\u4e09\uff0e\u00c1mbito de aplicaci\u00f3n y uso<\/h4>\n

El propilenglicol alimentario es un l\u00edquido viscoso incoloro, transparente y no precipitante. Se utiliza ampliamente en la industria alimentaria. Seg\u00fan las normas nacionales, est\u00e1 aprobado como aditivo alimentario y se utiliza principalmente como estabilizador, emulsionante y disolvente. Es habitual encontrarlo en productos como el pan y la nata. El propilenglicol tiene buenas propiedades higrosc\u00f3picas y anticongelantes, que pueden mantener la humedad y la frescura de los alimentos. Adem\u00e1s, tambi\u00e9n puede utilizarse en la elaboraci\u00f3n de cerveza y la extracci\u00f3n de sustancias arom\u00e1ticas.<\/p>\n

 <\/p>\n

\u56db\uff0eEmbalaje y almacenamiento<\/h4>\n

El producto se envasa en bidones de pl\u00e1stico, con una especificaci\u00f3n de 215 kg por bid\u00f3n, o de acuerdo con las especificaciones de envasado solicitadas por el cliente.<\/p>\n

Es extremadamente estable a temperatura ambiente, pero se oxida cuando se expone a altas temperaturas (superiores a 280\u2103); cuando se mezcla con etanol 95% o agua, tiene estabilidad qu\u00edmica; se puede esterilizar por prensado t\u00e9rmico o esterilizaci\u00f3n por filtraci\u00f3n. El propilenglicol es higrosc\u00f3pico y debe almacenarse en un lugar fresco y seco, en un recipiente a prueba de luz y sellado.<\/p>\n
