Par cons\u00e9quent, la mani\u00e8re la plus courante et la plus efficace de ralentir l'oxydation des graisses et des huiles et de prolonger leur dur\u00e9e de conservation est d'ajouter des antioxydants aux graisses et aux huiles.<\/p>\n<p>La s\u00e9curit\u00e9 des antioxydants synth\u00e9tiques a \u00e9t\u00e9 remise en question en raison des nombreux probl\u00e8mes de s\u00e9curit\u00e9, tels que la t\u00e9ratog\u00e9nicit\u00e9, la canc\u00e9rog\u00e9nicit\u00e9 et les maladies chroniques associ\u00e9es \u00e0 une utilisation excessive.<\/p>\n<p>Les antioxydants naturels sont extraits de plantes et d'animaux et se caract\u00e9risent par une grande s\u00e9curit\u00e9, une forte capacit\u00e9 antioxydante, l'absence d'effets secondaires, l'anticorrosion et la pr\u00e9servation de la fra\u00eecheur.<\/p>\n<p>Les antioxydants naturels peuvent \u00eatre class\u00e9s en fonction de leurs m\u00e9canismes : absorbeurs de radicaux libres, ch\u00e9lateurs d'ions m\u00e9talliques, pi\u00e9geurs d'oxyg\u00e8ne, att\u00e9nuateurs d'oxyg\u00e8ne monolin\u00e9aires, d\u00e9composeurs d'hydroperoxydes, absorbeurs d'ultraviolets et antioxydants enzymatiques. Les antioxydants naturels courants se r\u00e9partissent principalement dans les cat\u00e9gories suivantes :<\/p>\n<p>I. Flavono\u00efdes<br \/>\nLes flavono\u00efdes sont une classe de compos\u00e9s qui existent dans la nature, avec la structure 2-ph\u00e9nylchromone des composants v\u00e9g\u00e9taux naturels de faible poids mol\u00e9culaire, le corps humain ne peut pas \u00eatre synth\u00e9tis\u00e9, il doit \u00eatre ing\u00e9r\u00e9 \u00e0 partir du monde ext\u00e9rieur. Leurs mol\u00e9cules ont un carbonyle c\u00e9tonique, la premi\u00e8re position de l'atome d'oxyg\u00e8ne avec alcalin, peut former des sels avec des acides forts, et ses d\u00e9riv\u00e9s hydroxyl\u00e9s ont une couleur jaune, c'est pourquoi il est \u00e9galement connu sous le nom de xanthophylles ou de flavono\u00efdes.<\/p>\n<p>Il existe deux types de m\u00e9canismes antioxydants des flavono\u00efdes :<\/p>\n<p>1, les ions m\u00e9talliques ch\u00e9lateurs peuvent former des ch\u00e9lates avec les ions m\u00e9talliques, r\u00e9duire l'activit\u00e9 catalytique des ions m\u00e9talliques, emp\u00eacher l'apparition de r\u00e9actions d'oxydation et constituer un bon moyen d'\u00e9liminer les esp\u00e8ces r\u00e9actives de l'oxyg\u00e8ne (ROS) et les esp\u00e8ces r\u00e9actives de l'azote.<\/p>\n<p>2, en pi\u00e9geant les radicaux libres, en fournissant des atomes d'hydrog\u00e8ne aux radicaux peroxyde d'hydrog\u00e8ne, en g\u00e9n\u00e9rant des hydroperoxydes stables, et le groupe hydroxyle ph\u00e9nolique de la mol\u00e9cule r\u00e9agit avec les radicaux oxyg\u00e8ne pour former des radicaux semiquinone conjugu\u00e9s stables, interrompant la r\u00e9action en cha\u00eene des radicaux libres.<\/p>\n<p>Exemples d'antioxydants naturels de type flavono\u00efde :<\/p>\n<p>1, l'extrait de coque d'arachide, avec le composant actif antioxydant 3,4,5,7-t\u00e9trahydroxyflavone, est un inhibiteur de radicaux libres auto-oxydants, son activit\u00e9 antioxydante est \u00e9quivalente \u00e0 celle de l'hydroxytolu\u00e8ne butyl\u00e9 (BHT), plus \u00e9lev\u00e9e que celle du tocoph\u00e9rol.<\/p>\n<p>2. Extrait de r\u00e9glisse, contenant de la chalcone de r\u00e9glisse A, de la chalcone de r\u00e9glisse B et des isoflavones de r\u00e9glisse, avec une forte capacit\u00e9 de pi\u00e9geage des radicaux libres et d'inhibition de l'oxydation enzymatique.<\/p>\n<p>3, Proanthocyanidines, l'inhibition de l'oxydation des lipides est significative, la l\u00e9cithine et la vitamine E ont un bon effet sur la potentialisation des proanthocyanidines. Dans l'inhibition de l'activit\u00e9 de l'oxydase des graisses, les proanthocyanidines et les polyph\u00e9nols du th\u00e9 ont le m\u00eame effet.<\/p>\n<p>4, d'autres, l'extrait de galanga dans le galanga, la rutine dans l'acacia, l'apig\u00e9nine dans l'origan et la querc\u00e9tine dans le jindiro appartiennent aux flavono\u00efdes, et leur capacit\u00e9 antioxydante sur les graisses et les huiles est \u00e9quivalente \u00e0 celle de l'hydroxytolu\u00e8ne butyl\u00e9 (BHT) ou sup\u00e9rieure \u00e0 celle de l'hydroxytolu\u00e8ne butyl\u00e9 (BHT).<\/p>\n<p>Polyph\u00e9nols<br \/>\nLes compos\u00e9s polyph\u00e9noliques sont un groupe de plantes dans les substances chimiques collectivement, en raison du groupe ph\u00e9nolique et de son nom. Ils peuvent \u00eatre divis\u00e9s en deux cat\u00e9gories : l'une est un monom\u00e8re de polyph\u00e9nol, comprenant l'acide chlorog\u00e9nique, l'acide ellagique, ainsi qu'un certain nombre de compos\u00e9s polyph\u00e9noliques composites contenant des glycosides ; l'autre est un monom\u00e8re de polyph\u00e9nol polym\u00e9risant des oligom\u00e8res ou des polym\u00e8res, collectivement appel\u00e9s substances de type tannin.<\/p>\n<p>Exemples de polyph\u00e9nols antioxydants naturels :<\/p>\n<p>1, polyph\u00e9nols de th\u00e9, son activit\u00e9 antioxydante est de 2,6 fois l'hydroxyanisole butyl\u00e9 (BHA), soit 3,6 fois la vitamine E. Le polyph\u00e9nol de th\u00e9 \u00e9tant soluble dans l'eau, il doit \u00eatre modifi\u00e9 en type soluble dans l'huile pour mieux jouer son r\u00f4le dans les graisses et les huiles.<\/p>\n<p>2, le resv\u00e9ratrol, provenant principalement des arachides, du raisin (vin rouge), du thuya, des m\u00fbres et d'autres plantes, le resv\u00e9ratrol est un compos\u00e9 polyph\u00e9nolique, connu pour son activation efficace des prot\u00e9ines de long\u00e9vit\u00e9 - les d\u00e9ac\u00e9tylases (sirtuines). les sirtuines sont un facteur important dans le ralentissement de la s\u00e9nescence cellulaire et la prolongation de la vie en r\u00e9gulant une vari\u00e9t\u00e9 de processus cellulaires. L'inhibition de la s\u00e9nescence cellulaire par les sirtuines est principalement m\u00e9di\u00e9e par le retardement de la perte des t\u00e9lom\u00e8res li\u00e9e \u00e0 l'\u00e2ge, le maintien de l'int\u00e9grit\u00e9 du g\u00e9nome et la promotion de la r\u00e9paration des l\u00e9sions de l'ADN.<\/p>\n<p>Pigments naturels<br \/>\nLes pigments naturels contiennent un grand nombre de groupes hydroxyle ph\u00e9noliques, ce qui leur conf\u00e8re une capacit\u00e9 efficace de pi\u00e9geage du radical hydroxyle et du radical peroxyle. Ils poss\u00e8dent \u00e9galement de fortes propri\u00e9t\u00e9s r\u00e9ductrices, peuvent faire \u00e9clater l'oxyg\u00e8ne simple-lin\u00e9aire et constituent un antioxydant naturel tr\u00e8s prometteur pour les huiles, et leur capacit\u00e9 antioxydante est plusieurs fois sup\u00e9rieure \u00e0 celle des vitamines (par exemple, vitamine C, vitamine E). Les pigments naturels courants comprennent le b\u00eata-carot\u00e8ne, le lycop\u00e8ne, l'astaxanthine, etc. L'inconv\u00e9nient des antioxydants \u00e0 base de pigments naturels est qu'ils sont peu solubles dans l'eau, qu'il n'est pas facile de m\u00e9langer les couleurs et qu'ils changent facilement de couleur.<\/p>\n<p>Certains chercheurs ont \u00e9tudi\u00e9 les propri\u00e9t\u00e9s antioxydantes de l'astaxanthine et d'autres cinq antioxydants naturels dans deux syst\u00e8mes d'huile comestible, et ont constat\u00e9 que l'astaxanthine\uff1e lycop\u00e8ne\uff1e vitamine C\uff1e vitamine E\uff1e \u03b2-carot\u00e8ne\uff1e lut\u00e9ine avait un effet antioxydant dans l'huile de canola, et que l'astaxanthine\uff1e lut\u00e9ine\uff1evitamine C\u2248 vitamine E\u2248 \u03b2-carot\u00e8ne\uff1e lycop\u00e8ne avait un effet antioxydant dans l'huile de soja.<\/p>\n<p>Quatri\u00e8mement, les vitamines et leurs d\u00e9riv\u00e9s<br \/>\nLes vitamines sont indispensables aux activit\u00e9s vitales de l'homme. La plupart d'entre elles ne peuvent pas \u00eatre synth\u00e9tis\u00e9es par l'organisme, ou ne le sont qu'en petites quantit\u00e9s, et doivent donc \u00eatre apport\u00e9es par l'alimentation ; la vitamine C, la vitamine E et le coenzyme Q ont une forte fonction antioxydante.<\/p>\n<p>1, la vitamine E, \u00e9galement connue sous le nom de tocoph\u00e9rol, est une classe importante de substances physiologiquement actives. Certains chercheurs pensent que sa fonction antioxydante ne se limite pas \u00e0 l'\u00e9limination des radicaux libres, mais qu'elle \u00e9limine \u00e9galement la formation de peroxydes lipidiques de sources potentielles, inhiber l'oxydation des acides gras polyinsatur\u00e9s dans la membrane des tissus autour des particules cellulaires et des \u00e9rythrocytes dans la membrane, et peut r\u00e9agir avec les peroxydes sera transform\u00e9 en inoffensif pour les cellules de la mati\u00e8re pour maintenir l'int\u00e9grit\u00e9 des membranes cellulaires des acides gras polyinsatur\u00e9s \u00e0 longue cha\u00eene, ce qui maintient la membrane cellulaire. Les acides gras insatur\u00e9s de la membrane cellulaire pr\u00e9servent l'int\u00e9grit\u00e9 de son activit\u00e9 biologique.<\/p>\n<p>2, la vitamine C, \u00e9galement connue sous le nom d'acide ascorbique, soluble dans l'eau, l\u00e9g\u00e8rement soluble dans l'ac\u00e9tone, son activit\u00e9 antioxydante est principalement r\u00e9alis\u00e9e par le pi\u00e9geage des radicaux libres, par l'apport d'\u00e9lectrons \u00e9tape par \u00e9tape dans la semi-d\u00e9shydrovitamine C, afin d'atteindre l'objectif de pi\u00e9geage des radicaux libres tels que OH-, ROO-.<\/p>\n<p>3\u3001La coenzyme Q10 est un compos\u00e9 de quinone, largement pr\u00e9sent dans les animaux, les plantes, les micro-organismes et d'autres cellules, g\u00e9n\u00e9ralement en tr\u00e8s faible quantit\u00e9. Dans l'organisme, il existe deux formes, oxyd\u00e9e et r\u00e9duite, qui peuvent se transformer l'une en l'autre, mais seule la forme r\u00e9duite peut jouer un r\u00f4le antioxydant, principalement en pi\u00e9geant les radicaux libres, en stabilisant la membrane cellulaire et en luttant contre l'apoptose.<\/p>\n<p>Peptide antioxydant<br \/>\nLes peptides antioxydants proviennent principalement de prot\u00e9ines animales et v\u00e9g\u00e9tales et de leurs produits d'hydrolyse.<\/p>\n<p>1, le peptide de soja, prot\u00e9ine de soja par hydrolyse enzymatique d'un certain poids mol\u00e9culaire de peptide, a une forte capacit\u00e9 \u00e0 inhiber les radicaux libres, mais aussi \u00e0 inhiber l'activit\u00e9 de la lipoxyg\u00e9nase, \u00e0 inhiber la voie : \u2460 complexe du site actif de l'enzyme Fe3 + ; \u2461 et le substrat en comp\u00e9tition pour le site actif de l'enzyme ; \u2462 et les mol\u00e9cules de l'enzyme interagissent avec l'enzyme ou modifient la structure spatiale de l'enzyme, r\u00e9duisant ainsi l'activit\u00e9 de l'enzyme.<\/p>\n<p>2, le glutathion, compos\u00e9 d'acide glutamique, de cyst\u00e9ine et de glycine, appel\u00e9 GSH, la mol\u00e9cule pr\u00e9sente un \u00e9tat r\u00e9duit de sulfhydryl-SH, ce qui lui conf\u00e8re des propri\u00e9t\u00e9s antioxydantes. Voie antioxydante : \u2460 blocage des radicaux libres ; \u2461 fixation de H\u2082O\u2082 ; \u2462 pi\u00e9geage des peroxydes d'ester.<\/p>\n<p>Six, polysaccharide actif<br \/>\nLe polysaccharide est une sorte de polym\u00e8re naturel, g\u00e9n\u00e9ralement constitu\u00e9 de plus de 10 monosaccharides reli\u00e9s par des liaisons glycosidiques en cha\u00eene droite ou ramifi\u00e9e, avec un poids mol\u00e9culaire de quelques dizaines de milliers \u00e0 quelques millions (le hyaluronate de sodium est \u00e9galement consid\u00e9r\u00e9 comme une sorte de polysaccharide).<\/p>\n<p>Des \u00e9tudes ont montr\u00e9 que les polysaccharides de ginseng et les polysaccharides de prune de bambou ont un meilleur effet de pi\u00e9geage sur les radicaux -OH, que les polysaccharides de myrtille ont un effet de pi\u00e9geage plus important sur les radicaux -OH et DPPH, et que les polysaccharides de gingembre ont un meilleur effet de pi\u00e9geage sur les radicaux DPPH- que sur les radicaux -OH.<\/p>\n<h1><strong><b>Contactez-nous d\u00e8s maintenant !<\/b><\/strong><\/h1>\n<h4><strong><b>Si vous avez besoin de Price, veuillez indiquer vos coordonn\u00e9es dans le formulaire ci-dessous.

topics<\/h2>\n<p>In enzyme and food-processing projects, the most useful decision frame is usually application fit plus process stability: which ingredient performs under the intended pH, temperature, time, and substrate conditions without creating a downstream quality or compliance problem.<\/p>\n<ul>\n<li><strong>Define the processing target first:<\/strong> flavor, hydrolysis, texture, fermentation, cleaning, and bioprocess applications often need very different activity profiles.<\/li>\n<li><strong>Check the real operating window:<\/strong> pH, temperature, residence time, and substrate type often matter more than a headline product claim.<\/li>\n<li><strong>Review consistency and downstream impact:<\/strong> dosage, sensory influence, filtration, and shelf-life behavior can all affect the final commercial value.<\/li>\n<li><strong>Use pilot validation:<\/strong> small production tests usually reveal the most useful differences in activity, efficiency, and process fit.<\/li>\n<\/ul>\n<h3>Recommended product references<\/h3>\n<ul>\n<li><strong><a href=\"https:\/\/longchangchemical.com\/fr\/product\/chlumiao-1010-cas-6683-19-8\/\">CHLUMIAO 1010<\/a>:<\/strong> A

choice?<\/strong><br \/>Because the best enzyme is the one that performs reliably under the actual process conditions and gives the desired downstream result without creating new issues.<\/p>\n<p><strong>Should food and biotech ingredients be selected from data sheets alone?<\/strong><br \/>It is usually safer to pair the specification review with a pilot or application test because real substrates and process windows can change the result a lot.<\/p>\n<p><!-- lc-commercial-end --><\/p>","protected":false},"excerpt":{"rendered":"<p>Antioxidants act as hydrogen donors and
