| La detección oportuna de deficiencias nutrimentales en hojas de plantas cultivadas permite tomar medidas correctivas inmediatas asi como predecir rendimientos. Las características espectrales y de textura de las imágenes se pueden utilizar para obtener información y correlacionarlos con el estado nutrimental de elementos esenciales que generan sintomatología similar en hojas de las plantas. En la presente investigación se estableció un experimento para medir las propiedades espectrales y característica texturales del cultivo de frijol con diferentes concentraciones de nitrógeno y magnesio de imágenes obtenidas con escáner. A partir de los valores de reflectancia se generaron modelos de regresión para asociar la concentración de nitrógeno y magnesio en el... |

| The aim of this study was to determine quality changes in petioles of self-blanching celery (Apium graveolens), cv. Golden Boy, harvested at 80, 87, 94, 101, 108, 115, 122 and 129 days after-transplanting (DAT). Total weight (TW), total length (TL), number of leaves per plant (LN) and by plant zone (external, LNZ E; middle, LNZ M; internal, LNZ I), and petiole length (PL) were evaluated at each harvest time. Petioles quality of each zone in the plant were analyzed in terms of: color (hue angle), texture (cutting force), total soluble solids content (TSS) and titratable acidity (TA). The petioles also were sensorially evaluated by descriptive analysis considering visual characteristics (flexibility, hollowness), flavor (typical flavor and odor) and texture... |

| Three isoproteic (crude protein content: 56%) diets with different fat levels (11%, 20%, and 26%) were fed to triplicate groups of triploid brown trout (initial average body weight of 1.5 kg), reared in seawater. At the end of 3 months of feeding, fish fed the high-fat (HF) diet were split into two groups: a triplicate group of fish received the low-fat diet and another triplicate group was kept unfed for a further 2-month period. Fish initially fed the low-fat diet during the first period were continued to be fed the same diet. Fish fed the medium-fat (MF) diet during period 1 were eliminated for period 2. At the end of each period, comparative whole body analyses, sensory and instrumental (texture and colour) analyses were made on fresh and smoked... |

| Different methods in use for cold smoking of salmon affect product yield and quality. The combinations of filleting time (pre or post), salting methods (dry or injection), salting targets (2.5 or 4%) and smoking temperatures (15 or 25 °C) were studied during 6 weeks of 4 °C cold storage. Salting method had the greatest influence on flesh quality. Injection salting led to 15% higher fillet yield, moderate to strong gaping score, softer texture, and paler fish compared with dry salting. Pre-rigor filleting reduced fillet gaping from a moderate to minor score, but only in dry salted fillets. Smoking at 15 °C reduced yield by 0.5% in injected salted fish, compared with 25 °C. The combination of pre-rigor filleting, dry salting and 15 °C smoking temperature... |

| A lean muscle line (L) and a fat muscle line (F) of rainbow trout were established (Quillet et al., 2005) by a two-way selection for muscle lipid content performed on pan-size rainbow trout using a non-destructive measurement of muscle lipid content (Distell Fish Fat Meter®). The aim of the present study was to evaluate the consequences of this selective breeding on flesh quality of pan size (290 g) diploid and triploid trout after three generations of selection. Instrumental evaluations of fillet color and pH measurement were performed at slaughter. Flesh color, pH, dry matter content and mechanical resistance were measured at 48 h and 96 h postmortem on raw and cooked flesh, respectively. A sensorial profile analysis was performed on cooked fillets.... |

| White breads with Yudane dough (Yudane bread) were made from commercial hard flour by the no first fermentation method. Yudane dough was prepared by mixing boiling water and flour at a ratio of 1:1. The dough at 20 and 40% (w/w, flour base) was added to the total bread dough. In the Yudane bread making method, an extended final proof, lower dough gas retention and gassing power, as well as specific loaf volume were observed compared to conventional bread making (control) without Yudane dough. Also, the moisture content of the Yudane breads increased with increasing water absorption for bread making. The total and reducing saccharide and maltose contents in the water-soluble fraction of Yudane bread also increased with the volume of added Yudane dough. The... |

| The freezing raw whole lobster is one of the products that are commercialized in the outer market; nevertheless the main factor that causes its rejection is the mass texture. Nodarse et al. (2005) determined that this product stayed with very good characteristics for its exportation until 10 months, after this period it began to detect a softening of the mass. There are different methods to determine the food texture, which is grouped in sensorial and instrumental. The objective of the present work was to determine the sensorial and instrumental texture of this product. Five raw whole lobsters by duplicate with different time storage (6, 8, 10, 12, 14 months) were evaluated using for it a paired comparison test. In order to measure the product firmness. It... |

| Crustaceans are harmed rapidly due to the post mortem different processes, specially the dark spot knew as melanosis or enzymatic darkening. Those spots are controlled by the sulfite treatments, but the potential dangers associated with the use of these compounds oblige to develope rigorous control methods. Besides, in these species are observed texture affectations during the storage time, changing to pasty mass and reducing its commercial quality. For these reasons, it was realized a durability study, analizing chemical, microbiological and sensorial parameters to the frozen products raw lobster tails and tail mass. The results indicated a shelf life of 21 months for the lobster tails and 18 months for the tails mass. |

| En el presente trabajo se presentan los resultados de la precisión de diferentes técnicas empleando una máquina Instron para medir la textura de spaghetti seco. Se comparó la técnica de flexión o doblado con los métodos que utilizan la celda de Kramer y la cuchilla simple de Warner-Bratzler. Se concluyó que en todos los casos las técnicas presentan buena precisión, pero el método de flexión ofrece los mejores resultados, con la ventaja adicional de que puede calcularse la fuerza de fractura en tensión como propiedad mecánica fundamental que caracteriza el producto. |

| Se estudió la influencia de diferentes combinaciones de fibra de soya (1,5; 2,0; 2,5 y 3 %) sobre algunas características de calidad de las salchichas. Los componentes constantes para todas las variantes fueron: 55 % de carne de cerdo, 2,39 % de sales (sal común, sal de cura, tripolifosfato de sodio y ascorbato de sodio) y 1,20 % de condimentos. Además se tomó como referencia la formulación de una salchicha sin fibra. A las salchichas se les determinaron proteínas, humedad, grasa, pH, cloruros y nitritos. El perfil de textura se midió mediante una prueba de compresión doble en el Instron. Las mermas por cocción se estimaron como el porcentaje de peso perdido durante la etapa de cocción. Los parámetros del perfil de textura, mermas por cocción y los... |

| Land use/cover classification is one of the most important applications in remote sensing. However, mapping accurate land use/cover spatial distribution is a challenge, particularly in moist tropical regions, due to the complex biophysical environment and limitations of remote sensing data per se. This paper reviews experiments related to land use/cover classification in the Brazilian Amazon for a decade. Through comprehensive analysis of the classification results, it is concluded that spatial information inherent in remote sensing data plays an essential role in improving land use/cover classification. Incorporation of suitable textural images into multispectral bands and use of segmentation‑based method are valuable ways to improve land use/cover... |

| ABSTRACTThe conclusion of the dam project located in Alqueva, in Southern Portugal, has resulted in a significant increase of new irrigated areas, since 2006. This has meant that, in recent years, there have been progressive flora changes in farming systems traditionally implemented in the Alentejo region. The present work has analyzed the weed flora in an early stage of these changes, and the impact of environmental factors on the distribution of natural vegetation under Mediterranean climate conditions in the influence area of Alqueva. In 2007, 105 floristic surveys were carried out in autumn-winter crop plots or other soil use, and 264 species were identified. Families with higher expression were: Asteraceae, Poaceae, and Fabaceae. Only three species... |
