Hypothesis
What is the occurrence of ochratoxin A in musts, wines, and dried vine fruits from grapes harvested in Argentina?
Conclusion
The study found low levels of ochratoxin A in musts and wines, but a significant contamination in dried vine fruits.
Supporting Evidence
- Ochratoxin A was found in 60% of dried vine fruit samples.
- Only 9% of must samples showed ochratoxin A contamination.
- The mean levels of ochratoxin A in must and wine were low at 0.12 ng/mL and 0.37 ng/mL, respectively.
Takeaway
This study looked at a harmful substance called ochratoxin A in grapes and wines from Argentina, finding it mostly in dried fruits.
Methodology
The study evaluated ochratoxin A levels using immunoaffinity columns for extraction and high-performance liquid chromatography for detection.
Limitations
The study's findings may not be generalizable due to the limited number of samples from certain regions.
