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

L'isoascorbate de sodium est un granule ou une poudre cristalline blanche \u00e0 blanc jaun\u00e2tre, inodore, au go\u00fbt l\u00e9g\u00e8rement sal\u00e9. Il se d\u00e9compose au-dessus de 200\u2103 et est assez stable lorsqu'il est expos\u00e9 \u00e0 l'air \u00e0 l'\u00e9tat sec. Cependant, dans une solution hydrosoluble de Chemicalbook, l'oxydation se produit en pr\u00e9sence d'air, de m\u00e9tal, de chaleur ou de lumi\u00e8re. Il est facilement soluble dans l'eau \u00e0 55g\/100ml et presque insoluble dans l'\u00e9thanol. Le PH d'une solution aqueuse de 2% est compris entre 6,5 et 8,0.<\/p>\n

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

L'\u00e9rythorbate de sodium est largement utilis\u00e9 comme antioxydant alimentaire dans la viande (0,5 g\/kg), les conserves (1,0 g\/kg) et les boissons (0,15 g\/kg) pour pr\u00e9venir l'oxydation, conserver la couleur et inhiber la formation de nitrosamines38. Dans les boissons (jus, bi\u00e8re, vin), il emp\u00eache le brunissement et les mauvais go\u00fbts. Pour les fruits de mer congel\u00e9s, il est appliqu\u00e9 par trempage de 0,1-0,6% avant la cong\u00e9lation. Il est \u00e9galement utilis\u00e9 comme antioxydant dans les produits de boulangerie (0,2 g\/kg) et les cosm\u00e9tiques (\u22641,5% dans les soins de la peau)6. Contrairement \u00e0 la vitamine C, il n'a pas d'activit\u00e9 vitaminique mais se transforme en VC in vivo sans bloquer l'absorption\u3002.<\/p>\n

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

Emball\u00e9 dans des sacs de 25 kg rev\u00eatus de poly\u00e9thyl\u00e8ne ou dans des f\u00fbts en fibre pour \u00e9viter l'humidit\u00e9. Pour les petites quantit\u00e9s, utiliser des sacs scell\u00e9s en HDPE\/Al-foil510. Stocker dans un endroit frais, sec et sombre (<25\u00b0C, humidit\u00e9 <60%) \u00e0 l'abri des m\u00e9taux et des agents oxydants. La dur\u00e9e de conservation est de 24 mois si le produit n'est pas ouvert39. Pour le transport, \u00e9viter la chaleur et la lumi\u00e8re directe du soleil. Les produits d\u00e9compos\u00e9s (jaunissement\/odeur d'ammoniac) doivent \u00eatre jet\u00e9s. Le stockage industriel en vrac n\u00e9cessite des conteneurs rinc\u00e9s \u00e0 l'azote pour minimiser l'oxydation. Etiqueter comme non dangereux mais assurer une ventilation en raison de la lib\u00e9ration potentielle d'ammoniac lors de la d\u00e9gradation.<\/p>","protected":false},"excerpt":{"rendered":"
