Determining The Effectiveness Of Rosemary Essential Oil On The Shelf Life Of Ground Beef Under Different Lighting Conditions, Jordan Looper
Determining The Effectiveness Of Rosemary Essential Oil On The Shelf Life Of Ground Beef Under Different Lighting Conditions, Jordan Looper
Animal Science Undergraduate Honors Theses
The objective of this study was to determine the effectiveness of rosemary extract on the shelf life of ground beef patties under different retail display conditions. Ground beef patties were produced from an 85% lean and 15% fat blend purchased from a local grocery retailer, finely ground through a 0.953 cm plate and separated into 151.2 g patties (n=64). Patties were randomly assigned into a control group (no antioxidants added) or a 0.20% concentration rosemary extract group. Patties were individually packaged using polyvinyl chloride overwrap. Antioxidant and control patties were randomly assigned into one of two lighting intensity …
Effects Of Retail Case Environment And Led Lighting Temperature On Color And Oxidation Of Previously Frozen Ground Beef Patties, Devin Elaine Whiteside
Effects Of Retail Case Environment And Led Lighting Temperature On Color And Oxidation Of Previously Frozen Ground Beef Patties, Devin Elaine Whiteside
Animal Science Undergraduate Honors Theses
The purpose of this study was to investigate different environments of retail cases and LED lighting temperatures to observe how these conditions affect oxidation of previously frozen ground beef patties. Coarse ground beef (85% lean) was purchased from a commercial beef processor, fine ground through a 10 mm grinder plate, and then formed into 1/3-pound patties with an automatic patty forming machine. Patties were then randomly assigned to four different treatments: open-front display cases with 3000 K lighting (OPEN3000), open-front cases 3500 K lighting (OPEN3500), reach-in door display with 3000 K lighting (CLOSED3000), and reach-in door display at 3500 K …
Effects Of Retail Case Environment And Led Lighting Temperature On Color Of Ground Beef Patties, Mesa Kutz
Effects Of Retail Case Environment And Led Lighting Temperature On Color Of Ground Beef Patties, Mesa Kutz
Animal Science Undergraduate Honors Theses
The objective of this study was to explore different type of retail cases and case environments, primarily lighting, to quantify the impact on shelf life. Coarse ground 80:20 beef from a local retail establishment was acquired between 7 and 10 d from the box date and fine ground through a 9.5 mm grinder plate, and then formed into 150.25 g patties with an automatic patty forming machine. Each patty was then individually packaged in PVC-overwrap packages and randomly assigned to one of the four different treatments: open, multideck cases with 3000 K lighting (OPEN3000),open 3500 K lighting (OPEN3500),enclosed, …
Effects Of 50:50 Proportion Bull:Cow Blend Levels And Incorporation Of Finely Textured Beef On The Color Of Precooked Ground Beef Patties, Colton Allen Althaber
Effects Of 50:50 Proportion Bull:Cow Blend Levels And Incorporation Of Finely Textured Beef On The Color Of Precooked Ground Beef Patties, Colton Allen Althaber
Graduate Theses and Dissertations
Variation in internal cooked color of ground beef is an economic concern for the ground beef market. Persistent pink color in hamburger patties can lead consumers to the perception of an undercooked product. Therefore, the objective of this study was to characterize the effects of bull:cow blend proportions, with or without finely textured beef (FTB), and cookery method on internal color of precooked ground beef patties. Batches (9.1 kg) of 85% lean ground beef were manufactured with 0, 33, 67, or 100% 50:50 bull:cow blend (remainder of lean was 100, 67, 33, or 0% Select-grade knuckles, respectively) mixed with 2 …
Cooking Patties From A Frozen State, Endpoint Temperature, And Post-Cookery Chilling Affect Internal And External Color And Cooking Losses In Ground Beef Patties, Zena Hicks
Animal Science Undergraduate Honors Theses
To determine the effects of cooking state (frozen vs. thawed), endpoint temperature (65.5 vs. 73.9°C), and post-cookery chilling on color of ground beef patties, 85% coarse-ground beef was purchased and ground through a 9.5-mm plate, formed into 115-g patties, and crust frozen before 4 patties were vacuum packaged and stored at -10 °C. Packages were either thawed in a water bath for 2 h prior to cooking or cooked directly from frozen. Within each package, patties were weighed before being cooked to their assigned temperature (65.5 or 73.9oC) and either allowed to cool at room temperature on paper …
Effect Of Feeding Distillers Grains During Different Phases Of Production And Addition Of Postmortem Antioxidants On Shelf Life Of Ground Beef1, B. D. Cleveland, J. O. Buntyn, A. L. Gronli, J. C. Macdonald, University Of Nebraska - Lincoln, G. A. Sullivan
Effect Of Feeding Distillers Grains During Different Phases Of Production And Addition Of Postmortem Antioxidants On Shelf Life Of Ground Beef1, B. D. Cleveland, J. O. Buntyn, A. L. Gronli, J. C. Macdonald, University Of Nebraska - Lincoln, G. A. Sullivan
Department of Animal Science: Faculty Publications
Feeding distillers grains (DGS) to cattle can increase PUFA concentration, increase lipid oxidation, and de- crease color stability of beef. The objective of this study was to evaluate the effects of feeding DGS and the post- mortem addition of antioxidants on the shelf life of ground beef products. Crossbred heifers (n = 64; initial BW = 225 kg) were supplemented with different amounts of modi- fied DGS (MDGS; 0.91 or 2.27 kg daily, DM basis) dur- ing backgrounding and finished on diets containing corn gluten feed or MDGS. Four beef shoulder clods from each dietary group were ground independently. Fatty …
Effects Of Labeling And Consumer Health Trends On Preferred Ground Beef Color Characteristics, Fat Content And Palatability In Simulated Retail Display, Fred W. Pohlman Ii, Fred Pohlman, Nicholas B. Anthony, Famous Yang
Effects Of Labeling And Consumer Health Trends On Preferred Ground Beef Color Characteristics, Fat Content And Palatability In Simulated Retail Display, Fred W. Pohlman Ii, Fred Pohlman, Nicholas B. Anthony, Famous Yang
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
Nutritional concerns have impacted the protein market, decreasing red meat consumption as well as prompting the advent of lean and extra lean ground beef. However, such lean blends of ground beef may suffer in palatability. This study seeks to bridge the gap between perceived health and palatability. Participants were asked to identify the relative importance of characteristics commonly used in purchasing ground beef and select a preferred package of ground beef from labeled and unlabeled sections consisting of 4%, 10%, 20%, and 27% fat content. Instrumental color data and their main drivers were also collected. Participants then completed a blind …
Electrostatic Atomization Of Antimicrobial Treatments On Ground Beef Processing, Instrumental Color, Sensory Color, Taste And Aroma Characteristics, Jorge Abraham Marcos
Electrostatic Atomization Of Antimicrobial Treatments On Ground Beef Processing, Instrumental Color, Sensory Color, Taste And Aroma Characteristics, Jorge Abraham Marcos
Graduate Theses and Dissertations
The general objectives of this research were to evaluate the interaction effects of sixteen different antimicrobial treatments throughout seven days of display on physical, chemical and sensory characteristics of ground beef patties, when compared to an un-treated control. Antimicrobial treatments included: fumaric acid, malic acid, octanoic acid, decanoic acid, sodium propionate, propionic acid solution, potassium lactate/diacetate blend, sodium benzoate, hexanoic acid, pyruvic acid, levulinic acid, lactic acid/ citric acid blend, sodium diacetate, lemon juice and acetic acid. Prior to grinding, beef trimmings (80/20) were electrostatically sprayed with antimicrobial treatment solutions. Ground beef was processed into meat patties and sampled for …
The Color And Consistency Of Steaks And Ground Beef Produced From Mature Bulls, Jace Joseph Hollenbeck
The Color And Consistency Of Steaks And Ground Beef Produced From Mature Bulls, Jace Joseph Hollenbeck
Graduate Theses and Dissertations
Two experiments were conducted to compare the color and cooked attributes of steaks and ground beef produced from mature bulls. Beef from mature bulls was used to test the effects of lactic acid (LA) enhancement solution pH (2.5, 3.0, or 3.5; B25, B30, B35, respectively) on fresh (5 d of display) and cooked color and tenderness of strip loin steaks (Exp. 1) and the effect of high pH trim on precooked ground beef patties (Exp. 2). In experiment 1, mature bull strip steaks were enhanced to 111% with a LA, sodium bicarbonate, and tap water solution, in comparison to USDA …
