Hypoallergenic peanuts developed by N.C. A&T licensed for use in food products, immunotherapy

Hypoallergenic peanuts, peanut butter, and other peanut products are a step closer to grocery stores with the signing of an exclusive licensing agreement for the patented process that reduces allergens in peanuts by 98 percent.

N.C. A&T signed the agreement with Xemerge, a Toronto-based firm that commercializes emerging technologies in food, agriculture, and a variety of other fields. Xemerge has opened an office at the Gateway University Research Park south campus in Greensboro.

“This is one of the best technologies in the food and nutrition space we have seen,” said Johnny Rodrigues, Chief Commercialization Officer of Xemerge.

“It checks all the boxes: non-GMO, patented, human clinical data, does not change physical characteristics of the peanut along with maintaining the nutrition and functionality needed, ready for industry integration from processing and manufacturing to consumer products.”

The process was developed by Dr. Jianmei Yu, a food and nutrition researcher in A&T’s Department of Family and Consumer Sciences, and two former A&T faculty members, Dr. Mohamed Ahmedna and Dr. Ipek Goktepe, both of whom are now at Qatar University.

“Treated peanuts can be used as whole peanuts, in pieces or as flour to make foods containing peanuts safer for many people who are allergic,” Dr. Yu said.

“Treated peanuts also can be used in immunotherapy,” she said. “Under a doctor’s supervision, the hypoallergenic peanuts can build up a patient’s resistance to the allergens.”

Research funding was provided by the Agriculture and Food Research Initiative of the U.S. Department of Agriculture.

Sen. Hagan listens to Wayne Szafranski of A&T in the Engineering Research Center’s  Material Processing and Characterization Lab.

U.S. Sen. Kay Hagan is promoting innovation at historically black universities, and on Monday she brought the news media to N.C. A&T for a close-up look at what she’s talking about.

Accompanied by a group of national and local reporters and, photographers, and videographers, Sen. Hagan toured the NSF Engineering Research Center for Revolutionizing Metallic Biomaterials and then held a news conference to talk about her bill to create a Historically Black Colleges and Universities (HBCU) Innovation Fund.

The Engineering Research Center is developing an advanced magnesium alloy to make screws, plates, and other implantable devices that could hold broken or surgically repaired bones in place for healing and then dissolve and pass out of the body when they’re no longer needed.

The technology could eliminate the need in many cases for either surgical removal or for patients to carry metal parts in their bones for a lifetime.

Sen. Hagan was joined in her news conference by Chancellor Harold L. Martin Sr. and two A&T bioengineering grad students, Adrienne Daley and Roman Blount.

Speaker: Dr. George W. Huber, Professor of Chemical and Biological Engineering, University of Wisconsin-Madison

Dr. Huber’s research focus is on breaking the chemical and engineering barriers to lignocellulosic biofuels.  He is the co-founder of Anellotech, a biofuel company focused on commercializing catalytic fast pyrolysis, a new technology developed by Dr. Huber’s research group to convert biomass into gasoline-range aromatics.  His discovery of Raney-NiSn catalyst for hydrogen production from biomass-derived oxygenates was named as one of top 50 technology breakthroughs of 2003 by Scientific American.

Abstract: This presentation discuss different approaches for the production of renewable fuels and chemicals that are being developed in the Huber research group.  The presentation will highlight some of the challenges and future opportunities for future process development and design of new catalytic approaches.

Renewable aromatics and olefins can be produced from biomass by catalytic fast pyrolysis (CFP). The aromatics can be used as a feedstock to make renewable polymers including polycarbonates, polyurethanes, polystyrenes, and polyethylene terephthalates.

CFP involves the direct production of aromatics from biomass in a single catalytic step. Solid biomass is fed into a fluidized bed reactor, where the solid biomass thermally decomposes. The biomass vapors enter a zeolite catalyst, where a series of dehydration, decarbonylation and oligomerization reactions occur to form aromatics, olefins, CO, CO2, coke and water. Coke is formed from homogeneous decomposition reactions or catalytic reactions inside the zeolite.

Fundamental catalytic studies with model compounds combined with in-situ and temperature-programmed techniques have aided in the design of improved zeolite catalysts for CFP. Hydrodeoxygenation (HDO) is a platform technology used to convert liquid biomass feedstocks (including aqueous carbohydrates, pyrolysis oils, and aqueous enzymatic products) into alkanes, alcohols and polyols. In this process the biomass feed reacts with hydrogen to produce water and a deoxygenated product using a bifunctional catalyst that contains both metal and acid sites. The challenge with HDO is to selectively produce targeted products that can be used as fuel blendstocks or chemicals and to decrease the hydrogen consumption.
