The food of animal origin is often involved in salmonellosis outbreaks; contamination with Salmonella can begin on breeding sites during meat processing and the distribution channels. A total of 2,592 samples of chicken, pork and beef ground meat (864 samples of each type) acquired in travelling markets and supermarkets located in the Iztapalapa delegation of Mexico City were analyzed. (Salmone...

A study was conducted to investigate the effect of oregano essential oil on the oxidative stability and color of raw and cooked chicken breast meats. Five treatments, including (1) control (none added); (2) 100 ppm oregano essential oil; (3) 300 ppm oregano essential oil; (4) 400 ppm oregano essential oil; and (5) 5 ppm butylated hydroxyanisole (BHA), were prepared with ground boneless, skinles...

Amino acid, Fatty acid, Meat, Freezing. Due to the effect of cold treatment on the amino acid profile of meat has not sufficiently studied. This study aimed to study the effect of freezing temperature and duration of frozen storage on amino acid profile and fatty acid pattern in imported beef meat, local beef meat, chicken breast and Nile tilapia fish. The effect of freezing on lipid and protei...

Soluble proteins, myofibrillar proteins, collagen, texture, and cook loss were evaluated at different meat temperatures by heating ground and formed chicken breast meat in brass containers in a water bath to temperatures of 40, 50, 60, 70, or 80 C. The soluble proteins decreased by approximately 90% as meat temperature increased from 23 to 80 C. The myofibrillar protein subunits of molecular we...

A lower price on poultry meat, compared with other meats (beef, pork etc.), affects the increasing demand for poultry meat. The productivity and production cost of broiler chickens are directly related to the amount of feed fed, the proportion of crude protein in the feed, and the biological value and price of the feed. The EU produces only 30% of the protein crops used for feed; thus, the larg...

The International Agency for Research on Cancer has classified red meat as "probably carcinogenic to humans" (Group 2A). In mechanistic studies exploring the link between intake of red meat and CRC, heme iron, the pigment of red meat, is proposed to play a central role as a catalyzer of luminal lipid peroxidation and cytotoxicity. In the present work, the novel A/J Min/+ mouse was used to inves...

BACKGROUND There is a need for a reliable and accurate method for quantification of each of the seven individual vitamin B(6) compounds including pyridoxine-β-glucoside in foods. OBJECTIVE To determine pyridoxal (PL), pyridoxamine (PM), pyridoxine (PN), pyridoxal 5'-phosphate (PLP), pyridoxamine 5'-phosphate (PMP), pyridoxine 5'-phosphate (PNP), and pyridoxine-β-glucoside (PNG) in foods. DE...

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...

In this paper, authors summarise studies refferering to enrichment of breast and thigh muscles with carnosine that has an important function in physiological processes. Research shown improves quality chicken meat. By adding amino acids β-alanine L-histidine chickens’ feed, synthesizes skeletal muscles, brain, heart muscle olfactory receptor cells. It been determined the content depends on type...

the main objective of this study was to evaluate the response of consumers to changes in income and prices of chicken meat in the short run and long run. in order to achieve this goal, vector auto regression (var) and vector error correction model (vecm) have been applied to data since 1974 to 2007. impulse response function (irf) calculation indicated that past and present consumption of chick...
