Storage of ‘Espada’ mango fruits in modified atmosphere and cooling: effects on conservation

Abstract

-Introduction. Brazil is a major producer of mangoes, but the export volume is still small because of the short shelf life of this fruit. The objectives of our work were to evaluate the effect of modifying the storage atmosphere using plastic film and temperature, according to different periods of storage, on the characteristics of Espada mango grown organically. Material and methods. Seven treatments were applied to the fruits after their harvest: fruits stored at room temperature; at 12°C / 80-90% relative humidity (RH); washed and stored at room temperature; washed and stored at 12°C / 80-90% RH; washed, packed in PVC and stored at room temperature; washed, packaged in PVC and stored at 12°C / 80-90% RH; and fruits harvested on the same day of evaluations, at (5, 9, 13, 16 and 21) days of storage. Results and discussion. Storage at 12°C and 80-90% RH was more efficient in delaying fruit ripening, with minor evolution of peel and pulp color and soluble solids contents; this treatment also delayed the development of anthracnose. Fruits packed in PVC and stored at room temperature kept the peel and pulp color for 13 days, compared with 9 days for non-packaged fruits. The ideal time to harvest the Espada variety occurs at 165 days after the onset of flowering, with an index of "3" for skin color (equal amounts of green and yellow) and pulp color (yellow pulp), and soluble solids of 8.5°Brix. The low severity of anthracnose found at different evaluation times indicates the probable tolerance of the Espada variety to the pathogen.Brazil / Mangifera indica / fruits / postharvest ripening / controlled atmosphere storage / keeping quality Stockage de mangues 'Espada' sous atmosphère modifiée et réfrigérée : effets sur la conservation des fruits.Résumé -Introduction. Le Brésil est un important producteur de mangues, mais le volume des exportations est encore faible en raison de la courte durée de conservation de ces fruits. L'objectif de notre travail a été d'évaluer, en fonction de différentes périodes de conservation, l'effet de la modification de l'atmosphère de stockage par utilisation d'un film plastique, ainsi que l'effet de la température de stockage, sur les caractéristiques de mangues Espada cultivées biologiquement. Matériel et méthodes. Sept traitements ont été appliqués aux fruits après leur récolte : fruits conservés à température ambiante ; à 12°C / 80-90 % d'humidité relative (HR) ; lavés et stockés à température ambiante ; lavés et stockés à 12°C / 80-90 % HR ; lavés, emballés sous PVC et conservés à température ambiante; lavés, emballés et stockés sous PVC à 12°C / 80-90 % HR; fruits récoltés à la même date que les évaluations effectuées après (5, 9, 13, 16 et 21) jours de stockage pour les six autres traitements. Résultats et discussion. Le stockage à 12°C / 80-90 % HR a été le plus efficace pour retarder le mûrissement des fruits, avec une évolution mineure des couleurs de peau et de pulpe et des teneurs en solides solubles ; ce traitement a aussi retardé le développement de l'anthracnose.

Quality Changes in Fresh Mango Fruits (<i>Mangifera indica</i> L. ‘Nam Dok Mai’) Under Actual Distribution Temperature Profile from Thailand to Japan

“…To date, studies to store mangoes have only been performed at a constant temperature (Medlicott et al, 1990;Ueda et al, 2001;Galli et al, 2013). However, it is not always possible to maintain a constant temperature throughout the actual distribution process.…”

Effects of innovative packaging materials on apricot fruits (cv Tom Cot®)

“…Recently, a commercial multilayer film used for MAP performed well in maintaining the quality for the cold storage period for up to 20 days in old Italian plum cultivars [15]. The use of PVC to store mango fruits at room temperature allowed the skin and pulp colour to be maintained for 13 days, compared with 9 days for unpackaged fruits [16].…”

EFEITO DA TEMPERATURA E DE EMBALAGENS SOBRE A ANTRACNOSE EM FRUTOS DE MANGA cv. TOMMY ATKINS

“…Palmer, dentre as temperaturas, 10ºC foi a que demonstrou menores médias para todas as embalagens analisadas. Galli et al (2013) observaram que o armazenamento a 12°C para mangas cv. Espada foi o mais eficiente para o controle do desenvolvimento de C. gloesporioides, diminuindo a severidade da doença, e consequentemente, controlando-a.…”
