Summary

Grape processing significantly increases airborne particles, especially larger biological aerosols like bacteria and fungi. Particle levels rapidly return to normal after processing stops, indicating short-term airborne contamination risks.

Area of Science:

  • Environmental Science
  • Occupational Health
  • Food Science

Background:

  • Grape processing generates airborne particles, impacting indoor air quality.
  • Understanding particle size distribution and microbial content is crucial for risk assessment.

Purpose of the Study:

  • To quantify airborne particle formation during pre-fermentation grape processing.
  • To assess the contribution of grape handling to airborne microbial load.

Main Methods:

  • Laser particle sizers were used to measure particle numbers in four size classes.
  • Impactor and liquid impinger samplers collected airborne bacteria and fungi.
  • Flow cytometry analyzed the aerodynamic diameters of biological aerosols.

Main Results:

Related Experiment Videos

  • Grape handling increased total airborne particles sixfold, with a shift towards larger particle sizes (>5 microm).
  • Bacterial and fungal aerosols, primarily >5 microm, increased 150-fold.
  • Maximum concentrations reached 485,000 cfu/m³ for bacteria and 146,000 cfu/m³ for fungi and yeasts.

Conclusions:

  • Grape processing activities are a significant source of airborne biological and non-biological particles.
  • Larger airborne particles (>5 microm) are the primary carriers of microbial aerosols during grape handling.
  • Airborne particle concentrations decrease rapidly post-processing, suggesting transient occupational exposure.
