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, …
Proteome Basis Of Muscle‐Specific Beef Color Stability, Mahesh Narayanan Nair
Proteome Basis Of Muscle‐Specific Beef Color Stability, Mahesh Narayanan Nair
Theses and Dissertations--Animal and Food Sciences
Fresh beef color is critical to consumers’ purchase decisions, and beef color stability is muscle-specific. Sarcoplasmic proteome plays a critical role in beef color stability. This dissertation focuses on the proteome basis of inter- and intra-muscular variations in beef color.
The first experiment examined the sarcoplasmic proteome of three beef muscles with differential color stability, i.e., longissimus lumborum (LL), psoas major (PM), and semitendinosus (ST), during wet-aging. LL, PM, and ST (n = 8) were subjected to wet-aging for 0, 7, 14, and 21 days. On each aging day, steaks were fabricated, and color and other biochemical attributes were evaluated …

Beef color is a major attribute consumers utilize to make purchasing decisions. It is estimated poor color shelf-life of beef steaks costs the meat industry more than $1 billion annually. Shelf-life color is influenced by a balance of two biochemical processes within steaks: metmyoglobin reducing ability and oxygen consumption. Steaks that exhibit a greater metmyoglobin reducing and a reduced oxygen consumption are typically characterized as more color stable. Characteristics of the muscle fiber or muscle cell are what determine the properties of a steak. Commonly, muscles with more oxidative fibers have an elevated oxygen consumption and reduced metmyoglobin reducing ability. …
Length Of Aging Has Greater Effect Than Lactic Acid Treatment On Color Stability Of Beef Chuck Muscles, G. D. Mccoy, T. A. Houser, T. G. O'Quinn, E. A. Boyle, K. J. Phelps, J. M. Gonzalez

Lactic acid spray washes are widely used as an antimicrobial intervention in the beef industry. Sprays are typically applied to the exterior of carcasses and subprimal cuts to reduce or eliminate potential pathogenic bacteria. While the efficacy of these washes has been proven, other questions remain about their effect on color attributes of meat when applied to subprimal cuts. The objective of this study was to determine the effect of a lactic acid subprimal wash on the color stability of beef chuck rolls.
