| For this research 48 male lambs were divided in randomized blocks in a factorial design, having as factors sexual condition (castrated or uncastrated) and time on feed (36 or 78 days). High grain diet was monitored daily to measure the performance of the animal nutrition. The characteristics of the carcass and meat were taken for the fatty acids profile and sensorial analysis. The effect of the factors as sexual condition and time on feed, and the interaction between them, were evaluated by analysis of variance using the GLM procedure of SAS software and the treatment averages were compared by Student's T test. The uncastrated animals presented greater weight gain and dry matter intake, better feed efficiency, and larger loin area. More time on feed... |

| This work was carried out to evaluate the animal performance, carcass characteristics and meat quality of crossbred heifers slaughtered at three different body weights. The heifers were slaughtered with 330 (Light), 360 (Medium) and 400 (Heavy) kg body weight. The final weight, average daily gain and carcass weight were greater for HEA heifers, intermediate for MED heifers and lower for LIG heifers. However, carcass dressing and pH were similar for the three heifers groups. Dripping loss, dissection loss and the muscle, fat and bone percentages on the 6th rib did not alter by slaughter weight. Slaughter weight did not affect the colour, shear force and lipid oxidation of meat. In conclusion, heavy heifers finished in pasture and that were... |

| ABSTRACT Sensory and instrumental analyses evaluated the meat and fat characteristics of feedlot-finished steers fed a diet containing cottonseed. Global impression, texture, meat color, and fat color were assessed. Thirty Nellore bulls with an average age of 30 ± 6 months and initial body weight of 382.7 ± 28.4kg were kept in feedlot stalls and fed the following cottonseed levels: 0; 2.22 %; 4.44 %; 6.66 %; 8.88 %; 11.11 % of the dietary dry matter. The cottonseed used in this experiment had an average free gossypol content of 4.5g/kg of cottonseed. The overall impression of the samples, assessed by the triangle test for difference, did not differ for more than 62 % of the panelists (P>0.01). The shear strength of roasted meat varied from 6.00 to... |

| The effect of dietary conjugated linoleic acid (CLA) in association with two vegetable oil sources on the fatty acids of meat and giblets of broiler chickens was evaluated. Two hundred 21-day-old broiler chickens were distributed in a completely randomized factorial design 2 x 5 (two oil sources, soybean or canola oil; and five levels of CLA, 0.0, 2.5, 5.0, 7.5, and 10.0g/kg). The addition of CLA to the diet resulted in an increase (P<0.05) in CLA deposition in the analyzed tissues. CLA supplementation also reduced (P<0.05) the rate of polyunsaturated to saturated fatty acids in thigh, breast, heart, and gizzard. There was interaction of CLA x oil source (P<0.05). The intake of soybean oil, associated with increasing CLA, resulted in an increase... |

| This article describes the possibility of modifying the composition of fat tissue in broiler chickens fed canola oil, which is high in monounsaturated fatty acids. 128 one-day old broiler chickens, randomly assigned into 4 groups of 32 chicks each, received one of four diets containing 15% oil with different percentages of canola oil (diet 1: 0% canola oil, diet 2: 5% canola oil, diet 3: 10% canola oil and diet 4: 15% canola oil), for 31 days. Each group was divided into 4 subgroups of 8 chicks. The birds were sacrificed at day 45 to obtain tissue samples. The fatty acid composition was measured in meat (legs and breasts), fat (abdominal and subcutaneous) and plasma. An increase in oleic acid (p<0.01) was detected, as well as a decrease in linoleic acid... |

| High levels of microbial contamination, commonly found in animal origin foods and food processing environments, are able to hinder the growth of pathogens in these products and interfere in the results of laboratory analyses for detection of these pathogens. With the aim of verifying the possible interference of the autochthonous microbiota encountered in meat and meat products and processing plants over the presence of Listeria spp., 443 samples, collected from 11 meat retail establishments, were submitted to microbiological analysis to determine the levels of mesophilic aerobes, total coliforms and Escherichia coli and the presence of Listeria spp., according to the methodology proposed by the USDA. The results did not show evident interference of the... |

| Twenty samples of Brazilian meat and meat products were screened by the agar overlay method for bacteriocin-producing lactic acid bacteria, using Lactobacillus sake ATCC 15521 as indicator strain. Based on Gram staining, KOH reaction, catalase test and fermentation of 49 carbohydrates (API 50 CH), three out of seven isolates with confirmed antagonist properties were identified as Lactobacillus curvatus, one as Leuconostoc mesenteroides and one as Leuconostoc sp. Two isolates could not be properly identified using these tests. The inhibitors produced by these strains were sensitive to proteases. Inhibition due to lytic bacteriophages was ruled out, so the isolates were classified as bacteriocin-producing lactic acid bacteria. Four of them presented... |

| Abstract Meat is one of the most perishable foods owing to its nutrient availability, high water activity, and pH around 5.6. These properties are highly conducive for microbial growth. Fresh meat, when exposed to oxygen, is subjected to the action of aerobic psychrotrophic, proteolytic, and lipolytic spoilage microorganisms, such as Pseudomonas spp. The spoilage results in the appearance of slime and off-flavor in food. In order to predict the growth of Pseudomonas fluorescens in fresh meat at different pH values, stored under refrigeration, and temperature abuse, microbial mathematical modeling was applied. The primary Baranyi and Roberts and the modified Gompertz models were fitted to the experimental data to obtain the growth parameters. The Ratkowsky... |

| Salmonella serovars sampled from meat products in Southern Spain (Andalucía) during the period 2002-2007 were analyzed in this study. The serovars most frequently detected (in order) were Typhimurium, Enteritidis, Derby, Anatum and Rissen. Isolates (n = 43) were tested for sensitivity to biocides, including the quaternary ammonium compounds benzalkonium chloride (BC), cetrimide (CT) and hexadecylpyridinium chloride (HDP), and the bisphenols triclosan (TC) and hexachlorophene (CF). The minimum inhibitory concentration (MIC) for the quaternary ammonium compounds was in the range of 25 to 50 mg/L for most isolates, although a few isolates required much higher concentrations, up to 250 mg/L. Bisphenols showed higher inhibitory activity, with a MIC of 2.5 to 25... |

| Abstract Effects of encapsulated (e) sodium tripolyphosphate (STP), sodium pyrophosphate (SPP) and various combinations of encapsulated and un-encapsulated (u) forms of these polyphosphates on lipid oxidation in the cooked ground beef during storage (0, 1, 7 d at 4 0C) were determined. pH, color, cooking loss (CL), thiobarbituric acid reactive substances (TBARS), lipid hydroperoxide (LPO) and soluble orthophosphate (OP) analysis were conducted. Study results indicated that STP increased pH, whereas SPP decreased pH compared to control (p<0.05). SPP was determined as the most effective polyphosphate type to inhibit lipid oxidation (p<0.05). In addition, the use of eSPP significantly reduced OP content compared to uSPP (p<0.05). The lowest TBARS... |

| Abstract This study investigated the presence of generic and verotoxin-producing E. coli as well as enumerated faecal coliforms in 30 beef carcasses in different parts of the slaughter process (after skinning, washing and cooling) at each of three slaughterhouses of the state of Mato Grosso do Sul, Brazil. Among the total number of carcasses examined (n = 90), 39 (43.3%) had generic E. coli. Among the 270 samples analysed, 25 (9.3%) were positive after skinning, 14 (5.2%) were positive after washing and nine (3.3%) were positive after cooling. The majority of isolates of E. coli was collected from samples after skinning, which is considered a critical point of the microbial contamination of carcasses. However, the highest concentration of faecal coliforms... |

| The effect of some precursors on the formation of meat flavour during heating has been investigated. A comparison of the influence of three different precursors, inosine-5'-monophosphate (5'-IMP), cysteine and thiamine, added to the meat systems, showed that formation of certain heterocyclic compounds, like sulfur-containing furans, dithiolanones and thiophenes, was significantly affected by changes in the concentration of precursors. However, aliphatic compounds, such as hydrocarbons, alcohols and ketones were not changed by these additions. Inosine-5'-monophosphate was established to be more effective than cysteine or thiamine in the formation of some "meaty" volatiles, i.e. the furanthiols, when its concentration was increased 10 times in raw meat. |

| Abstract The objective of this research was to evaluate the ability and efficiency of different software tools for the deconvolution of DSC thermograms of protein denaturation in salted beef. The salted samples were obtained by immersing beef pieces in NaCl solutions with concentrations of 20, 50, 100 and 330 g NaCl L-1 of water for 48 hours at 10 °C. The raw beef were used as control samples. Three software tools were considered: (i) Pyris7, (ii) OriginPro v.8, and (iii) Solver tool from MS-Excel. These computer programs were used for estimating the thermal denaturation temperature of myosin, sarcoplasmic proteins, and actin, as well as the value of denaturation enthalpy of these proteins. Based on the results obtained, we concluded that the model... |

| ABSTRACT: This study examined the characteristics of the fatty acids profile in the meat of lambs fed grazing and supplemented with different PUFA sources. Thirty Suffolk lambs were used (37.2±5.4kg BW), grazing on perennial ryegrass (Lolium perenne) (12h d-1) and supplemented (30g kg-1 BW0.75) with ryegrass hay (RGH), or supplements formulated with fishmeal (FHM) or soybean meal (SBM). Lambs were used in a completely randomized design. Results showed an effect on total SFA, with SBM higher than RGH (P=0.033), and SBM and FHM showing higher MUFA content compared with RGH (P=0.001). Total PUFA content was higher for RGH, followed by FHM and with the lowest content for SBM (P=0.001). Concluding that there is a variation in fatty acid content depending on the... |
