| Abstract The aim of this work was to study the myofibril proteins and collagen fraction changes in broiler chickens PSE (pale, soft, exudative) meat during ageing and their relationship to meat quality. The results presented an increase of myofibril proteins and collagen solubility promoted by the enhanced proteases activities during storage. Ultramicroscopically, the PSE meat samples revealed intracellularly a sarcomere super contraction and lacunas within the A and I bands while Z-lines appeared very dense and fragmented in comparison to normal samples. This observation was noticed already at 4h storage while extracellularly collagen fibrils decreased visually within the endomysium only after 24h of conditioning. These results influenced the quality as... |

| The objective of this work was to investigate the effect of road transportation conditions on the occurrence of broiler PSE-(Pale, Soft, Exudative) and DFD-like (Dark, Firm, Dry) meats in the Brazilian commercial slaughterhouse plant. Samples of Pectoralis major m from 47-day-old broilers of commercial lineage were analyzed. The results indicated that water-bathing birds just before journey over 3.0km promoted the occurrence of 46.0% of PSE and 4.0% of DFD-like meat, while birds under non-water bathing conditions presented 14.7 and 2.0%, respectively. For a distance of 68.0km, the occurrences of PSE-and DFD-like meat were 44.0 and 0.0% under water bathing conditions, and 52.0 and 0.0% without water bathing, respectively. Water bathing at the farm was a... |

| The objective of this work was to analyze changes in the isoflavone profile, determined by high performance liquid chromatography, at different processing stages and after refrigeration of tempeh. For tempeh production, clean soybean grains from cultivars BR 36 (low isoflavone content) and IAS 5 (high) were dehulled, and the separated cotyledons were hydrated and then cooked in boiling water for 30 min. Spores of the fungus Rhizopus microsporus var. oligosporus were inoculated in the cooked and cooled cotyledons, and incubated at 32ºC for 6, 12, 18, and 24 hours in perforated polypropylene bags, for fermentation. The resulting tempeh was stored at 4ºC for 6, 12, 18, and 24 hours. After 24-hour fermentation, isoflavone glucosides were 50% reduced, and the... |

| A soja (Glycine max (L.) Merrill) é uma das leguminosas mais estudadas, em virtude de sua intensa utilização como fonte de óleo comestível e proteína para alimentação humana e animal. A presença de inibidores de tripsina na soja limita sua utilização, tornando necessário o processamento térmico para melhorar sua qualidade nutricional. Entretanto, o processamento térmico excessivo ou inadequado pode reduzir a qualidade da proteína. Neste trabalho, foram utilizados cultivares de soja BR-36, com atividade normal de inibidores de tripsina, e cultivares BRM 95-5297 e BRM 95-5262, com baixas atividades de inibidores de tripsina. As farinhas com 10 e 16% de umidade foram aquecidas em banho a 95°C, com cinco intervalos (15, 25, 50, 75 e 100 minutos) de retenção;... |

| The objective of this work was to study the effect of blue light diffuser on the broiler stress control by measuring the occurrence of PSE meat just before slaughtering. Birds were divided into the following two groups before slaughter at the point of being hung on shackles: broiler group under low intensity blue light ambience (475, 17-20 lx) and control group under white light (550-650nm, 321-332 lx). Birds' stressful conditions were measured by the occurrence of PSE meat. Breast fillets were classified as PSE meat based on pH (<5.8) and lightness (L*> 53.0). The fillet samples in the control group had the following characteristics: pHu=5.77, L* = 54.26 and b*= 6.27. The fillet samples from birds under blue light ambience had the following... |

| Abstract: The objective of this work was to evaluate the effect of the processing conditions of soybean tempeh on the contents of β-glycoside isoflavones and on their bioconversion into aglycones. Different times of soaking (6, 12, and 18 hours), cooking (15, 30, and 45 minutes), and fermentation (18, 24, and 30 hours) with Rhizopus oligosporus at 37°C were evaluated for tempeh preparation. Grains from the cultivar 'BRS 267' were used, and the experiment was carried out according to a central composite design (23). The response functions comprised the contents of genistin, malonyldaidzin, malonylgenistin, daidzein, and genistein, quantified by ultraperformance liquid chromatography (UPLC). Soaking, cooking, and fermentation times change the content,... |

| Este trabalho foi conduzido para avaliar o efeito da germinação sobre os constituintes antinutricionais da soja, ácido fítico, P total e inibidores de tripsina, que interferem na utilização de proteínas e outras substâncias. A diminuição no aproveitamento de nutrientes resulta em inibição de crescimento, hipoglicemia ou danos a tecidos animais. Para os ensaios foram utilizadas as cultivares de soja (Glycine max (L.) Merrill ) BR-13 e Paraná. As sementes foram incubadas em câmara de germinação a 25°C e 100% de umidade, de 0 a 72 horas, com coleta de amostras em intervalos eqüidistantes de seis horas. A cultivar Paraná apresentou teores superiores de ácido fítico, P total e inibidores de tripsina, em relação à cultivar BR-13. As análises de variância e... |

| Abstract: The objective of this work was to evaluate the effects of the germination conditions of 'BRS 216' soybean (Glycine max) on the length, yield, and isoflavone contents of sprouts. A 23 factorial arrangement was used to evaluate the variables soaking time, irrigation frequency, and germination time. Sprouts that showed better length and yield and higher isoflavone contents were evaluated for their chemical composition and vitamin C content. Soaking and germination time of soybean showed a positive and significant linear effect on sprout length. However, only germination time showed a significant positive linear effect on yield, and a significant negative linear effect on the content of malonylglycosides, aglycones, and total isoflavones. Soybean... |

| The aim of this work was to evaluate pH values fall rate in chicken breast meat under commercial refrigeration processing conditions and the development of PSE (pale, soft, exudative) meat. Broiler breast samples from the Cobb breed, both genders, at 47 days of age (n = 100) were taken from refrigerated carcasses (RS) immersed in water and ice in a tank chilled at 0°C (±2). pH and temperature (T) values were recorded at several periods throughout refrigeration in comparison to samples left at room T as control (CS). The ultimate pH (pHu) value of 5.86 for RS carcasses were only reached at 11°C after 8.35 h post mortem (PM) while, for CS samples, pHu value was 5.94 at 22°C after 4.08 h PM. Thus, under commercial refrigeration conditions, the glycolysis rate... |

| The aim of this work was to study the influence of lipid oxidation on broiler breast meat (Pectoralis major m) color abnormalities. There were 27.0 % more lipid oxidation in PSE in relation to normal meat and 41.0 % more in relation to DFD-like meat (p<0.05). The fatty acid profile was also significantly different since the arachidonic acid (AA) fraction increased 38.6 and 70.5 % in PSE meat comparing to normal and DFD-like meats, respectively. The ratio PUFA/SFA changed in these three types of meat: 0.736, 0.713 and 0.694 for PSE, normal and DFD-like meat respectively, reflecting the highest production of polyunsaturated fatty acids in the PSE meat samples. Results indicated that phospholipase A2 enzyme activities played a relevant role towards the... |

| Abstract: The objective of this work was to evaluate the effects of zinc concentration in acidified brine and of pasteurization time on the zinc content, color, and physicochemical and microbiological characteristics of canned vegetable-type soybean (Glycine max). The 22 central composite rotational design (CCRD) was used, with zinc concentration in the acidified brine and duration of pasteurization as variables, resulting in 12 assays. A canning formulation was developed and compared with canned-vegetable type soybean without zinc and with fresh-vegetable type soybean, with microbiological evaluation. Zinc addition within the limits defined by Food and Drug Administration (≤75 ppm) does not affect the physicochemical and microbiological characteristics of... |
