Marbling, or intramuscular fat, is an important factor in meat quality. As a key regulator of lipid metabolism, AMP activated protein kinase (AMPK) may be associated with intramuscular fat accumulation and glycogen content in bovine muscle, and muscle fiber type composition in beef cattle. Steers with high intramuscular fat content (High IMF, 5.71 ± 0.36 %, n=5) and low intramuscular fat content (Low IMF, 2.09 ± 0.19 %, n=5) in the longissimus muscle (LM) were selected for analysis. High IMF steers had a reduced AMPK activity, reduced acetyl-CoA carboxylase phosphorylation, decreased glycogen content, and decreased phosphorylation of GSK3 in the longissimus muscle. No noticeable difference in myosin isoform composition was observed between Low and High IMF muscle. This data shows LM lipid and glycogen metabolisms are affected by AMPK activity. High IMF steers also had decreased Warner-Bratzler shear force values leading us to investigate tenderness in these animals. Postmortem proteolysis is an important determinant in beef tenderness. Caspase 3 is a protease that functions in apoptosis and has been shown recently to degrade myofibrillar proteins suggesting it could be involved in postmortem proteolysis. Caspase 3 activity in the LM immediately postmortem was higher for the cattle with increased Warner-Bratzler shear force values. In 5 additional steers we sampled LM over a 10 d period. Western blot analysis LM samples showed only the pro-caspase 3 form and failed to detect the activated enzyme. No significant activation of caspase 3 was detected, only a decreased activity at 72 h and 240 h postmortem was observed. Hence, caspase 3 is not anticipated to be involved in postmortem tenderization of beef. Nutrient restriction (NR) of the dam during gestation can affect muscle development and adipose tissue deposition of offspring. Early to mid-gestation is important for muscle and adipose tissue development in beef cattle. Experiments showed that NR and a low plane of nutrition decreased subcutaneous fat thickness of steers at slaughter and kidney, pelvic and heart fat when nutrient restriction was applied during early to mid-gestation. Additionally, NR and NR plus protein supplementation during early to mid-gestation increased muscle growth when compared to control offspring.

New Aspects of Meat Quality, Second Edition continues to be the leading source of scientific information for what constitutes meat quality for consumers, marketers and producers in the 21st century. The book includes traditional measures of meat quality such as texture, water holding, color, flavor/aroma, safety/microbiology and processing characteristics as well as quality assurance schemes, organic/free range, ethical meat production, and the desirability of genetically modified organisms, amongst others. Users will find comprehensive coverage on developments in our understanding of how muscle structure affects the eating qualities of cooked meat, along with techniques for measuring, predicting and producing meat quality. In addition, the book covers how these new techniques help us minimize variability in eating quality and/or maximize value. The book's final section identifies the current qualities of consumer and public perceptions and what is sustainable, ethical, desirable and healthy in meat production and consumption. Provides the latest research techniques and developments presented by top researchers in the field Covers new aspects of meat quality with the same scientific authority as texts on traditional meat quality value Includes five new chapters that cover the role of proteolysis, meat flavor, meat bi-products, and meat and public health

Extracellular matrix (ECM) is an important constituent of tissues and organs. However, abundant ECM deposition leads to fibrosis. Obesity has become a pandemic around the world, which results in serious diseases, including fibrosis of muscle and adipose tissue. The skeletal muscle and adipose tissue fibrosis is closely correlated with metabolic dysfunction. Additionally, the content and structure of ECM affect the meat tenderness, a main determinant of meat quality. A better understanding of the mechanism in which ECM development and accumulation is necessary for the development of therapeutic for obesity-associated metabolic dysfunctions and meat quality improvement. In this dissertation, three studies are included: (1) AMP-activated protein kinase (AMPK) is a potent inhibitor of fibrosis, which is down-regulated due to obesity. Our data showed that AMPK[alpha]1 deletion in fibrotic/adipogenic progenitors (FAPs) impaired muscle regeneration with increased fibrosis. AMPK[alpha]1 knockout in FAPs enhanced p65 translocation to nuclei, which increased the expression of MMP-9. MMP-9 cleaved latent-TGF-[beta], releasing active TGF-[beta]. Active TGF-[beta] elevated the apoptosis-resistance and fibrotic commitment of FAPs, resulting in fibrosis of regenerated muscle. (2) Lysyl oxidase (LOX), a key enzyme catalyzing collagen cross-linking. AMPK regulates LOX via suppressing TGF-[beta]/SMADs signaling. We found that obesity increased mature nonreducible collagen cross-linking in white adipose tissue (WAT) of mice, which is positively associated with insulin resistance. In addition, enhanced TGF-[beta] due to inactivation of AMPK under the obese condition promoted phosphorylation of SMAD3, the expression of LOX and other fibrogenic genes in white adipose tissue. Moreover, in vivo, AMPK activation suppressed TGF-[beta]1-induced LOX expression and fibrosis. (3) The late gestation is critical for intramuscular fat and connective tissue development, therefore, maternal diet during this stage has an important effect on the offspring beef quality. Besides, breed is another player of meat quality. We tested the effect of breed, Angus versus Wagyu, and dietary protein levels of cows during the late gestation on the offspring beef quality. Our results showed that a mild restriction of protein diet during late gestation had no major effect on beef quality. Furthermore, Wagyu- sired cattle had higher tenderness, marbling score, and less collagen cross-linking products than Angus- sired cattle.

Knowledge of muscle biology is continuing to expand in the animal and food sciences industry, especially the understanding of the mechanisms that control skeletal muscle development, growth, and their impacts on meat production and quality. Applied Muscle Biology and Meat Science provides agriculturalists with state-of-the-art information and a platform to further explore this specialized topic. It also gives novices a comprehensive knowledge base in applied muscle biology and meat science. Many existing problems in meat science and production are due to a lack of understanding of the underlying biological mechanisms of the livestock. Careful to avoid gory processing details, the text focuses on biological changes and the appropriate manage

Food proteomics is one of the most dynamic and fast-developing areas in food science. The goal of this book is to be a reference guide on the principles and the current and future potential applications of proteomics in food science and technology. More specifically, the book will discuss recent developments and the expected trends of the near future in food proteomics. The book will be divided into two parts. The first part (7 chapters) will focus on the basic principles for proteomics, e.g., sample preparation, such as extraction and separation techniques, analytical instrumentation currently in use, and available databases for peptide and protein identification. The second part of the book (26 chapters) will focus on applications in foods. It will deal with quality issues related to post-mortem processes in animal foods and quality traits for all foods in general, as well as the identification of bioactive peptides and proteins, which are very important from the nutritional point of view. Furthermore, consumers are now extremely susceptible to food safety issues, and proteomics can provide reassurance with different safety aspects, such as food authenticity, detection of animal species in the food, and identification of food allergens. All of these issues will be covered in this book. It is also worth noting that both editors are internationally recognized experts in the field of food science, and both have edited numerous food science books and handbooks.
