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

L'ac\u00e9tate d'amidon (amidon ac\u00e9tyl\u00e9) est un amidon modifi\u00e9 produit en traitant l'amidon naturel (comme le ma\u00efs, la pomme de terre ou le tapioca) avec de l'anhydride ac\u00e9tique ou de l'ac\u00e9tate de vinyle. Ce processus introduit des groupes ac\u00e9tyles, ce qui am\u00e9liore sa stabilit\u00e9, sa texture et sa r\u00e9sistance aux temp\u00e9ratures \u00e9lev\u00e9es et \u00e0 la cong\u00e9lation. Il forme des gels clairs et lisses, ce qui en fait un \u00e9paississant, un stabilisateur et un liant id\u00e9al dans les produits alimentaires tels que les sauces, les repas surgel\u00e9s et les produits de boulangerie (r\u00e9glement\u00e9 en tant que E1420 dans les applications alimentaires).<\/p>\n

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

L'ac\u00e9tate d'amidon (amidon ac\u00e9tyl\u00e9) est largement utilis\u00e9 dans les industries alimentaires et non alimentaires en raison de sa stabilit\u00e9 et de sa texture am\u00e9lior\u00e9es. Dans les applications alimentaires, il sert d'\u00e9paississant, de stabilisateur et de liant dans des produits tels que les sauces, les vinaigrettes, les aliments surgel\u00e9s, les produits de boulangerie et les snacks (approuv\u00e9 en tant qu'additif alimentaire E1420). En dehors de l'alimentation, il est utilis\u00e9 dans les films biod\u00e9gradables, les rev\u00eatements de papier, les textiles, les adh\u00e9sifs et les produits pharmaceutiques pour ses propri\u00e9t\u00e9s de formation de film et de liaison.<\/p>\n

4. l'emballage et le stockage<\/h4>\n

L'ac\u00e9tate d'amidon est g\u00e9n\u00e9ralement conditionn\u00e9 dans des sacs en papier kraft multicouches de 25 kg ou dans des sacs doubl\u00e9s de poly\u00e9thyl\u00e8ne de qualit\u00e9 alimentaire pour garantir la r\u00e9sistance \u00e0 l'humidit\u00e9. Pour les commandes en vrac, il peut \u00e9galement \u00eatre fourni dans des conteneurs flexibles interm\u00e9diaires en vrac (FIBC) de 500 \u00e0 1000 kg. Le produit doit \u00eatre stock\u00e9 dans un entrep\u00f4t frais, sec et bien ventil\u00e9, \u00e0 l'abri de la lumi\u00e8re directe du soleil, \u00e0 une temp\u00e9rature inf\u00e9rieure \u00e0 25\u00b0C et \u00e0 une humidit\u00e9 relative inf\u00e9rieure \u00e0 65%. Garder les conteneurs herm\u00e9tiquement ferm\u00e9s lorsqu'ils ne sont pas utilis\u00e9s afin d'\u00e9viter l'absorption d'humidit\u00e9 et la contamination. Correctement stock\u00e9, l'ac\u00e9tate d'amidon conserve une qualit\u00e9 stable jusqu'\u00e0 24 mois \u00e0 compter de la date de production.<\/p>","protected":false},"excerpt":{"rendered":"
