Hemp Flour Particle Size Affects the Quality and Nutritional Profile of the Enriched Functional Pasta
2023
The rheological and chemical quality of pasta samples, which were obtained using the durum wheat semolina fortified with the hemp seed solid residue, after oil extraction, sieved at 530 μm (Hemp 1) or 236 μm (Hemp 2) at different percentages of substitution (5%, 7.5%, and 10%, were evaluated. The total polyphenolic content in hemp flour was quantified in the range of 6.38–6.35 mg GAE/g, and free radical scavenging was included in the range from 3.94–3.75 mmol TEAC/100 g in Hemp 1 and Hemp 2, respectively. The phenolic profiles determined by UHPLC-ESI/QTOF-MS showed that cannabisin C, hydroxycinnamic and protocatechuic acids were the most abundant phenolic compounds in both…
Effect of different processing methods on the quality of obtained pomegranate juice
2019
Pomegranate juice has many health properties as the fruits contain anticarcinogenic, antimicrobial and antiviral compounds. Its consumption has greatly increased throughout the world in recent years due to the potential of its different components, polyphenols and anthocyanins mostly. Many studies have been performed on the pomegranate juice yield demonstrating its influence on the organoleptic and physicochemical properties of the juice. Commercial pomegranate juice production involves pressing the fruits. As a consequence, there is a need to investigate the pressing machine types and adjustment in order to maximize juice yield and enhance its health properties. The aim of this study was t…
Physicochemical, Nutraceutical and Sensory Traits of Six Papaya (Carica papaya L.) Cultivars Grown in Greenhouse Conditions in the Mediterranean Clim…
2020
Six papaya (Carica papaya L.) cultivars, grown in a Mediterranean climate under greenhouse conditions, were screened for physicochemical properties, antioxidant capacity, nutritional and sensory characteristics. The fruits, harvested with more than 50% of yellow surface (between 60% and 77%) were tested for carotenoids content, phenolic content, reducing activity (ABTS) and cellular antioxidant activity (CAA50). The physicochemical traits were measured in terms of the titratable acidity and soluble content whereas proximal composition along with moisture, fats, total sugar, ash, vitamin A, C and E content. Moreover, the sensory profile was analyzed by a semi-trained panel. Although the six …
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…
First Report of Phytophthora palmivora on Grevillea spp. in Italy.
2003
The genus Grevillea (family Proteaceae) comprises over 300 species and is a popular and widely cultivated group of Australian plants. In the last 3 years, numerous potted grevilleas with symptoms of decline associated with a rot of feeder roots were found in ornamental nurseries in Sicily. Aboveground symptoms were reduced growth, yellowing of foliage, wilt, dieback, and death of the entire plant. The disease was observed on many commercial cultivars and was especially severe on G. alpina (mountain grevillea), G. juniperina (juniper-leaf grevillea), G. lavandulacea (lavender grevillea), and G. rosmarinifolia (rosemary grevillea) as well as the hybrid cultivars Clearview David (G. lavandula…
Instrumental and sensory evaluation of eating quality of peaches and nectarines
2012
The influence of flesh firmness on consumer acceptance and its relationship with total soluble solids (TSS), titratable acidity (TTA) and sensory analysis were studied for fruits of ‘September Sun’ and ‘Sweet September’ (low acid) peach (Prunus persica (L.) Batsch), and ‘Maria Dolce’ (low acid) and ‘Venus’ nectarine (Prunus persica (L.) Batsch, var. nucipersica) cultivars. Sensory descriptors, assessed by a short-trained panel, were firmness, sweetness, sourness, aroma, acceptability. Different stages of fruit firmness did not always result in significant differences of TSS, TTA and their ratio, but the panel was able to discriminate fruit ripening stages, in terms of fruit firmness, aroma …
Race 1,2y of Fusarium oxysporum f. sp. melonis on Muskmelon in Sicily
2019
Muskmelon (Cucumis melo L.) is very important economically to agriculture in Italy. The Sicily area accounts for ≈40% of the total muskmelon production. Fusarium wilt caused by Fusarium oxysporum f. sp. melonis (Leach & Currence) W.C. Snyder & H.N. Hans. is the most prevalent and damaging disease of muskmelon in Sicily. Use of cultivars with major resistance genes, Fom 1 and Fom 2, is the most effective control measure for combating the disease. During March 1999, severe infections of Fusarium wilt were noted in a commercial muskmelon crop, cv. Firmo F1, grown in plastic tunnels in Syracuse Province (eastern Sicily). The muskmelon seedlings had been transplanted into the tunnels du…
Morpho-physiological variations in response to NaCl stress during vegetative and reproductive development of rice
2012
The complex nature of plant resistance to adverse environmental conditions, such as salinity and drought requires a better understanding of the stress-induced changes that may be involved in tolerance mechanisms. Here we investigate stress-related morpho-physiological effects during vegetative and reproductive growth in two Japonica rice cultivars (Bomba and Bahia) exposed to a range of NaCl concentrations from the seedling stage. The stress-related detrimental effects were observed either earlier or to a higher extent in cv. Bomba than in Bahia. Damages to the photosynthetic apparatus were related to loss of chlorophyll (Chl) and to a decrease of the maximum potential efficiency of PSII (F…
Wound-induced responses in leaves of strawberry cultivars differing in susceptibility to spider mite
2002
Summary The effect of leaf detachment and wounding on the activities of oxidative enzymes and ethylene production was studied in strawberry (Fragaria × ananassa) cultivars, differing in susceptibility to the spider mite (Tetranychus urticae Koch.). Strawberry plants were cultivated during winter in two growth conditions - with and without overwintering, in greenhouse and laboratory, respectively. Polyphenol oxidase activity, peroxidase activity and catalase activity in strawberry leaves depended on the cultivar analysed, type of treatment (detachment or detachment and wounding), as well as on plant growth conditions. Activities of all analysed enzymes were higher in control plants grown in …
