Air drying of macauba fruits: maintaining oil quality for biodiesel production Agronomy
Silva, Gutierres Nelson; Grossi, José Antônio Saraiva; Carvalho, Marcela Silva; Kuki, Kacilda Naomi; Goulart, Samuel de Melo; Pimentel, Leonardo Duarte.
Macauba fruits are oil-rich drupes with high moisture content at harvest. This feature can affect the chemical properties of the oil and increase the costs of biodiesel production. Therefore, it is necessary to adopt postharvest strategies to ensure oil quality. The aim of this work was to evaluate the effect of drying macauba fruit on the quality of the pulp oil. Husked and dehusked fruits were dried at 60°C and then stored. At 0, 15, 45, 100, and 180 days after storage, fruit samples were retrieved, and the oil from the pulp was evaluated for physicochemical parameters. The removal of the husk from the fruits considerably reduced the drying time compared to that of the husked fruits. Drying prevented deterioration of the fruit even after 180 days of...

Características físicas e químicas do fruto da sapota em diferentes estádios de maturação. Repositório Alice
BRITO, E. S. de; NARAIN, N..
No presente trabalho foram estudadas, em três estádios de maturação, as características físicas e químicas da sapota (Manilkara zapota L.P. Royen), bem como o seu comportamento pós-colheita durante o armazenamento, no seu ambiente natural e sob refrigeração. Com o avanço do amadurecimento, foi verificado um aumento no teor de açúcares redutores, acompanhado pela redução dos teores da acidez total e de taninos. Os frutos que não tiveram o pedúnculo removido durante a pós-colheita apresentaram um tempo de armazenamento superior aos frutos que tiveram o pedúnculo removido. Os frutos armazenados sob refrigeração tiveram uma maior retenção do peso em relação aos frutos armazenados em condições ambientais.

CASTOR BEANS QUALITY SUBJECTED TO DIFFERENT STORAGE TEMPERATURES AND PERIODS REA
Goneli,André L. D.; Corrêa,Paulo C.; Oliveira,Ana P. L. R.; Hartmann Filho,Cesar P.; Oba,Guilherme C..
ABSTRACT The control of the temperature of the storage air have the ability to improve a better preservation of some types of agricultural products. However, the most effective temperature for storage as well as the duration of storage varies between products. Therefore, special attention should be concentrated on the storage temperature and its effects on the integrity and longevity of the produce. The objective of the present study was to evaluate the effects of storage temperature and storage period on the quality of castor beans. Castor seeds with a water content of approximately 6.1% (w.b.) were stored for 180 days at temperatures of 15, 25 and 35 °C. The quality of the seeds was evaluated every 45 days throughout the study period by measuring dry...

DEFORMATION OF PEACHES SUBMITTED TO CYCLIC LOADING USING THE DISCRETE ELEMENT METHOD REA
Pinto,Eduardo M.; Ferraz,Antonio C. de O..
ABSTRACT This study aimed to use and validate a simple contact force model that describes the behavior of peaches stored in a wooden box, loaded cyclically, by using the discrete element method. The Kelvin-Voigt contact force model was used and the cyclic loading in the simulation was performed with an amplitude of 1 mm and frequency of 12 Hz for time intervals of 3600, 5400, and 7200 s. The laboratory test was performed with a peach box attached to a vibrating table by applying the same excitation conditions used in the simulation. For validation, model results were compared with those from the laboratory test by using deformation values of fruits in the contact regions. To measure this deformation, we adapted the methodology for determining the radius of...

Ethylene and 1-methylcyclopropene action over senescence of nasturtium flowers Horticultura Brasileira
Silva,Tania P; Finger,Fernando L.
ABSTRACT: This work describes ethylene and 1-methylcyclopropene (1-MCP) action on post-harvest shelf life of four development stages of nasturtium flowers. To reach this goal, we carried out three experiments. In the first and second experiments, we studied five ethylene (0; 0.1; 1; 10; 100 and 1000 μL/L) and three 1-MCP concentrations (0.25; 0.5 and 0.75 μL/L), respectively. In the third experiment, 1-MCP was followed by combined with ethylene (only 1-MCP; only ethylene; and 24 hours of exposure to 0.75 μL/L 1-MCP followed by 24 hours of exposure to 100 μL/L ethylene). All experiments had two control treatments, one keeping non-exposed flowers inside and another outside exposure chambers. Experiments were set in factorial design, in complete blocks at...

Farmers' Post-Harvest Grain Management Choices under Liquidity Constraints and Impending Risks: Implications for Achieving Food Security Objectives in Ethiopia AgEcon
Gabriel, Abebe H.; Hundie, Bekele.
The purpose of this paper is to explore into the relationships between farmers' post-harvest grain management practices/capacities on the one hand, and liquidity constraints and impending risks on the other, in the context of achieving food security objective at household and national levels. The findings are primarily based on a household survey data from 300 randomly selected major food grain producing peasant households in three rural districts of Ethiopia. Results indicate that farmers perceived post-harvest grain loss as an imminent risk, and that instant sales of grains after harvest are triggered by temporary but immediate liquidity preferences to meet various obligations in the absence of or limited sources of cash other than crops sales, and by an...

Gamma radiation in papaya harvested at three stages of maturation Scientia Agricola
Pimentel,Rodrigo Meirelles de Azevedo; Walder,Julio Marcos Melges.
Papaya is a fragile, perishable fruit, highly accepted worldwide. To keep the quality of papaya from harvest to the consumers, conservation techniques are often used; among them is the application of gamma irradiation. The objective of this work was to evaluate gamma irradiation in papayas harvested at three degrees of maturation, in order to increase shelf life. Papayas were harvested in perfect quality conditions and selected by skin coloration into three distinct degrees of maturation: maturation 0, or beginning of yellow coloration; maturation 1, yellow stripes more developed, and maturation 2, one third yellow. Half of them were irradiated with 0.75 kGy, while the other half became control treatment. They were analyzed in four periods of conservation,...
