In a rustic-looking garden on the UC Davis campus recently, two dozen young leaders from sub-Saharan Africa viewed simple, low-cost innovations that can reduce postharvest losses, increase food safety and preserve nutritious food in their home countries.
Advances in breeding and postharvest handling in strawberries and tomatoes, aimed at reducing the costs of disease in the field and in postharvest, were on display at the recent Strawberry Disease Field Day, hosted by the UC Davis Strawberry Breeding Program.
Growers often harvest tomatoes before they ripen in hopes of extending shelf life and avoiding crop loss. But that act of removing the fruit from the vine affects flavor. And, storing tomatoes below certain temperatures also hurts quality and shelf life.
New research published this month out of the University of California, Davis, examined changes in tomatoes at the molecular level to better understand what happens during postharvest handling and cold storage.
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.
You come home from the store with a bunch of bananas. Now, which is the better place to store them, on the counter or in the fridge? Storing fresh produce correctly can save you money and time by keeping your tomatoes, grapes, broccoli and other fresh fruits and vegetables in tip-top condition for as long as possible.
Cooling vegetables just after harvest prolongs shelf life and maintains quality. Most California vegetables are precooled before shipment using Cold air, Cold water, Ice, and/or Vacuum. Several of these were developed at UC Davis in the 1970s and 1980s in Plant Sciences, and in Biological and Agricultural Engineering.
Small growers can build their own farm-scale coolers at a fraction of the cost of conventional units, thanks to the invention of a device that adjusts air conditioners to drop the temperature all the way down to refrigeration levels.
