“…It can be seen that the total loss in weight did not exceed 2 % for all the samples including controls. This is less than that reported by Javanmardi and Kubota (26), who observed up to 5% weight loss after 7 days storage at room temperature (25-27 o C) for cluster tomatoes (cv. Clermon).…”

“…Furthermore, modification in the atmosphere can interfere in the synthesis of this pigment because it reduces the fruit metabolic activities resulting in lower ethylene production and decreased physiological changes (Fonseca et al, 2002). As the tomato ripening process is associated with increase in lycopene content (Javanmardi & Kubota, 2006), delay in this process can result in lower contents of this compound, as reported by Siripatrawan & Assatarakul (2009) when they used 32 μ commercial film associated with methyl jasmonate to store unripe tomatoes.…”

“…The fruit harvesting process generates stress and mechanical damage that results in cell signaling with the response of greater ethylene production (Ayub et al, 1995) that is accentuated when the fruits are depends on the ripeness stage and the development conditions of the fruits (Javanmardi & Kubota, 2006). Furthermore, modification in the atmosphere can interfere in the synthesis of this pigment because it reduces the fruit metabolic activities resulting in lower ethylene production and decreased physiological changes (Fonseca et al, 2002).…”

Quality of mini tomatoes harvested at two maturity stages and kept chilled in three packages

The economic importance of small tomato fruits has been increased considerably due to the significant levels of lycopene and sugars. However, to achieve these compounds, the harvest is limited to a ripening stage demanded by consumers, which could reduce this marked period. Harvesting at an early stage and use of conservation techniques are desirable to amplify the marketing period. The aim of this study was to evaluate the quality of small tomato fruits, Sweet Grape cultivar, harvested at two stages of ripening (light red and red), kept in three types of package (perforated PET, PEBD 30 μ and Vegetal Pack 18 μ) at a temperature of 20±1ºC and a relative humidity (RH) of 85±5% during 20 days. During this period, gas composition inside the packaging (O 2 , CO 2 and ethylene), peel color, fresh mass loss, soluble solids content (SS), titratable acidity (TA), SS/TA and ascorbic acid levels were evaluated every 5 days. The lycopene content was determined at the beginning and the end of conservation. The experimental design was completely randomized in a split plot with four replications. Mass loss, peel color and gas composition were affected by both stage of harvest and package. The total SS/TA increased 4.74 during the conservation for two stages, regardless of package. The light red fruits reached after 20 days of conservation, mean levels of lycopene of 16.47 mg 100 g -1 and SS/TA of 18.43; on the other hand the red fruits achieved 15.30 mg 100 g -1 of lycopene and 16.80 of SS/TA. There was a mean increase of 8.4 mg 100 g -1 of lycopene in light red fruits, while in red fruits, the increase was 0.9 mg 100 g -1 . The PEDB film was the best to maintain the fresh mass and peel color, therefore it was indicated for the maintenance of these attributes. The Vegetal Pack film showed no advantage in relation to the PET perforated packaging.

“…This result is consistent with studies that claim that the use of MA packages, when used properly, can reduce the weight loss (Rocha; Barreira; Morais, 2004). Weight loss in stored fresh fruits may occur due to water eliminated by transpiration (Javanmardi;Kubota, 2006) and metabolic respiration processes. Therefore, fruits stored in low water vapor permeable films tend to maintain the fresh weight longer.…”

The need for a permanent market supply of fresh fruit has generated great interest in postharvest techniques that can promote useful life and quality of the fruit. The aim of this study was to evaluate the efficiency of atmospheric modification using different polymeric films in maintaining postharvest quality and prolonging the shelf life of Eva (Mallus sp) apples. For this, fruits from the city of Barbacena -MG, selected and sanitized were packed in plastic trays and wrapped in the corresponding films. The films used were: polypropylene -20 µm, low-density polyethylene -14 µm and high-density polyethylene -7 µm. Another group of fruits (control) was not submitted to a modified atmosphere. Subsequently, all the the packages were stored under refrigeration (0 ° C ± 0.5) for 210 days and the evaluations of the following variables were performed every 30 days of storage: hydrogen potential (pH), titratable acidity, soluble solids, weight loss, firmness, total pectin, soluble pectin, pectin methyl esterase and polygalacturonase. The work was conducted in a completely randomized design (4x8), with 4 treatments and 8 experimental times. Each treatment consisted of three replicates and each experimental unit consisted of six fruits. The results were submitted to variance analysis and means were compared by the Tukey test at 5% probability and regression analysis. The low density polyethylene (14 µm) packaging provided the best conservation of the Eva cultivar apple textural characteristics. Index terms:Mallus sp, packaging, firmness, enzymes. RESUMOA necessidade de um abastecimento permanente do mercado com frutas frescas tem gerado um grande interesse em técnicas de conservação pós-colheita que possam promover a extensão da vida útil e da qualidade desses frutos. Objetivou-se, neste estudo, avaliar a eficiência da modificação atmosférica, utilizando diferentes filmes poliméricos na manutenção da qualidade pós-colheita e no prolongamento da vida útil de maçãs "Eva" (Mallus sp). Para tanto, frutos colhidos em Barbacena -MG, selecionados e sanitizados foram acondicionados em bandejas plásticas com seis frutos cada e estas, envoltas nos filmes correspondentes a cada tratamento. Foram utilizados filmes de polipropileno -20 µm, polietileno de baixa densidade -14 µm e polietileno de alta densidade -7 µm. Um outro grupo de frutos (controle) não foi submetido à atmosfera modificada. Feito isso, as embalagens foram armazenadas em câmara fria (0°C±0,5) por 210 dias e as avaliações foram realizadas a cada 30 dias de armazenamento, das seguintes variáveis: potencial hidrogeniônico (pH), acidez titulável, sólidos solúveis, perda de massa, firmeza, pectina total, pectina solúvel, pectinametilesterase e poligalacturonase. O trabalho foi conduzido em delineamento inteiramente casualizado (4x8), sendo 4 tratamentos e 8 tempos. Cada tratamento continha três repetições e cada unidade experimental foi constituída por seis frutos. Os resultados foram submetidos à análise de variância e as médias foram comparadas pelo teste de Tuke...
