1. Propiedad del producto<\/b><\/strong><\/h4>\n

El pirofosfato s\u00f3dico de calidad alimentaria es un polvo cristalino blanco o un s\u00f3lido granular, muy soluble en agua pero insoluble en alcohol. Tiene un pH fuertemente alcalino (9,9-10,7 en soluci\u00f3n de 10 g\/L) y act\u00faa como agente quelante de iones met\u00e1licos. La forma anhidra funde a 880\u00b0C, mientras que el decahidrato pierde agua a 100\u00b0C. Es higrosc\u00f3pico, absorbe la humedad del aire y se hidroliza a fosfato dis\u00f3dico cuando se hierve en agua.<\/p>\n

3. \u00c1mbito de aplicaci\u00f3n y uso<\/b><\/strong><\/h4>\n

Como aditivo alimentario, act\u00faa como mejorador de la calidad. En productos c\u00e1rnicos, retiene la humedad, mejora la ternura y la jugosidad. En el marisco, evita la decoloraci\u00f3n. Se utiliza en productos l\u00e1cteos para estabilizar emulsiones y en productos horneados para mejorar la textura. Tambi\u00e9n funciona como secuestrante en bebidas, con niveles de uso generalmente de 0,05% - 0,5%, siguiendo la normativa sobre aditivos alimentarios.<\/p>\n

<\/h3>\n

4. Embalaje y almacenamiento<\/b><\/strong><\/h4>\n

Envasado en bolsas tejidas forradas de polietileno, bolsas de papel o bolsas de pl\u00e1stico compuestas, con pesos netos comunes como 25kg\/50kg. Almacenar en un almac\u00e9n fresco, seco y ventilado. Evitar la humedad, la luz solar directa y el contacto con \u00e1cidos. Mant\u00e9ngase sellado para evitar el apelmazamiento y el deterioro de la calidad. La vida \u00fatil es de unos 24 meses en condiciones de almacenamiento adecuadas.<\/p>","protected":false},"excerpt":{"rendered":"
