Biotechnological methods to improve the quality and safety of milk

The foremost task of milk producers and processors is to prolong the shelf life of dairy products. One of the high-tech and innovative ways to address this issue is to suppress the growth of undesirable microorganisms. EMR milk treatment is proposed as one of such promising methods of product exposure in order to reduce the total microbial count, improve the milk’s chemical composition, and, ultimately, improve the quality and safety of milk and dairy products. The requirements of regulatory documents for the safety of milk and dairy products prohibit the direct introduction of preservatives into milk. In this regard, it is advisable to look for ways to use preservatives in packaging materials’ composition while observing the safety of the packaging itself. The purpose of our study was to identify the effect of electromagnetic treatment and preservatives, both direct application and in the composition of polyethylene packaging, on the physicochemical and microbiological parameters of milk at various storage temperatures. It was established that preservative’s introduction into the packaging film did not affect the chemical parameters of milk; the content of lactic acid bacteria in the product after a day of storage in modified polyethylene amounted to 1.4x106 CFU/cm3, while their number amounted 8.1x106 CFU/cm3 when stored in glass packaging.
