Dried-fruit shell reuse in green construction and building materials
2023
Bio-architecture is a new way of designing and building in line with the European Green Deal and in light of the circular economy principles. This new green approach is guiding the entire construction life cycle toward eco-sustainability and environmental friendliness, from the beginning to the end of the building process. In addition to the use of environmentally-friendly and high-performance building and construction materials, it is necessary to use new technologies that can reduce the environmental footprint. This paper aims to examine the possible reuse of biological wastes of agricultural origin of the Mediterranean basin, whose massive production generates a number of problems for th…
The Influence of Fruit Ripening Stage at Harvest and Storage Temperature on ‘Bianca di Bivona’ White Flesh Peaches
2015
‘Bianca di Bivona’ is a white-flesh peach cultivar, which ripens during the last week of July and the first of August. Its fruit are known because of their distinct flavor and aroma, which make them highly accepted, particularly in the local markets. However, nothing is known about their postharvest physiology and storage conditions. In order to investigate the effect of: (a) fruit ripening stage at harvest and, (b) storage temperatures, ‘Bianca di Bivona’ peaches were picked at mature-green, (60.0±1.3 N), and ripe stage (30.7 ± 2.1 N) determined by flesh firmness, and then stored at 0°C and 5°C (90% RH). Flesh firmness, total soluble solids, titratable acidity, weight loss and DA index, me…
Pulsed Electric Field Processing Optimization of Ascorbic Acid in a Mango and Papaya Beverage Sweetened with Stevia Rebaudiana
2016
During the processing of liquid foods, ascorbic acid may be altered, thus reducing beneficial health effects. For this reason, the degradation kinetics of ascorbic acid were determined in a fruit juice mixture (papaya and mango) sweetened with Stevia rebaudiana (SR) infusion after treatment by pulsed electric field (PEF) processing. The variable ranges were 20-40 kV/cm (electric field strength, E) during 100-360 μs (time treatment, t). The degradation equation was AA (mg/100 mL) = 26.842 - 0.101·E - 0.003·t- 10.371·%Stevia + 2.865·%Stevia2, demonstrating the use of PEF as an alternative to pasteurization treatments. However, results show the need to optimize treatment conditions whenever th…
Effects of 1-methylcyclopropene on postharvest quality of white- and yellow-flesh loquat (Eriobotrya japonicaLindl.) fruit
2014
Introduction. The effects of 1-methylcyclopropene (1-MCP) were evaluated on white-flesh cv. Claudia and yellow-flesh cv. Nespolone di Trabia loquat fruit. Materials and methods. Application of 1-MCP ((0.5 to 1) µL⋅L -1 for 20 h)) was monitored at 20 °C (7 days) and 0 °C (7 days at 0 °C and then 7 days at 20 °C). Results. Treatments with 1-MCP slowed fruit softening, depending on the concentration. Softening inhibition was greatest in fruit treated and held at 20 °C. The optimum concentration for softening inhibition at 20 °C was 1µ L ⋅L -1 of 1-MCP, while 0.5 µL⋅L -1 of 1-MCP was more effective at 0 °C. Conclusion. Treatments with 1-MCP inhibited titratable acidity loss in both cultivars. 1…
Insecticidal Activity of Strains of Bacillus thuringiensis on Larvae and Adults of Bactrocera oleae Gmelin (Dipt. Tephritidae)
1999
The olive fly, Bactrocera oleae, is the key pest on olives in the Mediterranean area. The pest can destroy, in some cases, up to 70% of the olive production. Its control relies mainly on chemical treatments, sometimes applied by aircraft over vast areas, with their subsequent ecological and toxicological side effects. Bacillus thuringiensis is a spore-forming soil bacterium which produces a protein crystal toxic to some insects, including the orders of Lepidoptera, Diptera, and Coleoptera and other invertebrates. The aim of this study was to search for isolates toxic to B. oleae. Several hundred B. thuringiensis isolates were obtained from olive groves and olive presses in different areas o…
Fruit Quality Traits of Two Apricot Cultivars
2010
In this trial we evaluated physical and chemical fruit quality traits and sensory profile of two late-ripening apricot cultivars ‘Vitillo’ and ‘Pellecchiella’. Fruits were harvested at full maturation in three different pickings, at 4 day intervals, to ensure the same fruit quality. To verify quality among different pickings, weight, diameter, soluble solid content, titratable acidity, pH, colour were recorded. To describe and quantify the sensory characteristics of apricot fruits a panel of 10 judges generated 16 descriptors. For each of these attributes judges assigned a score from 1 to 9. Qualitative and sensory data for each attribute were submitted to one way Analysis of Variance (ANOV…
Association of Marginal Leaf Scorch with Sodium Accumulation in Salt-stressed Peach
2000
The effect of specific ion toxicity during salt stress was tested in the present study. The experiment was repeated twice, in 1996 and 1998, with `Nemaguard' peach seedlings and rooted cuttings grown in hydroponics under two NaCl concentrations (50 and 30 mm). Foliage was separated in symptomatic and symptomless leaves and the amount of sodium (Na+) and chloride (C1–) was determined. Significantly higher Na+ content was found in symptomatic than in symptomless leaves in both experiments, whereas in only two of the six cases was Cl– content higher in symptomatic than in symptomless leaves. The Na+ threshold for leaf scorch was somewhere between 4 and 6 mg·g–1 dry weight. Results indicated th…
New low-vigour apricot rootstocks compared
2010
About ten years ago nurseries began to test several novel apricot stocks developed either to reduce plant vigour and boost early as well as high cropping or as a more suitable replacement for Myrabolan (Prunus cerasifera) and Apricot seedling in water-logged or chlorotic soils. These stocks were the Italian bred selections of Prunus domestica Penta and Tetra, the P. cerasifera Adara and the Prunus insititia Adesoto® 101, both Spanish-bred seedlings, and Plumina@, a Prunus bessey × P. cerasifera hybrid developed in France. Performance testing was carried out under a national project. The trials were set up in 2001 in plots of pilot orchards at Imola in Bologna Province, Ancona, Caserta, Pale…
Control of Bactrocera oleae and Ceratitis capitata in Organic Orchards: Use of Clays and Copper Products.
2010
Tests on the effect of clays (kaolin and bentonite) and copper products (hydroxide and oxychloride) in the control of olive fruit fly, Bactrocera oleae (Rossi), and Mediterranean fruit fly, Ceratitis capitata (Wiedemann), were carried out from 2003 to 2006 in olive groves and in organic citrus orchards (satsuma, clementine, ‘Navelina’ orange). Results demonstrate an efficacy of kaolin products in reducing attacks of B. oleae on olives and those of C. capitata on citrus fruits; in olive groves the clays gave similar or better results than copper hydroxide. Bentonite AG/8W showed a significant reduction in punctures by C. capitata. Bentonite products and BPLK kaolin are washed off by rainfall…
METABOLIC PROMOTERS AFFECT YIELD AND FRUIT QUALITY OF 'SANFILIPPARA' AND 'TRABIA' LOQUAT
2015
Preliminary field trials with foliar applications of phenylalanine, methionine, oxylipins and sugars have shown improvements of external color, sugar content and uniformity of maturation in grapes, pome fruits, tomatoes and melons. In this study, we hypothesized that similar improvements could be obtained both in fruit of âTrabiaâ and âSanfilipparaâ loquat (Eriobotrya japonica Lindl.) with applications of a commercial formulate called Sunred (Biolchim, Bologna, Italy) and containing various concentrations of the above metabolic promoters. The study was conducted on 12 âSanfilipparaâ and 12 âTrabiaâ adult loquat trees grown in an orchard near Palermo, Italy. Half of the trees…
