Abstract: Изобретение относится к разработке многослойных пленочных материалов, которые предназначены для упаковывания твердых сычужных сыров и служат селективным барьером для газов, образующихся внутри упаковки при созревании сыра и находящихся в окружающей среде. Пленка состоит, по крайней мере, из трех слоев: барьерного на основе ПВДХ, ограничивающего доступ О 2  в упаковку; контактного из химически инертного полимера, соприкасающегося с сыром; адгезионного слоя, расположенного между ними. Пленка изменяет свою структуру и свойства в процессе созревания упакованного в нее сыра: молочно-кислые бактерии уничтожают частицы наполнителя (углеводы, крахмал и/или альгинат натрия) в контактном слое пленки, который превращается в пористую структуру, что ускоряет миграцию CO 2  из упаковки в адгезионный слой, где он частично поглощается хитином; в обратном направлении становится возможной миграция биоцидов (аскорбиновая кислота, низин, лизоцим), предотвращающих микробиальную порчу сыра, это происходит на заключительном этапе созревания, когда жизнедеятельность молочно-кислых бактерий снижается и биоциды влияют на них незначительно. Пленка работает как активный упаковочный материал, структура и свойства которого регулируются протеканием микробиологических процессов созревания сыра. 2 з.п. ф-лы, 1 табл.
