| La partie sud ouest de la baie de Tunis subit les apports de l’oued Méliane qui est le deuxième oued pérenne de la Tunisie. Afin de cerner le profil physicochimique de cette partie de la baie, des prélèvements mensuels ont été effectués au niveau de 22 stations dont 19 dans la partie Sud Ouest de la baie de Tunis et 3 en aval de l’oued Méliane pendant les deux saisons, estivale et automnale de l’année 2004. Les valeurs de la température étaient conformes aux normes saisonnières et la salinité était faible à l'embouchure de l'oued Méliane suite aux apports d'eau douce. Les teneurs en sels nutritifs (nitrates, phosphates et ammonium) étaient très élevées et ont classé la qualité des eaux de la partie sud ouest de la baie de Tunis dans la catégorie "médiocre"... |

| This is a study on surficial sediments and bottom water physico-chemical characteristics of the San Jorge Gulf (SW Atlantic, Argentina)during spring 1999 - winter 2000 (first studied period), autumn 2001- summer 2002 (second studied period)and winter 2003 (third studied period), based on samples obtained during research cruises carried out on board of the INIDEP (Instituto Nacional de Investigación y Desarrollo Pesquero)research vessels. Environmental variables such as temperature, salinity, density, oxygen and bottom water chlorophyll a content as well as granulometric fractions, total organic matter, total organic carbon, total nitrogen, total phosphorous, chlorophyll a and phaeopigments in sediment concentration and depth were analyzed. The origen and... |

| ABSTRACT The objective of this study was to compare characteristics and properties of breast meat from spent Lohmann Brown layers (SP, 90 weeks old, n = 24) and those of commercial broilers (BR, 6 weeks old, n = 24). The breasts of both SP and BR were collected from a local processing plant, vacuum-packed in a plastic bag, and stored at -18ºC until further analyses. The SP showed a greater water-holding capacity, tougher and chewier texture (p<0.05). Both raw and cooked SP breasts comprised the greater total collagen but lower soluble collagen than those of BR (p<0.05). Muscle fibers of the SP, observed under scanning electron microscope, were small, with average fiber diameter of 37.85±1.40 μm, densely packed and surrounded by complex networks of... |

| Abstract Freeze drying is known as the excellent drying method for heat sensitive food products. In this research was aimed to determination of nutritional composition and physicochemical properties of fresh, freeze- dried and rehydrated rainbow trout (Oncorhynchus mykiss) mince. Sample groups were established as fresh trout mince, freeze-dried trout mince and rehydrated trout mince after freeze-dried. Proximate composition, pH, water activity, colour measurement, rehydration ratio, fatty acid and amino acid profiles were determined in the samples. As a result; nutritional composition, total aminoacid amounts and total MUFA amounts were different in fresh, freeze dried and rehydrated samples. However; the difference between the total amount of PUFA in... |

| This study was a small pen trial in which we investigated comparative effects of dietary sea urchin shell powder and feed additives on meat quality and fatty acid profiles of broiler breast meat. A total of 108 male broilers were assigned to 3 groups (control, 1% sea urchin shell powder, and 1% feed additives) with 3 replicates of 12 chicks per pen in a completely randomized design for 28 days. The following parameters have been investigated: proximate composition (DM, CP, EE, and ash), physicochemical properties (pH, TBARS, cooking loss and DPPH radical scavenging), meat color and fatty acid profiles. No remarkable effects between treatment and storage day were observed for proximate composition, physicochemical properties, meat color and fatty acid... |

| Abstract Effect of extrusion cooking using different corn starch contents on the physicochemical properties (expansion ratio, bulk density, color, hardness, protein in vitro digestibility, crude protein content, thermal properties and microstructure) of tuna meat-based extrudates was investigated. The results showed that the increased corn starch content led to darker, greener, yellower and lower crude protein content of extrudates, but no significant difference was observed in expansion ratio, bulk density and hardness. The lowest protein in vitro digestibility of 82.83±0.39% appeared when the corn starch content was 20 wt%. The results of DSC revealed that tuna meat with corn starch content of 30 wt% and 20 wt% had the highest and lowest denaturation... |

| Abstract Background: The use of electrostatic spray has the potential to optimize pesticide applications; however, further studies are required to verify its effectiveness. Objective: The objective of this work was to evaluate the electrostatic application system for the chemical control of weeds with glyphosate and adjuvant in different carrier volumes. Methods: The physicochemical properties of the spray solution, charge/mass relations, spray deposition on weeds, losses to the soil, effectiveness of weed control, and spray drift were evaluated. The field experiment was designed to have randomized blocks with four replications in a 2x2x2+2 factorial: the presence or not of electrostatic spray; with and without adjuvant (soybean lecithin + propionic... |

| Resumo: A dessecação de lavouras de soja tem sido utilizada, em algumas situações, para acelerar a senescência das plantas e o processo de secagem natural dos grãos, possibilitando escalonar e condicionar a cultura à colheita mecanizada com menor índice de perdas. Por desconhecimento ou na imi nência de períodos climáticos instáveis que impossibilitem a colheita, alguns produtores realizam a dessecação em estádios anteriores ao recomendado. Dessa forma, avaliou-se a influência da aplicação de dessecante em dife rentes estádios de maturação dos grãos de soja na qualidade dos grãos e do óleo. Duas cultivares (BRS 7980 e M8372 IPRO) foram avaliadas quanto à dessecação em cinco estádios fenológicos (R5.5, R6, R7.1 R7.3, R8.1), utilizando-se o dessecante... |

| Abstract: The objective of this work was to evaluate the reuse of sucrose syrup in pineapple (Ananas comosus) osmotic dehydration and the application of the spent solution in fruit dragée formulation. Osmotic dehydration trials were performed in five cycles (65° Brix/45°C/3 hours), directly reusing the osmotic solution, with only one intermediate reconditioning step. Variations in osmotic solution properties and in dehydration parameters were observed, as well as a low microbial load in the system. The spent solution was rich in vitamin C (30 mg 100 g-1). Pineapple dragée covered with red fruits and acai powders were obtained with the reconditioned spent solution used as an adhesion solution. The dragée presented high levels of vitamin C (176 mg 100 g-1),... |
