Chemical–physical characteristics, polyphenolic content and total antioxidant activity of three Italian-grown pomegranate cultivars
2019
Background: In Mediterranean countries, there is an increasing demand for pomegranate fruits due to their antioxidant properties and nutritional values. The large diffusion of new genotypes and cultivars requires the knowledge of all fruit characteristics in connection with the cultivation area, to satisfy the market demand. This study seeks to determine the fruit quality attributes and nutraceutical values of three pomegranate cultivars (Wonderful, Acco and Kamel) grown in the Mediterranean climate. Methods: The fruits were evaluated for their main physico-chemical traits (weight, volume, height, width, thickness, total arils number, total arils weight, juiciness, fruit index, peel index a…
Pomological Traits, Sensory Profile and Nutraceutical Properties of Nine Cultivars of Loquat (Eriobotrya japonica Lindl.) Fruits Grown in Mediterrane…
2016
In this paper the diversity of fruit quality within nine loquat cultivars, including five international affirmed cultivars (Algerie, Golden Nugget, Peluche, Bueno, El Buenet) and four local cultivars (Sanfilippara, Nespolone di Trabia, BRT20 and Claudia), were investigated in order to discriminate the variation in pomological characteristics, sensory profile, and antioxidant properties. Finally, to evaluate potential bioactivity, antiproliferative activity of hydrophilic extracts from loquat fruits was assessed, at dietary relevant concentrations, against three human epithelial cell lines. Even though the international cultivars confirmed an appropriate level of commercial qualities in asso…
Consumer interest towards tropical fruit: factors affecting avocado fruit consumption in Italy
2017
Abstract The purpose of this paper is to identify the main factors affecting the consumption of avocado fruit among Italian consumers. In order to respond to the aim of the study, an empirical survey was conducted through the submission of an online questionnaire to 327 consumers. An ordered logit econometric model was adopted to examine the relationship among some explanatory variables and the frequency of consumption of avocado fruit. The findings of this study show that the consumption of avocado fruit is affected by different factors, including fruit consumption habit, neophilia attitudes, and various intrinsic and extrinsic quality attributes (credence attributes in particular). The st…
Identifying Host Molecular Features Strongly Linked With Responses to Huanglongbing Disease in Citrus Leaves
2018
© 2018 Balan, Ibáñez, Dandekar, Caruso and Martinelli. A bioinformatic analysis of previously published RNA-Seq studies on Huanglongbing (HLB) response and tolerance in leaf tissues was performed. The aim was to identify genes commonly modulated between studies and genes, pathways and gene set categories strongly associated with this devastating Citrus disease. Bioinformatic analysis of expression data of four datasets present in NCBI provided 46–68 million reads with an alignment percentage of 72.95–86.76%. Only 16 HLB-regulated genes were commonly identified between the three leaf datasets. Among them were key genes encoding proteins involved in cell wall modification such as CESA8, pecti…
The first high-density sequence characterized SNP-based linkage map of olive (Olea europaea L. subsp. europaea) developed using genotyping by sequenc…
2016
A number of linkage maps have been previously developed in olive; however, these are mostly composed of markers that have not been characterized at the sequence level, supplemented with smaller numbers of microsatellite markers. In this investigation, we sought to develop a saturated linkage mapping resource for olive composed entirely of sequence characterized markers. We employed genotyping by sequencing to develop a map of a F2 population derived from the selfing of the cultivar Koroneiki. The linkage map contained a total of 23 linkage groups comprised of 1,597 tagged SNP markers in 636 mapping bins spanning a genetic distance of 1189.7 cM. An additional 6,658 segregating SNPs were asso…
Pasta experience: Eating with the five senses - a pilot study
2018
Dried pasta is the Italian food “par excellence”. Traditional foods have characteristics that can stimulate or evoke in the consumer sensorial stimuli and experiences, especially when these foods are consumed in a typical-traditional restaurant. Traditional restaurants can use sensory marketing as a promotional advantage, creating a unique and original atmosphere that can represent their main way of differentiation. The aims of this paper are to know consumer liking with regard to two high quality types of Sicilian pasta, common dried pasta, and whole-wheat pasta, consumed in three different venues of a typical-traditional Italian franchised restaurant, and to measure the influence of envir…

Effetto del trattamento con 1-meticiclopropene su frutti di mango (Mangifera indica L.) della cul ti var Kei tt, conservati a temperatura ambiente
2016
Il Mango (Mangifera indica L.) è un frutto climaterico sensibile alle basse temperature e con una vita post-raccolta relativemente breve. L’obiettivo della ricerca è stato quello di valutare l’effetto dell’ 1-metilciclopropene (1-MCP), applicato a temperature ambiente, sulla conservazione di frutti di mango della cv Keitt. I frutti di Keitt, cultivar a maturazione tardiva, sono stati raccolti, presso un’azienda commerciale, sita a Furiano, in provincia di Messina (38°3' N, 14°33' E; 5 m s.l.m.). Immediatamente dopo la raccolta, sui frutti sono state effettuate le analisi chimico-fisiche: peso, consistenza, contenuto in solidi solubili, acidità titola- bile, colore, ecc. I frutti sono sta…
A New Bloody Pulp Selection of Myrobalan (Prunus cerasifera L.): Pomological Traits, Chemical Composition, and Nutraceutical Properties
2023
A new accession of myrobalan (Prunus cerasifera L.) from Sicily (Italy) was studied for the first time for its chemical and nutraceutical properties. A description of the main morphological and pomological traits was created as a tool for characterization for consumers. For this purpose, three different extracts of fresh myrobalan fruits were subjected to different analyses, including the evaluation of total phenol (TPC), flavonoid (TFC), and anthocyanin (TAC) contents. The extracts exhibited a TPC in the range 34.52–97.63 mg gallic acid equivalent (GAE)/100 g fresh weight (FW), a TFC of 0.23–0.96 mg quercetin equivalent (QE)/100 g FW, and a TAC of 20.24–55.33 cyanidine-3-…
Quantitative evaluation of the phenolic profile in fruits of six avocado (Persea americana) cultivars by ultra-high-performance liquid chromatography…
2016
The phenolic profiles of six varieties of avocado (Persea americana) grown in Sicily were investigated. The ultra-high-performance liquid chromatography-heated electrospray-mass spectrometry method was developed to determine qualitative and quantitative changes in fruits at two different ripening stage. Nineteen individual phenolic compounds were detected in avocado pulp extracts. Gallic acid, sinapinic acid, vanillin, p-coumaric acid, and gentisic acid were present only in ripe fruits. On the contrary, epicatechin decreased with fruit ripening, whereas protocatechuic acid, 4-hydroxybenzoic acid, chlorogenic acid, and benzoic acid were relatively stable or exhibited erratic changes with fru…
