“…NEVES et al ( 2004) evaluated 'Golden Star' star fruit stored for 27 days at 12 °C, without modified atmosphere, and observed a reduction of 61% in fruit weight. CRUZ et al (2001), studying the effect of two packages in star fruit conservation, observed that fruit packed in LDPE 50 µm thick presented almost zero percentage of weight loss during storage at 10 °C. TEIXEIRA & DURIGAN (2006), observed 7.8% of loss in star fruit 'Fwang Tung' after nine days at 21 °C, the authors also reported no visible dehydration in the fruit.…”

“…When packed in 15 µm LDPE film, the fruit lost firmness, probably due to physiological disorders. In the study of CRUZ et al (2001), a proper conservation of Star fruit, stored at 12 °C, was achieved using LDPE 50 µm thick. Even though refrigeration and modified atmospheres have already been studied for fresh cut star fruit, little has been done considering the whole fruit.…”

Despite the fact that cold storage and modified atmosphere techniques have already been studied for fresh cut Star fruit, little has been done considering the whole fruit. Besides that, each cultivar has its peculiarities, so the efficiency of combined postharvest treatments should be studied. The objective of this study was to evaluate the effect of polyvinyl chloride (PVC), 8.5 µm thick and low-density polyethylene (LDPE), 33 µm thick associated with cold storage (10 ± 1 °C and 5 ± 1 °C / 85 ± 5% RH) on the conservation of ‘Malasia’ Star fruit. Storage at 25 oC maintained Star fruit overall quality, regardless of the film type, up to four days. The weight loss was higher in fruit packed with PVC, but this fact was not noticed by the sensory analysis. The storage in 5 and 10 oC did not caused chilling injury but fruit presented retention of yellow color development and firmness reduction; these aspects were positively assessed by the sensory analysis. The film type did not influence the conservation of the fruit. The storage at 5 and 10 °C, regardless of the package film, prolonged ‘Malasia’ star fruit shelf life up to 16 days, followed by two days at 25 °C.

“…The effects of that O 2 reduction and consequent increase of the of CO 2 content vary according to the exposure time and the barrier properties of the packaging material, but usually MA reduces the respiration rate and softening of the fruits, delays contamination by microorganisms, can inhibit the ethylene action besides maintaining the nutritional quality of the fruits for longer periods (Kader, 1993;Manolopoulou et al, 2010). High and low density polyethylene films and polypropylene films have been widely used for atmospheric modification of fruits and vegetables (Cruz et al, 2001;Donazzolo et al, 2003;Brackmann et al, 2006;Antmann;Lema;Lareo, 2008).…”

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...
