  • Effects of cold storage on quality parameters and nutraceutical compounds
           of pomegranate fruits (cv. Acco)

    • Authors: Aurora Cirillo, Anna Magri, Milena Petriccione, Claudio Di Vaio
      Pages: 15 - 23
      Abstract: Punica granatum L. contains several bioactive compounds with antioxidant activity that have a positive effect on human health. This study aims to investigate the changes in the chemical-physical and qualitative parameters of pomegranate fruits cv. Acco from harvest up to +90 days of cold storage (+4°C and 95% RH). Morphological parameters, juice yield, weight loss, total soluble solids content (TSS), pH, titratable acidity, the color of the epicarp (L*, a*, b*), content of polyphenols, anthocyanins, flavonoids, and antioxidant activity were analyzed. The results showed an increase (about 29%) in the juice content (%) at +60 days of cold storage. Cold storage has also shown positive effects on some bioactive compounds. Flavonoids and anthocyanins content increase from 287.98 mg CE/100 ml of juice to 389.23 mg of CE/100 ml of juice and from 8.32 to mg/100 ml of juice to 11.13 mg/100 ml of juice at + 90 days of cold storage, respectively. On the basis of our results that confirmed the literature data, the pomegranate fruit is rich in bioactive compounds that exert beneficial actions on human health, and it has also been demonstrated that such nutraceutical compounds increased during cold storage, allowing the fruit to be preserved a long term.

  • Phytonutritional and aromatic profiles of Tulbaghia simmleri Beauv. edible
           flowers during cold storage

    • Authors: Ilaria Marchioni, Basma Najar, Andrea Copetta, Benedetta Ferri, Barbara Ruffoni, Luisa Pistelli, Laura Pistelli
      Pages: 25 - 32
      Abstract: Edible flowers are appreciated due to their aesthetic features, nutritional value and antioxidant properties. Tulbaghia simmleri Beauv. (Amaryllidaceae family) flowers are characterized by a pleasant garlic taste and are consumed both as fresh and dried products. The aim of this work was to assess the effect of chilling temperature (+4°C) on the visual quality, nutritional content, and aroma profile of T. simmleri flowers after two (T2) and six (T6) days of storage. Colorimetric analysis highlighted a reduction in petal brightness at T6 and hence their darkening, due to a significant increase in a* coordinate and decrease in the b* one. Total polyphenols and flavonoids content remained unchanged until the end of the experiment, while total anthocyanins increased at T2. Flowers antioxidant activity (DPPH assay) decreased progressively during cold storage, while catalase (CAT) and ascorbate peroxidase (APX) activities increased. The aroma profile was analyzed by HS-SPME associated with GC-MS, underlining that fresh flowers were dominated by high content in monoterpenes (around 80%), with 1,8-cineol as main compound (53.1%). Cold storage reduced this class of volatiles while sesquiterpenes and non-terpenes increased; between them, benzyl benzoate reached 12%.

  • Effect of microwave mild heat treatment on postharvest quality of table

    • Authors: Maria Lucia Valeria de Chiara, Nicola De Simone, Giuseppe Spano, Maria Luisa Amodio, Giancarlo Colelli
      Pages: 33 - 40
      Abstract: Table grapes are characterized by high susceptibility to mold development during post-harvest, mostly due to Botrytis cinerea. Microwave application on ready-to-eat product can represent an alternative to antifungal treatment. With the aim of identifying the maximum energy that can be applied on grape without detrimental effects a Central Composite Design was developed testing the application of 10 combinations of treatment time (seconds) and microwave power (Watt). As a result, energies above 8000 kJ negatively affected the sensorial quality of fresh product, both in the presence and absence of B. cinerea inoculum (106 log CFU g-1). The physico-chemical parameters did not show significant differences, but two time/power combinations improved sensory quality of table grape, being selected for the subsequent packaging trial: 14 s/100 W and 80 s/100 W. Treatments were applied before or after packaging in polypropylene bags. At the end of storage period, 100 W applied for 80 seconds before packaging led to a better external appearance of the product than the other treatments, maintaining an intermediate level of mesophilic bacterial load and no significant differences in terms of nutritional quality. 80 seconds at 100 Watt combined with packaging can represent a valuable starting point for further experiments.

  • Quality of cold stored lemon fruit from orchards consociated to ancient
           olive trees

    • Authors: Maria Allegra, Filippo Ferlito, Biagio Torrisi, Sara Trovato, Giuseppe Cicciarello, Maria Concetta Strano
      Pages: 41 - 48
      Abstract: In the hilly area of Gioia Tauro (Calabria, Southern Italy), lemon orchards are grown in consociation with centuries-old olive trees. Lemons are partially shaded by olive canopies and the microclimate at the level of their canopies is suitable for plants growth and quality productions. Under these conditions, lemon trees are grown even without irrigation, providing, despite this limitation, a quality product. This study aimed to i) investigate the qualitative characterisation of two clonal selections of the lemon cultivar Femminello, F. Siracusano (S) and F. Zagara bianca (ZB), from the described intercropping, on irrigated (I) and non-irrigated (NI) crops; ii) assess the quality preservation during cold storage, in order to evaluate the availability of lemons for marketing in a period of shortage such as the summer season. Fruits were harvested at commercial maturity, and cold stored at 10±1°C and RH 85-90%, for 60 days. Decay incidence, physiological disorders, weight loss, and the main physical-chemical parameters were assessed at harvest (T0) and every 15 days (T15, T30, T45, T60). The absence of decay and physiological disorders was observed throughout the 60-day storage period, in both clonal selections under the two management conditions. The weight loss was greater in fruits from irrigated lemon groves of both S and ZB. S_I showed significantly lower fruits weight and higher titratable acidity than S_NI. Total soluble solids and titratable acidity were statistically lower for ZB_I than for NI fruits.

  • Treated sediment as substrate component of three containerized ornamental
           species: effects on marketable and qualitative traits

    • Authors: Maria Castellani, Daniele Bonetti, Maurizio Antonetti, Domenico Prisa, Gianluca Burchi, Stefania Nin
      Pages: 49 - 57
      Abstract: Carried out within the LIFE17ENV/IT/000347-SUBSED project, this research aimed at investigating the effect of a treated sediment (TS) as substrate component on the quality and marketability of three widespread containerized ornamental species: cherry laurel (Prunus laurocerasus) cv. Novìta, calla lily (Zantedeschia aethiopica) and protea (Protea cynaroides) cv. Little Prince. The TS was mixed with soilless substrates as sphagnum peat, coir, and bark in different proportion (0%, 25% and 50%). In cherry laurel, the TS used in 25 - 50% proportions reduced plant height, slightly altering its attractive vibrant foliage. A positive effect of the TS was evidenced on calla lily, where both tested sediment-based mixtures allowed a copious blooming and flower quality raised as the sediment content increased (TS 50% > TS 25% > TS 0%). Post-harvest longevity and colour of flowers were not affected by substrate composition. The effect of sediment-based substrates on protea growth and blooming showed an opposite trend (TS 0% > TS 25% > TS 50%), with plants grown on 50% v/v TS exhibiting a considerable reduction in plant growth and production of flower clusters, with brighter tones turning towards purple. Based on sale values, the TS proved to be a sustainable alternative for the production of potted ornamentals if properly mixed with other organic matrixes, such as peat and coir.

  • Use of xanthan gum and calcium ascorbate to prolong cv. Butirra pear
           slices shelf life during storage

    • Authors: Eugenia Guccione, Alessio Allegra, Vittorio Farina, Paolo Inglese, Giuseppe Sortino
      Pages: 59 - 66
      Abstract: After cut, pear fruit (Pyrus communis L.) during shelf-life can be subjected to colour and flavour changes. To maintain flesh colour and firmness, different technologies could be employed during shelf-life, such as chemical, physical and edible coating treatments. In the present study, the effects of two edible coating formulations containing xanthan gum and calcium ascorbate on fresh-cut pear fruit were investigated. After harvest, 200 fruits were cut and coated with Xanthan Gum (XAN) and distilled water or Xanthan gum + Calcium Ascorbate (ASC), respectively, while control (CTR) pear fruit slices were soaked in distilled water and lastly packed in polyethylene terephthalate (PET) packages sealed with a composite film (PP-PET). All samples were stored at 5±0.5°C with RH 90% for 10 days. Measurements were carried out at 3, 5, 7 and 10 days of storage evaluating visual quality score, browning index, color, total solid soluble content (TSS), flavor, ascorbic acid content and total phenols content. The results showed that ASC treatment was the most efficient treatment in terms of color changes, ascorbic acid content, visual quality score and browning index, until the 7th day of storage. Moreover, ASC treatment reported lower mean values in terms of taste and flavour score if compared to CTR and XAN treatments. Untreated pear slices (CTR) kept good values concerning flavor score until the 3rd day of storage while on the 5th and 7th day off-flavour values were the same as treated samples.

  • CO2 modified atmosphere packaging: stress condition or treatment to
           preserve fruit and vegetable quality'

    • Authors: Maria Cefola, Imperatrice Capotorto, Vincenzo Lippolis, Salvatore Cervellieri, Anna Damascelli, Rosaria Cozzolino, Beatrice De Giulio, Bernardo Pace
      Pages: 67 - 73
      Abstract: In addition to the adoption of proper temperature and relative humidity, the selection of an atmosphere surrounding packaged fresh produce with reduced O2 and/or increased CO2 is one of the most widely used and useful tools to prolong the shelf-life of horticultural crops. However, as O2 and/or CO2 values that might cause injury are strictly related to the commodity, they should be optimized for each product. Here three study cases are reported about the application of modified atmospheres (MA), with different CO2 concentrations (0-40 kPa), to table grapes (cv. Italia) and sweet cherries (cv. Ferrovia) and, as short-term treatment (48 h at 0 °C), to fresh-cut artichokes (cv. Violet de Provence). In each trial, the effect of high CO2 treatment on quality parameters was observed during cold storage. Concerning table grape “Italia”, our results show that low CO2 (up to 10kPa) MA preserved the quality and sensory parameters of the fruit, whereas high CO2 (> 20 kPa) caused a fermentative metabolism. As for sweet cherries 'Ferrovia', 20 kPa CO2 MA helped to maintain the quality traits during storage. On the other hand, this fruit proved to be sensitive to CO2 accumulation (over 20kPa) in hypoxic conditions, since it caused an increase in respiration rate and the biosynthesis of volatile fermentative metabolites. Finally, for fresh-cut artichokes, a short-term CO2 treatment, up to 10kPa, reduced respiration rate and browning index, preserving the volatile profile, while high CO2 (40 kPa) may have caused fermentative metabolism. In conclusion, the application of a MA enriched in CO2 has been shown to have different effects on the quality parameters of the three products, in agreement with the fact that CO2 sensibility depends on each specific fruit or vegetable under study.

  • Non-destructive determination of ripening in melon fruit using
           time-resolved spectroscopy

    • Authors: Maristella Vanoli, Giovanna Cortellino, Valentina Picchi, Marina Buccheri, Maurizio Grassi, Fabio Lovati, Laura Marinoni, Pietro Levoni, Alessandro Torricelli, Lorenzo Spinelli
      Pages: 75 - 82
      Abstract: The aim of this work was to explore the feasibility of time-resolved reflectance spectroscopy (TRS) in determining the ripening degree and the quality of orange-fleshed melons. Sixty ‘Honey Moon’ melons were measured by TRS in the 540-1064 nm range and classified as less (LeM), medium (MeM), and more (MoM) mature according to increasing values of μa540. MoM fruit showed yellower peel color, slightly more orange pulp, higher juiciness and higher carotenoid contents than LeM ones. MoM fruit also showed higher internal ethylene concentration and lower firmness than LeM ones, even if the differences were not significant. The μa540 was positively related to internal ethylene, carotenoid accumulation, and juiciness, indicating that μa540 was linked to different ripening processes in melons. However, the relationship between μa540 and total carotenoid content was not as high as expected due to the low variability of pulp color and of carotenoid content. Changes in flesh color toward a more orange shade were accompanied by increased juiciness and ethylene production and by carotenoid accumulation, while changes in peel color were associated with changes in flesh firmness and juiciness. In conclusion, the absorption coefficient measured at 540 nm (μa540) by TRS could be used to sort melons in different ripening degrees; however, its applicability will need to be evaluated on a larger number of fruits and on other varieties.

  • Image analysis to predict the maturity index of strawberries

    • Authors: Antonia Corvino, Roberto Romaniello, Michela Palumbo, Ilde Ricci, Maria Cefola, Sergio Pelosi, Bernardo Pace
      Pages: 83 - 87
      Abstract: Traditionally, strawberries are harvested manually when the typical colour of the cultivar does not reach at least 80% of the surface. The focus of this research activity is to develop an automatic system based on image analysis in order to objectively define the optimal harvest time. Strawberries (cv. Sabrosa), with different degrees of maturation, were analyzed in four different harvesting periods and subsequently selected and classified, based on the ripening percentage, in three maturity classes: R0-25, R50-70 and R75-100. Each class of 10 strawberries, evaluated in triplicate, was subjected to image analysis and physiological and qualitative evaluation by measuring the following parameters: respiration rate, pH, total soluble solids content, and titratable acidity. The images captured, by a digital camera, were processed using Matlab® software and all the data found were supported by multivariate analysis. The image processing has made it possible to create an algorithm measuring objectively the percentage and the saturation level of red assigning the fruits to each class. Principal component analysis shows that discriminating parameters are the Chroma and the red Area, then used in a Partial Last Square Regression (PLSR) model to predict the TSS/TA ratio with R2 of 0.7 and 0.6 for calibration and validation set, respectively.

  • Transcriptional fermentation- and ethylene physiology-related genes
           expression profiles in Red Delicious apples stored under variable hypoxic
           conditions and protocols

    • Authors: Elige Salamé, Stefano Brizzolara, Marta Rodriguez, Matteo Iob, Pietro Tonutti, Benedetto Ruperti
      Pages: 89 - 99
      Abstract: Dynamic Controlled Atmosphere (DCA) is beneficial in maintaining specific quality parameters but, due to the extreme oxygen levels applied, can cause adverse effects on the fruit by inducing excessive anaerobic metabolism and the production of off-flavors. The metabolic adaptation and responses of apples (Malus domestica Borkh.) cv. Red Delicious to static or dynamic oxygen concentrations (0.3 and 0.8%, with sequential shifts) during cold storage for 7 months were studied by monitoring quality parameters and the expression of genes involved in sugar, fermentative metabolism, and ethylene physiology. Ethanol content reached the highest levels (around 400 mg/kg FW) under 0.3% oxygen concentration and fruit firmness appeared to be reduced in samples accumulating the highest levels of ethanol. Oxygen switch was effective in reducing the ethanol concentrations with timing-dependent variable effects. The expression of fermentative (alcohol dehydrogenase, lactate dehydrogenase, pyruvate decarboxylase) and sugar metabolism (β-amylase; phosphofructokinase; sucrose synthase) genes resulted to be differently affected by the hypoxic conditions imposed, in particular during the early stages of storage. Sucrose synthase expression appeared to be highly sensitive to changes in low oxygen concentration. Ethylene biosynthesis (ACC synthase and oxidase) genes showed marked differences in their expression in relation to the static and dynamic protocols and the hypoxic conditions, as well as six Ethylene Responsive Factors (ERF) genes, some of them possibly involved in the oxygen sensing mechanism operating in fruit tissues.

  • Application of antiperspirants to improve the condition of ornamental
           plants subject to medium- and long-distance transport in refrigerated

    • Authors: Lisetta Ghiselli, Daniele Bonetti, Domenico Prisa, Stefania Nin, Gianluca Burchi
      Pages: 101 - 109
      Abstract: The ornamental nursery sector sells and delivers its products not only within the European Union but throughout the world, thus shipping for long distances has become commonplace in the industry. Extended transport times may result in loss of quality and reduced longevity. Consequently, an effective logistics strategy is of competitive importance for nursery production. This research was carried out with the aim of improving long-distance transport conditions (up to 6 weeks) of ornamental plants produced in the nurseries of the Pistoia District. Phenotipic and physiological parameters of plants during transport were studied, testing three biodegradable antiperspirants and a biodegradable microfilm to protect plants on five important pot ornamental species: maple (Acer palmatum), cypress (Cupressocypari leylandii), privet (Ligustrum texanum), nandina (Nandina domestica) and viburnum (Viburnum tinus). Plant tolerance to storage conditions in refrigerated cell or container (T° = 8-12°C) varied considerably according to the considered species, with cypress resulting extremely tolerant and maple and nandina very sensitive. Treatments with antiperspirants did not exhibit particularly evident effects on the tested species. The use of biodegradable film was inadequate to protect plant quality during long-distance shipments. Even in cases of total or partial loss of leaves by species such as maple and nandina, an optimal recovery of vegetative development was highlighted once these species were relocated in outdoor cultivation. Among physiological parameters, MDA and phenols contents were the most stress-related variables, being negatively correlated to the quality decay of plants transported in dark refrigerated cells for 2-6 weeks.

  • Application of computer vision systems for assessing bergamot fruit
           external features

    • Authors: Souraya Benalia, Vittorio Calogero, Matteo Anello, Giuseppe Zimbalatti, Bruno Bernardi
      Pages: 111 - 116
      Abstract: Bergamot Citrus x bergamia Risso & Poiteau is an emblematic Citrus species of Reggio Calabria province (Southern Italy) where more than 90% of the global production thrives. The present work deals with the use of a non-destructive technique based on a computer vision systems to evaluate bergamot fruit peel colour, as well as dimensional features. To this purpose, experimental trials considered three bergamot cultivars, namely: ‘Femminello’, ‘Castagnaro’ and ‘Fantastico’. Bergamot fruit RGB images were taken using a laboratory inspection chamber equipped with a lighting system and a digital camera Nikon D5200 directly connected to a personal computer, to enable remote image acquisition. First, images were pre-processed according to a previously created colour profile. After that, bergamot fruit colour was analysed and expressed in terms of Hunter L, a, and b coordinates, which were used to calculate Standard Citrus Colour Index (CCI). In addition, dimensional features and shape descriptors were measured for each cultivar. Statistical data analysis, by applying the Kruskal-Wallis test at p<0.05 on CCI data highlighted significant differences between the assessed cultivars, and discriminant analysis (LDA) applied on CCI and dimensional features enabled a classification rate of 78.86% between cultivars, proving the reliability of computer vision techniques in assessing bergamot external features..

  • Sustaining low-impact practices in horticulture through non-destructive
           approach to provide more information on fresh produce history and quality:
           the SUS&LOW project

    • Authors: Marialuisa Amodio, Giovanni Attolico, Lucia Bonelli, Maria Cefola, Hassan Fazayeli, Francesco Montesano, Bernardo Pace, Michela Palumbo, Francesco Serio, Antonio Stasi, Giancarlo Colelli
      Pages: 123 - 132
      Abstract: The general aim of the project SUS&LOW is to increase the sustainability of fresh produce by testing and implementing low-input agricultural practices (LIP) with positive impact on product quality with the support of non-destructive (ND) tools for real-time quality assessment and for product discrimination. Additionally, new marketing strategies are generated to better support the added value of the products and to satisfy the final consumers’ preferences. The SUS&LOW project consists of three work packages (WP) and the adopted methodology used two model crops: rocket salad and tomato. The WP1, focused on the reduction of agricultural inputs, showed that sensor-based fertigation management might improve sustainability of soilless cultivation. Results coming from WP2, aimed to the evaluation of ND techniques, outlined the high potentiality of hyperspectral imaging (HSI) and Fourier transformed-near infrared (FT-NIR) techniques for the authentication of sustainable growing methods. Moreover, project activities’ proved computer vision system (CVS) as an effective tool for evaluating the product quality also through the bag. The WP3, dealing with marketing strategies, indicated a positive approach of consumers compared to LIP products certified through a visual storytelling platform.

  • Nanosponges and CPPU for shelf-life prolongation of cut carnations

    • Authors: Luca Battisti, Fabrizio Caldera, Gjylije Hoti, Francesco Trotta, Marco Devecchi
      Pages: 135 - 139
      Abstract: Nanosponges can favour the gradual release of molecules over a prolonged time, increasing the bioavailability and action of preservatives and phytoregulators, reducing the concentrations usually adopted. In floriculture, they have previously been proposed for the delivery of anti-ethylene compounds to improve the shelf-life of cut flowers. However, the potential of nanosponges is not only limited to these compounds. The present study evaluated the effects of β-cyclodextrin-based nanosponges and growth regulators on the post-harvest longevity of cut flowers of ornamental species. One novelty was the use of Forchlorfenuron (CPPU), a growth regulator belonging to the group of cytokinins predominantly used in fruit cultivation, to evaluate its potential to increase the shelf-life of cut carnations (Dhiantus caryophyllus). Specifically, as far as post-harvest longevity is concerned, the treatments involved the use of: deionised water; nanosponges and deionised water; nanosponges loaded with CPPU; nanosponges loaded with a classic solution for cut flowers, composed of sucrose, aluminium sulphate and 8-hydroxyquinoline sulphate. Preliminary results show that the nanosponge and deionised water complex and the nanosponge and classical solution complex prolonged the longevity of the cut flower by up to 20 days, compared to the control (17 days). In contrast, the CPPU-nanosponge complex showed similar results to the control. Replication of the research is necessary to validate the results.

  • Fruit maturity and antioxidant activity affecting superficial scald
           development in ‘Abate Fétel’ pears

    • Authors: Alessandro Bonora, Anna Venturoli, Melissa Venturi, Alexandra Boini, Luca Corelli Grappadelli
      Pages: 3 - 13
      Abstract: Superficial scald (SS) is one of the main physiological disorders affecting postharvest of pears. Its onset is linked to oxidative processes. Antioxidant compounds such as ascorbic acid and phenolics could play a key role in preventing SS. Growing environment and fruit quality also have an influence on SS symptoms occurrence. The aim of this project is to understand the relationship between antioxidant activity, phenolic content, and development of SS in ‘Abate Fétel’ pear. Moreover, the effect on SS of fruit maturity at harvest was assessed using multivariate statistical approach. Data were collected in thirty orchards in the Emilia-Romagna region (Italy) in three seasons (2018, 2019 and 2020), and the fruit were stored in a regular atmosphere for 120 days. Antioxidant capacity was determined by 2,2-diphenyl-1-picrylhydrazy (DPPH) method and total phenol content by Folin-Ciocalteau colorimetric protocol. The results showed that 340 mg of ascorbate/100 g of FW and 300 mg of gallic ac./100 g of FW at least provide good protection against SS. Multivariate analysis indicated that pulp firmness  and index of absorbance difference ( lAD ) seem to keep low the SS occurence, when at harvest are higher than 6.3 kg and 1.9, respesctively. In conclusion, it would be possible to build a forecasting model to control SS that considers pre-harvest data and content of antioxidants in different orchards, to improve the postharvest management of ‘Abate Fétel’.
