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

Le pyrophosphate de sodium de qualit\u00e9 alimentaire est une poudre cristalline blanche ou un solide granuleux, tr\u00e8s soluble dans l'eau mais insoluble dans l'alcool. Il a un pH fortement alcalin (9,9-10,7 dans une solution de 10 g\/L) et agit comme un agent ch\u00e9lateur pour les ions m\u00e9talliques. La forme anhydre fond \u00e0 880\u00b0C, tandis que le d\u00e9cahydrate perd de l'eau \u00e0 100\u00b0C. Il est hygroscopique, absorbant l'humidit\u00e9 de l'air, et s'hydrolyse en phosphate disodique lorsqu'il est bouilli dans l'eau<\/p>\n

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

En tant qu'additif alimentaire, il am\u00e9liore la qualit\u00e9. Dans les produits carn\u00e9s, il retient l'humidit\u00e9, am\u00e9liore la tendret\u00e9 et la jutosit\u00e9. Dans les fruits de mer, il emp\u00eache la d\u00e9coloration. Il est utilis\u00e9 dans les produits laitiers pour stabiliser les \u00e9mulsions et dans les produits de boulangerie pour am\u00e9liorer la texture. Il sert \u00e9galement de s\u00e9questrant dans les boissons, avec des niveaux d'utilisation g\u00e9n\u00e9ralement compris entre 0,05% et 0,5%, conform\u00e9ment \u00e0 la r\u00e9glementation sur les additifs alimentaires.<\/p>\n

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

Conditionn\u00e9s dans des sacs tiss\u00e9s rev\u00eatus de poly\u00e9thyl\u00e8ne, des sacs en papier ou des sacs en plastique composite, d'un poids net courant de 25 kg\/50 kg. Stocker dans un entrep\u00f4t frais, sec et 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":"
