Associate Professor

Research Emphasis: Grain Processing Engineering

The focus of Dr. Atungulu's research is to engineer effective strategies to maintain grain (rice, corn, soybean and grain-sorghum) quality and prevent mycotoxin development, especially in on-farm, in-bin drying and storage systems. 

Current Research Projects:

  1. Prevention of mycotoxin development and quality degradation in rice during on-farm, in-bin drying and storage
  2. Reducing aflatoxin contamination of corn in on-farm bin drying and storage systems
  3. Development of effective strategies for simultaneous drying and decontamination of corn to maintain quality and prevent mycotoxin
  4. Improving germination rate of soybean seed dried using recently introduced in-bin drying systems

Research Emphasis: Food Production Sustainability

The mission of the Food Processing program is to reduce the environmental impact of food processing by using green technologies, the development of new uses for byproducts and co-products of the food industry, and novel uses of agricultural commodities.

Current research projects:

  1. Utilization of grain sorghum as a feedstock for the production of lactic acid, a precursor of polylactate, and a feed ingredient specifically designed for aquaculture.
  2. Production of enhanced soybean meals with low antinutritional factors by solid state fermentation

Dr. Terry Siebenmorgen
Distinguished Professor

Research Emphasis Area: Rice Processing

Dr. Siebenmorgen leads the University of Arkansas Rice Processing Program whose multidisciplinary team conducts both basic and applied research in pre-harvest property characterization, drying, storage, milling, and end-use quality assessment.

Current research projects:

  1. Quality of rice produced using alternative flooding practices.
  2. Effects of airflow rates on milling yields, throughput. and energy utilization in commercial rice driers.
  3. Impacts of rough rice thickness grading prior to milling on milling yields/quality.
  4. Measuring fissure formation rates in rough rice during drying using an x-ray system.
