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

L'hydrog\u00e9nophosphate disodique de qualit\u00e9 alimentaire se pr\u00e9sente sous la forme d'une poudre cristalline blanche ou de granul\u00e9s. Il est tr\u00e8s soluble dans l'eau mais insoluble dans l'alcool. Le compos\u00e9 est stable dans des conditions normales et pr\u00e9sente des propri\u00e9t\u00e9s hygroscopiques. En tant qu'agent tampon, il maintient le pH entre 8,0 et 11,0 dans les solutions.<\/p>\n

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

L'hydrog\u00e9nophosphate disodique remplit de multiples fonctions dans la transformation des aliments en tant que r\u00e9gulateur d'acidit\u00e9, \u00e9mulsifiant et stabilisateur. Il est couramment utilis\u00e9 dans les produits laitiers, les fromages fondus et les produits carn\u00e9s pour am\u00e9liorer la texture et la r\u00e9tention d'eau. Dans les boissons, il agit comme un tampon de pH. Le compos\u00e9 trouve \u00e9galement des applications dans le traitement de l'eau et les d\u00e9tergents. En tant qu'additif alimentaire (E339ii), il doit \u00eatre utilis\u00e9 dans les limites autoris\u00e9es (g\u00e9n\u00e9ralement 0,3-0,5% dans les produits finis).<\/p>\n

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

Le produit est g\u00e9n\u00e9ralement conditionn\u00e9 dans des sacs tiss\u00e9s de 25 kg rev\u00eatus de poly\u00e9thyl\u00e8ne ou dans des f\u00fbts en fibre pour un usage industriel. Les quantit\u00e9s vendues au d\u00e9tail peuvent \u00eatre conditionn\u00e9es dans des conteneurs PEHD scell\u00e9s. Stocker dans un endroit frais, sec et bien ventil\u00e9, \u00e0 l'abri de l'humidit\u00e9 et des substances incompatibles. L'emballage doit rester herm\u00e9tiquement ferm\u00e9 pour \u00e9viter que le produit ne se fige en raison de sa nature hygroscopique. Dans des conditions de stockage appropri\u00e9es, la dur\u00e9e de conservation est de 24 mois. Pendant le transport, prot\u00e9ger de la pluie et de l'humidit\u00e9. Manipuler avec un \u00e9quipement de protection standard car la poudre peut provoquer une l\u00e9g\u00e8re irritation des yeux et du syst\u00e8me respiratoire.<\/p>","protected":false},"excerpt":{"rendered":"
