Consumer Acceptance and Quality Parameters of the Commercial Olive Oils Manufactured with Cultivars Grown in Galicia (NW Spain)

2020

Mansa and Brava are olive autochthonous cultivars from Galicia, a new olive-growing zone from NW Spanish, from which high-quality extra virgin olive oils (EVOOs) are obtained. The oils obtained as by co-crushing Mansa and Brava olives in different proportions as by blending with others olives cultivars have different composition that influence in their sensory quality. The consumer acceptance of commercial oils elaborated with Local Galician cultivars was evaluated and a quality-mapping of olive oils was created. It was found that the both Local oils had good physical-chemical quality parameters. From sensory analysis viewpoint, Local-MB oils presented the highest intensity values for color…

Pomological, Sensorial, Nutritional and Nutraceutical Profile of Seven Cultivars of Cherimoya (Annona cherimola Mill)

2020

In this work, the food quality of four international (Campas, Chaffey, Fino de Jete and White) and three local (Daniela, Torre1 and Torre2) cultivars of Cherimoya (Annona cherimola Mill) was investigated. With this aim, pomological traits, sensorial attributes, physiochemical parameters (pH, total soluble content and total acidity), nutritional composition (macro- and micro-nutrients) and nutraceutical values (bioactive compounds, radical scavenging and antioxidant properties) were evaluated. Among the seven observed cultivars, Fino de Jete was identified as the best, not only for its commercial attributes such as pomological traits and physiochemical values, but also for its nutritional co…

A comparative analysis of genetic variation in rootstocks and scions of old olive trees – a window into the history of olive cultivation practices an…

2014

Background Past clonal propagation of olive trees is intimately linked to grafting. However, evidence on grafting in ancient trees is scarce, and not much is known about the source of plant material used for rootstocks. Here, the Simple Sequence Repeat (SSR) marker technique was used to study genetic diversity of rootstocks and scions in ancient olive trees from the Levant and its implications for past cultivation of olives. Leaf samples were collected from tree canopies (scions) and shoots growing from the trunk base (suckers). A total of 310 trees were sampled in 32 groves and analyzed with 14 SSR markers. Results In 82.7% of the trees in which both scion and suckers could be genotyped, t…

The aroma of strawberry (Fragaria ananassa): Characterisation of some cultivars and influence of freezing

1990

The volatiles of six strawberry (Fragaria ananassa Duch) cultivars, both fresh and deep-frozen, were isolated by direct dichloromethane extraction. Sixty compounds were identified and quantified by GC—MS. Characterisation of cultivars was achieved by applying principal component analysis to the chromatographic data. Great differences were observed. Maxim and Directeur Paul Wallbaum are rather low in volatiles while Gariguette and Tioga are rich in mesifurane (2,5-dimethyl-4-methoxy-2,3-dihydrofuran-3-one), furaneol' (2,5-dimethyl-4-hydroxy-2,3-dihydrofuran-3-one) and nerolidol. Esters are the major compounds in Senga Sengana and Vicomtesse Hericart de Thury. This last cultivar is also chara…

Evaluation of strawberry cultivars in soilless cultivation in Sicily

Effects of plant type on two strawberry cultivars in Sicily

2014

In Sicily fresh plants have for years been replacing the once popular cold-stored ones. Good early cropping is the aim of all strawberry growers in the island’s Marsala district. The present trial tested the response of the new strawberry cultivars ‘Sabrosa’ and ‘Florida Fortuna’ using fresh plug and bare-root plants. ‘Florida Fortuna’ plug-plants turned out to be the most promising type as a cash crop in delivering extra early ripening.

FRUIT QUALITY EVALUATION OF FOUR LOQUAT CULTIVARS GROWN IN SICILY

2011

Chemical (soluble solids content, titratable acidity, pH), morphological (weight, longitudinal and transversal diameter, thickness of the flesh, number of seeds, peel colour), and sensorial characteristics of four loquat cultivars (‘Algerie’, ‘Claudia’, ‘Nespolone di Trabia’ and ‘Sanfilippara’) from mature, organically-grown trees in Sicily, were analysed. The determinations were carried out by traditional instrumental techniques, by a panel test and by an electronic olfactory system. A panel of 10 trained judges was used to determine intensity of some attributes in the sensory profile of the different cultivars, while the electronic olfactory system was used to identify possible difference…

Study on New Strawberry Varieties Evaluated in Sicily

2009

The variety evolution and growing techniques have modified the strawberry cultivation in the Italian Mediterranean areas. Different trials in Sicily showed that varietal choices are the base to reach high levels of quality and quantity production. In Sicily, 300 ha of strawberries are now cultivated and 'Tudla' is still the principal variety (60%), 'Camarosa' is the most cultivated variety in the other southern strawberry areas, but in Sicily this cultivar does not generate a great interest because of its lateness. New cultivars, such as 'Candonga', 'Ventana' and 'Naiad', have been trialled in the last years but further evaluations are necessary. The trial was carried out at the experimenta…

Analysis of aroma compounds of nine autochthonous and non-autochthonous loquat cultivars grown in Sicily

2021

Loquat cultivation in Sicily is mainly based on nonnative cultivars and local ecotypes characterized by high nutraceutical value and appreciable physicochemical characteristics. Increased interest in commercial loquat production has increased the intention to provide premium quality loquat cultivars that include volatile substances capable of conditioning the sensorial properties and, therefore, the acceptability of fruits by consumers. This study determined the content of volatile compounds in nonnative and local loquat fruits grown in Sicily. Analyses were performed on five international cultivars and four local cultivars.
