ensayos en laboratorio.<\/p>\n<p>El control de calidad es lo que diferencia dos productos similares, lo que garantiza al cliente que el producto est\u00e1 correcto y que es comestible.<\/p>\n<p>El control de calidad en los alimentos es la utilizaci\u00f3n de par\u00e1metros f\u00edsicos, qu\u00edmicos, microbiol\u00f3gicos, nutricionales y sensoriales para lograr que un alimento sea sano y nutricional.<\/p>\n<p>Intervienen en estas propiedades de los alimentos atributos espec\u00edficos, analizados mediante m\u00e9todos que pueden ser:<\/p>\n<ul>\n<li>Subjetivos: Aspecto del alimento, olor, gusto y sensaciones t\u00e1ctiles.<\/li>\n<li>Objetivos (F\u00edsicos, qu\u00edmicos, microsc\u00f3picos y microbiol\u00f3gicos)<\/li>\n<li>Otros (Biol\u00f3gicos y

instrumentales:<\/strong> Opticos, los at\u00f3micos para la determinaci\u00f3n de metales y las t\u00e9cnicas moleculares (UV-Visible), para determinar compuestos org\u00e1nicos; Electroqu\u00edmicos, potenciom\u00e9tricos(electrodos selectivos) o valoraciones potenciometricas; cromatogr\u00e1ficos(Gaseosa y L\u00edquida) La cromatograf\u00eda de gases para la
