Si la carne pierde su color rojo y se hace amarronada es porque la exposici\u00f3n al aire ambiental provoca que la <strong>oximioglobina <\/strong>(lo que le da el color rojo) se convierta en <strong>metamioglobina.<\/strong><\/p>\n<p style=\"text-align: justify;\">Las atm\u00f3sferas selladas retrasar\u00edan estos efectos. Un empaquetado rico en di\u00f3xido de carbono reduce el da\u00f1o bacteriol\u00f3gico, llega a quintuplicar la fecha de caducidad de los vegetales y <strong>permite que la carne mantenga su buen aspecto al menos durante 48 horas.<\/strong><\/p>\n<p style=\"text-align: justify;\">Los envasados a base de nitr\u00f3geno reducen en ennegrecimiento de los vegetales.<br \/>Para conservar pescado graso, como el arenque y la caballa, se usa una mezcla de di\u00f3xido de carbono y nitr\u00f3geno a raz\u00f3n de 60\/40.<\/p>\n<p style=\"text-align: justify;\">La pel\u00edcula transparente en la que se envuelve el producto <strong>tambi\u00e9n est\u00e1 alterada para evitar que la comida se estropee.<\/strong> Las pel\u00edculas depuradoras de etileno eliminan el gas que provoca la decoloraci\u00f3n de los vegetales verdes.<\/p>\n<table border=\"3\" cellspacing=\"0\" cellpadding=\"0\">\n<tbody>\n<tr>\n<td bgcolor=\"#3b7cff\" height=\"25\" width=\"600\" align=\"center\"><strong><a title=\"Actualidad ACCION del OZONO\"     href=\"https:\/\/www.ozono21.com\/actualidad-interna\/accion-del-ozono\/423\/\" target=\"_blank\"  rel=\"noopener noreferrer\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.ozono21.com\/blog\/wp-content\/uploads\/2014\/06\/Noticias-Relacionadas.png\" alt=\"Noticias Relacionadas\" width=\"600\" height=\"25\" border=\"0\" \/><\/a><\/strong>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p><big><strong><\/p>\n<table border=\"0\" cellspacing=\"0\" cellpadding=\"0\">\n<tbody>\n<tr>\n<td width=\"150\" height=\"150\" align=\"center\"><a title=\"Ozono para la seguridad alimentaria\" href=\"https:\/\/www.ozono21.com\/actualidad-interna\/ozono-para-seguridad-alimentaria\/68\/\"  target=\"_blank\"  rel=\"noopener noreferrer\"><img loading=\"lazy\" decoding=\"async\" alt=\"seguridad de los alimentos\" title=\"El futuro de la seguridad de los alimentos\" src=\"https:\/\/www.ozono21.com\/blog\/wp-content\/uploads\/2014\/08\/INDUSTRIA-ALIMENTOS.jpg\" width=\"150\"   height=\"140\"  border=\"0\"  \/><\/a><\/td>\n<td width=\"300\" height=\"150\" style=\"text-align: left; vertical-align: middle;\"><strong><a title=\"Ozono para la seguridad alimentaria\" href=\"https:\/\/www.ozono21.com\/actualidad-interna\/ozono-para-seguridad-alimentaria\/68\/\"  target=\"_blank\"  rel=\"noopener noreferrer\">Ozono para la seguridad alimentaria<\/a><\/strong><\/li>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p><\/strong><\/big><\/p>\n<table border=\"3\" cellspacing=\"0\" cellpadding=\"0\">\n<tbody>\n<tr>\n<td bgcolor=\"#3b7cff\" height=\"25\" width=\"600\" align=\"center\"><strong><a title=\"Videos YouTube\" target=\"_blank\"     href=\"http:\/\/www.youtube.com\/user\/ozono21\/videos?sort=p&amp;view=0&amp;flow=grid\" rel=\"noopener noreferrer\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.ozono21.com\/blog\/wp-content\/uploads\/2014\/06\/Videos-Youtube.png\" alt=\"Videos Youtube\" width=\"600\" height=\"25\" border=\"0\" \/><\/a><\/strong>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>&nbsp;<\/p>\n<p style=\"TEXT-ALIGN: center\"><iframe loading=\"lazy\" width=\"640\" height=\"480\" src=\"https:\/\/www.youtube.com\/embed\/hy4FIfaUav0\" frameborder=\"0\" allow=\"accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen><\/iframe><\/p>\n<div class=\"pvc_clear\"><\/div>\n<p id=\"pvc_stats_318\" class=\"pvc_stats total_only  \" data-element-id=\"318\" style=\"\"><i class=\"pvc-stats-icon small\" aria-hidden=\"true\"><svg aria-hidden=\"true\" focusable=\"false\" data-prefix=\"far\" data-icon=\"chart-bar\" role=\"img\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 512 512\" class=\"svg-inline--fa fa-chart-bar fa-w-16 fa-2x\"><path fill=\"currentColor\" d=\"M396.8 352h22.4c6.4 0 12.8-6.4 12.8-12.8V108.8c0-6.4-6.4-12.8-12.8-12.8h-22.4c-6.4 0-12.8 6.4-12.8 12.8v230.4c0 6.4 6.4 12.8 12.8 12.8zm-192 0h22.4c6.4 0 12.8-6.4 12.8-12.8V140.8c0-6.4-6.4-12.8-12.8-12.8h-22.4c-6.4 0-12.8 6.4-12.8 12.8v198.4c0 6.4 6.4 12.8 12.8 12.8zm96 0h22.4c6.4 0 12.8-6.4 12.8-12.8V204.8c0-6.4-6.4-12.8-12.8-12.8h-22.4c-6.4 0-12.8 6.4-12.8 12.8v134.4c0 6.4 6.4 12.8 12.8 12.8zM496 400H48V80c0-8.84-7.16-16-16-16H16C7.16 64 0 71.16 0 80v336c0 17.67 14.33 32 32 32h464c8.84 0 16-7.16 16-16v-16c0-8.84-7.16-16-16-16zm-387.2-48h22.4c6.4 0 12.8-6.4 12.8-12.8v-70.4c0-6.4-6.4-12.8-12.8-12.8h-22.4c-6.4 0-12.8 6.4-12.8 12.8v70.4c0 6.4 6.4 12.8 12.8 12.8z\" class=\"\"><\/path><\/svg><\/i> <img loading=\"lazy\" decoding=\"async\" width=\"16\" height=\"16\" alt=\"Loading\" src=\"https:\/\/www.ozono21.com\/blog\/wp-content\/plugins\/page-views-count\/ajax-loader-2x.gif\" border=0 \/><\/p>\n<div class=\"pvc_clear\"><\/div>\n","protected":false},"excerpt":{"rendered":"<p>Aunque lo neguemos, la comida entra por los ojos.
