“…The Pearson correlation changes indicated that physiological modifications occurred in sweet cherry exposed to postharvest chitosan treatment during cold storage and shelf life period, with changes in MDA content and enzyme activities as CAT, SOD, APX, LOX, PPO and POD. These results are in agreement with previous studies on other commodities (Infante et al, 2008a;Cano-Salazar et al, 2013;Guerra and Casquero, 2009;Infante et al, 2008b;Pasquariello et al, 2013).…”

“…'RG' in CS had higher levels of TSS:TA than apples stored in CA. Untreated 'RG' apples in CS had higher levels of TSS:TA than treated apples (Table 2), so fruit quality expressed as TSS:TA value, which has been found to be more closely related to quality than acid content or TSS alone (Guerra and Casquero, 2009), would be higher in untreated than treated fruit. Significant differences were found in TSS:TA ratio between cultivars during storage, so TSS:TA was higher in 'RC' than in 'RG' (Tables 1 and 2), due to the higher TSS value in 'RC'.…”

Apple (Malus domestica Borkh) cultivars 'Reinette du Canada' (RC) and 'Reinette Grise du Canada' (RG) have been declared throughout the European Community as protected designation of origin (PDO) 'Manzana Reineta del Bierzo'. The aim of this research was to find out the influence of storage technique on quality of PDO apple cultivars 'RC' and 'RG', and to evaluate the absence of traditional post-harvest treatments in these high quality cultivars in order to reduce pesticide residues in fruit. Apples were kept in standard cold storage or in controlled atmosphere (CA). At harvest time and during storage, fruit from each treatment and storage technique was analysed to determine quality parameters as well as disorder incidence. CA storage has been useful to delay the maturity process of PDO apple cultivars 'RC' and 'RG' and to reduce the incidence of storage disorders. Apple cultivars had different behaviour so 'RG' cultivar showed lower weight loss (5.1%), shrivelling (6.4%) and bitter-pit (11%) than 'RC' cultivar (8.3%, 60.8% and 34%, respectively) at the end of storage. The response of both cultivars to the treatment was quite different, so 'RG' adapted better than 'RC' to the absence of postharvest treatments. Untreated 'RG' showed more brightness, total soluble solids (TSS) and TSS:titratable acidity values than treated 'RG', factors that could improve consumer acceptance. Effectiveness of postharvest treatment in terms of bitter-pit was lower in 'RG' than in 'RC'. These results indicate that 'RG' would adapt better to storage without the use of chemical postharvest treatments.Additional key words: cold storage, controlled atmosphere, Malus domestica, postharvest treatment, storability. ResumenComportamiento en conservación de cultivares de manzana 'Reineta del Canadá'Los cultivares de manzana (Malus domestica Borkh) 'Reineta del Canadá' (RC) y 'Reineta Gris del Canadá' (RG) han sido declarados en la Unión Europea como Denominación de Origen Protegida (DOP) 'Manzana Reineta del Bierzo'. El objetivo de este trabajo fue averiguar la influencia de la técnica de conservación en la calidad de los cultivares de la DOP 'Manzana Reineta del Bierzo', 'RC' y 'RG', así como evaluar la ausencia de los tradicionales tratamientos postcosecha en estos cultivares de alta calidad con objeto de reducir los residuos finales en el fruto. Las manzanas fueron almacenadas en frío normal o en atmósfera controlada. En recolección y durante la conservación frigorífica se determinaron los parámetros de calidad y la incidencia de enfermedades. La técnica de atmósfera controlada fue útil para retrasar la maduración de los cultivares DOP 'Manzana Reineta del Bierzo' 'RC' and 'RG' y para reducir la incidencia de alteraciones durante conservación. Los cultivares tuvieron diferente comportamiento, de manera que 'RG' mostró menor pérdida de peso (5,1%), arrugamiento (6,4%) y bitter-pit (11%) que 'RC' (8,3%, 60,8% y 34%, respectivamente) al final de la conservación. La respuesta de los cultivares ante el tratamiento fue diferente, pues '...

“…, 2004), both TSS and TA would play an important role in the quality of this low‐sugar cultivar. High correlation has been found between TSS:TA and sensory characteristics in European plums (Guerra & Casquero, 2009). Moreover, it has been proved that consumer acceptance is governed by the sugar‐acid ratio (Crisosto et al.…”

European plum (Prunus domestica L.) cv. 'Oullins Gage' was harvested according to firmness on five harvest dates. Fruit was analysed at harvest and during storage for weight loss, firmness, total soluble solids (TSS), titratable acidity (TA) and skin colour before and after a 3-day shelf-life period at 20°C. Significant differences were found among harvest dates in fruit mass, skin colour, firmness, TSS and TA. Fruit mass, TSS and colour b* increased, whereas firmness and TA decreased significantly during the harvesting period. Firmness parameter as a maximum maturity index and TSS:TA (or b* colour, a non-destructive measurement) as a minimum maturity index could be used to distinguish maturity at harvest. It is suggested that the best post-storage quality of 'Oullins Gage' plums would be obtained when fruit is harvested with TSS:TA >9 or b* colour >30, but with a firmness >20N to assure a long storage life.
