The potential of the Sorb (Sorbus domestica L.) as a minor fruit species in the Mediterranean areas: description and quality traits of underutilized accessions.
Biodiversity linked to fruit cultivation plays a key role in terms of the availability of quality products and nutraceutical compounds for the food industry. Thus underutilized species such as Sorbus domestica L. can be an important resource. The aim of this study was to evaluate 31 local accessions from different growing areas on the Island of Sicily and characterize the fruits according to the biometric-carpological features that constitute their quality in order to understand the potential that this species may have not only regarding the recovery and preservation of genetic resources in the Mediterranean area but also the nutraceutical compounds it offers. The results from this prelimin…
Effect of Palletized Map Storage on the Quality and Nutritional Compounds of the Japanese Plum cv. Angeleno (Prunus salicina Lindl.)
The influence of active modified atmosphere packaging MAP (10.0 kPa of O2 and 5 kPa of CO2) on palletized system was evaluated to extend the marketability of fresh plums cv. Angeleno. Fruits were wrapped with a polyethylene film in pallet bag units at 1C and 90% relative humidity for up to 60 days. The gas values of the pallet bags, the fruit weight losses and their qualitative and nutraceutical characteristics were periodically monitored to evaluate the goodness of storage. The results showed as the pallet bag have maintained the market life of Angeleno plums to up to 60 days, preserving the most important qualitative traits of fruits. After 20, 40 and 60 days the MAP treatment maintained …
ANTIOXIDANT COMPOUNDS AND QUALITATIVE TRAITS IN EUROPEAN (PRUNUS DOMESTICA L.) AND JAPANESE (P. TRIFLORA L.) PLUM FRUITS AS AFFECTED BY COLD STORAGE
The Italian territory is rich in fruit trees germplasm and in the last years many research programs have been carried out to characterize local cultivars and accessions for deepenings about them and enhancing the market agreement too. The Sicilian plum cultivars 'Sanacore' and 'Ariddo di core' and the Piedmontese plum cultivar 'Ramassin' were studied to highlight their qualitative traits including the nutraceutical properties. Moreover, since it is important to know in which way the qualitative parameters change during the storage period one more study was carried out by storing the fruits under modified atmosphere in the Tectrol ® system. The results evidenced very interesting aspects abou…
Pomological and quality traits of mulberry (Morus spp.) germplasm from Gorno Badakhshan in the Western Pamir
The local fruit biodiversity can represent a good opportunity to maintain the agriculture and to develop economies in "marginal" territory such as those in the mountain rural areas. The genetic diversity of the Morus spp. is little known in the Western Pamir mountains, so that the objective of the present study was to improve the knowledge of the polymorphism of the species in the different poorly explored Tajik valleys by investigating the main quantitative and qualitative traits. Materials and methods - Six selected sites of the Gorno Badakhshan Autonomous Oblast (GBAO) region were investigated through field measurement on morphological traits of mulberry trees (both from wild and cultiva…
Improvement of plum storage with modified atmosphere packaging
Post-harvest supply chain is a critical point for agro-food marketing. The management of freshness in the storage is fundamental to maintain high profits in the agro-food sector to improve the distribution and to respond to retailers and consumers' requirements. Plums are considered to have a climacteric-ripening pattern, in which ethylene is the hormone responsible for ripening. Modified atmosphere (MA) storage is a method helpful to maintain the natural quality of fruits. MA added to low temperatures influence fruit metabolism and reduce ethylene production, weight losses, hardness of pulp, preserving vitamins and organic acids. The objective of this study was to increase the condition of…
Quality of autochthonous Sicilian plums
Thirty four plum local varieties and accessions obtained from different growing area of the Sicilian island were analyzed for their qualitative and nutraceutical properties and three commercialcultivar were used as references. These properties included the fruit fresh weight (g), the pulp firmness (FFF), the total soluble solids (TSS), the titratable acidity (TA), the total anthocyanins,the phenolics content and the antioxidant activity.This preliminary study showed significantly differeces among the plums; Zuccarato giallo and Prunu Niuru presented TSS higher than the commercial cultivars (24.9 and 21.6 °Brix respectively)and interesting data obtained on the nutraceutical compounds values …
Evolution of qualitative characteristics during blueberry fruit storage in a modified atmosphere
The objective of this work was to evaluate the performance of different films to maintain MAP conditions for storing ‘Duke’ blueberries by verifying the evolution of qualitative traits of berries. The fruits were picked manually, individually deposited in polyethylene baskets and immediately transferred (1 h) to the laboratory under chilled conditions (10°C). The experimental storage units consisted of a pallet bag of two different types of film, polyethylene (100 μm) and a biobased film derived from starch (50 μm). The O2 and CO2 transmission rates, measured according to the ASTM F 2622-08 and ASTM F 2476-05 methods at 38°C and 90% RH, were, 2642 and 10654 [cm3/(m2·24 h)], respectively, fo…
Selection and micropropagation of valuable caper genotypes
The high quality of the various biotypes present in the natural or cultivated state is one of the main features for caper production. Up to now, however, no selection activity has been carried out in order to identify the most suitable accessions for providing better quality products. In this paper, we report the first results of a selection of caper genotypes characterised by significant qualitative traits. A micropropagation protocol was evaluated in order to improve and allow the multiplication of the most promising Capparis spinosa L. subsp. spinosa genotypes, selected in Salina (Aeolian Islands), Sicily (Italy), in collaboration with the most important local growers.
