1\u3001Propri\u00e9t\u00e9 du produit<\/h4>\n

L'hydroxyde de sodium de qualit\u00e9 alimentaire est un solide blanc, inodore (paillettes, granul\u00e9s ou poudre) tr\u00e8s corrosif et hygroscopique. Il se dissout exothermiquement dans l'eau, formant une solution alcaline forte. Il r\u00e9agit avec les acides, les graisses et les m\u00e9taux. Utilis\u00e9 dans l'industrie alimentaire, il doit r\u00e9pondre \u00e0 des normes de puret\u00e9 strictes afin de garantir sa s\u00e9curit\u00e9 pour la consommation humaine.<\/p>\n

\n3\u3001Champ d'application et utilisation<\/h4>\n

L'hydroxyde de sodium de qualit\u00e9 alimentaire est largement utilis\u00e9 dans la transformation des aliments, notamment pour peler les fruits\/l\u00e9gumes, neutraliser les acides dans les huiles comestibles et nettoyer les conteneurs alimentaires. Il agit comme r\u00e9gulateur de pH dans les boissons et la modification de l'amidon. Dans la transformation des fruits de mer, il r\u00e9hydrate les produits s\u00e9ch\u00e9s, tandis qu'en boulangerie, il am\u00e9liore le brunissement (par exemple, les bretzels). Il contribue \u00e9galement \u00e0 la transformation du cacao et \u00e0 la production de caramel. Un contr\u00f4le strict du dosage est n\u00e9cessaire (g\u00e9n\u00e9ralement 0,1-2%) pour \u00e9viter l'alcalinit\u00e9 r\u00e9siduelle. Les utilisations industrielles comprennent les produits pharmaceutiques et les cosm\u00e9tiques, mais les applications alimentaires n\u00e9cessitent un NaOH de haute puret\u00e9 avec un minimum de m\u00e9taux lourds.<\/p>\n

4\u3001Emballage et stockage<\/h4>\n

L'hydroxyde de sodium de qualit\u00e9 alimentaire est conditionn\u00e9 dans des sacs tiss\u00e9s en poly\u00e9thyl\u00e8ne de 25 kg ou dans des f\u00fbts en HDPE pour \u00e9viter l'absorption d'humidit\u00e9. Pour les petites quantit\u00e9s, on utilise des bouteilles en plastique scell\u00e9es. Le stockage doit se faire dans un endroit frais, sec et ventil\u00e9 (<25\u00b0C), \u00e0 l'\u00e9cart des acides et des m\u00e9taux. Les conteneurs doivent \u00eatre herm\u00e9tiques pour \u00e9viter l'absorption de CO\u2082, qui forme du carbonate de sodium. La dur\u00e9e de conservation est de 2 ans si le produit est stock\u00e9 correctement. Le transport n\u00e9cessite un emballage r\u00e9sistant \u00e0 la corrosion avec des \u00e9tiquettes "Corrosif". Les d\u00e9versements doivent \u00eatre neutralis\u00e9s avec des acides faibles (par exemple, du vinaigre). Les travailleurs doivent porter des gants et des lunettes de protection en raison de la forte corrosivit\u00e9 du produit.<\/p>","protected":false},"excerpt":{"rendered":"
