Who Should Attend

Postharvest Short Course of Horticultural Crops
This course is a two-week intensive study of the biology and current technologies used for handling fruits, nuts, vegetables and ornamentals in California. It is designed for research and extension workers, quality control personnel in the produce industry, and business, government or academic professionals interested in current advances in the postharvest technology of horticultural crops.

It is particularly of interest to technical professionals responsible for quality assurance, research and extension activities related to fresh produce quality, safety and marketability. The lecture plus field trip option is limited to 50 participants, and the lecture-only option is limited to 45 participants. Enrollment will be handled on a first-paid, first-enrolled basis.


Topics included

  • An overview of the postharvest biology of horticultural crops
  • Maturity and maturity indices, measuring quality
  • Safety factors
  • Harvesting systems, preparation for market, packinghouse facilities and equipment, packaging, containers, and unitization
  • Cooling prior to shipment: methods, evaluation of efficiency
  • Storage: methods, facilities, equipment, management of environmental conditions including controlled atmospheres
  • Ethylene: treatments, exclusion and removal
  • Transport: systems, loading patterns, environmental control, use of modified atmospheres
  • Sanitation and other procedures related to decay and insect control; food safety assurance
  • Standardization and inspection, quality evaluation and control
  • Energy use in postharvest technology procedures
  • Harvesting and postharvest handling systems for various commodity groups
  • Marketing fresh produce: socioeconomic and environmental considerations
  • An overview of current postharvest research at the University of California

Short Course Format

The first week (Monday through Friday) is spent on intensive lectures and discussions as well as hands-on laboratory sessions on the UC Davis campus. The optional second week (Monday through Friday) is an extensive field tour covering a wide variety of postharvest operations. Facilities last year included selected packinghouses, cooling and storage facilities, produce distribution centers, field harvest operations, packing, and transportation facilities in various locations in central and coastal California. A prerequisite for attendance on the field tour is attendance at the first week of the short course. The tour’s first stop is in Sacramento, then the bus travels as far south as Bakersfield, continues west towards the Salinas and Monterey area, and then the final stops are in the San Francisco/Oakland area. The bus then returns participants to the UC Davis campus.

Week 1: Lectures + Labs on UC Davis Campus

Participants are responsible for their own housing (reservations and payment) during the first week of the course.

Davis has a fine selection of lodging options available. Please see the Yolo County Visitors' Guide for more information. The accommodations within easy walking distance of the campus are:
