1\u3001Propiedades del producto<\/h4>\n

El hidr\u00f3xido de sodio de calidad alimentaria es un s\u00f3lido blanco e inodoro (copos, gr\u00e1nulos o polvo) altamente corrosivo e higrosc\u00f3pico. Se disuelve exot\u00e9rmicamente en agua, formando una soluci\u00f3n fuertemente alcalina. Reacciona con \u00e1cidos, grasas y metales. Utilizado en la elaboraci\u00f3n de alimentos, debe cumplir estrictas normas de pureza para garantizar su seguridad para el consumo humano.<\/p>\n

\n3. \u00c1mbito de aplicaci\u00f3n y uso<\/h4>\n

El hidr\u00f3xido de sodio de calidad alimentaria se utiliza ampliamente en el procesado de alimentos, incluido el pelado de frutas\/verduras, la neutralizaci\u00f3n de \u00e1cidos en aceites comestibles y la limpieza de envases de alimentos. Act\u00faa como regulador del pH en bebidas y en la modificaci\u00f3n del almid\u00f3n. En el procesado de marisco, rehidrata los productos secos, mientras que en panader\u00eda, mejora el dorado (p. ej., pretzels). Tambi\u00e9n ayuda en el procesado del cacao y la producci\u00f3n de colorante caramelo. Se requiere un estricto control de la dosificaci\u00f3n (normalmente 0,1-2%) para evitar la alcalinidad residual. Los usos industriales incluyen productos farmac\u00e9uticos y cosm\u00e9ticos, pero las aplicaciones alimentarias requieren NaOH de gran pureza con un m\u00ednimo de metales pesados.<\/p>\n

<\/h4>\n

4\u3001Embalaje y almacenamiento<\/h4>\n

El hidr\u00f3xido de sodio de calidad alimentaria se envasa en bolsas tejidas forradas de polietileno de 25 kg o en bidones de HDPE para evitar la absorci\u00f3n de humedad. Las cantidades peque\u00f1as se envasan en botellas de pl\u00e1stico selladas. El almacenamiento debe realizarse en un lugar fresco, seco y ventilado (<25\u00b0C), lejos de \u00e1cidos y metales. Los recipientes deben ser herm\u00e9ticos para evitar la absorci\u00f3n de CO\u2082, que forma carbonato s\u00f3dico. La vida \u00fatil es de 2 a\u00f1os si se almacena adecuadamente. El transporte requiere envases resistentes a la corrosi\u00f3n con etiquetas de "Corrosivo". Los derrames deben neutralizarse con \u00e1cidos d\u00e9biles (por ejemplo, vinagre). Los trabajadores deben llevar guantes y gafas debido a su fuerte corrosividad<\/p>","protected":false},"excerpt":{"rendered":"
