Study of properties of bioactive packaging film components

The article reveals the aggregate and complex indicators of the quality of innovative packaging material. It should be safe, environmentally friendly, functional, ergonomic, and have informational expressiveness. At the same time, packaging is protection, hygienic, chemical reliability, rational form, safety of use, biodegradation. The ingredient composition of the bioactive film has been selected, which does not interact with the internal microflora, does not change the taste, smell, color, aroma of the packaged product, does not cause migration of material elements into the product. The biofilm was based on sodium alginate (an additive permitted for use in food) and the filtrate of the microbial association of kefir fungi. Studies of co-cultivation of the microbial association of kefir fungi and cells of the sanitary-indicative (E. coli), opportunistic microflora - (Ent.aerogenes) revealed an antagonistic effect. Microbial cells of the association of kefir fungi inhibited the development of E. coli and Ent.aerogenes. The filtrate of the microbial association of kefir fungi will ensure the resistance of the bio-active film to the accompanying microflora, which is mainly represented by sanitary-indicative microorganisms.
