GAINESVILLE, Fla. — A University of Florida scientist has moved one step closer to his goal of eliminating 99.9 percent of peanut allergens by removing 80 percent of them in whole peanuts.
Scientists must eliminate peanut allergens below a certain threshold for patients to be safe, said Wade Yang, an assistant professor in food science and human nutrition and member of UF’s Institute of Food and Agricultural Sciences.
If Yang can cut the allergens from 150 milligrams of protein per peanut to below 1.5 milligrams, 95 percent of those with peanut allergies would be safe. It’s challenging to eliminate all peanut allergens, he said, because doing so may risk destroying peanuts’ texture, color, flavor and nutrition. But he said he’s using novel methods like pulsed light to reach an allergen level that will protect most people.
Yang, whose study is published online in this month’s issue of the journal Food and Bioprocess Technology, cautioned that he has done peanut allergen experiments only in a laboratory setting so far. He hopes to eventually conduct clinical trials on animals and humans.
GAINESVILLE, Fla. — University of Florida researchers are turning to the old-fashioned method of steaming to help treat citrus greening, a disease devastating citrus trees throughout Florida.
Reza Ehsani and his UF Institute of Food and Agricultural Sciences colleagues are tenting and then enveloping trees in steam that is 136 degrees Fahrenheit for about 30 seconds in an attempt to kill the citrus greening bacterium. (more …)
GAINESVILLE, Fla. – A University of Florida-developed web tool can bring growers $1.7 million more in net profits over 10 years than a calendar-based fungicide system because it guides growers to spray their crop at optimal times, a new UF study shows.
The Strawberry Advisory System, devised by an Institute of Food and Agricultural Sciences researcher, takes data such as temperature and leaf wetness and tells growers when to spray fungicide to ward off diseases. Growers can use the system by logging onto www.agroclimate.org/tools/strawberry or use the website to sign up for email or text alerts.
Before the system was developed, strawberry farmers traditionally sprayed weekly during the November-to-March growing season. Spraying more often than is needed wastes money and can lead to fungicide resistance, said Natalia Peres, associate professor in plant pathology, who led the system’s development.
Not all strawberry growers use the system, but this research might persuade them to do so, said Tatiana Borisova, an assistant professor in UF/IFAS food and resource economics department.
From farm gate to dinner plate, consumers are looking for more local food options. According to the latest USDA Census of Agriculture, industry estimates put local food sales at $7 billion in 2011, reflecting the market’s growing importance.
A revamped online tool, called Florida Food Connect, at www.floridafoodconnect.com, offers agricultural producers an easy-to-use way to reach new customers and offers consumers an easy way to find local growers of the freshest foods.
Florida Food Connect offers large and small producers and growers opportunities to diversify sales and build profitable relationships.

GAINESVILLE, Fla. – A University of Florida-created model may help growers plant at optimal times and avoid crop-destroying drought, which can cost millions of dollars in a given year, according to one of the tool’s creators.
If growers know when their crops need the most water, they can plant accordingly, said Keith Ingram, an associate scientist in UF’s agricultural and biological engineering department, part of the Institute of Food and Agricultural Sciences.
Although forecasts indicate a drought’s likelihood, they aren’t perfect, Ingram said. But they can help a farmer decide whether to plant a crop earlier or later than usual so drought is less likely to occur when the crop is most sensitive to drought, Ingram said.
GAINESVILLE, Fla. –Scientists and growers can use a new genome database developed in part by University of Florida researchers to help make fruit trees more disease- and pest-resistant and enhance crop quality.
Researchers who study citrus, rosaceae and vaccinium crops will be the primary users of the portal, said Mercy Olmstead, assistant professor of horticultural sciences at UF’s Institute of Food and Agricultural Sciences, but agricultural producers will also reap the benefits.

GAINESVILLE, Fla. — The contraption seems so simple, yet so clever, like something The Professor might have concocted on “Gilligan’s Island.”
Researchers at the University of Florida’s Institute of Food and Agricultural Sciences have devised a bedbug trap that can be built with household items. All you need are two disposable plastic containers, masking tape and glue, said Phil Koehler, UF/IFAS urban entomology professor. The traps catch and collect the bugs when they try to travel between people and the places where bedbugs hide, he said.
“This concept of trapping works for places where people sleep and need to be protected at those locations,” Koehler said.

LAKELAND, Fla. – While most people think of unmanned aircraft solely as military drones, a group University of Florida Institute of Food and Agricultural Sciences researchers know from more than a decade of experience that the small aircraft are used to further science and engineering.
Thanks to an invitation from the Federal Aviation Administration, the University of Florida’s Unmanned Aircraft Systems Research Program will be at this week’s 40th annual SUN ’n FUN Fly-In in Lakeland, the nation’s second-largest airshow, to discuss the UF program, its history, and its interdisciplinary design and research, (more …)
GAINESVILLE, Fla. – A new University of Florida web-based tool worked well during its trial run to measure water consumption at farms in four Southern states, according to a study published this month.
The system measures the so-called “water footprint” of a farm. In the broader sense, water footprints account for the amount of water used to grow or create almost everything we eat, drink, wear or otherwise use.
Researchers at UF’s Institute of Food and Agricultural Sciences introduced their WaterFootprint tool in the March issue of the journal Agricultural Systems, after using it to calculate water consumption at farms in Florida, Georgia, Alabama and Texas.

GAINESVILLE, Fla. – University of Florida researcher Jeffrey Brecht is leading a team of scientists working to eliminate waste and streamline the process of distributing the U.S. Army’s legendary Meal, Ready-to-Eat (MREs).
In a five-year, $6.7 million study, Brecht, the director of the UF Institute of Food and Agricultural Sciences’ Research Center for Food Distribution and Retailing, and colleagues tested the longevity of MREs, along with First Strike Rations (FSRs) for front-line troops, including special forces.
“These rations were originally developed with a shelf life of three years for MREs and two years for FSRs – but at 80 degrees,” Brecht explained. “However, when they send them to the Middle East, they could be exposed to temperatures as high as 140 degrees, at which point the shelf life could be 4 weeks or less, instead of the three years.” (more …)
