Simgi® platform as a tool for the study of wine active compounds in the  gastrointestinal tract

Abstract

Simgi® platform pursues the need for dynamic in vitro simulation of the human gastrointestinal tract optimized and adapted to food safety and health fields. The platform has confirmed the model’s suitability since its first’s studies with the consistency between the simulated colonic metabolism of wine polyphenols and the metabolic evolution observed with the intake of wine in human intervention studies [1]. 

Functioning under computer control of the physicochemical parameters, simgi® system is able to simulate separately or continuously the steps of gastric, intestinal digestion and colonic fermentation. In particular, this modular configuration has allowed the simulation of gastrointestinal digestions of red wine [1] or soluble grape extracts [2], and gastrointestinal survival of probiotic enological yeasts [3], as well as the evaluation of the food matrix effect when wine and its active compounds are ingested in combination with proteins, lipids or sugars. 

The physiological conditions of the ascending, transverse and descending regions of the colon are reproduced sequentially and include the human microbial intestinal community what makes able to study the interaction between gut microbiota and polyphenols. Part of simgi® simulation studies have been carried out with wine and winery by-products using healthy [2] and diabetic microbiota. Furthermore, the dynamic operation of simgi® system made it feasible to simulate a chronic intake (14 days) of a red grape pomace extract in combination with a probiotic strain of Lactobacillus plantarum, to assess the reciprocal benefits between polyphenols and probiotics on the growth and functionality of colonic microbiota [4]. Simgi® system is also an exclusive tool to carry out avant-garde products of interest in the wine industry, for example, antimicrobial silver nanoparticles [5] and microplastics which food safety is yet to be determined. Simgi® platform (www.cial.uam-csic.es/simgi/) proposes solutions to complex challenges to effectively support research and food industry development by acting as a complement and/or as a previous step to human studies, given their ethical and economic restrictions.

Using NIR/SWIR hyperspectral camera mounted on a UAV to assess grapevine water status in a variably irrigated vineyard

Vineyards face climate change, increasing temperatures, and drought affecting vine water status. Water deficit affects plant physiology and can ultimately decrease yield and grape quality when it is not well managed. Monitoring vine water status and irrigation can help growers better manage their vineyards.

Relation entre les caractéristiques des fromages d’Appellation d’Origine Contrôlée et les facteurs de production du lait

Les fromages d’Appellation d’Origine Contrôlée (AOC) représentent un enjeu économique important pour la filière laitière (11 % des fromages produits en France sont des fromages d’AOC, et dans certaines régions de montagne, cette proportion dépasse 50 %). Les spécificités de ces fromages et leurs liaisons avec les caractéristiques du terroir constituent un système complexe où interagissent en particulier la technologie fromagère et les caractéristiques des laits (composition chimique en particulier). Ces dernières dépendent elles-mêmes des caractéristiques des animaux (origine génétique, facteurs physiologiques, état sanitaire) et de leur mode de conduite (alimentation, hygiène, traite…) (fig. 1). L’influence de ces facteurs de production (alimentation et type d’animal en particulier) sur les caractéristiques des fromages est fréquemment mise en avant par les fromagers, sur la base d’observations empiriques. Il existe cependant très peu de travaux expérimentaux sur le sujet, en raison, entre autres, de la difficulté de séparer correctement les effets propres de ces facteurs d’amont de ceux liés à la technologie fromagère.

Does Dekkera/Brettanomyces wine spoilage raise the risk of biogenic amines intake? A screening in Portuguese red wines

Wine quality and safety are the main concerns of consumers and health agencies. Biogenic amines and polyamines, depending on their concentration and on individuals, in wine can constitute a potential public health concern due to their physiological and toxicological effects

Multivariate characterization of Italian monovarietal red wines using FTIR spectroscopy

The assessment of wine authenticity is of great importance for consumers, producers and regulatory agencies to guarantee the geographical origin of wines and grape variety as well. Since mid-infrared (MIR) spectroscopy with chemometrics represent a suitable tool to ascertain the wine composition, including features associated with the polyphenolic compounds, the aim of this study was to generate MIR spectra of red wines to be exploited for classification of red wines based on the relationship between grape variety and wine composition. Several multivariate data analyses were used, including Principal Component Analysis (PCA), Discriminant Analysis (DA), Support Vector Machine (SVM), and Soft Intelligent Modelling of Class Analogy (SIMCA).
