“…There was significant effect of MAP on reducing softening flesh of 'Douradão' peaches from MA50 and MA60 treatments, the values of flesh firmness were higher to these fruits and were similar to that after harvest (fruits not submitted to cold storage). Similar tendency was obtained by Akbudak;Eris (2004) and Seyoung et al (1997) in their studies on MAP effects on reducing softening flesh of other peaches cultivars.…”

“…The high decay incidence might be due the lack of plastic package protection, besides high rates of weight loss might increase decay incidence. These results are supported by reports from others studies on MAP effects on reducing decay (ZOFOLI et al, 1998;AKBUDAK;ERIS, 2004). There were 6% rotten fruit from MA75 treatment, probably, the anoxia inside the packages induced to fruit fermentation.…”

“…After 28 days of cold storage, the fruits within the control treatment showed 8.2% weight loss while those peaches packed in LDPE films reached around 0.20% and no differences among MAP treatments were detected, confirming previous reports about the properties of the plastic packages on reducing water loss (LURIE, 1993;CHURCH;PARSONS, 1995;GIRARDI et al, 2002;AKBUDAK;ERIS, 2004). After additional 4 days ripening, the control presented approximately 15% weight loss, due to the transpiration process that caused an excessive water stress, contributing to shrinkage and drying of some fruits.…”

“…The SSC from MA30, MA50 and MA60 were similar to that fruits evaluated immediately after harvest. Studies (GIRARDI et al, 2002;AKBUDAK;ERIS, 2004) about cold storage of others peach and nectarine cultivars under MAP support the results obtained on this study with respect to retarding the fruit ripening; the authors mentioned slight changes of SSC during cold storage and higher levels on control fruits when compared to MAP treatments.…”

-'Douradão' peach is a perishable product and when cold stored is subject to chilling injury. The objective of the experiment was to evaluate the effect of modified atmosphere packaging (MAP) and cold storage on quality and storage life of these peaches. Fruits were packed in polypropylene (PP) trays and placed inside low density polyethylene (LDPE) bags (30, 50, 60, 75 µm thickness) with active modified atmosphere (10 kPa CO 2 + 1.5kPa O 2 , balance N 2 ). The control was made with peaches held in nonwrapped PP trays. Fruits were kept at 1 ± 1 °C and 90 ± 5% relative humidity (RH) for 28 days and CO 2 and O 2 within packages was monitored every two days. After 14, 21 and 28 days, samples were withdrawn from MAP and kept in air at 25 ± 1 °C and 90 ± 5% RH for ripening. On the day of removal from the cold storage and after 4 days, peaches were evaluated for weight loss, decay incidence, flesh firmness, woolliness incidence, soluble solids content (SSC), titratable acidity (TA) and juice content. The results showed that MAP had influence on reducing weight loss and prevented postharvest decay. MAP of 1-2 kPa O 2 and 3-6 kPa CO 2 at 1 ºC (from 50 and 60 µm LDPE films) were effective for keeping good quality of 'Douradão' peaches during 28 days of storage, the ripe fruits showed reduced incidence of woolliness, adequate juiciness and flesh firmness. Packages of 30 and 75 µm LDPE films were ineffective for reducing woolliness during cold storage. MAP fruits showed lower SSC and no relevant effect on TA. Control fruits did not present marketable conditions after 14 days of cold storage. Index terms: Prunus persica, LDPE, chilling injury, woolliness, storage life. USO DE ATMOSFERA MODIFICADA PARA ESTENDER O PERÍODO DE ESTOCAGEM DE PÊSSEGOS 'DOURADÃO'RESUMO -O pêssego 'Douradão' é um produto perecível e, quando armazenado sob refrigeração, está sujeito à injúria pelo frio. O objetivo deste trabalho foi avaliar o efeito da embalagem de atmosfera modificada (AM) na qualidade e na extensão da vida de estocagem destes pêssegos refrigerados. Os frutos foram acondicionados em bandejas de polipropileno (PP) e colocados dentro de sacos plásticos de polietileno de baixa densidade (PEBD) com espessuras de 30; 50; 60 e 75 µm e com modificação ativa da atmosfera (10 kPa CO 2 + 1.5 kPa O 2 , balance N 2 ). O tratamento controle foi feito com pêssegos acondicionados em bandejas de PP sem embalagem plástica. Os frutos foram mantidos em câmara a 1 ± 1 °C e 90 ± 5% de umidade relativa (UR) por 28 dias, e as concentrações de CO 2 e O 2 dentro das embalagens foram avaliadas a cada dois dias. Após 14; 21 e 28 dias, as embalagens plásticas foram retiradas, e as amostras foram mantidas em ar a 25 ± 1 °C e 90 ± 5% UR para amadurecimento. No dia da remoção e após 4 dias, os pêssegos foram avaliados quanto a perda de massa, incidência de podridão, firmeza da polpa, incidência de lanosidade, conteúdo de sólidos solúveis (CSS), acidez titulável (AT) e teor de suco. Os resultados mostraram que as embalagens de AM tiveram influência na red...

“…The juiciness and the mealiness presented high negative correlation (-0.95), the same way firmness and mealiness (-0.94), certainly the fruits with more woolly and dry texture released little amount of juice on chewing and required lower force in the bite. Akbudak and Eris (2004) studied physical, chemical and sensory changes in 'Flavorcrest' and storage period. Control treatment reached higher levels, probably MAP delayed fruit ripening.…”

The sensory, physical and chemical characteristics of 'Douradão' peaches cold stored in different modified atmosphere packaging (LDPE bags of 30, 50, 60, 75µm thickness) were studied. After 14, 21 and 28 days of cold storage (1 ± 1 ºC and 90 ± 5% RH), samples were withdrawn from MAP and kept during 4 days in ambient air for ripening. Descriptive terminology and sensory profile of the peaches were developed by methodology based on the Quantitative Descriptive Analysis (QDA). The assessors consensually defined the sensory descriptors, their respective reference materials and the descriptive evaluation ballot. Fourteen individuals were selected as judges based on their discrimination capacity and reproducibility. Seven descriptors were generated showing similarities and differences among the samples. The data were analysed by ANOVA, Tukey test and Principal Component Analysis (PCA). The atmospheres that developed inside the different packaging materials during cold storage differed significantly. The PCA showed that MA50 and MA60 treatments were more characterized by the fresh peach flavour, fresh appearance, juiciness and flesh firmness, and were effective for keeping good quality of 'Douradão' peaches during 28 d of cold storage. The Control and MA30 treatments were characterized by the mealiness, the MA75 treatment showed lower intensity for all attributes evaluated and they were ineffective to maintain good quality of the fruits during cold storage. Higher correlation coefficients (positive) were found between fresh appearance and flesh firmness (0.95), fresh appearance and juiciness (0.97), ratio and intensity of fresh peach smell (0.81), as well as higher correlation coefficients (negative) between Hue angle and intensity of yellow colour (-0.91), fresh appearance and mealiness (-0.92), juiciness and mealiness (-0.95), firmness and mealiness (-0.94).
