background toxoplasma gondii is an obligate, intracellular parasite, which is widely spread in the world. the parasite is able to infect all warm-blooded hosts including human.the infection occures via consumption of food or water containing oocytes, eatingundercooked meats containing tissue cysts, and placenta. undercooked meat consumption is one of the most important ways of toxoplasma transm...

by Ting Jiang, M.S. Washington State University December 2008 Chair: Mark L. Nelson Fatty acids in meat have obtained a lot of attention from both scientists and consumers because fatty acids are demonstrated to be closely related with human health and meat is an important food source, especially, for developed countries. Beef has been the most consumed red meat in the US and the argument exist...

OBJECTIVE The objective of this research was to evaluate the physico-chemical, microbiological and sensorial qualities of restructured steaks processed from beef trimmings (grade I and II) and frozen beef (fresh beef as control and frozen beef). METHODS Beef trimmings from commercial butcher were collected, designated into 4 treatments differing in beef trimmings grade and freezing, processed...

BACKGROUND Red meat allergy presents a novel form of food allergy with severe delayed allergic reactions where IgE antibodies are directed against the carbohydrate α-Gal epitope. Food preparation and processing can influence the allergenicity of proteins. The aim of this study was to characterize the proteomic profile of different beef preparations and to investigate their α-Gal reactivity and ...

Meat is a significant source of high-quality nutrients, which are very important in the diet. Among meat products, one of the most prized is bovine meat, of which male beef has been designated to be of a higher quality. However, because of its similarity with female beef, deliberate or unintentional substitutions can occur. To avoid this, methodology based on the fast real-time polymerase chain...

enterohemorrhagic escherichia coli (ehec) of the o157:h7 serotype is a worldwide zoonotic pathogen responsible for the majority of severe cases of human ehec disease. the aim of the present study was to investigate the prevalence of e. coli o157: h7/nm in raw meat samples from two provinces of iran. during a period from march 2010 to march 2011. two hundred and ninety five raw meat samples were...

the aim of this study was evaluation of phytochemical components, antioxidant activity, and antibacterial effects of basil (ocimum basilicum l.) essential oil (beo) in vitro. the lipid oxidation of the meat and antibacterial effects of beo were also evaluated in beef burger product. in this empirical study, essential oil of the basil was isolated by hydrodistillation. then, beo was analyzed by ...

The objective of this research was to determine the difference in myofibrillar fragmentation of camel meat and beef during postmortem aging. Semitendinosus muscle was excised at slaughter and muscle pH was measured at 6, 12, 24, 48, and 72h postmortem. Myofibril fragmentation index was measured on 1, 3, 5, and 7 days postmortem. Also, myofibrils isolated from semitendinosus muscles of camel and...

The aim of the present study was to analyze the fatty acid composition and cholesterol content of the beef and chicken meat most often consumed by a population of type 2 diabetic patients in Southern Brazil: for beef, semimembranosus and biceps femoris; and for chicken, drumstick and thigh. The moisture content (gravimetrically), protein content (Kjeldahl procedure), cholesterol content (HPLC o...

Beef loins with 3 different aging times after slaughter were ground, added with none, 0.1% ascorbic acid, 0.01% sesamol+0.01% a-tocopherol, or 0.1% ascorbic acid+0.01% sesamol+0.01% tocopherol. The meats were packaged in oxygen-permeable bags, irradiated at 2.5 kGy, and color, oxidation–reduction potential (ORP), lipid oxidation and volatile profiles were determined. Irradiation decreased the r...
