It’s not always easy to find silver linings during the COVID-19 pandemic, but here’s one that food scientists at the University of California, Davis, have discovered: More people are exploring the ancient art of fermented foods.

“My mom made her first batch of sauerkraut this summer,” said Maria Marco, a microbiologist and food science professor with the UC Davis College of Agricultural and Environmental Sciences. “With so many of us sheltering-in-place, fermented foods are more popular than ever.”

Consumer demand is rising for all things avocado, including oil made from the fruit. Avocado oil is a great source of vitamins, minerals and the type of fats associated with reducing the risk of heart disease, stroke and diabetes. But according to new research from food science experts at the University of California, Davis, the vast majority of avocado oil sold in the U.S. is of poor quality, mislabeled or adulterated with other oils.

In California, fermented foods and beverages are especially trending with young people, and food safety specialist Erin DiCaprio said information is in demand.

“I get calls every day from people asking things like, ‘There’s a white film on top of my sauerkraut. Is it still safe to eat?’” DiCaprio said.

Do you know why it’s called iceberg lettuce? In 1926, Bruce Church—University of California graduate, farmer and founder of Fresh Express—developed a way to get his head lettuce from Salinas to the East Coast by loading the freshly-harvested crop in train cars and covering it with ice. As the lettuce-laden cars rolled into stations, folks would call out, “The icebergs are coming, the icebergs are coming.”

After providing 29 years of service, UC Cooperative Extension Specialist and Associate Agricultural Experiment Station Dean Dave Campbell retires July 1. Long-time colleague Rose Hayden-Smith asked Dave to reflect on his career and offer advice for those rising in the academic ranks.

A researcher from the University of California, Davis, is seeking to commercialize equipment that could be used as an early warning device to detect a deadly disease in citrus long before trees show signs of infection.

A new breed of ranchers is bringing diverse demographics and unique needs to rangeland management in California. These first-generation “ranchers” are often young, female and less likely to, in fact, own a ranch. But like more traditional rangeland managers, this new generation holds a deep love for the lifestyle and landscapes that provide a wealth of public benefit to California and the world.

When it comes to watering walnuts, most California growers believe you need to start early to keep trees healthy and productive throughout the long, hot summer. But according to striking results from a long-term experiment in a walnut orchard in Red Bluff, California, growers can improve crop production if they hold off irrigation until later in the season and directly measure their trees’ water needs.

Art Bowman has been growing almonds in Modesto for more than 40 years. He stays up-to-date on the latest science and invests in technology that keeps his farming sustainable. He uses precision technology to apply nitrogen, for example, that essentially spoon-feeds water and nutrients to his trees.

“Our yields have increased quite a bit since we switched to precision application,” says Bowman, adjusting his hat against the noonday sun. “And that’s without adding any extra nitrogen. That’s huge.”

South of Merced, under the hot summer sun of the San Joaquin Valley, Miguel Guerrero of The Wine Group is trying a new high-wire act. In collaboration with UC Davis Cooperative Extension, Roduner Ranch vineyard manager Guerrero is experimenting with Cabernet Sauvignon vines and other varieties elevated by a single wire at 66 inches—plantings that are 2-to-3 feet higher than the traditional wine grape canopy.
