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

Le bicarbonate d'ammonium est une poudre cristalline blanche avec une l\u00e9g\u00e8re odeur d'ammoniac. Il est soluble dans l'eau mais se d\u00e9compose \u00e0 des temp\u00e9ratures sup\u00e9rieures \u00e0 36\u00b0C, lib\u00e9rant de l'ammoniac, du CO\u2082 et de l'eau. Il sert d'agent levant dans la boulangerie et de tampon de pH dans l'industrie. Il doit \u00eatre stock\u00e9 dans des conditions fra\u00eeches et s\u00e8ches pour \u00e9viter une d\u00e9composition pr\u00e9matur\u00e9e.<\/p>\n

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

Le bicarbonate d'ammonium est principalement utilis\u00e9 comme agent levant dans les produits de boulangerie (par exemple, les biscuits, les crackers) en raison de sa d\u00e9composition en gaz. Il sert \u00e9galement de source d'azote dans les engrais, d'agent ignifuge et de r\u00e9gulateur de pH dans les produits pharmaceutiques et les textiles. Dans les aliments (E503), il \u00e9vite les arri\u00e8re-go\u00fbts m\u00e9talliques par rapport au bicarbonate de soude. Cependant, il laisse une odeur d'ammoniac, ce qui le rend inadapt\u00e9 aux produits humides. Les utilisations industrielles comprennent la production de colorants et l'\u00e9maillage des c\u00e9ramiques. Une manipulation s\u00fbre est essentielle pour \u00e9viter l'inhalation de fum\u00e9es d'ammoniac. Le dosage d\u00e9pend de l'application, typiquement 1-2% en boulangerie.<\/p>\n

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

Le bicarbonate d'ammonium est conditionn\u00e9 dans des sacs tiss\u00e9s de 25\/50 kg en poly\u00e9thyl\u00e8ne ou dans des f\u00fbts en fibre pour \u00e9viter l'absorption d'humidit\u00e9. Pour les petites quantit\u00e9s, utiliser des sacs HDPE scell\u00e9s. Stocker dans un endroit frais, sec et bien ventil\u00e9, \u00e0 une temp\u00e9rature inf\u00e9rieure \u00e0 25\u00b0C, \u00e0 l'abri de la chaleur et de l'humidit\u00e9. \u00c9viter le contact avec les acides pour \u00e9viter une d\u00e9composition rapide. La dur\u00e9e de conservation est de 12 \u00e0 24 mois si le produit est stock\u00e9 correctement. Garder les conteneurs herm\u00e9tiquement ferm\u00e9s pour minimiser le d\u00e9gagement d'ammoniac. Pour le stockage industriel en vrac, utiliser des silos \u00e9tanches avec des d\u00e9shydratants. Le produit d\u00e9compos\u00e9 (forte odeur d'ammoniac) doit \u00eatre \u00e9limin\u00e9. Transporter comme une marchandise non dangereuse en veillant \u00e0 la ventilation.<\/p>","protected":false},"excerpt":{"rendered":"
