| The effects of drying conditions on the shrinkage of Coffea Arabica L., cultivar Catuaí Vermelho, were studied. An exponential model derived from the kinetic model was used to describe the shrinkage kinetics. In addition, an equation was proposed to describe the relationship between the superficial areas and weights of the coffee berries. Coffee berries were dried at temperatures (T) of 35, 45, 55 and 65ºC and at relative humidities (φ) of 25, 35, 45 and 55%, forming 16 different sets of conditions, with an initial moisture content for all conditions of 2.27 dry basis (d.b.), dried until 0.11 d.b. Changes in the product dimensions were measured continuously during drying. Surface area-to-volume ratio values increased with moisture content decrease. The... |

| 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... |

| In the Amazon region, there is no information on the fertilization of banana plants with boron (B). Besides this, the extractant (hot water) currently used to test B concentrations has many limitations. The aim of this work was to study the effect of B on the fruit yield and quality of banana plants of the Cavendish (AAA) sub-group, grown in dystrophic Yellow Latosol (Oxisol or Xanthic Ferralsol), in the Amazonas State, Brazil. The experimental design was completely randomized split plot in a 4 x 2 factorial scheme, composed of four B rates (0, 4, 8 and 12 kg ha-1) and two harvest cycles (sub-treatments), with four replicates. The B availability in the soil was determined by three extractants: Mehlich 3, hot water and KCl 1.0 mol L-1. The application of B... |

| ABSTRACT The increasing consumer demand for fruit quality justifies the development of researches that combine orchards management and consumers’ perception of the quality of the product. The aim of this study was to evaluate the effect of nitrogen fertilization combined with green pruning intensity on fruit quality of ‘Chimarrita’ from high density peach trees during three consecutive harvest seasons. For this purpose, urea composed of different nitrogen rates (0, 40, 80, 120, 160, 200 and 240 kg.ha-1.year-1) was applied, under two intensities of green pruning (annual – once per season; or continuous – four times per season) in a factorial scheme (7 × 2). Fruits have been subjected to physical, chemical and sensorial analysis, made by 60 non-trained... |

| Lengthening the post-harvest life of fruits from temperate climates is one of the greatest challenges of modern agriculture, which aims at diminishing the losses and increasing the offer period of the product in national and international market. The use of eatable pellicles has been explored to cover fruits, since its usage represents an economical advantage, due to its low price and reduction of post-harvest losses. Thus, the aim of this work was to evaluate the quality of blueberry, cultivar Florida M, produced in an organic production system and covered with eatable covering based on kefir grains associated with different storage temperatures. Thus, it was observed that the most efficient treatment to reduce blueberry post-harvest loss was the... |

| In the present work one determined the threshold pile height below which cracking and other deformations do not occur in products with low apparent density such as lettuce, collard greens and bell pepper. Initially the threshold pile height was sought applying decreasing compression stresses equivalent to pile loads of 160, 120 and 80 cm, with four replicates in four hour assays. The safe threshold pile height which protects the products against cracking rupture in these three commodities were of 80 cm. In a complementary study, plastic and elastic deformations induced by this safe pile threshold height were measured. The irreversible deformation, plastic deformation component, were lower in bell pepper (3.8 %), medium in lettuce (4.23 %) and had the... |

| Abstract Polysaccharide-based coatings are an alternative to synthetic coatings for fruit conservation. In this study, we aim to evaluate the physical and chemical characteristics of breadfruit starch for coating using glycerol, sorbitol, and mannitol as plasticizers. We applied coatings composed of 7% starch and 2% plasticizers to cherry tomatoes, and evaluated the storage during 12 days at a temperature of 18 °C. The breadfruit starch had an amylose content of 27.17%, granular size of 0.85-0.87, a gelatinization temperature of 75.10 °C, characteristics of standard starch type B and low syneresis. Coatings composed of glycerol and sorbitol showed a reduction in mass loss and delayed ripening. Glycerol and sorbitol are recommended for preparing coatings... |

| ABSTRACT: The gap in the storage industry has brought a series of problems for the agro industrial market today, as its ability to directly infer the quality of newly collected material. The present study was carried out with the objective of evaluating the quality of second crop corn harvested with different water contents depending on the period until drying. The corn grains were harvested with moisture contents of approximately 28.5; 22.4; 21 and 19%, and subjected to temporary storage for ten days, simulating the time between harvest and drying. In the period, every two days the quality was evaluated by determining the specific mass, electrical conductivity, color, crude protein content, ethereal extract, ashes and carbohydrates. Based on the obtained... |
