Estabilidad de antocianinas durante el almacenamiento de jugos de arándanos
2016
Resumen: Antecedentes: Los arándanos y productos de arándano tienen alto valor nutricional, especialmente por su alto contenido de antocianinas. Estas son potentes antioxidantes y poseen alta capacidad de secuestrar radicales libres. Así, los arándanos y productos de arándanos han resultado atractivos para los consumidores interesados en alimentos funcionales. Sin embargo, los tratamientos térmicos y posterior almacenamiento de productos alimenticios influyen en el contenido de antocianinas. La cinética de degradación de las antocianinas puede ser evaluada desde una perspectiva termodinámica, basada en funciones como energía libre, entalpía, entropía y energía de activación. Objetivos: Se e…
Bresaola made from Cinisara cattle: effect of muscle type and animal category on physicochemical and sensory traits
2020
The physicochemical characteristics and sensory traits of Cinisara bresaola were investigated, to explore a new commercial opportunity for autochthonous dairy cattle farms. Semimembranosus, Semitendinosus and Biceps brachii muscles, from adult cows (AC) and grazing (GB) or housed (HB) young bulls of Cinisara breed, were processed to made bresaola. Differences due to animal category and muscle type were observed. Bresaola from AC was richer in fat and volatile organic compounds. The bresaola from Semitendinosus showed higher colorimetric parameters, fat and, when from grazing animals, Warner-Bratzler shear force than those made from other muscles. In general, all bresaola were well appreciat…
STUDY OF RASPBERRY EXTRACT APPLICATIONS AS TEXTILE COLORANT ON NATURAL FIBERS
2014
The present study deals with the biomordant assisted application of natural extracts obtained from red raspberry (Rubus idaeus L.) fruits onto two different cellulosic supports – flax and bamboo. The study relies on the improvement of multifunctionalities such as colour fastness, washing and rubbing fastness, due to the synergism provided by the co-assistance of both a biomordant, and the complex resulted by inclusion of the pigment molecule, in the cavity of MCT-β-CD; it is well known that natural dye molecule have a good selectivity binding to the hydrophobic monochloro-triazynil-cyclodextrin’s (MCT-β-CD) cavity to form inclusion complexes. An investigation system provided the characteriz…
Strengthening of Masonry Columns with BFRCM or with Steel Wires: An Experimental Study
2016
Nowadays, innovative materials are more frequently adopted for strengthening historical constructions and masonry structures. The target of these techniques is to improve the structural efficiency with retrofitting methods while having a reduced aesthetical impact. In particular, the use of basalt fiber together with a cementitious matrix emerges as a new technique. This kind of fiber is obtained by basalt rock without other components, and consequently it could be considered a natural material, compatible with masonry. Another innovative technique for strengthening masonry columns consists of applying steel wires in the correspondence of mortar joints. Both techniques have been recently pr…
Dietary polyphenols as antidiabetic agents: Advances and opportunities
2020
Abstract Dietary polyphenols have been widely investigated as antidiabetic agents in cell, animals, human study, and clinical trial. The number of publication (Indexed by Web of Science) on “polyphenols and diabetes” significantly increased since 2010. This review highlights the advances and opportunities of dietary polyphenols as antidiabetic agents. Dietary polyphenols prevent and manage Type 2 diabetes mellitus via the insulin‐dependent approaches, for instance, protection of pancreatic islet β‐cell, reduction of β‐cell apoptosis, promotion of β‐cell proliferation, attenuation of oxidative stress, activation of insulin signaling, and stimulation of pancreas to secrete insulin, as well as…
Interaction of dietary polyphenols and gut microbiota: Microbial metabolism of polyphenols, influence on the gut microbiota, and implications on host…
2020
Abstract The human gastrointestinal tract is inhabited by a vast number of microorganisms that are called as the microbiota. Each individual harbors a unique gut microbial composition, this composition evolves throughout the host's lifetime and it is easily affected by internal or external changes. It has been shown that gut microbiota plays a crucial role in host's health and as this complex community has the ability to interact with each other and with the host's immune system, the presence or absence of some major species can affect the homeostasis. Diet can be considered as one of the pivotal factors in modulating the functionality, integrity, and composition of the gut microbiota as th…
Dominant Lactic Acid Bacteria in Naturally Fermented Milks from Messinese Goat’s Breed
2019
Background: Lactic Acid Bacteria (LAB) are an important group of microorganisms responsible for the fermentation dairy products. This study was done to identify the dominant lactic acid bacteria in naturally fermented milks from Messinese goat’s breed. Methods: Eighteen individual raw milk samples collected from Messinese goat’s breed were acidified at pH 5.20 and left to spontaneously ferment at 37 °C for 4 days. All samples were analyzed for rod- and coccus-shaped LAB. Also, all presumptive LAB were isolated and differentiated according to their phenotypic properties and genetic polymorphisms and then identified by sequencing the 16S rRNA gene. Data were statistically analyzed using SAS 9…
SAMBHALA, HEAVEN CAN WAIT How 3D printing will sustain the future
2020
L’articolo, dedicato all’attività del gruppo WASP di cui Massimo Moretti è il fondatore, evidenzia come sia possibile conciliare l’avanzamento tecnologico con la creazione di un Paradiso in Terra: una società equa, ecocompatibile, scientificamente evoluta, totalmente open source. Questa non è utopia. È quello che sta accadendo grazie a progetti che rispondono concretamente ai bisogni fondamentali dell’uomo: Cibo, Rifugio, Salute, Energia, Lavoro, Cultura. Il caso WASP è indice di un cambiamento in atto. È un concentrato di tecnologia futuribile applicata in direzione sociale. È anche la dimostrazione lampante di come una visione etica sia praticabile all’interno di una logica aziendal…
De Bibracte à Augustodunum : permanences et évolutions des activités manufacturières de l’époque gauloise à la fin du Haut-Empire
2007
L’importance de l’artisanat autunois et son développement jusqu’au iiie siècle prennent racine à Bibracte qui a su exploiter les ressources naturelles de son environnement et parfaire un savoir-faire local ayant survécu à la conquête. Les recherches sur ces activités manufacturières menées conjointement à Bibracte et à Autun nous offrent ainsi une opportunité d’étudier ces problématiques sur la durée. À Bibracte, puis à Autun, les artisans du métal sont omniprésents, mais d’autres métiers, aux témoins plus discrets, ont pu aussi êtres identifiés. Dans le cadre de cet article, nous présentons succinctement les lieux de production et un bilan des différents corps de métier. Enfin, nous évoquo…
