Xiang (Crystal) Yang, Ph.D.

Assistant Professor; Meat Scientist, Department of Animal Science
Dr. Yang’s research interests include the evaluation and validation of new antimicrobial chemicals and interventions against foodborne pathogens, as well as the investigations of the influence meat safety strategies, have on the quality and shelf-life of meat products. In addition to applied investigations of meat safety, I also plan to continue my research characterizing the degree of antimicrobial resistance, pathogen and whole microbial community profiles present in different meat and poultry production chains in order to gain a more comprehensive understanding of how pathogens and bacteria interact with different food matrices using novel technologies, such as next-generation sequencing. Overall, the goal of our research is to continue to assist in industry efforts  to deliver highly safe, affordable meat that is high in quality and nutritional value to national and global consumers.

Research Interest:

My research interest in in pre and post harvest factors and their impacts on meat quality and shelf life. My previous research has evaluated the impact of various processing methods and feeding strategies on the quality and shelf life of poultry and beef.  My current research is evaluating the impact of different slaughtering and processing methods on the quality and shelf life of fish. I am also interested in researching the impact of feeding hemp by-products on the quality, shelf life, and safety of beef.
