Annonce nationale<\/strong><\/p>\n

Le 26 mai 2008, le minist\u00e8re de la sant\u00e9 a publi\u00e9 l'annonce relative \u00e0 l'approbation de sept nouveaux aliments, dont le Lactobacillus Acidophilus (annonce n\u00b0 12 de 2008 du minist\u00e8re de la sant\u00e9), qui a officiellement approuv\u00e9 l'ester de lut\u00e9ine en tant que nouvel aliment et a fix\u00e9 les exigences suivantes concernant sa composition, sa source, son processus, son champ d'application, sa taille de portion et ses sp\u00e9cifications de qualit\u00e9 :<\/p>\n

\"\"<\/p>\n

Caract\u00e9risation de la conversion in vivo des esters de lut\u00e9ine<\/strong><\/p>\n

Au cours de la digestion, l'organisme hydrolyse efficacement les esters de lut\u00e9ine et lib\u00e8re la lut\u00e9ine libre, qui est ensuite absorb\u00e9e dans la circulation sanguine.<\/p>\n

Des \u00e9tudes ont montr\u00e9 que l'ingestion d'esters de lut\u00e9ine augmente les niveaux de lut\u00e9ine dans le sang et la macula de la r\u00e9tine. L'absorption des carot\u00e9no\u00efdes, dont la lut\u00e9ine, par l'organisme est un processus en plusieurs \u00e9tapes. Ce processus est le m\u00eame que pour les autres composants liposolubles pr\u00e9sents dans l'alimentation.<\/p>\n

La lut\u00e9ine peut donc \u00eatre ing\u00e9r\u00e9e avec des graisses. La conversion des esters de lut\u00e9ine en lut\u00e9ine est un processus physiologique naturel dans l'organisme. Soutien scientifique et preuves cliniques L'ester de lut\u00e9ine a \u00e9t\u00e9 reconnu par l'\u00e9quipe scientifique comme l'une des sources s\u00fbres de lut\u00e9ine.<\/p>\n

Fonctions des esters de lut\u00e9ine<\/strong><\/p>\n

Effets colorants de l'ester de lut\u00e9ine<\/strong><\/p>\n

L'ester de lut\u00e9ine naturelle est un important ester d'acide gras de carot\u00e9no\u00efde, la configuration principale est tout-trans, avec une longue cha\u00eene C = C du groupe colorant, montrant un jaune dor\u00e9 brillant, il n'y a pas de groupe hydroxyle actif des deux c\u00f4t\u00e9s, ce qui d\u00e9termine \u00e9galement que l'ester de lut\u00e9ine est une sorte d'agent colorant alimentaire tr\u00e8s stable.<\/p>\n

Il est tr\u00e8s stable \u00e0 la lumi\u00e8re, \u00e0 la chaleur et \u00e0 l'air, et peut \u00eatre largement utilis\u00e9 dans l'alimentation, les boissons, les cosm\u00e9tiques et d'autres applications, avec de vastes perspectives d'application. En m\u00eame temps, il peut \u00eatre transform\u00e9 en colorant soluble dans l'eau apr\u00e8s \u00e9mulsification. L'ester naturel de lut\u00e9ine remplacera les colorants de qualit\u00e9 alimentaire synth\u00e9tis\u00e9s chimiquement et am\u00e9liorera la sant\u00e9 des personnes.<\/p>\n

Pr\u00e9venir l'utilisation d'ADM<\/strong><\/p>\n

Une fonction biologique importante de la lut\u00e9ine est de prot\u00e9ger la r\u00e9tine des dommages caus\u00e9s par les UV. Actuellement, la d\u00e9g\u00e9n\u00e9rescence maculaire li\u00e9e \u00e0 l'\u00e2ge (DMLA) est la principale maladie oculaire c\u00e9citante chez les personnes \u00e2g\u00e9es de plus de 65 ans.<\/p>\n

Apr\u00e8s avoir \u00e9t\u00e9 ing\u00e9r\u00e9s dans le corps humain, les esters naturels de lut\u00e9ine et de z\u00e9axanthine sont hydrolys\u00e9s en lut\u00e9ine et z\u00e9axanthine sous forme libre par l'action de la lipase humaine. Ils sont d\u00e9pos\u00e9s en forte concentration dans la macula du fond de l'\u0153il humain, qui peut agir comme un absorbeur de lumi\u00e8re bleue proche de l'ultraviolet, et exercer un effet protecteur en capturant les radicaux libres, en emp\u00eachant ou en r\u00e9duisant les dommages caus\u00e9s par l'oxydation et les radicaux libres \u00e0 la r\u00e9tine, ce qui peut r\u00e9duire efficacement l'incidence de la maladie d'Alzheimer.<\/p>\n

Renforcement de l'immunit\u00e9<\/strong><\/p>\n

Des \u00e9tudes r\u00e9centes ont montr\u00e9 qu'une suppl\u00e9mentation en lut\u00e9ine dans l'organisme favorise les r\u00e9ponses prolif\u00e9ratives des lymphocytes stimul\u00e9es par les antig\u00e8nes et peut influencer l'expression fonctionnelle des mol\u00e9cules de surface des cellules au niveau de l'animal dans son ensemble. L'effet modulateur de la lut\u00e9ine sur l'immunit\u00e9 cellulaire se manifeste principalement dans sa relation avec l'apoptose et la r\u00e9gulation des g\u00e8nes.<\/p>\n

Soins de la peau et protection du c\u0153ur<\/strong><\/p>\n

En tant qu'antioxydant puissant, l'ester de lut\u00e9oline peut inhiber l'activit\u00e9 des radicaux r\u00e9actifs de l'oxyg\u00e8ne et emp\u00eacher la destruction des cellules normales de la peau par les radicaux r\u00e9actifs de l'oxyg\u00e8ne. Par cons\u00e9quent, les esters de lut\u00e9ine peuvent \u00eatre transform\u00e9s en une vari\u00e9t\u00e9 de produits de soins de la peau et de cosm\u00e9tiques, qui sont utilis\u00e9s pour prot\u00e9ger la sant\u00e9 de la peau et pr\u00e9venir les dommages cutan\u00e9s.<\/p>\n

Certaines \u00e9tudes ont indiqu\u00e9 que les personnes qui consomment r\u00e9guli\u00e8rement des carot\u00e9no\u00efdes ont un risque r\u00e9duit de maladie cardiovasculaire. En 1994, Morrs et al. ont constat\u00e9 que les niveaux sanguins de carot\u00e9no\u00efdes totaux \u00e9taient inversement li\u00e9s au risque de d\u00e9velopper une maladie coronarienne.<\/p>\n

Application des esters de lut\u00e9ine dans l'alimentation<\/strong><\/p>\n

Applications dans l'alimentation g\u00e9n\u00e9rale<\/strong><\/p>\n

Les esters de lut\u00e9ine peuvent \u00eatre utilis\u00e9s dans les produits de boulangerie, les produits laitiers, les boissons, les c\u00e9r\u00e9ales pr\u00eates \u00e0 consommer, les boissons surgel\u00e9es, les condiments et les confiseries, mais pas dans les aliments destin\u00e9s aux nourrissons et aux jeunes enfants. La posologie est de \u226412mg\/jour.<\/p>\n

Application dans les aliments di\u00e9t\u00e9tiques<\/strong><\/p>\n

Selon les donn\u00e9es de la State Food and Drug Administration, il existe actuellement 265 produits di\u00e9t\u00e9tiques nationaux dont la mati\u00e8re premi\u00e8re principale est l'ester de lut\u00e9ine et dont la fonction sant\u00e9 revendiqu\u00e9e est principalement de soulager la fatigue visuelle.<\/p>","protected":false},"excerpt":{"rendered":"
