Inhibition of Ulcerative Colitis in Mice after Oral Administration of a Polyphenol-Enriched Cocoa Extract Is Mediated by the Inhibition of STAT1 and …
2011
We studied a polyphenol-enriched cocoa extract (PCE) with epicatechin, procyanidin B2, catechin, and procyanidin B1 as the major phenolics for its anti-inflammatory properties against dextran sulfate sodium (DSS)-induced ulcerative colitis (UC) in mice. PCE reduced colon damage, with significant reductions in both the extent and the severity of the inflammation as well as in crypt damage and leukocyte infiltration in the mucosa. Analysis ex vivo showed clear decreases in the production of nitric oxide, cyclooxygenase-2, pSTAT-3, and pSTAT1α, with NF-κB p65 production being slightly reduced. Moreover, NF-κB activation was reduced in RAW 264.7 cells in vitro. In conclusion, the inhibitory eff…
Effects of adding solid and molten chocolate on the physicochemical, antioxidant, microbiological, and sensory properties of ewe's milk cheese.
2020
Abstract: A novel dairy product, namely “chocolate cheese”, was produced with two typical Sicilian food products: Pecorino cheese, processed from ewe's milk, and Modica chocolate. The cheese, manufactured with 0%, 5%, 10%, and 15% (w/w) solid or molten chocolate, was evaluated after 0, 2, 4, and 6 weeks of vacuum storage for its nutritional and health properties. The addition of chocolate reduced the pH, protein, fat, and ash; the addition of 5% or 10% molten chocolate reduced hardness (N/mm2). The addition of either solid or molten chocolate resulted in a slight increase (P < 0.1038) in the total polyphenol content, a higher oleic acid content, and less oxidative stability. The microbio…
Du vin au cacao : enjeux des sources et des méthodes pour une sémantique sensorielle
2018
Ce cours, proposé dans le cadre du séminaire du Professeur Eva Lavric à l’Université d’Innsbruck (Autriche), vise à discuter les enjeux, voire les défis, liés à une description linguistique, et surtout sémantique, du cacao. Ce faisant, il touche à la méthodologie d’une « linguistique sensorielle/de la sensorialité » dont il commence par présenter l’objet et la/les problématique(s), en particulier à travers la nécessité d’opter pour des paradigmes constructivistes de description du sens. Il s’arrête ensuite sur les acquis actuels dans la description de la langue du vin, en particulier de sa terminologie, en mettant en avant les manques de fondement théorique des roues des arômes, pourtant tr…
Validación funcional de extractos polifenólicos de cacao mediante ensayos in vivo con organismos modelo
2016
Los polifenoles son los principales antioxidantes de la dieta y a ellos se les atribuyen múltiples propiedades beneficiosas, como la prevención de enfermedades cardiovasculares, tumorales y degenerativas, que pueden aparecer como consecuencia del estrés oxidativo. El cacao representa una fuente interesante de polifenoles en la dieta, dado su amplio consumo y su riqueza en estos compuestos bioactivos. La actividad antioxidante de los polifenoles en general, y en concreto de los polifenoles del cacao, ha sido ampliamente evaluada in vitro. Sin embargo, los ensayos in vitro no tienen en cuenta aspectos fundamentales en organismos vivos como son la biodisponibilidad y metabolismo, ni proporcion…
The impact of chocolate on cardiovascular health
2011
Cardiovascular disease is the leading determinant of mortality and morbidity in women. Functional foods are attracting interest as potential regulators of the susceptibility to disease. Supported by epidemiological evidence, chocolate has emerged as a possible modulator of cardiovascular risk. Chocolate, or cocoa as the natural source, contains flavanols, a subclass of flavonoids. The latter years have witnessed an increasing number of experimental and clinical studies that suggest a protective effect of chocolate against atherogenesis. Oxidative stress, inflammation, and endothelial function define three biological mechanisms that have shown sensitivity to chocolate. Moreover, the consumpt…
