University of California

Fruit Ripening & Ethylene Management

Spring 2021 Virtual Workshop

 

Who Should Attend

This workshop is intended for shippers, fruit handlers (wholesale and retail) and produce managers who are involved in handling and ripening fruits and fruit-vegetables. The workshop focuses on how to increase profits by reducing losses at the receiving end, and delivering ready-to-eat, delicious fruits and fruit-vegetables to the consumer.

Participating in this workshop is one way to earn credits towards completing the Produce Professional Certificate.

 

Format and Dates

 

Live Zoom Sessions Tuesdays and Thursdays 9-11:30am PDT, for 2 weeks starting April 13. In the week prior, participants will receive access to a set of pre-recorded presentations.

Study Week April 5; Live Sessions April 13 & 15
Study Week April 12; Live Sessions April 20 & 22

Sessions will be recorded if you are unable to participate at this time. They will be available for one week following the live session.

The interactive, virtual format will include pre-recorded video presentations, weekly live overview, highlights and Q&A sessions with instructors. Participants can submit questions during the study week and during the live sessions.

Arpaia, Mary Lu
As an extension specialist for subtropical fruit, I have both an educational and research program dealing with citrus and avocado postharvest handling. There are two areas related to subtropical fruit postharvest handling in which I conduct research.

The first deals with the role of preharvest management on postharvest fruit quality. A clearer understanding of orchard management’s role is needed to develop strategies that optimize the postharvest life of subtropical fruits. I therefore collaborate in multi-disciplinary projects that examine the role of irrigation, fertilization, plant growth regulators and pest management on postharvest fruit quality.

I also conduct research that examines the response of subtropical fruit to the postharvest environment including temperature during handling and ethylene exposure.  As part of this research effort we have incorporated the use of sensory science procedures to study the impact of handling practices on eating quality.
