In the Spotlight

USDA Secretary Tom Vilsack visits ERRC

Secretary Vilsack visited the Eastern Regional Research Center, NAA, ARS, USDA in Wyndmoor PA on Thursday, July 23, 2009 to review the Center’s pioneering research programs in sustainable bioenergy, food safety, and health-promoting foods.  Accompanying the Secretary was Deputy Undersecretary for Rural Development Cheryl Cook.  The Secretary addressed the entire Center staff at the end of the visit and thanked the staff for helping him achieve his objectives in rural development, sustainable agricultural bioenergy, obesity prevention, food safety and security and for making USDA effective and relevant “everyday and everyway.”

Good news for fans of raw cookie dough.  Researchers at ARS's Eastern Rgional Research Center (ERRC) in Wyndmoor, Pennsylvania, have filed a patent on technology that can further protect pasteurized liquid eggs from food safety threats.  These threats include both naturally occurring spoilage bacteria and pathogens such as Salmonella enteritidis, the primary cause of egg-related foodborne illness in the United States.  The technology has also been successfully applied to milk.

But don't go running for that dough just yet.  The U.S. Food and Drug Administration (FDA) still cautions against consuming any raw, unpasteurized eggs or products that contain them.

DPPRU Molecular Modeling Promotes Milk Protein Innovation

AlphaS2-Casein (AlphaS2-CN) comprises up to 10% of the casein fraction in bovine milk.  The role of AlphaS2-CN in milk and dairy products has not been studied in detail in part due to a lack of structural information on the molecule. Interest in the utilization of this molecule in dairy products and nutrition has been renewed by work in three areas: biological activity via potentially biologically active peptides, functionality in cheeses and products, and nutrition in terms of calcium uptake. To help clarify the behavior of AlphaS2-CN in its structure-function relationships in milk and its possible applications in dairy products, ERRC scientists have produced a working three dimensional (3D) molecular model for this casein (J. Dairy Science92:1338, 2009).  This effort completes the work on molecular modeling of the caseins.  Molecular models for this protein and for the other three major caseins (AlphaS1-CN β-CN and κ-CN) in pdb format may be downloaded from the DPPRU site.

Dairy Team-Up Leverages Research Towards Healthy Ingredients

Dairy Management Inc., the National Dairy Council, and the Department of Defense Combat Feeding Program-Natick Soldier Research, Development and Engineering Center, have partnered with USDA-ARS on a new National Dairy Research Plan, a roadmap for dairy research.  The researchers of the Dairy Processing and Products Research Unit, USDA/ARS/ERRC, will collaborate to develop new milk ingredients, new technologies that enhance the health, safety and functionality of dairy products, and on methods to extend shelf-life.

ERRC Scientists Partners in Successful Development of New Method for Biodiesel Production from Non-Food Feedstock

As the use of biodiesel, the renewable and domestically produced replacement for petroleum diesel fuel, expands worldwide, new feedstock supplies are needed to meet increasing demand.  The use of low cost starting materials is particularly interesting, since feedstock cost can constitute 80% of overall production cost when high value, edible fats and oils are used to produce biodiesel. Working in collaboration with BlackGold Biofuels, ERRC researchers have contributed to the successful development of a robust production process that converts trap grease, a low-value waste fat, to high quality biodiesel.  The accompanying article describes the announcement by the city of San Francisco, CA of its issuance of a contract to BlackGold for the first production scale implementation of its technology.

Go Native with this Promising Biofuel - and Biomedical - Crop

Guayule (K1559-3)

Perhaps the single most valuable gift the desert-dwelling guayule plant offers us is its superb natural latex. The white, rubber-rich substance, extracted and purified from this southwestern U.S. native shrub (Parthenium argentatum), is ideal for making high-quality gloves, medical devices, and other in-demand natural rubber products.

Importantly, latex from guayule (pronounced why-YOU-lee) is free of the proteins responsible for the sometimes-deadly latex allergies caused by the most widely used natural-rubber source, the rubber tree, Hevea brasiliensis.

But guayule may also prove to be an economical, environmentally friendly source of yet another prized commodity: energy. That energy can be made from the ground-up stems and branches, called “bagasse,” that are left after their latex has been removed.
