Deshidratador solar para productos agrícolas. Colegio de Postgraduados
Hernández Santana, Crescencio Alejandro.
En México un gran porcentaje de la comercialización de frutas y hortalizas se realiza en fresco. Aunque por un lado, es el tipo de producto preferido por muchos consumidores, por otro, existen excedentes que saturan el mercado, bajan los precios alarmantemente y se incrementan las perdidas. No existe la capacidad instalada en infraestructura para conservar estos productos, aún en fresco. Por lo que este trabajo propone el desarrollo de un deshidratador para productos vegetales, que permitirá alargar su vida de anaquel y transformarlo en otro producto de consumo. La culminación de este proyecto, coadyuvará a mejorar la calidad de vida y arraigo social de los pobladores en regiones de origen. Se hicieron pruebas de secado con el nopal (Opuntia ficus indica),...

Drying and rehydration of oyster mushroom BABT
Apati,Giannini Pasiznick; Furlan,Sandra Aparecida; Laurindo,João Borges.
Dehydration and rehydration processes of Pleurotus ostreatus fruiting bodies were investigated in this work. Mushroom samples were dehydrated at 40, 50 and 60 ºC, using drying air with relative humidity of 75 %. The rehydration was investigated at different temperatures of immersion water (25, 55 and 85 ºC) and different immersion times (30, 75 and 120 minutes). The best rehydration occurred for the samples dried at 40 ºC. The rehydration could be done in water at room temperature, during 30 minutes. Water sorption isotherms of samples were determined at 30, 40 and 50 ºC. Both GAB and BET models satisfactorily represented the experimental data of moisture sorption of dried mushrooms.

Drying kinetics of atemoya pulp AGRIAMBI
Galdino,Plúvia O.; Figueirêdo,Rossana M. F. de; Queiroz,Alexandre J. de M.; Galdino,Pablícia O..
ABSTRACT This study was conducted in order to obtain drying curves of whole atemoya pulp through the foam-mat drying method. The suspension was prepared with whole atemoya pulp mixed with 2% of Emustab® and 2% of Super Liga Neutra® with mixing time of 20 min, and dried in a forced-air oven at different temperatures (60; 70 and 80 °C) and thicknesses of the foam layer (0.5, 1.0 and 1.5 cm). The drying rate curves were plotted against the water content ratio and the semi-theoretical models of Henderson & Pabis, Page and Midilli were used. All tested models showed coefficient of determination (R2) above 0.993, and the Midilli model showed the best fit for all conditions. Drying curves were affected by temperature and layer thickness.

Drying kinetics of bananas by natural convection: Influence of temperature, shape, blanching and cultivar Ciência e Agrotecnologia
Borges,Soraia Vilela; Mancini,Maurício C.; Corrêa,Jefferson Luiz Gomes; Leite,Julia Benedito.
The influence of variables as temperature, solid shape, temperature, branching and cultivar on drying of bananas were studied. Bananas from cv. Prata and D'água, on disk and cylindrical shape, blanched or not, were dehydrated in a tray dryer in natural convection at 40 and 70ºC. Drying behavior was analyzed by using a mathematical model. The exponential model showed good agreement to experimental data (r² 0.93 - 0.99 and standard error: 0.01- 0.05). Temperature presented positive influence on drying rate in all the tested conditions. With respect to the sample shape, the disk shape carried out to significantly higher drying rates only for D'água cultivar without blanching. Blanching was significantly influent, with positive influence, on drying rate of...

EFFECT OF DRYING KINETICS ON COLOR OF “DEDO DE MOÇA” CHILI PEPPERS (Capsicum baccatum) REA
Andrade,Ednilton T. de; Figueira,Vitor G.; Teixeira,Luciana P.; Martinazzo,Ana Paula; Araujo,Kátia G. de L..
ABSTRACT This study aimed to assess the drying kinetics of red and yellow chili peppers, “dedo-de-moça” variety, at different temperatures (35, 45, 55, and 70 °C) and model this phenomenon mathematically. We also evaluated the effect of these drying air temperatures on pepper fruit color. Pepper fruits were dried in a forced-air circulation dryer. Ten mathematical models were fitted to the experimental data by nonlinear regression analysis. After drying, pepper samples were analyzed for the following colorimetric parameters: lightness (L*), chroma or saturation (c), and hue angle (h), in order to determine the influence of drying air temperature on fruit coloration. Our findings showed that the higher the air temperature, the faster the drying process....

Effect of injection of L-NAME on drinking response BJMBR
Saad,W.A.; Camargo,L.A.A.; Saad,R.; Pereira,A.F.; Simões,S..
The drinking behavior responses to centrally administered NG-nitro-L-arginine methyl ester (L-NAME; 10, 20 or 40 µg/µl), an inhibitor of nitric oxide synthase, were studied in satiated rats, with cannulae stereotaxically implanted into the lateral ventricle (LV) and subfornical organ (SFO). Water intake increased in all animals after angiotensin II (ANG II) injection into the LV, with values of 14.2 ± 1.4 ml/h. After injection of L-NAME at doses of 10, 20 or 40 µg/µl into the SFO before injection of ANG II (12 ng/µl) into the LV, water intake decreased progressively and reached basal levels after treatment with 0.15 M NaCl and with the highest dose of L-NAME (i.e., 40 µg). The water intake obtained after 40 µg/µl L-NAME was 0.8 ± 0.01 ml/h. Also, the...

Effects of central imidazolinergic and alpha2-adrenergic activation on water intake BJMBR
Sugawara,A.M.; Miguel,T.T.; Pereira,D.T.B.; Menani,J.V.; De Luca Jr.,L.A..
Non-adrenergic ligands that bind to imidazoline receptors (I-R), a selective ligand that binds to alpha2-adrenoceptors (alpha2-AR) and mixed ligands that bind to both receptors were tested for their action on water intake behavior of 24-h water-deprived rats. All drugs were injected into the third cerebral ventricle. Except for agmatine (80 nmol), mixed ligands binding to I-R/alpha2-AR such as guanabenz (40 nmol) and UK 14304 (20 nmol) inhibited water intake by 65% and up to 95%, respectively. The selective non-imidazoline alpha2-AR agonist, alpha-methylnoradrenaline, produced inhibition of water intake similar to that obtained with guanabenz, but at higher doses (80 nmol). The non-adrenergic I-R ligands histamine (160 nmol, mixed histaminergic and...

Enteral fluid therapy in neonatal calves and features of commercially available electrolyte solutions in Brazil Ciência Rural
Bregadioli,Gabriela de Castro; Pereira,Priscilla Fajardo Valente; Flaiban,Karina Keller Marques da Costa; Ribeiro Filho,José Dantas; Lisbôa,Júlio Augusto Naylor.
ABSTRACT: According to the World Health Organization, the development of orally replacement fluids and electrolytes was one of the most significant advances of the twentieth century, markedly reducing mortality from diarrheal children. In veterinary medicine, oral electrolyte solutions (OES) are routinely used to treat diarrheic neonatal calves in order to correct water, electrolyte and acid base imbalances. In North America, the use of OES is routine and there are at least 20 commercial alternatives. Use of OES has increased in recent years in Brazil, but just five commercial products are currently available. The OES should contain, in suitable concentrations, electrolytes, glucose and an alkalizing agent to ensure its therapeutic efficacy. This review...

Episodes of water deprivation enhance daily hypertonic NaCl intake in rats BJMBR
Pereira,D.T.B.; David,R.B.; Menani,J.V.; De Luca Jr.,L.A..
Water and 1.8% NaCl intake was recorded daily in adult male rats (N = 6) submitted to four water deprivations plus four sodium appetite tests, each at the end of each 7-day interval, or in controls (non-deprived, N = 6). Water deprivation was achieved by removing water and 1.8% NaCl for 24 h. Water was then offered for 2 h. At the end of this period, 1.8% NaCl was also offered in addition to water (sodium appetite test). Average daily 1.8% NaCl intake was enhanced from 5.2 ± 1.0 to 15.7 ± 2.5 ml from the first to the fifth week in the experimental group and was unchanged in the control group. Daily water intake was not altered in either group. Thus, repeated episodes of water deprivation enhance daily NaCl intake.

Fluid therapy in large animais - Part II: amount and administration routes MV&Z
Dearo, Antônio Cézar de Oliveira; Reichmann, Peter.
The amount, administration routes and fluid flow rates are as important as the indications of fluid therapy and which fluid to use. Considering that fluid therapy is often maintained for long periods in many clinical situations, the use of intravenous catheters and large animal IV administration sets reduce the need for continuous supervision.

Gastric emptying of liquids in rats dehydrated by water deprivation BJMBR
Baracat,E.C.E.; Collares,E.F..
The gastric emptying of liquids was investigated in male Wistar rats (8 to 10 weeks old, 210-300 g) dehydrated by water deprivation. In this model of dehydration, weight loss, hematocrit and plasma density were significantly higher in the dehydrated animals than in the control groups after 48 and 72 h of water deprivation (P<0.05). Three test meals (saline (N = 10), water (N = 10) and a WHO rehydrating solution containing in one liter 90 mEq sodium, 20 mEq potassium, 80 mEq chloride and 30 mEq citrate (N = 10)) were used to study gastric emptying following water deprivation for 24, 48 and 72 h. After 72 h, gastric emptying of the water (39.4% retention) and rehydrating solution (49.2% retention) test meals was significantly retarded compared to the...

Heart rate and body weight alterations in juvenile specimens of the tropical land snail Megalobulimus sanctipauli during dormancy BJMBR
Rizzatti,A.C.S.; Romero,S.M.B..
The time course of heart rate and body weight alterations during the natural period of dormancy were determined in active feeding and dormant juvenile specimens of Megalobulimus sanctipauli. In both groups, heart rate markedly decreased during the first 40 days of dormancy, tending to stabilize thereafter. This time period coincided with the decrease in environmental temperature during autumn-winter. At the end of the dormancy period, surviving active feeding and dormant snails showed a significant decrease in heart rate which, however, was significantly greater in the latter group. Total body weight decreased concomitantly with heart rate in dormant snails but remained constant in active feeding snails. Body hydration induced significant increases in...
