Target Audience:Hemp seed protein, an underexploited resource, is nutritious and highly digestible, but information on its structural and functional properties is needed by food manufacturers, processors, and fumulators to expand utilization. Such information may be of value also for agronomists and plant breeders Changes/Problems:We discovered that freeze-drying the processed hemp seed protein is a signifcant limitation in sample preparation. Each sample takes days to completely freeze-dry due to large volume (about 500 mL). Special handling of the samples is necessary to avoid melting. Only a few preparations can be freeze-dried. simultaneously to avoid overloading the freezedrier system. What opportunities for training and professional development has the project provided?• Student training: 1 undergraduate student assisted in conducting experiments • One part-time research technician was hired How have the results been disseminated to communities of interest?One paper was published in a peer-reviewed scientific journal. Two presentation were made by student research assistants at the 2022 Association of 1890 Research Directors biennial conference What do you plan to do during the next reporting period to accomplish the goals?• High hydrostatic pressure (HHP) will be used to treat hemp heart protein isolate. Physicochemical, functional, and structural properties of treated protein will be evaluated relative to untreated isolate to determine the effectiveness of HHP for modification of protein characteristics to potentially expand the utility of hemp heart protein for food applications.
Impacts
What was accomplished under these goals?
Contact was made with a commercial producer of hemp heart protein and hemp protein preparations were obtained fromthe same. • Physicochemical, functional, and structural properties of commercially available hemp heart protein, an underexploited "novel" protein resource, were made in comparison to other commercially available plant and animal proteins to establish baseline characteristics. Physicochemical properties included color, proximate and amino acid compositions, and molecular weight profiles. Functional properties included water and oil holding capacities, emulsification activity and stability, foaming capacity, and solubility. Secondary protein structure was evaluated from deconvolved Amide I band spectra. Tertiary structure was evaluated using surface hydrophobicity and free-sulfhydryl content. • One paper was published and two student presentations at a national convention were made.
