Qu'est-ce que le Galactomannan-PHGG ?<\/strong><\/p>\n

Le galactomannane est un pr\u00e9biotique obtenu par hydrolyse des graines de guar, une mati\u00e8re premi\u00e8re tr\u00e8s soluble et stable qui peut \u00eatre hautement ferment\u00e9e et utilis\u00e9e par la flore intestinale. L'acide gras \u00e0 cha\u00eene courte (acide butyrique) obtenu par fermentation est un nutriment pour les villosit\u00e9s intestinales et poss\u00e8de donc les propri\u00e9t\u00e9s d'un pr\u00e9biotique.<\/p>\n

Le galactomannane est une nouvelle mati\u00e8re premi\u00e8re de fibre alimentaire fonctionnelle qui peut \u00eatre utilis\u00e9e comme additif alimentaire dans les aliments g\u00e9n\u00e9raux et comme am\u00e9liorateur nutritionnel dans les aliments sp\u00e9cialis\u00e9s.<\/p>\n

Du guar au PHGG :<\/strong><\/p>\n

Le pass\u00e9 et le pr\u00e9sent des galactomannanes<\/strong><\/p>\n

Tout d'abord, la f\u00e8ve de guar<\/strong><\/p>\n

Originaire de la frange d\u00e9sertique occidentale du sous-continent indo-pakistanais, il s'agit d'une herbe annuelle \u00e9rig\u00e9e du genre Guar. Ses graines contiennent 26% de prot\u00e9ines et une petite quantit\u00e9 de mati\u00e8res grasses, avec une composition \u00e9quilibr\u00e9e et compl\u00e8te en acides amin\u00e9s, riche en nutriments.<\/p>\n

Il y a ensuite la gomme de guar :<\/strong><\/p>\n

La gomme de guar est obtenue par traitement de la couche interm\u00e9diaire de l'endosperme (contenant principalement des galactomannanes) des f\u00e8ves de guar apr\u00e8s \u00e9limination de l'enveloppe ext\u00e9rieure de la graine, de l'embryon le plus \u00e0 l'int\u00e9rieur et des cotyl\u00e9dons. La gomme de guar est un collo\u00efde hydrophile naturel de grande taille, appartenant aux galactomannanes naturels, c'est un \u00e9paississant naturel et un am\u00e9liorateur de qualit\u00e9.<\/p>\n

Et enfin PHGG<\/strong><\/p>\n

\"\"<\/p>\n

Formule mol\u00e9culaire du galactomannane (rapport mannose\/galactose de 2:1)
\nLe galactomannane est l'ingr\u00e9dient principal de la d\u00e9gradation pr\u00e9cise et stable des mati\u00e8res premi\u00e8res \u00e0 grandes mol\u00e9cules en produits PHGG \u00e0 petites mol\u00e9cules dont nous avons besoin.<\/p>\n

L'efficacit\u00e9 du galactomannane-PHGG est remarquable<\/strong><\/p>\n

1. am\u00e9liorer l'\u00e9quilibre des micro-organismes intestinaux et augmenter les bact\u00e9ries b\u00e9n\u00e9fiques dans les intestins.<\/strong><\/p>\n

L'\u00e9quipe du Dr Missy Yanchun de l'Acad\u00e9mie des sciences m\u00e9dicales du Zhejiang a \u00e9tudi\u00e9 l'impact des fibres alimentaires sur la fonction intestinale \u00e0 l'aide d'exp\u00e9riences sur des souris et a constat\u00e9 que : apr\u00e8s avoir ajout\u00e9 une certaine quantit\u00e9 de galactomannane au r\u00e9gime alimentaire des souris, la teneur en acide ac\u00e9tique, en acide propionique, en acide butyrique et en acide lactique dans le tractus intestinal a \u00e9t\u00e9 consid\u00e9rablement am\u00e9lior\u00e9e, et les acides gras \u00e0 cha\u00eene courte sont la source nutritionnelle la plus importante des cellules villositaires de l'intestin.<\/p>\n

\"\"<\/p>\n

2. Contr\u00f4le de la glyc\u00e9mie postprandiale et am\u00e9lioration du statu quo des r\u00e9gimes \u00e0 IG \u00e9lev\u00e9<\/strong>
\nLe suivi de l'indice glyc\u00e9mique postprandial normal de 10 adultes en bonne sant\u00e9 a r\u00e9v\u00e9l\u00e9 que la consommation de galactomannane peut r\u00e9duire efficacement l'augmentation de la glyc\u00e9mie postprandiale.\"\"<\/p>\n

3. La consommation de galactomannane augmente efficacement l'apport en fer et en magn\u00e9sium et favorise l'absorption des min\u00e9raux.<\/strong>
\nLa plupart des fibres alimentaires limitent l'absorption de certaines vitamines et min\u00e9raux, alors que le galactomannane favorise l'absorption du calcium et du magn\u00e9sium chez les rats.<\/p>\n

\"\"<\/p>\n

4. Le galactomannane est agr\u00e9able \u00e0 utiliser, ne provoque pas de flatulences ni de diarrh\u00e9es, peut am\u00e9liorer efficacement la constipation et la diarrh\u00e9e.<\/strong><\/p>\n

\"\"<\/p>\n

La population exp\u00e9rimentale a \u00e9t\u00e9 divis\u00e9e en quatre groupes : groupe normal (contr\u00f4le), SCI de type diarrh\u00e9e, SCI interactif et SCI de type constipation. Les patients souffrant de SCI ont consomm\u00e9 du galactomannane (10 g\/j), tandis que le groupe normal n'en a pas consomm\u00e9, et les selles de la premi\u00e8re semaine, de la quatri\u00e8me semaine, de la huiti\u00e8me semaine et de la douzi\u00e8me semaine ont \u00e9t\u00e9 enregistr\u00e9es.<\/p>\n

Il a \u00e9t\u00e9 d\u00e9montr\u00e9 que le galactomannane avait un effet sur l'am\u00e9lioration de la d\u00e9f\u00e9cation chez les trois types de patients atteints du syndrome gastro-intestinal allergique. Le nombre de selles se normalisera (diminuera) dans le cas du syndrome gastro-intestinal de type diarrh\u00e9e et du syndrome gastro-intestinal interactif, et le syndrome gastro-intestinal de type constipation augmentera le nombre de selles et se normalisera.<\/p>\n

5. \u00c9viter efficacement les dommages caus\u00e9s par l'alcool et prot\u00e9ger le foie<\/strong><\/p>\n

Le galactomannane peut am\u00e9liorer de mani\u00e8re significative les l\u00e9sions h\u00e9patiques caus\u00e9es par une mauvaise structure alimentaire, l'alcool, etc. Il peut maintenir l'int\u00e9grit\u00e9 des membranes des cellules h\u00e9patiques endommag\u00e9es par l'alcool, r\u00e9duire efficacement les l\u00e9sions h\u00e9patiques aigu\u00ebs induites par l'alcool, maintenir la structure des membranes mitochondriales des h\u00e9patocytes et att\u00e9nuer l'apoptose des h\u00e9patocytes induite par l'alcool.<\/p>\n

6. Retarder le vieillissement, augmenter l'activit\u00e9 antioxydante, am\u00e9liorer le m\u00e9tabolisme des radicaux d'oxyg\u00e8ne<\/strong>
\nLes donn\u00e9es du tableau montrent que le groupe ayant re\u00e7u la dose \u00e9lev\u00e9e a r\u00e9duit de mani\u00e8re significative la quantit\u00e9 de substances vieillissantes dans les tissus, tandis que la dose moyenne de galactomannane a augment\u00e9 de mani\u00e8re significative la capacit\u00e9 antioxydante des tissus c\u00e9r\u00e9braux. Les exp\u00e9riences sur les animaux montrent que le PHGG peut promouvoir l'expression du facteur neurotrophique d\u00e9riv\u00e9 du cerveau et de la choline ac\u00e9tyltransf\u00e9rase dans l'hippocampe des rats, affectant ainsi favorablement les fonctions d'apprentissage et de m\u00e9moire du cerveau, et peut effectivement inverser l'expression des g\u00e8nes de vieillissement pertinents dans l'hippocampe des rats.<\/p>\n

\"\"<\/p>\n

7. En tant que fibre alimentaire hydrosoluble, elle peut am\u00e9liorer efficacement les taux de lipides sanguins.<\/strong><\/p>\n

Les taux \u00e9lev\u00e9s de cholest\u00e9rol et de triglyc\u00e9rides dans le sang sont consid\u00e9r\u00e9s comme des facteurs de risque cl\u00e9s pour les maladies cardiaques et les accidents vasculaires c\u00e9r\u00e9braux. Le galactomannane-PHGG, en tant que fibre alimentaire hydrosoluble, a pour effet b\u00e9n\u00e9fique de r\u00e9duire la teneur en graisses et d'am\u00e9liorer le m\u00e9tabolisme des graisses.<\/p>\n

8. R\u00e9duire les graisses et contr\u00f4ler facilement le poids corporel<\/strong><\/p>\n

La structure fibreuse du galactomannane sera enti\u00e8rement dispers\u00e9e dans l'estomac, absorbant le sucre et les graisses et augmentant la sati\u00e9t\u00e9 par sa propre expansion. Les micro-organismes de la muqueuse gastro-intestinale r\u00e9parent la paroi intestinale en absorbant le sucre et les graisses et en produisant des acides gras \u00e0 cha\u00eene courte, b\u00e9n\u00e9fiques pour la sant\u00e9 humaine. Les nutriments non absorb\u00e9s sont excr\u00e9t\u00e9s naturellement, ce qui \u00e9quivaut \u00e0 m\u00e9taboliser une partie des calories que le corps aurait d\u00fb absorber.<\/p>\n
