THE EFFECT OF NATURAL ANTIMICROBIAL INGREDIENTS ON THE QUALITY OF ROAST BEEF AND OVEN ROASTED TURKEY by Ace F. VanDeWalle A THESIS Presented to the Faculty of The Graduate College at the University of Nebraska In Partial Fulfillment of Requirements For the Degree Master of Science Major: Animal Science Under the Supervision of Professor Dennis E. Burson Lincoln, Nebraska August, 2010 THE EFFECT OF NATURAL ANTIMICROBIAL INGREDIENTS ON THE QUALITY OF ROAST BEEF AND OVEN ROASTED TURKEY Ace F. VanDeWalle, M.S. University of Nebraska, 2010 Advisor: Dennis E. Burson This research evaluates the use of a buffered vinegar and lemon juice concentrate (LV) solution on the quality of restructured beef and turkey rolls. Two studies were conducted to evaluate processing and ingredient concentration. Beef and turkey rolls were formulated with minimal ingredients. 1.5% sea salt, 0.5% turbinado sugar, with LV or no LV. Study one evaluated length of mixing time (2.5, 5, 10, 15, 20 minutes) on quality and sensory attributes with 2.5% LV or 0% LV (C). Study two was divided into four treatments, 0% (C), 1.5%, 2.5%, and 3.5% LV, used to evaluate the effects of three levels of LV on quality and sensory attributes. In study one, C treatment increased (P < 0.05) cook yield for beef, however, mixing time had no effect (P > 0.05) on cook yield for beef or turkey. Slices of turkey and beef with LV were darker (L*) and less red (a*). Mixing times increased (P < 0.05) L* for turkey and beef while a* values decreased for beef slices. Twenty minutes of mixing made beef tougher (P < 0.05). Study two found no difference (P > 0.05) in cooking yield between treatments. The pH of the cooked turkey role decreased (P < 0.05) with increasing LV. Slices of beef and turkey L* values were lower (P < 0.05) for LV, and a* values for turkey were lower when compared to C. Most textural analysis for were not different. C turkey slices were less chewy (P < 0.05) than LV 3.5%. Sensory analysis found LV rated higher (P < 0.05) for overall flavor and acceptability for beef. No differences (P > 0.05) were found for overall flavor and acceptability of turkey. Mixing time can affect final product color and the addition of LV can negatively affect beef color when making medium rare roast beef. The addition of LV in reduced salt beef rolls can make the product more flavorful and acceptable to consumers. iii ACKNOWLEDGEMENTS I would first and foremost like to thank my parents, Leonard and Doris VanDeWalle, for everything they have helped me with throughout my life so far. They have always been there when I needed them and they have always been very supportive with the decisions I made throughout college. Everything I have accomplished or will accomplish in the future can be directly attributed to them. I could not have asked for better parents. I want to thank Dr. Dennis Burson for everything he has done for me during my time at UNL. Serving as my major professor, Dr. Burson helped me grow and mature as an individual, and I have learned a lot working with him over the last three years. I really want to thank him for giving me the opportunity to coach the 2008 and 2009 meats judging teams; even though it took him twisting my arm to talk me into it. Coaching the meats judging team helped me find a new passion of teaching and working with college students. I also gained a lot of valuable experience while helping with the many different short courses and gained a great deal of understanding on meat science extension work. I also want to thank Dr. Roger Mandigo for everything I have learned from him during my time here. Dr. Mandigo was very influential and an integral part in getting me interested in graduate school, and opening me up to the idea of continuing my education once I was done with my bachelor’s degree. I learned a lot about processed meats while taking Dr. Mandigo’s ASCI 410 and 817 classes and even more so working with him outside of class and on my project when things weren’t always working right. I also want iv to thank him for all of the “life” talks we had as I believe I learned as much from them as I did from sitting in on classes. Dr. Steve Jones and Dr. Chris Calkins also played a big part in my education and life experiences. I want to thank Dr. Jones for serving as my advisor while I was an undergraduate. He also gave me the opportunity to be a teaching assistant for ASCI 210 multiple times, in which I learned a lot from. I learned a lot from Dr. Calkins while taking his ASCI 310 and 917 classes. The muscle identification was extremely valuable when I was teaching specs to my meat judging teams. Both Dr. Jones and Dr. Calkins were also very influential in my decision to pursue a Master’s degree in Meat Science. I would like to thank Dr. Harshavardhan Thippareddi for serving on my committee. If it wasn’t for Dr. Thippareddi I may have not learned as much as I did about processed turkey. I really want to thank Dr. Susan Cuppett for all the guidance and help she provided when running my taste panels. I also want to thank Robert Weber for allowing me to use his Instron machine, so I could get my research finished up. There are not enough thanks or words to describe how much Sherri Pitchie and Tommi Jones helped me. Sherri was a huge help when I was planning meat judging trip. She always helped me make sure the right paperwork was turned in, a van checked out, and helped me keep my head screwed on to make sure I wouldn’t forget anything. She also helped me level a small forest with all of the copies she made for me over the last three years. I can’t thank Tommi enough for all of the lab work she helped me with. She always made sure I was doing it right, had everything I needed, and would go out of her way to help me with anything. I really can’t thank Sherri and Tommi enough. v I would like to thank Calvin Schrock for hiring me as a student worker during my second semester here. Calvin taught me a lot about slaughter, carcass fabrication, plant sanitation, and keeping HACCP records. He was always willing to help me out with my project, and always there to drink a cup of coffee with and talk about cattle. Many different people helped me with my turkey and beef roll production. I couldn’t have done it without the help of Ben, Bryce, Derek, McKenzie, and any of the student workers in the meat lab who lended a hand when I needed it. vi TABLE OF CONTENTS ACKNOWLEDGEMENTS ..................................................................................................... iii INTRODUCTION .................................................................................................................... 9 REVIEW OF LITERATURE ................................................................................................. 12 I.
