1\u3001Propri\u00e9t\u00e9 du produit<\/b><\/strong><\/h4>\n

La carboxym\u00e9thylcellulose sodique (CMC) est une poudre hygroscopique, inodore, de couleur blanche \u00e0 blanc cass\u00e9. Elle se dissout facilement dans l'eau pour former des solutions collo\u00efdales visqueuses, dont la viscosit\u00e9 d\u00e9pend de la concentration, de la temp\u00e9rature et du degr\u00e9 de substitution (DS). La CMC est insoluble dans les solvants organiques et pr\u00e9sente une excellente stabilit\u00e9 dans une large gamme de pH (2-10). En tant que polym\u00e8re non toxique et biod\u00e9gradable, elle sert d'\u00e9paississant, de stabilisateur et de liant dans les aliments, les produits pharmaceutiques et les applications industrielles.<\/p>\n

3. Champ d'application et utilisation<\/b><\/strong><\/h4>\n

La CMC-Na est un additif alimentaire multifonctionnel, principalement utilis\u00e9 comme \u00e9paississant, stabilisateur et agent de r\u00e9tention de l'humidit\u00e9 dans divers produits. Il am\u00e9liore la texture des cr\u00e8mes glac\u00e9es, pr\u00e9vient la syn\u00e9r\u00e8se dans les produits laitiers et am\u00e9liore la sensation en bouche dans les boissons. Le compos\u00e9 agit comme un liant dans les produits de boulangerie et comme un agent de suspension dans les vinaigrettes\/sauces. Dans les produits all\u00e9g\u00e9s, il imite la fonctionnalit\u00e9 des mati\u00e8res grasses. Les applications pharmaceutiques comprennent la liaison des comprim\u00e9s et les formulations \u00e0 lib\u00e9ration contr\u00f4l\u00e9e.<\/p>\n

4. Emballage et stockage<\/b><\/strong><\/h4>\n

La CMC-Na est conditionn\u00e9e dans des sacs en papier kraft multicouches de 25 kg avec une doublure en poly\u00e9thyl\u00e8ne ou dans des f\u00fbts en fibre de 20 kg. Le stockage n\u00e9cessite un environnement sec et ventil\u00e9 \u00e0 une temp\u00e9rature inf\u00e9rieure \u00e0 25\u00b0C et une humidit\u00e9 relative inf\u00e9rieure \u00e0 65%. Les conteneurs doivent rester scell\u00e9s pour \u00e9viter l'absorption d'humidit\u00e9 et l'agglom\u00e9ration. \u00c9viter la lumi\u00e8re directe du soleil et stocker \u00e0 l'abri des oxydants puissants. Dans des conditions optimales, la dur\u00e9e de conservation est de 24 mois.<\/p>","protected":false},"excerpt":{"rendered":"
