Nitr\u00f3geno l\u00edquido<\/h1>\n

El nitr\u00f3geno l\u00edquido hierve a \u2212196 \u00b0C a presi\u00f3n atmosf\u00e9rica. Vertido sobre una preparaci\u00f3n, la congela en pocos segundos.<\/p>\n

El helado estempor\u00e1neo se prepara vertiendo nitr\u00f3geno l\u00edquido directamente sobre la mezcla de nata, az\u00facar y aromas: se congela al instante, ante los comensales. La estructura ultrafina se funde antes de que el fr\u00edo llegue al paladar, permitiendo percibir todo el espectro arom\u00e1tico de principio a fin. La misma t\u00e9cnica permite producir helados alcoh\u00f3licos, imposibles con la congelaci\u00f3n tradicional por el bajo punto de fusi\u00f3n del alcohol.<\/p>\n

El nitr\u00f3geno l\u00edquido tambi\u00e9n se usa para la criomolienda<\/strong>: el alimento se congela en nitr\u00f3geno y luego se muele a baja temperatura, obteniendo polvos fin\u00edsimos de productos que a temperatura ambiente no se podr\u00edan reducir a polvo \u2014 grasas, chocolate, quesos curados.<\/p>\n<\/div>\n<\/div>\n

C\u00f3mo funciona<\/h3>\n

La velocidad de enfriamiento determina el tama\u00f1o de los cristales de hielo que se forman en la preparaci\u00f3n. En la congelaci\u00f3n lenta (congelador dom\u00e9stico) los cristales crecen y rompen las membranas celulares, alterando la textura y la estructura. Con nitr\u00f3geno l\u00edquido el enfriamiento es tan r\u00e1pido que los cristales permanecen submicrosc\u00f3picos y distribuidos homog\u00e9neamente, produciendo texturas cremosas y estables imposibles de obtener con otros m\u00e9todos.<\/p>\n<\/div>\n<\/div>\n
