These bacteria ferment fibre and increase the production of short-chain fatty acids (<a href=\"https:\/\/www.quironsalud.com\/es\/comunicacion\/actualidad\/acidos-grasos-cadena-corta\" target=\"_blank\" rel=\"noopener\">SCFAs<\/a>), which are key to colon health. These properties would make it possible to reuse residues from the juice extraction industry as functional ingredients, contributing to the valorisation of agricultural by-products.<\/p>\n<p>This is the main conclusion of a study carried out by researchers from the University of Lleida (UdL), Agrotecnio and the IRBLleida, published in the journal <em>Food Hydrocolloids for Health<\/em>. The study, entitled \u201cDesign of functional foods with active principles with potential anti-obesity properties\u201d, was led by the researchers Gemma Bell\u00ed, from IRBLleida-UdL, and Olga Mart\u00edn, from Agrotecnio-UdL, and forms part of the Agrohealth 2022 call, promoted by Agrotecnio and the IRBLleida.<\/p>\n<p>The study evaluated dietary fibre concentrates obtained from the bagasse (pulp and peel) remaining after the extraction of vegetable juices from artichoke, carrot, cucumber and red pepper, supplied by <a href=\"https:\/\/www.indulleida.com\/\" target=\"_blank\" rel=\"noopener\">Indulleida S.A.<\/a> The research team measured their impact on the specific composition of the intestinal microbiota and on SCFA production over 48 hours, using an <em>in vitro<\/em> digestion model that simulates the human gastrointestinal process.<\/p>\n<p>The results indicate that artichoke and carrot fibres especially stimulate beneficial bacteria such as <a href=\"https:\/\/en.wikipedia.org\/wiki\/Lactobacillus\" target=\"_blank\" rel=\"noopener\"><em>Lactobacillus<\/em> <\/a>and <a href=\"https:\/\/en.wikipedia.org\/wiki\/Bifidobacterium\" target=\"_blank\" rel=\"noopener\"><em>Bifidobacterium<\/em><\/a>. Artichoke fibre, moreover, generates the highest amount of butyrate or butyric acid, a compound that is essential as an energy source for colon cells and for maintaining the integrity of the epithelial barrier, with associated anti-inflammatory effects.<\/p>\n<p>Fermentations of cucumber, red pepper and carrot reach the highest concentrations of <a href=\"https:\/\/en.wikipedia.org\/wiki\/Acetic_acid\" target=\"_blank\" rel=\"noopener\">acetic acid<\/a>, which is involved in various physiological functions, such as the regulation of satiety and body weight, antimicrobial activity, and the induction of <a href=\"https:\/\/en.wikipedia.org\/wiki\/Apoptosis\" target=\"_blank\" rel=\"noopener\">apoptosis<\/a> (programmed cell death) in cancer cells. As for <a href=\"https:\/\/www.testmottagningen.se\/en\/markorer\/bakterier\/propionsyrabakterier\/\" target=\"_blank\" rel=\"noopener\">propionic acid<\/a>, also related to the release of hormones that increase the sensation of satiety and may reduce food intake, an increase is observed during the first 24 hours with red pepper fibre and at 48 hours with cucumber fibre.<\/p>\n<p>\u201cDietary fibre concentrates derived from vegetables not only help to maintain colon pH, but also promote the production of short-chain fatty acids, thus favouring intestinal health,\u201d highlights Gemma Bell\u00ed, professor at the Faculty of Medicine of the UdL and first author of the article. \u201cThose from artichoke in particular may represent a promising candidate for future research as a functional dietary ingredient,\u201d she adds.<\/p>\n<p>This study was jointly led by Bell\u00ed and Olga Mart\u00edn-Belloso, Professor of Food Technology at the UdL and head of the New Food Processing Technologies group at Agrotecnio. Ana A. Vaz, Isabel Odriozola-Serrano and Gemma Oms-Oliu also participated. The research team proposes future <em>in vivo<\/em> studies to confirm these effects of vegetable fibres under real physiological conditions.<\/p>\n<p><strong>MORE INFORMATION:<\/strong><br \/>Article: <a href=\"https:\/\/www.sciencedirect.com\/science\/article\/pii\/S2667025925000639\" target=\"_blank\" rel=\"noopener\"><em>Exploring the prebiotic potential of dietary fibre concentrates from artichoke, red pepper, cucumber, and carrot by-products<\/em><\/a><\/p>\n\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<div class=\"z-0 flex min-h-[46px] justify-start\">Text: Press UdL &#8211; Agrotecnio\n Photo: Press UdL<\/div>\n<div class=\"mt-3 w-full empty:hidden\"><\/div>\n<\/div>\n<\/div>\n<\/article><\/div>\n<\/div>\n<div id=\"thread-bottom-container\" class=\"sticky bottom-0 group\/thread-bottom-container relative isolate z-10 w-full basis-auto has-data-has-thread-error:pt-2 has-data-has-thread-error:[box-shadow:var(--sharp-edge-bottom-shadow)] md:border-transparent md:pt-0 dark:border-white\/20 md:dark:border-transparent print:hidden content-fade single-line flex flex-col\">\n<div id=\"thread-bottom\">\n<div class=\"text-base mx-auto [--thread-content-margin:--spacing(4)] @w-sm\/main:[--thread-content-margin:--spacing(6)] @w-lg\/main:[--thread-content-margin:--spacing(16)] px-(--thread-content-margin)\">\n<div class=\"[--thread-content-max-width:40rem] @w-lg\/main:[--thread-content-max-width:48rem] mx-auto max-w-(--thread-content-max-width) flex-1 mb-4\">\n<div class=\"pointer-events-auto relative z-1 flex h-(--composer-container-height,100%) max-w-full flex-(--composer-container-flex,1) flex-col\">\n<div class=\"absolute start-0 end-0 bottom-full z-20\"><\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>A study by the UdL, Agrotecnio and the IRBLleida shows that fibre concentrates left over from juice production can improve the intestinal microbiota and promote the production of short-chain fatty acids beneficial for the colon.
