Effect of Drying Condition on the Quality of Dry Late Peaches of Leonforte
2015
The Late Peach of Leonforte [Prunus persica (L.) Batsch] grown in Southern Italy matures in September and October and as late as November. Fruits are wrapped in paper bags to protect them from parasites and are harvested only when fully ripe. Protected inside the bags, they ripen late and take on a bright yellow colour with red streaks. Highly aromatic, the peach has yellow, firm flesh that is high in soluble solids and has a distinctive, slightly caramelized flavour. The aim of this work was to deter¬mine the best method of drying peach as a means of conserving the fruit after harvest due to its very limited shelf-life. Drying processes were carried out in a pilot plant utilising differen…
Chemical and acidic composition of Longissimus dorsi muscle of Comisana lambs fed with Trifolium subterraneum and Lolium multiflorum
2010
Aim of this study was to evaluate the effects of grazing on Trifolium subterraneum and Lolium multiflorum, as pure or associated crops, on the chemical composition and on the fatty acid profile of the intramuscular lipids of the meat of lambs. Forty Comisana male lambs, on average weighing 13.75±1.90 kg, were divided into four homogenous groups of ten and called, in relation to the diet: group T those grazing on T. subterraneum; Group L on L. multiflorum; Group TL on adjacent monocultures of T. subterraneum and L. multiflorum (66.6 and 33.3% of surface, respectively); Group LT on adjacent monocultures of T. subterraneum and L. multiflorum (33.3 and 66.6% of surface, respectively). Every 10 …
The quality of Valle del Belice sheep’s milk and cheese produced in the hot summer season in Sicily
2013
In response to the growing consumer demand for fresh cheese in summer, this investigation was aimed to evaluate the chemical and microbiological characteristics of sheep’s milk and cheese produced in Sicily in the hot summer months. A total of 810 bulk milk samples collected from 17 farms rearing ewes of the Valle del Belice breed were analysed for chemical composition, somatic cell count, total bacterial count and clotting parameters. Samples (n = 18) of Protected Designation of Origin Vastedda della valle del Belice cheese produced in six dairies were collected in summer, autumn and spring and analysed for chemical composition, microbiological profile and fatty acid (FA) composition. Univ…
Effects of gamma-irradiation on the alpha-tocopherol and fatty acids content of raw unpeeled almond kernels (Prunus dulcis)
2014
Abstract The present study evaluated fatty acid composition and α-tocopherol content of almond as a function of irradiation dose in order to determine dose levels causing minimal undesirable changes to almonds. Raw unpeeled almonds variety Tuono ( Prunus dulcis (Mill.) D. A. Webb) were irradiated using 60 Co source at dose of 0.5, 1.5, 3, 6, 8 and 10 kGy. Both control and irradiated samples were kept frozen and immediately analyzed. The data obtained showed no change in fatty acid compositions up to a dose of 10 kGy; on the contrary, a general trend observed is that increasing the dose of irradiation resulted in the decrease of α-tocopherol content. The study has shown that irradiation is a…
Fatty acid composition of the seed lipids ofChamaerops humilisL. natural populations and its relation with the environment
2014
Seed lipids composition is a tool to discriminate among plant taxa and is related to phylogeny and biogeographic distribution. Aim of the present study was to evaluate the fatty acid (FA) composition of the seed lipids from nine natural Chamaerops humilis L. population and its relation with the climatic traits of the collection sites. The average seed lipids content was 54.8 g kg21 and the most represented FAs were oleic (478 g kg21 oil) and linoleic (230 g kg21 oil), with significant differences among the accessions. Most of the lipid traits significantly correlated with climatic traits. In particular, oleic acid negatively correlated with year potential evapotranspiration. These relations…
Les enfants difficiles à table : conceptualisation et évolution
2022
L'objectif du présent article est de proposer un état des lieux des études récentes permettant d'offrir un cadre conceptuel et opérationnel au concept de comportement difficile à table, tout en mettant en lumière les conséquences psychologiques pour l'enfant, ainsi que les pratiques éducatives parentales associées. L'article ambitionne aussi de déterminer dans quelle mesure un enfant difficile est un mangeur à risque de développer ultérieurement des troubles du comportement alimentaire (anorexie mentale, ARFID), et quelles seraient les pistes à privilégier, en termes de guidance parentale, pour accompagner l'enfant.
Donner le choix du repas à l'hôpital : effets sur le gaspillage alimentaire et les représentations du patient
2018
International audience; L’hospitalisation survient comme étant une rupture dans la vie d’une personne. Projetée dans un environnement parfois inconnu, avec un rythme imposé par une organisation établie, les habitudes et rituels peuvent être bousculés lors de l’arrivée dans l’institution de santé. Le repas, qui représente une valeur forte dans notre société et un repère avec la vie précédant l’hospitalisation, est totalement redéfini. Il perd ses dimensions identitaire et commensale au profit des dimensions médicale et nutritionnelle. Les prises alimentaires peuvent alors diminuer, entrainer une diminution des apports énergétiques pouvant aller jusqu’à l’apparition d’une dénutrition. Le but …
Modificación del estilo de vida en el tratamiento de la obesidad y prevención del riesgo cardiometabólico mediante el uso de nuevas tecnologías
2018
Introducción: La obesidad, patología caracterizada por la acumulación de grasa y relacionada con un incremento del riesgo cardiovascular, se asocia con factores ambientales, genéticos y su interacción. Las estrategias terapéuticas actuales para el tratamiento de la obesidad se caracterizan por la modificación del estilo de vida, implementando estrategias de modificación conductual para la promoción de unas pautas dietéticas saludables y la realización de ejercicio. Actualmente nos encontramos en una sociedad digitalizada. Las nuevas tecnologías aplicadas al tratamiento de la obesidad son herramientas que pueden contribuir a la consecución de los objetivos establecidos. Objetivo: Estudiar si…
The hedgehog receptor patched is involved in cholesterol transport.
2011
International audience; BACKGROUND: Sonic hedgehog (Shh) signaling plays a crucial role in growth and patterning during embryonic development, and also in stem cell maintenance and tissue regeneration in adults. Aberrant Shh pathway activation is involved in the development of many tumors, and one of the most affected Shh signaling steps found in these tumors is the regulation of the signaling receptor Smoothened by the Shh receptor Patched. In the present work, we investigated Patched activity and the mechanism by which Patched inhibits Smoothened. METHODOLOGY/PRINCIPAL FINDINGS: Using the well-known Shh-responding cell line of mouse fibroblasts NIH 3T3, we first observed that enhancement …
