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.
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…
FIRST STAGES OF MICROSPORE REPROGRAMMING TO EMBRYOGENESIS THROUGH ISOLATED MICROSPORE CULTURE IN Eriobotrya japonica LINDL.

Effects of Tray-Drying on the Physicochemical, Microbiological, Proximate, and Sensory Properties of White- and Red-Fleshed Loquat (Eriobotrya Japoni…
2022
Loquat fruits, highly valued by consumers for their characteristic aroma and pleasant taste, have a short post-harvest life and are susceptible to mechanical damage, loss of firmness, and initial organoleptic characteristics. The aim of this work was to develop a drying method suitable for storing loquat fruits in polyamide/polyethylene (PA/PE) bags containing two gaseous mixtures (treatments): MAPN2 (100% N2) and MAPP (21% O2 and 0.04% CO2), at room temperature (20 ± 1 °C) for at least 2 months. The effects of these conditions on the physico-chemical, microbiological, proximate, and sensory properties of fruit stored over a 50-day time interval were studied. The results showed that convect…
Effects of 1-MCP on post harvest quality and internal browning of white-flesh loquat fruit during cold storage
2017
Introduction – Treatments with 1-methylcyclopropene (1-MCP), an inhibitor of ethylene perception, were investigated on white-flesh loquat fruit to extend its shelf life and to prevent chilling injury. Ma- terials and methods – The loquat (Eriobotrya japonica Lindl.) white-flesh fruits (cv. Claudia) were submitted to applications of 1-MCP at 1 °C for 20 h and at concentrations from 1 to 5 μL L . The treated fruits were stored at 1 °C for 21 days before removal to 20 °C for ripening (shelf life). Fruit quality was analyzed at harvest, at the end of each storage period (7, 14, 21 days at 1 °C). Results and discussion - The 1-MCP treatment slowed fruit softening depending on concentration, and …
Use of Hanseniaspora uvarum and a novel strain of Saccharomyces cerevisiae isolated from manna ash to produce loquat beer

Heat requirements for loquat fruit development may be assessed with a Beta model approach
2018
In Mediterranean areas, loquat trees (Eriobotrya japonica Lindl.) typically bloom in fall and fruits develop during the winter period, reaching their ripening in spring. So far, little interest has been driven towards models capable of estimating heat requirements for the accomplishment of fruit development in the winter period. In this work, we verified whether in Mediterranean areas the heat accumulation (GDH) needed for loquat fruit growth, may be precisely described using a Beta model, a flexible mathematical function which, in the past, has been successfully used in peach. BBCH phenological stages of ‘Algerie’ trees were recorded in two experimental sites: Palermo, Italy (38°04’N, 13°2…
Gibberellic acid and flower bud development in loquat (Eriobotrya japonica Lindl.)
2011
The application of gibberellic acid (GA 3) to the whole loquat tree from mid-May to early June and from early August to the onset of flowering, significantly reduced the number of premature flowering shoots per current shoot and per m 3 of canopy, and so reduced the total number of panicles per m 3 of canopy. The number of vegetative shoots per m 3 of canopy was also significantly reduced by applying GA 3. The response depended on the concentration applied and produced optimal results at 50mgl -1. Differences in the number of flowers per panicle and leaves per shoot were not significantly modified by the treatment. Nevertheless, GA 3 applied directly to the developing apex near to flower di…
Influence of indigenous Hanseniaspora uvarum and Saccharomyces cerevisiae from sugar-rich substrates on the aromatic composition of loquat beer
2022
The demand for unique and exclusive food products and beverages is constantly on the increase. One of the products that mostly evolved to encounter market dynamics in the last decade is craft beer. For a long time, craft breweries have included fruit in beer production to enrich flavour and aroma profile of different beer styles. In this study, for the first time, the use of Saccharomyces and non-Saccharomyces yeast strains isolated from high -sugar matrices (manna and fermented honey by-products) were investigated to diversify fruit craft beer pro-duction, in order to improve the fermentation process and highlight the complexity of aroma profiles generated during alcoholic fermentation.
