| Many texture measures have been developed and used for improving land-cover classification accuracy, but rarely has research examined the role of textures in improving the performance of aboveground biomass estimations. The relationship between texture and biomass is poorly understood. This paper used Landsat Thematic Mapper (TM) data to explore relationships between TM image textures and aboveground biomass in Rondônia, Brazilian Amazon. Eight grey level co-occurrence matrix (GLCM) based texture measures (i.e., mean, variance, homogeneity, contrast, dissimilarity, entropy, second moment, and correlation), associated with seven different window sizes (5x5, 7x7, 9x9, 11x11, 15x15, 19x19, and 25x25), and five TM bands (TM 2, 3, 4, 5, and 7) were analyzed.... |

| Blueberry is a widely consumed fruit with major economic value, appreciated due to its characteristic flavor as well as health benefits. The present work aimed to evaluate the effect of several production factors and storage conditions on some chemical and physical properties of blueberries. Some physical and chemical characteristics (moisture, acidity, sugars, color and texture) of blueberries from three cultivars, originating from five different locations and conventional or organic farming, were evaluated. The variation of the properties along time was also evaluated for storage at room temperature and refrigeration. Moreover, artificial neural network models were developed to estimate the physical-chemical characteristics of the blueberries, as... |

| ABSTRACT Sensory and instrumental analyses evaluated the meat and fat characteristics of feedlot-finished steers fed a diet containing cottonseed. Global impression, texture, meat color, and fat color were assessed. Thirty Nellore bulls with an average age of 30 ± 6 months and initial body weight of 382.7 ± 28.4kg were kept in feedlot stalls and fed the following cottonseed levels: 0; 2.22 %; 4.44 %; 6.66 %; 8.88 %; 11.11 % of the dietary dry matter. The cottonseed used in this experiment had an average free gossypol content of 4.5g/kg of cottonseed. The overall impression of the samples, assessed by the triangle test for difference, did not differ for more than 62 % of the panelists (P>0.01). The shear strength of roasted meat varied from 6.00 to... |

| The goal of this study was to evaluate sous vide fish and assess the influence of time and temperature on the pasteurization process through quality parameters. The raw material (tambaqui fillets) and the sous vide underwent physical, physicochemical, and microbiological analyses. A sauce was prepared containing soy sauce, water, horseradish and garlic flakes. The product's pasteurization parameters of time and temperature were defined according to a 22 central composite rotatable design (CCRD), and the dependent variables were water holding capacity (WHC) and instrumental texture aiming at obtaining high WHC values for the product to maintain the desired juiciness. The microbiological analysis required by legislation have indicated that the fish fillets... |

| Milk calcium concentration is a factor related to cheese texture, an important rheological property of cheese quality as perceived by consumers. This study aimed to evaluate the effect of different pH conditions (5.8 and 6.6) and calcium addition (0, 150, 300 ppm of CaCl2), on yield and nutrient retention of the clots obtained and on the texture of Minascured cheese. Clots were analyzed for wet and dry yield, percentage content and retention of protein, fat and calcium. The texture of the cheese was evaluated by instrumental and sensorial tests. No differences were observed on the wet and dry yields, or on the protein content, fat and calcium retention of clots produced in the different experimental conditions. The instrumental evaluation showed that... |

| The objective of this study was to evaluate the inclusion of minced fish (MF) (0, 20, 40, 60, 80 and 100%), obtained from Nile tilapia filleting waste, in sausage and determine their physicochemical, nutritional and sensory properties. The sausages showed a decrease in protein and increase in fat content with increasing inclusion of MF. The nutritional quality of the products was high, with digestibility over 85%. The parameters of texture instrumental and yellow color (b*) decreased with the increasing inclusion of MF. The sensory evaluation of the color showed that the maximum level of inclusion of MF was not well accepted by the panelists. The sausage with the best acceptance for the flavor attribute was those with 60% of MF. The results showed good... |

| ABSTRACT Whey has proteins of high biological value, which has been used as an ingredient in the elaboration of yogurt, milk beverages and as protein concentrates. Food extrusion stands out as one of the most efficient cooking techniques, allowing a number of product types, from soluble flour to convenience products, such as snacks, which have high acceptability by the consumers. Products processed by extrusion, such as those expanded by frying (pellets), have high carbohydrate content, and its enrichment with protein can favor its nutritional aspect. This study aimed to use the whey protein concentrate (WPC) in combination with corn grits in the preparation of pellets. Absolute density, density of expanded pellets, color, crispness index, and pellet... |

| The use of liquid whey to replace water (at 0, 25, 50, 75 or 100%) in a restructured cooked ham formulation was studied and several technological and sensory quality properties were determined. The test results showed no statistically significant differences (P < 0.05) in weight loss attributes (cooking yield, storage loss, reheating loss and refreezing loss) and instrumental texture (TPA test) parameters. However, for CIELAB color, samples were (P > 0.05) less reddish (a* value reduction) and more grayish and yellowish (lesser C* and higher h values) with higher whey additions. A lower (P < 0.05) flavor preference among samples with 25 and 50% liquid whey substitution was observed. Also, the sensory color was different (P < 0.05) in the... |

| The aim of the study is to evaluate, by using sensory methods, Chanco cheese texture by means of quantitative descriptive analysis to project a sensory map based on multivariate analysis. Samples of Chanco cheese (two different commercial brands) were used. Sensory evaluation was undertaken by a trained panel (n = 13), using quantitative descriptive analysis. The sensory profle includes the properties of springiness, hardness, friability, deformability, adhesiveness and cohesiveness. Sensory scales from one to seven were used to express the intensity perceived for each property. Based on the results, it was possible to observe the formation of a main group, comprising of cohesiveness, friability, springiness and adhesiveness. Other groupings were formed... |

| The aim of this research is to evaluate the sensory texture and influence of calcium chloride concentration on the physicochemical and sensory characteristics of tofu. Samples were prepared from reconstituted soy milk (12% total solids). Calcium chloride at two different concentrations (0.3 and 0.5%) was used as a coagulant. pH, fat content, humidity and total solids were measured. Quantitative descriptive analysis was used to evaluate the sensory properties of springiness, hardness, friability, deformability, adhesiveness and cohesiveness. Correlations were significant (P < 0.05) between cohesiveness and hardness and between pH and adhesiveness. Using correspondence analysis, the panelists described tofu to be firm and elastic when using the lowest... |

| Abstract In this research, the effects of cooking by convection oven and cooking by sous-vide method on the physicochemical, textural, sensorial and microbiological of gluteus medius cuts were investigated. For the sous-vide method, the meat was vacuumed sealed in special packaging material (Mylar®Cook) before being stored at + 1 °C for 0, 15, and 30 days. The samples cooked with the sous-vide method had higher moisture content (P < 0.001) and lower cooking loss than oven roasted samples. TBARS content was affected by cooking method (P < 0.01) and storage time ( P < 0.01). The 2-thiobarbituric acid reactive substances (TBARS) values of the convection oven samples were higher than those cooked with sous-vide method. The WBSF values were affected... |
