Effect of addition of Opuntia ficus-indica mucilage on the biological leavening, physical, nutritional, antioxidant and sensory aspects of bread
2019
The addition of active compounds to enhance the functional properties of foods is a quite common practice. Recently, bread became one of the target foods to incorporate functional ingredients such as those deriving from Opuntia spp. So far, only Opuntia ficus-indica cladodes in powder has been tested. The addition of fresh O. ficus-indica mucilage (in substitution to water) did not influence the biological leavening of the doughs. The resulting breads showed a biological role of the cactus mucilage, because their antioxidant activity was higher than that of control wheat bread. The sensory analysis indicated a general appreciation of the breads enriched with O. ficus-indica mucilage by the …
Influence of salt of different origin on the microbiological characteristics, histamine generation and volatile profile of salted anchovies (Engrauli…
2018
Abstract The effect of six salts of different geographical areas on the quality of salted anchovies was evaluated. The crude salts were chemically characterized by determination of inorganic and volatile organic compounds (VOCs). Salted anchovies, corresponding to six experimental trials, were subjected to microbiological, chemical (including histamine content) and sensory analysis during the entire period of ripening (150 days). The salts were characterized by marked differences in terms of major cations and trace element amounts. Among the 27 VOCs detected, octadecane was the most abundant compound and the main differences of the salts were registered for alkanes and alcohols. During matu…
Effects of 1-Methylcyclopropene on postharvest quality traits, antioxidant activity and ascorbic acid content of mature-ripe mango fruits
2017
Introduction - Mango (Mangifera indica L.) is a climacteric fruit, very sensitive to prolonged storage with a relatively short postharvest life. The aim of this study was to investigate the effects of 1-MCP treatment on the pomological and sensory traits, antioxidant capacity and ascorbic acid content in late ripening mature-ripe mango fruits submitted to a simulated shelf life at 20 degrees C. Materials and methods - Mango late ripening fruits (cv. Keitt) were harvested from a commercial orchard, located at Furiano, province of Messina (Sicily, Italy; 38 degrees 3'N, 14 degrees 33'E; 5 m a.s.l.). Fruits were treated with 1-MCP (0.005 kg m(-3)) for 20 h in 1 m(3) closed containers and then …
Fruit Quality Traits of Six Ancient Apple (Malus domesticaBorkh) Cultivars Grown in the Mediterranean Area
2015
ABSTRACTToday, ancient cultivars have been considered obsolete and replaced, leading to a dramatic loss of genetic diversity. In this trial we examined the quality of the six ancient apple cultivars: Bommino, Gelato, Miliadeci, Rotolari, Turco, and Virchiata. Fruit was submitted to the determination of physicochemical traits and a sensory profile was defined by a trained panel using 20 attributes. We also detected biometric data using a specific descriptor list. Obtained data showed interesting physicochemical and sensory traits among the observed cultivars. ‘Rotolari’, ‘Bommino’, and ‘Gelato’ should be used in breeding programs and revaluated for a placement on specific local markets.
Influence of Patagonian Lactiplantibacillus plantarum and Oenococcus oeni strains on sensory perception of Pinot Noir wine after malolactic fermentat…
2020
[Background and Aims]: The aim of this work was to study the effect of two Patagonian malolactic starters, Oenococcus oeni UNQOe 73.2 and Lactiplantibacillus plantarum UNQLp 11, on the wine composition and sensory perception after MLF of Pinot Noir wine.
Pomegranate Cultivation in Mediterranean Climate: Plant Adaptation and Fruit Quality of ‘Mollar de Elche’ and ‘Wonderful’ Cultivars
2021
Two pomegranate cultivars, Mollar de Elche, native to Spain, and Wonderful, the most widely cultivated pomegranate variety in the world, were studied in a commercial orchard in Sicily, and their phenological behavior was compared. During the development of the fruit, their dimensional growth was monitored, and after harvest, physicochemical and sensory analyses were carried out to highlight the differences between fruit of the two cultivars. Results showed that Mollar de Elche fruit require less time from flowering to fruit maturity, resulting in an earlier harvest, which was due also to a higher relative growth rate of the fruit&rsquo
Innovative Alcoholic Drinks Obtained by Co-Fermenting Grape Must and Fruit Juice
2019
In this study, Cabernet Sauvignon and Chardonnay musts, and fruit juices from cherry, kiwi, peach, and strawberry were co-fermented with Saccharomyces cerevisiae EC1118 and Torulaspora delbrueckii UMY196 at two different proportions (80:20 (v/v) and 60:40 (v/v)). The most pleasant fruit-based drink was obtained with Cabernet Sauvignon must and kiwi juice in a proportion of 60:40 and fermented with T. delbrueckii. This beverage was produced in higher volume to simulate a scale-up, and the aromatic profile, sensory description, and consumer acceptability were determined. The most powerful odorants of the kiwi-based drink were ethyl octanoate, phenylethanal, ethyl hexanoate, vinyl-guaiacol, be…
Genetic analysis of organoleptic quality in fresh market tomato. 2. Mapping QTLs for sensory attributes
2001
The organoleptic quality of fresh market tomato can be described by a set of attributes, including fruit appearance, taste, aroma and texture. Sensory analysis is the most-valid method to study organoleptic characteristics, particularly aroma and texture. A range of 144 recombinant inbred lines of tomato derived from a cross between a cherry tomato line and a large-fruited line was evaluated by descriptive sensory profiling. Taste was analyzed through sweetness and sourness, and aroma was analyzed through the overall aroma intensity, together with candy, lemon, citrus-fruit and pharmaceutical aroma. Texture was characterized by firmness, meltiness, mealiness, juiciness and difficulty to swa…
Fruit quality evaluation of affirmed and local loquat (Eriobotrya japonicaLindl) cultivars using instrumental and sensory analyses
2016
Introduction. Fruit quality can be evaluated by combining instrumental and sensory analyses. These methodologies have been affirmed and tested on different fruit tree species, but loquat is still little known from this point of view. Materials and methods. In this trial, conducted in Palermo and Catania (Sicily, Italy), both instrumental and sensory analyses were carried out on fruit of 8 loquat affirmed cultivars (‘Golden Nugget’, ‘Peluche’) and local cultivars (‘Marceno’, ‘Sanfilippara’, ‘Nespolone di Trabia’, ‘Virticchiara’, ‘Bianco Dolce’ and ‘BRT20’) with the aim of assessing their quality traits. Results and discussion. The sensory results agreed quite well with the physicochemical da…
Anti-Transpirant effects on vine physiology, berry and wine composition of cv. Aglianico (Vitis vinifera L.) grown in South Italy
2019
In viticulture, global warming requires reconsideration of current production models. At the base of this need there are some emerging phenomena: modification of phenological phases
