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.
