Post Harvest Handling

“Advancing Onion Postharvest Handling Efficiency and Sustainability by Multimodal Quality Sensing, Disease Control, and Waste Stream Management”

Project Director – Dr. Changying “Charlie” Li at cyli@uga.edu

[Supported in Part by USDA-NIFA-SCRI Project No. 2009-02520]

 

Goal: Enhance onion postharvest handling efficiency and sustainability by integrating more efficient online sorting, reducing storage losses, and managing the waste stream of onions in relation to the following objectives:

  • Enhance the efficiency of onion quality sorting by a multimodal sensing platform using X-ray and hyperspectral imaging technologies.

 

  • Develop a gas sensing and tracing method for disease detection in storage and evaluate onion postharvest disease management practices.

 

  • Manage the onion waste stream and mitigate environmental pollution using an anaerobic digestion system.

 

  • Evaluate social implications and economic impacts of these technologies.

 

  • Engage in outreach and technology transfer with stakeholders.
