Применение азота в пищевой упаковке
Application of nitrogen in food packaging
Nitrogen is an ideal inert gas and has a special effect in food packaging: it does not react with food and is not absorbed by food. It can reduce the oxygen content in the package and greatly inhibit the growth and reproduction of microorganisms such as bacteria and mold, and slow down the food. Oxidative deterioration and decay, thus keeping food fresh.
At present, nitrogen-filled packaging is rapidly replacing traditional vacuum packaging. It has been used in fried potato chips and french fries, oil-cooked food, etc. It is loved by consumers, especially children and young people. Nitrogen-filled packaging is expected to be used in more foods package.
При применении азота необходимо обратить внимание на чистоту и качество азота. Чистота азота, отделенного от сжатого воздуха мембранным разделением или адсорбцией при переменном давлении, может достигать более 99,9%. Чистота азота, используемого в пищевой упаковке, должна достигать уровня чистого азота (то есть уровня безопасности).
