Reference
After investigating the sales situation, it was sold next to the refrigerated display case (room temperature).
