The conditions of cultivation and the management of fertilization influence the productivity and the post-harvest quality of cucumbers in an expressive way. In this sense, the aim of this study is to evaluate the physical, chemical and sensorial post-harvest quality of cucumbers for canning purposes submitted to different doses of nitrogen fertilization. The experiment was carried out in a greenhouse at the Goiano Federal Institute (IF Goiano), campus Urutaí and After harvest, the material was sent to the food technology laboratory located in the campus. The soil of the area is classified as Red Latosol according he cucumber cultivar used was the Cucumis sativus L. Kybria F1 hybrid, most suitable for the processing of canned foods. The experimental design was randomized blocks and five treatments (nitrogen doses 0, 50, 100, 150 and 200 kg ha-1), and four replications. The physical parameters fruit length and diameter, fruit fresh matter, production per plant, titratable acidity (TA), pH, soluble solids (SS), moisture, ash content, and SS/TA ratio were evaluated. A sensory analysis was performed using acceptance and ordering-preference tests, in addition to an instrumental evaluation of texture. The application of different doses of nitrogen to cucumber in a protected environment influenced the production per plant and the physical-chemical characteristics of the fruits. However, the sensory quality was not affected. The doses 100 and 150 kg ha-1 of nitrogen is recommended for the production of canned cucumber

The association between mineral fertilizer and biofertilizers can contribute to guavas quality. An experiment was carried out in order to assess, over the days, 'Paluma' guavas physical-chemical quality in function of nitrogen fertilizer and biofertilizer doses. It was adopted a randomized blocks with treatments distributed in a factorial 5 x 2 x 5 referring to evaluation days post-harvest (0, 3, 6, 9 and 12), nitrogen fertilization (50 and 100% culture recommendation) and application of bovine biofertilizer doses by fertigation (0.0, 2.5, 5.0, 7.5 and 10.0%). The physical-chemical quality of 'Paluma' guava fruit was influenced by the association between liquid bovine biofertilizer and nitrogen fertilization. This combination increased soluble solids, titratable acidity, ratio, vitamin C, pH, firmness and loss of fresh mass, but did not affect the pulp percentage. The bovine biofertilizer, together with mineral fertilization, is important to increase the post-harvest quality of 'Paluma' guava.

The amount of mango production in Indonesia is quite high, but the quality of postharvest mangoes is still quite low. The quality of the fruit will decline due to contamination; one of the contaminants is fungi. The way to reduce the damage of postharvest products is by coating applications. The purpose of this study was to study the physical, chemical and antifungal activities of harumanis mangoes’s quality which had been given coating during storage that could cause postharvest losses of harumanis mangoes. There are 3 treatments, each of them are respectively the provision of corn based coating  6% tobacco extract, 8% tobacco extract and 10% tobacco extract. The physical and chemical properties of the antifungal coating of tobacco extract made from corn coating for post-harvest damage on harumanis mangoes were obtained by weight loss, texture, colour, respiration rate, vitamin C and total dissolved solid. Preventing coating can prevent damage after harvest and protect the harumanis mango; therefore the quality of the mangoes can be maintained. The best results from the priority with the largest diameter inhibition zone were given corn starch 10% tobacco extract. Then the higher the concentration of extract used, the greater the diameter of the inhibition zone obtained. Based on all the tests performed (physical, chemical, and antifungal) the best treatment from the treatment was obtained that consisted of mangoes with antifungal layers of corn starch 10% tobacco extract. Because the P3 obtained the best results in maintaining physical, chemical content and fungi for 15 days.

Peach is a climacteric highly-perishable fruit whose post-harvest preservation relies largely on cold storage. The combination of the last with other technologies allows to extend the shelf life of this product. One alternative is the utilization of salicylic acid, a natural compound involved in many physiological phenomena such as resistance against diseases and ripening. Considering these facts, the objective of the present work was to evaluate the effect of pre-harvest application of salicylic acid solutions on the quality of ‘Chimarrita’ peaches during post-harvest cold storage. The experiment was conducted at the Federal University of Pelotas/RS, in the campus of Capão do Leão/RS - Brazil. The application of salicylic acid solutions was performed by direct pulverization on the fruits, 30 days prior to harvest. The concentrations were: 0,0 (control); 1,0; 1,5; and 2,0 mM. After harvest, the fruits were stored in a cold chamber at 1,0 ± 0,5°C and 85-90% RH, for 30 days. The analyses were performed at the following cold storage periods (plus 2 days at room temperature of 20°C to all treatments, in order to simulate commercialization conditions): 10 (+2) days; 20 (+2) days; e 30 (+2) days. The variables evaluated were: mass loss (%); flesh firmness (N); DA index; color (L, a*, b* and hue angle); wooliness incidence (%); rot incidence (%); total soluble solids (°Brix); pH; titrable acidity (% of organic acids); and ratio. The salicylic acid doses and/or the cold storage periods had significant effects on all the evaluated parameters. For most of the parameters analyzed, the intermediate dosis of 1mM (and also 1,5mM) of salicilic acid showed the most promising results. Therefore, the application of salicylic acid solutions 30 days prior to harvest is a technique which can be combined to cold storage in order to shift the quality and the shelf-life of ‘Chimarrita’ peaches.

Brazil has a large variety of native and exotic fruit species, including the gabiroba, which can be sources of income for the population. The objective of this study was to evaluate the post-harvest behavior of gabiroba fruit by maturity stage and storage temperature. The fruits were divided into two lots and stored at temperatures of 6, 12, 24 and 30°C. The first batch was used for the physical and chemical analysis of acidity, soluble solids, firmness, percentage of green color, and visual analysis; this batch was composed of green and yellow-green fruit. The second lot was intended for breath analysis, composed of green, yellow-green, and yellow fruits. The experiment was conducted in a completely randomized design with five replications. Data were analyzed using descriptive statistics. Considering the evaluated characteristics, the gabiroba soluble solid/titratable acidity ratio values should be approximately 4.0 for the fruits to be considered acceptable for consumption. For the preservation of the post-harvest quality of gabiroba, it is indicated that the harvest is carried out at the green stage of maturation and that they are stored at a temperature of 6°C. The highest respiratory rates were observed in fruits harvested at the yellow stage, not being recommended its storage.

Until recently, fungicides were used exclusively for disease control; however observations of physiological effects brought a new concept to the use of these products. Strobilurins have positive physiological effects on crop yield, due to the increase of liquid photosynthesis and better hormonal balance. However, boscalid complements the action of these fungicides, applied alternately or together. The aim of this study was to evaluate the effect of strobilurins (azoxystrobin and pyraclostrobin), boscalid and the mixture of these on the physical-chemical quality of net melon fruits (Cucumis melo var. Reticulatus). The experiment was conducted in the municipality of São Manuel (SP), using the hybrid of Cantaloupe M2-308 net melon, the experimental design was in randomized blocks with five replicates. The treatments used were: T1 - control; T2 - azoxystrobin 60g ha-1 of active principle (a.p.); T3 - boscalid 75g ha-1 of the a.p.; T4 - pyraclostrobin 50g ha-1 of the a.p.; T5 - boscalid (37,5g ha-1) of the a.p. + pyraclostrobin (25g ha-1) of the a.p. The first application of the treatments was carried out at fourteen days after the transplanting of the seedlings and the others at seven day intervals, totaling eight applications throughout the cycle. Two fruits of each plot were collected, which were identified for analysis in the laboratory. The following characteristics were evaluated: fresh fruit mass; mesocarp thickness, pulp texture, peel trajectory, pH, titratable acidity, soluble solids and the ratio. The results were submitted to analysis of variance and the averages compared by the Tukey test at 5% probability using the SISVAR program. The fruits of the plants treated with boscalid 75g ha-1 were the ones that showed higher concentration of soluble solids and low titratable acidity, resulting in a better ratio. Despite the lower value, the fruits of the plants treated with pyraclostrobin 50g ha-1 showed a high ratio value, besides presenting higher value for pulp texture. The mixture of boscalid (37.5g ha-1) + pyraclostrobin (25g ha-1) also showed high values of soluble solids which resulted in a good “ratio” value.

Silicon (Si) is a mineral element that provides many benefits to plants and may also assist in tolerance to abiotic stresses such as salinity. The aim of the study was to evaluate the use of Si as a possible attenuator of the deleterious effects of salinity on growth and post-harvest of lettuce. A completely randomized design with four replicates was performed in a 3 × 2 factorial, consisting of three salinity levels (1.65, 3.65, 7.65 dS m-1) and two levels of silicon (0.0 and 2.0 mM). Salinity reduced all variables related to plant growth. For shoot fresh and dry mass, it was observed that NaCl caused a reduction of 79.80 and 80%, respectively, in comparison to the control. However, parameters related to post-harvest such as titratable acidity, soluble solids and vitamin C increased with salinity. Although not effective in reducing saline stress on plant growth, Si provided improvements in the variables related to lettuce post-harvest. Salinity significantly reduced plant growth in the presence and absence of Si, but provided better post-harvest quality with Si.

Marolo is a fruit typical of the Brazilian Savanna that is highly appreciated for its exotic flavour, nutritional value and sensory attributes. This study aimed to assess the quality of fresh-cut marolo by checking for possible changes in physical, chemical, microbiological and sensorial characteristics during cold storage (12 days at 0°C, 5°C and 10°C). Firmness varied based on storage time; the fruit softened on the 8th day and then increased in hardness until the end of the study. The lowest storage temperatures reduced the darkening rate of this product. No variations in the levels of soluble solids (12.7 to 14.6°B) or total phenolics (741.06 to 1295.21 mg. GAE.100g-1) were observed. Fruits stored at 10 °C showed an increase in titratable acidity after the 5th day and an increase in pH on the 10th and 12th days. Increases in the soluble pectin (156 to 265.73 mg.100g-1) and total pectins (>1.000 mg.100g-1) were noted. No significant difference was observed in the count of the total and thermotolerant coliforms, and the growth of filamentous fungi and yeasts decreased after storage at 0°C and 5°C after the 5th day. Storage at 5 °C for 5 days was found to be the most efficient set of conditions for maintaining the physical, chemical, microbiological and sensory characteristics of marolo.

Abstract Ionizing radiation can be used for different purposes in the food industry. In this study, the effect of irradiation doses (0, 0.5, 1.0 and 1.5 kGy) on the quality parameters of long life tomatoes (Lycopersicon esculentum Mill.), was evaluated during 4 storage periods (1, 7, 14 and 21 days). The different treatments were evaluated by analysing for colour, pH, total soluble solids (TSS), total titratable acidity (TTA), ratio (TSS/TTA), hardness, total lycopene and ascorbic acid contents, weight loss and maturation stage (O2 /CO2 ratio) for all the storage periods. The tomato samples were irradiated in a Co60 irradiator and maintained at 22 °C ± 1 °C. The quality of the tomato fruits was influenced by the gamma radiation basically by making the fruits softer and not degrading the ascorbic acid and lycopene contents at the doses evaluated. The irradiation process used in the doses evaluated was promising with respect to maintaining the quality parameters of long life tomatoes.
