Plan and conduct research to develop methods for isolation, modification of alfalfa proteins, and adaptation in food products and edible food packaging as well as ingredients for cosmetic products.
Isolate and modify proteins and other components from raw feedstock and/or from industry crop processing byproducts.
Develop new uses for, and new knowledge of, proteins derived from agricultural crops and co-products.
Characterize alfalfa proteins in their native state, and modify them by applying chemical, physical, enzymatic, or other techniques to impart desired functionalities.
Develop a fundamental understanding between processing and extent of modification, and subsequent characterization of modified products to understand the performance relationships between process parameters, structure, and functionality.
Obtain fundamental information on degradation under different deleterious conditions and other physical and molecular properties.
Study generated protein isolates for their functional properties and performance in targeted applications.
Use methods and state of the art instrumentation, such as nuclear magnetic resonance spectroscopy, infrared spectroscopy, ultraviolet/visible spectroscopy, circular dichroism, differential scanning calorimetry, and size exclusion chromatography.
Apply the principles of Life-Cycle Assessment (LCA) or similar framework to quantitatively assess the environmental and economic sustainability of developed renewable products or technologies and potential benefits.
Investigate physical processing methods such as milling, steam jet-cooking, and extrusion, as well as enzymatic methods to deflavor isolated protein fractions.
Develop a stakeholder base to advocate for enhancing research and enable commercialization of products to meet mandated technology transfer objectives.
