<\/span>Qu’est-ce que l’ascorbate de sodium ?<\/span><\/h2>\n

La teinte de l’ascorbate de sodium, qui est cristallin et peut \u00eatre blanche ou l\u00e9g\u00e8rement jaune, varie. C’est une mati\u00e8re organique. Il est inodore et relativement stable \u00e0 l’\u00e9tat sec. Il peut \u00eatre utilis\u00e9 comme exhausteur de nutriments alimentaires dans l’industrie alimentaire, comme colorant et antioxydant. Il joue le m\u00eame r\u00f4le que la vitamine C. Il existe deux principaux proc\u00e9d\u00e9s de pr\u00e9paration de l’ascorbate de sodium :<\/p>\n

1. Utiliser la vitamine C (acide ascorbique) et le sel de sodium (comme l’hydroxyde de sodium) comme mati\u00e8res premi\u00e8res. Utiliser l’extraction par solvant, la cristallisation et d’autres techniques de s\u00e9paration pour \u00e9liminer les impuret\u00e9s afin d’obtenir de l’ascorbate de sodium de haute puret\u00e9. En Chine, ce proc\u00e9d\u00e9 de pr\u00e9paration a une efficacit\u00e9 de production \u00e9lev\u00e9e, convient \u00e0 la production \u00e0 grande \u00e9chelle, a de faibles co\u00fbts de production et est relativement mature.<\/p>\n

2. Utiliser des micro-organismes sp\u00e9cifiques pour convertir les mati\u00e8res premi\u00e8res en ascorbate de sodium pendant la fermentation, mais le co\u00fbt de production de ce proc\u00e9d\u00e9 peut \u00eatre \u00e9lev\u00e9 et les exigences techniques sont complexes.<\/p>\n

<\/span>L’ascorbate de sodium a un large \u00e9ventail d’utilisations<\/span><\/h2>\n

1. L’ascorbate de sodium est un antioxydant puissant qui peut prolonger la dur\u00e9e de conservation des aliments en emp\u00eachant les graisses et les huiles de s’oxyder.<\/p>\n

2. En tant que source de vitamine C, il peut am\u00e9liorer la valeur nutritionnelle des aliments et aider \u00e0 reconstituer la vitamine C dont le corps humain a besoin.<\/p>\n

3. Il peut inhiber la croissance de certains micro-organismes, jouant ainsi un r\u00f4le de conservateur.<\/p>\n

4. Dans certains aliments et boissons, l’ascorbate de sodium peut aider \u00e0 stabiliser d’autres ingr\u00e9dients et \u00e0 les emp\u00eacher de se g\u00e2ter.<\/p>\n

<\/span>Question pos\u00e9e par l’utilisateur :<\/span><\/h2>\n

Fran\u00e7ais : Question : Quelle est la diff\u00e9rence entre l’ascorbate de sodium et la vitamine C ordinaire ?<\/p>\n

R\u00e9ponse : 1. L’ascorbate de sodium est plus stable que la vitamine C ordinaire, en particulier dans un environnement acide, et ne s’oxyde pas ou ne se d\u00e9grade pas facilement, ce qui lui permet de conserver une dur\u00e9e de conservation plus longue lorsqu’il est utilis\u00e9 dans les aliments et les produits de sant\u00e9.<\/p>\n

2. L’ascorbate de sodium a une acidit\u00e9 plus faible et est g\u00e9n\u00e9ralement moins irritant pour l’estomac, il convient donc mieux aux personnes sensibles aux substances acides.<\/p>\n

3. L’ascorbate de sodium est souvent utilis\u00e9 dans les aliments et les produits de sant\u00e9 et peut remplacer la vitamine C ordinaire pour am\u00e9liorer la stabilit\u00e9 et r\u00e9duire l’irritation gastro-intestinale.<\/p>\n","protected":false},"excerpt":{"rendered":"
