Descripción de los productos: Nitrito de sodio, N.º CAS 7632-00-0
El nitrito de sodio presenta similitudes con el nitrato de sodio, especialmente en su nomenclatura y usos prácticos. En la industria alimentaria, ambos compuestos funcionan como conservantes y se añaden comúnmente a productos cárnicos procesados como la salami, los hot dogs y el beicon para prolongar su vida útil. Químicamente, el nitrito de sodio puede producirse mediante diversas reacciones sintéticas, y cada una de ellas se basa en el proceso de reducción del nitrato de sodio. A nivel industrial, la principal vía de producción implica disolver los óxidos de nitrógeno en soluciones acuosas de carbonato de sodio u hidróxido de sodio.

Aplicación del producto: Nitrito de sodio, N.º CAS 7632-00-0
El nitrito de sodio, clasificado como la sal del ácido nitroso, cumple dos funciones esenciales: inhibe el crecimiento microbiano (como agente antimicrobiano) y prolonga la vida útil de los productos (como conservante). Sus formas físicas incluyen un polvo granular de color amarillento pálido, así como masas o barras casi blancas e opacas. Una propiedad destacable es su deliquescencia, es decir, su capacidad para absorber humedad del aire circundante. En cuanto a su solubilidad, 1 gramo de nitrito de sodio se disuelve en 1,5 mililitros de agua. En el procesamiento de la carne, se utiliza específicamente durante el curado para estabilizar su color y realzar su sabor característico. Más información se puede encontrar en la sección dedicada a los «nitritos».
