FIELD: agriculture; development and production of multilayer films materials for packing of solid rennet cheeses.

SUBSTANCE: the invention is dealt with development of the multilayer film materials intended for packing of solid rennet cheeses and serve as a selective barrier to the gases formed inside a packing at a cheese maturing and stayed in the environment. The film consists at least of three layers: a barrier layer based on PVDC and limiting accessO2 into the packing; a contact layer out of chemically inert polymer contacting the cheese; an adhesion later located between them. The film changes its structure and properties in the process of maturation of the cheese packed into it: lactic acid bacteria annihilate corpuscles of the filler (carbohydrates, starch and-or sodium alginate) in the contact layer of the film of a film, which turns into a porous structure, that speeds up migration of CO2 from the packing into the adhesion layer, where it is partially absorbed by chitin; in the opposite direction migration of biocides becomes possible (an ascorbic acid, nisin, lysozyme) preventing a microbial spoilage of a cheese, this takes place at a final stage of a maturation, when the vital functions of the lactic acid bacteria is decreasing and biocides influence them insignificantly. The film acts as an active packing material, which structure and properties are regulated by the running of microbiological processes of the cheese maturation.

EFFECT: the invention ensures action of the film as an active packing material, the structure and properties of which are regulated by the running of microbiological processes of the cheese maturation.
