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

Le tripolyphosphate de sodium de qualit\u00e9 alimentaire est une poudre cristalline blanche ou un solide granuleux, tr\u00e8s soluble dans l'eau, avec un pH l\u00e9g\u00e8rement alcalin (9,2-10,0 dans une solution de 1%). Il poss\u00e8de de fortes propri\u00e9t\u00e9s ch\u00e9latrices pour les ions m\u00e9talliques comme le calcium et le magn\u00e9sium, ce qui le rend efficace pour l'adoucissement de l'eau et l'\u00e9mulsification. Il fond \u00e0 622\u00b0C et se d\u00e9compose en chauffant, lib\u00e9rant des phosphates. Le compos\u00e9 est hygroscopique et doit \u00eatre stock\u00e9 dans des conditions s\u00e8ches pour \u00e9viter qu'il ne s'agglom\u00e8re. Il est non toxique et largement utilis\u00e9 dans l'industrie alimentaire comme stabilisateur et agent de r\u00e9tention de l'humidit\u00e9.<\/p>\n

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

Dans l'industrie alimentaire, il sert \u00e0 am\u00e9liorer la qualit\u00e9. Il est utilis\u00e9 dans les produits carn\u00e9s pour retenir l'eau, maintenir la texture et la jutosit\u00e9. Dans les fruits de mer, il emp\u00eache la d\u00e9coloration. Dans les produits \u00e0 base de farine, il am\u00e9liore l'\u00e9lasticit\u00e9 et la r\u00e9sistance. Il sert \u00e9galement d'\u00e9mulsifiant dans les produits laitiers et les boissons, avec des niveaux d'utilisation typiques allant de 0,1% \u00e0 0,5% en fonction du type d'aliment, conform\u00e9ment aux r\u00e9glementations relatives aux additifs alimentaires.<\/p>\n

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

Emball\u00e9s dans des sacs en plastique tiss\u00e9 recouverts de poly\u00e9thyl\u00e8ne ou dans des sacs en papier, d'un poids net de 25 ou 50 kg. Stocker dans un entrep\u00f4t frais, sec et bien ventil\u00e9. \u00c9viter l'humidit\u00e9, la lumi\u00e8re directe du soleil et le contact avec les acides. Garder le produit scell\u00e9 pour \u00e9viter qu'il ne s'agglom\u00e8re et que sa qualit\u00e9 ne se d\u00e9t\u00e9riore. La dur\u00e9e de conservation est d'environ 24 mois dans des conditions de stockage ad\u00e9quates.<\/p>","protected":false},"excerpt":{"rendered":"
