Kato,Talita; Barbosa,Claudia Freitas; Ida,Elza Iouko; Soares,Adriana Lourenço; Shimokomaki,Massami; Pedrao,Mayka Reghiany.
The objective of this work was to investigate the relationship between poultry PSE meat and water loss of frozen chicken carcass in two experiments. The first experiment was carried out in commercial abattoir. Poultry carcass were classified as PSE meat (n=59) (pH <5.8) and control samples (n=55) (pH &gt;5.8). Water absorption and drip test were performed according to the Brazilian legislation methodologies. The second experiment was carried out with commercial whole five brands frozen carcasses purchased from the local supermarkets (n=30) and analyzed for pH, water holding capacity (WHC) and drip test. PSE poultry meats absorbed 3.59% of water during the processing similar to the control samples; however, released 0.38% more water during thawing of...

Determination of Moisture Levels, Protein and Water Absorption of Chicken Giblets Rev. Bras. Ciênc. Avic.
Scaratti,D; Geremias,R; Franchin,PR; Scaratti,G.
Abstract This study aimed at evaluating the levels of moisture, protein, water to protein ratio, and water absorption during chilling of chicken giblets (heart, liver, and gizzard) to set legal limits of water absorption during this process. The survey was conducted in the southern Brazil, the largest broiler-producing region of this country. Giblets (heart, liver, and gizzard) were collected fresh from the processing line after evisceration and at the exit of the chiller after the immersion process from two processing plants. One of the plants (PP1) processes small chickens (1,100g live weight) and PP2 processes chickens with 2,800g live weight. In total, 448 samples were collected. Laboratory tests were performed in duplicate for each parameter measured....

Effect of drying temperature on quality of β-glucan in white oat grains Ciênc. Tecnol. Aliment.
Oliveira,Leandro da Conceição; Oliveira,Maurício; Meneghetti,Volnei Luiz; Mazzutti,Simone; Colla,Luciane Maria; Elias,Moacir Cardoso; Gutkoski,Luiz Carlos.
Oats have received attention because of their nutritional characteristics, especially their high-quality content of β-glucan. The drying process reduces water content; therefore they can be preserved for long periods. However, high-temperature drying process may affect the physical, chemical, and functional properties of the grains. The objective of this study was to evaluate the effect of different drying temperatures on β-glucan quality in oat grains. Grains of oats (Avena sativa, L.), cultivar Albasul, harvested at harvest moisture content of 23% were submitted to stationary drying at air temperatures of 25, 50, 75, and 100 ºC until they reached 13% moisture content. The β-glucan content was determined in samples of oat grains and extraction was...

Impact of dry- and hydro-thermal treatments on swelling power, water absorption and water solubility on red-rice flours CIGR Journal
Pratama, Filli.
The impact of dry- and hydro-thermal treatments on swelling power (SP), water absorption (WA) and water solubility (WS) of red-rice flour (RRF) were investigated. The dry-thermal treatment was conducted at RRF’s moisture content (mc) of 10%, and the hydro-thermal treatment was performed at the mc of 25%. There were two heating methods applied on RRF: oven (80oC) and autoclave (121oC) heating. The exposure duration was 8, 10 and 12 hours in an oven-heating; 15 and 30 minutes in an autoclave-heating. Results showed that exposure durations, moisture content and theirs interaction had significant effect on SP and WS of RRF for the autoclave-heating. WA and WS increased with longer exposure duration to heat, and at a higher heating temperature. WA of RRF...

Instant blend from cassava derivatives produced by extrusion Ciência Rural
Trombini,Fernanda Rossi Moretti; Mischan,Martha Maria; Leonel,Magali.
ABSTRACT: The current research aimed to evaluate the effects of extrusion parameters on the physical characteristics of extruded blends of cassava leaf flour and starch. A factorial central composite design with four independent variables and the response surface methodology were used to evaluate the results of color parameters (L*, a*, b*), water absorption index, water solubility index and paste properties, according to the variations in the leaf flour percentage (1.5 to 7.5%), extrusion temperature (60 to 100ºC), screw speed (175 to 231rpm) and moisture (20 to 30%). Extrusion conditions affect color, water absorption and water solubility indexes and paste properties of blends. The intermediate tested conditions of variable parameters lead to obtain...

Kinetics study and modelling of sorghum grain hydration Rev. Ciênc. Agron.
Silva,Danielli Alessandra Reino Olegário da; Jorge,Luiz Mário de Matos; Jorge,Regina Maria Matos.
ABSTRACT Sorghum grains were soaking to evaluate the effects of time and temperature on moisture and process modelling was maked with different mathematical equations. Then, sorghum BRS 310 and BRS 655 were hydrated at 30 °C, 40 °C, 50 °C and 60 °C, for 12 hours. The hydration kinetics modelling with empirical equations of Peleg and Page and phenomenological equations of Diffusion and Omoto-Jorge were considerad. The time and temperature affected significantly the hydration kinetics of grain sorghum. The Peleg and Diffusion models showed the best fitting for soaking and, therefore, these models were used to create generalized models. The effective diffusion coefficient of water during the grain sorghum hydration ranged from 2.02x10-11 to 6.34x10-11 m2.s-1...

Limit between stages I and II of a seed imbibition curve Scientia Agricola
Pinho,Sheila Zambello de; Carvalho,Lídia Raquel de; Delachiave,Maria Elena Aparecida.
A knowledge of the imbibition stages shown by different species, is essential in research projects aiming at improvement of seed quality by treatments such as osmotic conditioning, initial wetting, and the use of bioregulators. The objective of this study was to establish a methodology to determine the limit between the first and second stages of the process, considering the model W = f(t) - (a - w0)exp(-kt), using statistical tests. This limit was determined using an asymptotic distribution of an estimator function. The data point beyond which the difference (W*) is no longer significant was determined using Student's T statistics. The model is <img border=0 id="_x0000_i1026" src="../../../img/revistas/sa/v61n1/a03img01.gif" align=absmiddle > or =...

Modelling mass transfer during water absorption of closed mouth pistachios CIGR Journal
Kouchakzadeh, Ahmad; Tajri, Behnam.
This study was undertaken to analyze the kinetics of water absorption and to derive an equation for the rate at which water is absorbed by closed mouth pistachios.  We used Kaleh_ghoochi, the major variety of Iranian pistachios.  The water-absorption rate equation of closed mouth pistachios between 5°Cand 25°Cwas presumed based on the Peleg equation.  The Peleg coefficients k1 and k2 were negligible changed with water temperature depending on the product and can be useful in estimating approximate immersing time and temperature for splitting mouth of pistachios.

Modelling the non Fickian water absorption in polyamide 6 ArchiMer
Arhant, Mael; Le Gac, Pierre-yves; Le Gall, Maelenn; Burtin, Christian; Briancon, Christophe; Davies, Peter.
This paper investigates the water absorption of polyamide 6. The high amount of absorbed water in the polymer and the large resulting decrease in the glass transition temperature (Tg) leads to a non Fickian water diffusion when samples are immersed, which is a significant difficulty when trying to model the water profile in thick specimens. The aim of this study is to be able to model this particular behaviour based on physical considerations. First, it is shown that the non Fickian water diffusion is caused by an increase in the diffusivity during water absorption. Two cases are then identified; one below Tg where the diffusivity is described using an Arrhenius law and one above Tg based on the free volume theory. Then, these two laws are implemented in a...

Physical-mechanical properties of multinutrient blocks with different binders for goats and sheep intake AGRIAMBI
Furtado,Dermeval A.; Castro,Thiago B. de S.; Lopes Neto,Jose P.; Constantino,Rodrigo A.; Cunha,Maria das G. G.; Nascimento,José W. B. do.
ABSTRACT Feed supplementation with multinutrient blocks (MB) for sheep and goats can be a viable alternative in the Brazilian semiarid region, and it is necessary to set an ideal hardness to obtain maximum feed efficiency. Therefore, this study aimed to evaluate the manufacture of MB using five binders: Portland cement, lime, kaolin, Portland cement + kaolin and lime + bentonite, at two percentages (7.5 and 10%) and two healing times (72 and 96 h). The experimental design was completely randomized in a 5 x 2 x 2 factorial scheme (binders, percentages and healing times, respectively), with five repetitions. Using lime in the MBs led to greater resistance in the specimens (208.53 kPa), as well as the greater percentage of binders (10%), ensuring higher...

MANDARINO, J. M. G.; KRZYZANOWSKI, F. C.; FRANÇA-NETO, J. B.; HENNING, A. A.; VAL, W.M.C..
Determinou-se os teores percentuais de óleo e proteína nas sementes de doze genótipos de soja de ciclos precoce e semi-precoce, e de dez genótipos de ciclo médio, oriundas dos ensaios regionais de avaliação no Estado do Paraná, nas regiões de Londrina, Campo Mourão e Palotina. Observou-se que não ocorreram diferenças significativas para proteína nos genótipos precoces e semi-precoces nas regiões de Londrina e Campo Mourão, com teores médios de 42,04% e 39,81%, respectivamente. Na região de Palotina, provavelmente devido a temperaturas mais elevadas o teor percentual médio de proteína encontrado nas sementes foi maior (43,23%), sendo o menor percentual para a cultivar BR 16 (39,81%) e o maior para a cultivar EMBRAPA 1 (44,84%). Nos genótipos de ciclo médio,...

Water absorption process capability analysis by chicken carcasses during precooling Ciênc. Tecnol. Aliment.
LORENZETTI,Elidiane; PUTON,Bruna Maria Saorin; STEFFENS,Juliana; JUNGES,Alexander; PAROUL,Natalia; BACKES,Geciane Toniazzo; VALDUGA,Eunice; CANSIAN,Rogério Luis.
Abstract Cooling of carcasses using water immersion is the most used process in the poultry industry. In this stage, besides the reduction of temperature, water absorption in the carcasses occurs and, consequently, in the chicken cuts, which are monitored by the companies and supervised by the Ministry of Agriculture, Livestock, and Supply of Brazil, which establishes water absorption limits. The objective of this work was to evaluate the process capacity analysis tool to analyze the water absorption capacity by chicken carcasses during precooling, based on the absorption indexes obtained on an industrial scale, by the analysis of 720 carcasses. After structural alterations, aiming at greater bubble control and shorter residence time of the chicken...

Water diffusivity in PA66: Experimental characterization and modeling based on free volume theory ArchiMer
Broudin, M.; Le Gac, Pierre-yves; Le Saux, V.; Champy, C.; Robert, G.; Charrier, P.; Marco, Y..
Diffusion of water in polyamide 6.6 has been characterized for a wide range of temperatures (from 25 to 80 °C) and various humidities using dynamic vapor sorption machine. The decrease in glass transition temperature (Tg) has also been measured using DMA tests. As usually observed, PA66 absorbs a large amount of water (up to 5% at 90%RH) with a Fickian behavior with a diffusion coefficient that depends on water activity for all temperatures. Moreover, it appears that the diffusion coefficient for tests performed below Tg is almost independent of the water activity whereas a strong dependency is observed above Tg. This behavior is to be compared to a large decrease of Tg with the absorption of water. The increase of the water diffusion can therefore be...
