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

Le dihydrog\u00e8ne pyrophosphate disodique est une poudre cristalline blanche ou un mat\u00e9riau granulaire avec une bonne solubilit\u00e9 dans l'eau. Il sert d'acidifiant, de tampon et d'agent de levage dans les applications alimentaires. Le compos\u00e9 est hygroscopique et stable dans des conditions normales, mais il se d\u00e9compose \u00e0 la chaleur pour former des polyphosphates de sodium. Il pr\u00e9sente des propri\u00e9t\u00e9s ch\u00e9latrices et r\u00e9agit avec les ions m\u00e9talliques, ce qui le rend utile dans divers processus industriels.<\/p>\n

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

Il est utilis\u00e9 comme agent de fermentation rapide, am\u00e9liorateur de qualit\u00e9, agent de levage, tampon, agent ch\u00e9lateur, agent r\u00e9hydratant et adh\u00e9sif dans l'industrie alimentaire. Le composant acide utilis\u00e9 dans la synth\u00e8se des agents levants pour le pain, les p\u00e2tisseries, etc., a un temps de production de CO2 relativement long. Il convient aux aliments cuits par fusion \u00e0 faible teneur en humidit\u00e9. Lorsqu'il est compos\u00e9 avec d'autres phosphates, il peut \u00eatre utilis\u00e9 comme agent de r\u00e9tention d'eau dans la transformation du fromage, du luncheon meat, du jambon, des produits \u00e0 base de viande et des produits aquatiques, ainsi que comme agent de r\u00e9hydratation dans les nouilles instantan\u00e9es.<\/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 sacs en papier multi-parois de 50 lb rev\u00eatus de plastique. Le stockage doit se faire dans un endroit frais, sec et bien ventil\u00e9, \u00e0 l'abri de l'humidit\u00e9 et des mati\u00e8res incompatibles. Les conteneurs doivent \u00eatre maintenus herm\u00e9tiquement ferm\u00e9s pour \u00e9viter l'absorption de l'humidit\u00e9 atmosph\u00e9rique. Dans des conditions de stockage appropri\u00e9es, la dur\u00e9e de conservation est de 24 mois. Le produit doit \u00eatre manipul\u00e9 avec pr\u00e9caution afin d'\u00e9viter la formation de poussi\u00e8res, et un \u00e9quipement de protection individuelle appropri\u00e9 doit \u00eatre port\u00e9 pendant la manipulation afin d'\u00e9viter toute irritation des yeux ou des voies respiratoires.<\/p>","protected":false},"excerpt":{"rendered":"
