Discovery Park Undergraduate Research Internship Program

"METABOLOMIC PROFILES TO UNDERSTAND THE EFFECT OF POSTMORTEM AGING ON COLOR AND LIPID OXIDATION STABILITIES OF DIFFERENT BOVINE MUSCLES"

About the Project

Project Time & Type:
Fall 2016 - DURI
Research area(s):
Animal/Food Science
Project Description:
Postmortem aging is extensively practiced in the meat industry mainly due to its beneficial impacts on eating quality attributes. However, depletion of antioxidant compounds during aging may lead postmortem muscles to be more oxidation susceptible, resulting in intensified discoloration and/or off-flavor development. Identifying key metabolites that are related to oxidative quality deterioration will provide critical insights for the industry to develop practical strategies to prevent oxidation-related quality defects. Therefore, the objective of this study is to identify key metabolites that could be associated with oxidation stabilities of aged bovine muscles by using a novel HPLC-MS based global metabolomics approach.
Expected Student Contributions:
Students will perform physico-chemical assays to determine meat quality measurement analyses under a close guidance of graduate students, a post-doc research associate, and project faculty advisors. The students are responsible for keeping accurate data records and conducting literature review. They are required to submit a mid-term progress report and the final report upon the completion of the study by the final week.
