For today, the issue of maximum preservation of meat and meat products at all stages of their production, storage, transportation and realization does not lose its relevance. Existing ways of food products’ preservation for prevention of their microbiological damage are divided into three groups: physical, chemical and biological. The article gives an analysis of modern methods of meat and meat products’ processing. Physical (chill, freezing, super freezing, ionizing irradiation, ultraviolet irradiation, pressure processing, laser irradiation) and chemical (with the use of organic acids, trisodium phosphate, extracts of plants with bacteriostatic properties etc.) methods of meat and meat products’ preservation are characterized. The data on the methods for extension of realization term due to the use of modern packaging materials (modified atmosphere, system of ‘active packaging’ and aseptic packaging) is given. The advantages and disadvantages of each of these methods are indicated.

Abstract Spouted pouches are being increasingly used in the beverage sector. However, aseptic packaging technology used for spouted pouches requires a highly complex sterilisation and rinsing process for the packaging materials before filling. This paper deals with the pouch packaging sterilisation process used in aseptic technology. A mixture composed of vaporised hydrogen peroxide and hot sterile air is injected into the package through a sterilisation nozzle. A CFD multicomponent model in ANSYS CFX (version 14.5) has been created and validated in order to simulate the real process. Based on this model, the paper aims to minimise hydrogen peroxide consumption and optimise the sterilisation treatment of the packaging. This issue has been approached using multi-objective optimisation software applied to CFD multicomponent simulations. The most suitable nozzle position inside the pouch has been established, as well as the optimal treatment time, concentration and flow rate of the sterilising mixture.

The possible effects of hydrogen peroxide (HP) sterilization on migration from polypropylene (PP) and polyethylene (PE) food-packaging materials have been investigated. A number of indices have been used to measure any changes in polymer composition, surface characteristics and migration levels into food simulants, brought about by commercial sterilization procedures using HP. These measurements revealed that changes were limited to a slight and superficial modification of the polymer surface. The composition of the polymer and migration levels from the polymer to food simulants were not changed markedly. It is concluded that neither the nature nor the level of migration into food is likely to be influenced significantly by the aseptic-packaging process of polymer sterilization using HP.
