Postharvest Center: New research focus and outreach

Still providing the world with top-notch information

UC Davis has been a leading source of information for people handling, packaging and transporting crops since the beginnings of the Postharvest Research and Extension Center in 1979. Now, the center is strengthening its focus on the needs of industry, offering fresh courses, weaving strategic partnerships and expanding into digital media, all while building up its research capacity to better serve the needs of the produce industry.

“We're asking people in the industry, ‘How can we support you? How can we better listen to you?' We want people to know we're not disconnected know-it-alls,” said new center co-director Bárbara Blanco-Ulate, an associate professor in the UC Davis Department of Plant Sciences. “We're getting more faculty involvement, people with expertise in related fields such as quality engineering and safety, as well as bringing in emeriti faculty and people from around California. We're forming partnerships with organizations around the world, and we've opened up to people from other institutions around the country.”

“The larger the network, the more things we can do,” added fellow co-director Irwin R. Donis-Gonzalez, an associate professor of UC Cooperative Extension in the Department of Biological and Agricultural Engineering.

The foundation: Expanded research

The new co-directors will beef up the center's applied science component with the hiring of a research specialist. They aim to provide new information that can be used industry-wide as companies explore new ways to handle and store fresh produce.

“We're building the capacity to respond to industry requests for research,” Blanco-Ulate said.

New courses, national reach

Their first workshop, held recently, demonstrates the center's renewed vision and commitment to broad networking: The Agricultural Water Systems Workshop addressed current concerns around water management and risks to food safety. Partners in the course included the Western Growers Association, the University of Arizona, the University of Florida and Salinas-based Taylor Fresh Foods, Inc.

Courses given over the past several years that have been recorded will be posted to the center's new, online video library and to the center's YouTube channel.

“People can watch those courses for free,” Blanco-Ulate said. In addition, new courses will be offered in-person and hybrid.

The co-directors are working with the University of California to offer continuing and professional education credits to course participants.

Online resources – many for free!

The center's website features a database with scores of free product fact sheets, which are downloaded by users around the world. The fact sheets are so highly regarded that they are considered expert evidence in legal proceedings, Blanco-Ulate said. Visitors to the website can also find links to research papers published by UC Davis faculty, including seminal works by Adel Kader, who founded the center.

Books are offered through the center's online bookstore and include titles through UC Agriculture and Natural Resources. Ten new titles are being planned, including topic-specific updates taken from previous classics.

Debunking myths: Ethylene

A new newsletter deals with a new problem: Misinformation about food and food handling that spreads through social media. One example is the use of ethylene to ripen produce such as bananas, so that they can be safely stored until ready for the consumer.

“Ethylene is safe for humans and does not leave any harmful residue on produce,” Donis-Gonzalez wrote in the center's latest newsletter. Even better news, he added: The levels of ethylene used on food are a tiny fraction of the concentrations that would be needed to create an explosion, one of the false alarms being raised in social media.

Evolving with the times

After 47 years of service, these and more updates will keep the center at the forefront of an evolving postharvest world. The top goal: Meet the needs of agriculturalists, industry and consumers.

“We are adapting to new needs, with both the resources and the workshop we're offering,” Donis-Gonzalez said.

“As a land-grant institution, we take our outreach mission seriously,” Blanco-Ulate added.

UC SAREP funds 8 sustainable food and farming projects

 

Projects will support socially disadvantaged farmers, increase urban access to healthy food and more

The UC Sustainable Agriculture Research & Education Program (SAREP) is pleased to announce the recipients of the Sustainable Agriculture and Food Systems 2024-25 Small Grants Program. This grant program will fund planning, research and education projects that support the development of sustainable community food systems and environmentally sound and economically viable farming enterprises.  

Of the 33 eligible applications, eight applicants were selected to receive approximately $80,000 in combined funding to support their work. Individual grants are limited to $10,000. “The Small Grants Program is an important part of our mission,” said Ruth Dahlquist-Willard, interim director of UC SAREP. “By facilitating these grants, SAREP is able to support ANR in engaging a wide range of food systems stakeholders, outcomes show that a small financial investment can have a large impact in improving the lives of Californians.”

The eight recipients of this year's grants are:

Planning

Building Capacity and Resiliency Among Networks of Socially Disadvantaged California Farmers

Fresh Approach will establish a network of pooled learning and technical support that will aid emerging food-aggregation businesses in accessing sustainable market channels, including emergency food distribution. As part of the project, they will enhance an interactive GIS mapping tool of value chains to streamline market opportunities for socially disadvantaged farmers and aggregators. (Project lead: Andy Ollove, Fresh Approach)

Sustainable Urban Resident Food Gardens Expansion Planning Project

Growing Hope Gardens will systematize the process of outreach, discovery, design, planning and implementation in creating new urban resident food gardens. The project will document Growing Hope Gardens' garden development process into a training and implementation manual to more effectively duplicate food garden programs in more low-income urban communities.
