摘要
FIELD: chemistry.;SUBSTANCE: method includes preparing a mixture of microcrystalline cellulose hydrogel, polyvinyl alcohol, ethyl alcohol, glycerine and quercetin, while observing the sequence of adding components to the composite mass and step-by-step homogenisation. The obtained composite can be used as a base for producing materials with different properties by adding different additives or is subjected to an additional drying step to obtain a film which has an integral structure, is capable of absorbing moisture, freezes at temperature of up -18°C without loss of properties, has the same strength as polyethylene films, has no spontaneous deformation, is biodegradable in natural conditions and has improved antioxidant properties.;EFFECT: product is environmentally safe and can be used in protecting food products from spoiling and prolongs shelf life of food products containing different types of fats.;2 cl
