| Abstract The changes in concentration of vitamin C, enzymatic and antioxidant activity during the ripening of two soursop selections (G1 and G2) at room temperature (22 ºC) and refrigeration (15 ºC) with an HR 85% were evaluated. The content of soluble protein, the activity of catalase (CAT), superoxide dismutase (SOD), peroxidase (POD), the concentration of vitamin C, as well as the antioxidant activity was evaluated by DPPH, ABTS and FRAP methods. The initial soluble protein concentration of the G1 and G2 selections diminished at 22 and 15 °C during ripening. Fruits stored at 22 °C showed the highest CAT activity. The maximum activity of SOD was recorded on the sixth and fourth day in fruits stored at 22 and 15 ºC, respectively. Fruits stored at 22 °C... |

| ABSTRACT Onion is the third most consumed vegetable worldwide, such as potatoes and tomatoes. Its conservation is influenced by temperature and humidity, and greatest losses occur at postharvest due to lack of storage infrastructure. Thus, the aim of this study was to evaluate the effect of partial cooling in vertical silo on postharvest conservation of cured onion bulbs cultivar Bola Precoce. The experimental design was completely randomized, with six replicates, arranged in split plot scheme. Plots consisted of two storage conditions: onion bulbs stored in silo 1 at room temperature (T1) and bulbs stored in silo 2 with artificial cooling (T2). Subplots were two periods of bulb removal from storage (0 and 14 days). We evaluated peel color, using chroma... |

| Due to the important economic activity of oyster production in France, microalgal toxic events represent a significant constraint for shellfish farmers who face closures of bivalve production-sites. The frequency of closures of 3 weeks or less represents half of the total closures along the French coasts. Cold storage could be a simple and affordable solution for temporary and short-term storage before commercialisation. A stock of marketable Pacific oyster Crassostrea gigas was therefore stored during 22 days in non-immersed conditions at 3 degrees C with 100% humidity. At the end of the experiment, the oyster mortality rate remained at a low level of less than 3.5%. The sensory attributes, odour, appearance, texture and flavour, did not show significant... |

| El objetivo del presente trabajo fue definir la vida útil de un queso tipo crema de alta humedad a partir de leche entera de búfala envasado en potes de polipropileno de 200 mL y conservado a la temperatura de 4 ºC. Para definir la durabilidad del producto se tomaron como criterio de rechazo, la evaluación sensorial y la calidad higiénica- sanitaria, como variables de control fueron consideradas el desarrollo de acidez y valor del pH. La estimación de la durabilidad se efectuó por el método gráfico para datos incompletos de fallo utilizando la distribución de Weibull. Se concluyó que alteraciones detectadas por los evaluadores en el olor y sabor resultaron la primera causa de deterioro. La vida útil del producto fue de 12 días. |

| Serum is widely used for the purpose of monitoring and diagnosis support for most of poultry diseases. In the case of the serum plate agglutination test (SPA), commonly used to detect antibodies for Salmonella Pullorum (SP), Mycoplasma gallisepticum (MG) and Mycoplasma synoviae (MS), serum cannot be frozen because it may result in false positive. Without freezing, serum can last only for a few days. In this experiment, glycerin was evaluated as a serum preservering agent. About 50 samples for each disease and analyzed by SPA test previously were separated. Glycerin was added to serum from commercial chickens, with and without antibodies for SP, MG and MS, in the proportion of 1:1 (serum:glycerin) and kept at refrigerated conditions (2 to 8 ºC). For four... |

| ABSTRACT: Preservation and use of spermatozoa that have been recovered after death can extend the use of genetically superior animals. The objective of this study was to evaluate the maximum period for which ovine spermatozoa could be successfully stored in refrigerated dilution medium post-mortem, with or without added seminal plasma. Three samples of spermatozoa collected in an artificial vagina from 10 rams, or from the tails of four epididymes from the same rams at the time of death (G0) and six (G6), twelve (G12), twenty-four (G24) and forty-eight (G48) hours after death were used. After recovery, the spermatozoa were refrigerated at 5°C in either control medium (CM) or control medium plus 20%homologous seminal plasma (SP) and evaluated for 72 hours... |

| Cactus stems, the cladodes of Opuntia spp. cacti, are consumed in Mexico and other countries due to their fresh and herbaceous flavor, and because of their widely known nutraceutical benefits. In order to extend the postharvest life of this vegetable, the effect of a modified atmosphere packaging (MAP) was studied in cactus stems of the cultivar Atlixco stored at 4 ± 1 °C for 20 days under three types of atmospheres: (1) air (passive atmosphere), (2) 5 kPa O2 + 4 kPa CO2, and (3) N2. During storage, the titratable acidity decreased and the color of cladodes became darker and less green; however, the 5 kPa O2 + 4 kPa CO2 atmosphere was able to preserve both quality characteristics. All modified atmospheres reduced weight loss (from 8 to <2%) and the... |

| ABSTRACT Mineral nutrients have important role in plant metabolism, acting on specific vital metabolic pathways for the cell. Among the nutrients, we highlight silicon (Si), for promoting growth, improving post-harvest quality and plant productivity, as well as being able to induce resistance to pest and disease. In this sense, this study aimed to evaluate the productivity and post-harvest quality of strawberry fruits cultivars Aromas and Albion cultivated in organic system with four doses of foliar applications of SiO2 in pre-harvest (0, 5, 10, 15 g L-1), and refrigerated storage (8 days under refrigeration and 1 day at room temperature). The valuated traits were: mass loss, fruit mass, productivity, fruit firmness, soluble solids, titratable acidity,... |
