Research Impact

  • Meat and poultry primary and further processing.

  • Use of non-meat ingredients to enhance texture, acceptability, and yield of meat products (e.g., use of organogels, hydrocolloid gums, non-chloride salts, soy/dairy proteins).

  • Structure and function relationships within protein gel matrixes (using small and large deformation techniques, microscopy, X-ray).

  • Safety of processed meat products (e.g., inactivation of E. coli O157:H7 in dry fermented products; validation of critical control points to reduce Salmonella).
