| Tomato (Lycopersicon esculentum Mill.) fruits, cv. Santa Clara, were harvested at the breaker stage from commercial fields in Brazlândia, Brazil, to investigate the ability of 1-methylcyclopropene (1-MCP) to retard tomato fruit ripening. Fruit without external blemishes were graded for size (diameter = 80±5 mm) and mass (m = 130±10 g), placed inside hermetically sealed boxes, and 1-MCP was applied for 12 hours (T = 22±1°C; RH = 80-85%) at four different concentrations: 0 (control), 250, 500 and 1000 mL.L-1. Fruits were held at ambient conditions (T = 23±2°C; RH 80-85%) for 2 days and then stored inside a cold room (T = 20±1°C; RH = 85-95%). Every 3 days, during a 15-day period, fruits were analyzed for firmness, total soluble solids, titratable acidity,... |

| Las atmósferas controladas alargan la vida en estante del tomate, permitiendo su cosecha en estados de madurez más avanzados y a su vez afectando su calidad. El objetivo de este experimento fue estudiar los efectos que atmósferas controladas con bajas concentraciones de oxígeno y libres de dióxido de carbono y etileno, producen sobre el color, la firmeza y los principales componentes del sabor de frutos de tomate cultivar Diva. Durante abril de 1998, frutos cosechados con grado de color 3 (USDA) en INTA Balcarce (Argentina) fueron almacenados en frascos herméticos de 3 L a 12°C durante 36 días. El diseño fue completamente aleatorizado con tres repeticiones. Cada frasco poseía cuatro frutos, los que constituyeron la unidad experimental. Los tratamientos... |

| Presently there is a growing interest in the production and marketing of wild boar meat, and to attend a differentiated consumer demand the quality attributes of this product should be well established. To characterize the quality of wild boar meat in comparison to commercial pork, post mortem changes in the longissimus dorsi and semimembranosus muscles were determined by pH and temperature decline, and color (CIE L*a*b*) measurements. Water holding capacity (WHC) was determined by the compression method and the exudate loss (EL) by the drip loss test. Decline in longissimus dorsi muscle pH of wild boar was gradual and in the pork it was faster and more extensive. Temperature differences were observed in some post mortem times, and the lowest values were... |

| The objective of this study was to evaluate the effect of different supplementation levels of Rhodocyclus gelatinosus biomass on the performance and pigmentation of broilers. Cobb broilers were raised in pens and were fed a sorghum-based diet until 35 days of age. At the 36th day of age, ninety-six birds were randomly distributed to four treatments consisting of experimental diets with different supplementation levels of Rhodocyclus gelatinosus biomass (0, 75, 150 and 300 ppm) added to the finisher basal diet, which were given for seven days. A completely randomized experimental design was used, with four treatments, four replicates and six broilers per parcel. Birds and diets were weighed at the 36th and at the 42nd day of age for performance analysis.... |

| We conduct a within-sample test of hypothetical bias and parameter equality between a hypothetical stated choice (SC) experiment using pictures and a real choice (RC) experiments using products. With exception of the none-of-these alternative-specific dummy, we cannot reject parameter equality between the two datasets. However, when we estimate the models separately with no parameter restrictions, the SC experiment gave WTP estimates that were approximately 50 percent higher and marginal WTP estimates that were almost two times as high as the corresponding estimates from the RC experiment. However, even though the monetary value of the WTP disparity was large, the disparity between the WTP estimates from the two data sets was not statistically significant. |

| Blackberry (Rubus L.) is a naturally growing fruit in Anatolia. Consumption of fresh and frozen blackberries has increased in the past few years in Turkey. The aim of this study is to analyze blackberry at three levels of ripeness taking into account some physical and chemical properties (color, dry matter, soluble solids, total sugar, titratable acidity, pH, total phenolics, total anthocyanin, and minerals) in order to understand this behavior during the ripening process. Blackberry fruits were harvested at green, red and ripe (mature) stages. The determination of fruit maturity was based on fruit surface color. The dry matter, total phenolics and Hunter L, b values decreased but soluble solids, total sugar and total anthocyanins increased with maturity.... |

| To evaluate the effect of different levels of qualitative feed restriction (0, 5, 10, 15 and 20%) on pork quality and muscle morpho-histochemical characteristics, 60 castrated male swines were used. Ten animals were slaughtered at 89 kg BW. Other 50 pigs were fed experimental diets and slaughtered at 128 kg BW. Qualitative restriction increased pH45, and water holding capacity, and reduced the redness, yellowness and cholesterol concentrations of Longissimus lumborum. Quadratic tendency for oleic acid contents of loin and fiber cross-section area of Multifidus dorsi (P=0.08) were observed, with maximum point at 11-12% of restriction. No effect (P>0.1) on percentage of M. dorsi fibers SO, FG and FOG was found. The meat from 128-kg-BW pig showed... |

| Chickpea is a well recognized source of vegetable protein, especially in underdeveloped areas of the world. Mexican chickpea is highly priced in the international market due to its desired quality. The Northwest of Mexico, especially Sonora and Sinaloa, are also recognized for the quality of chickpea, where a high percentage of the annual production is placed in the international market. Among the various characteristics of high-quality chickpea, color is one of the most important, since it influences both: the selection of new improved varieties at the experimental research stations, and also the price at the international market. The purpose of this study was to evaluate two objective instrumental methods of color determination as related to sensory... |
