The review highlights the role of antioxidants in minimizing oxidative changes that may adversely affect the quality of meat and meat products, cause changes in their testing and nutritional properties. This applies particularly to the use of natural antioxidants based on plant extracts, which can be a good alternative to traditional antioxidants, thanks to its high content of phenolic compounds. From the literature it can be concluded that extracts of broccoli, rosemary, mint, grape seed and green tea have a significant antioxidant effect in the meat products. Broccoli and grape seeds extracts have a pronounced antioxidant activity compared to synthetic antioxidants. Laminarin/fucoidan extracts have prooxidative effect on lipid perperoxidation. Essential oils of L. angustifolia and M. piperita effectively inhibit E. coli O157:H7 and S. aureus in the chopped beef meat. The alcoholic extract of the dried leaves of oregano has the highest content of total phenols, however, does not exhibit antioxidant properties. The extracts of rosemary, orange, lemon, mint and curry have positive effect on the color of the meat products. When choosing natural antioxidants it is necessary to pay attention to their impact on testing and qualitative characteristics of these food products.

We present a study into bacteriostatic effects achieved by re­pasteurization at a temperature of 85–90 °C for 20 minutes in the presence of an oxygen absorber. The applied treatment method makes it possible, on day 94 of storage, to obtain the level of contamination of microorganisms, comparable to the background microbiological contamination of sausages, for the sausages produced without pasteurization.The study confirmed the effectiveness of protective barrier properties of multilayer polymeric materials manufactured by LLC Sirius Extruzhen (Ukraine) for the storage of boiled sausages for up to 26 days. We established the possibility of storing sausages for 35 days based on the obtained data on the stability of microbiological indicators and compliance with the requirements to organoleptic indicators.The study presented ways to achieve the shelf life of cooked sausages twice longer than the typical, recommended for sausages with re­pasteurization. We obtained the results for sausages exposed to re­pasteurization at a temperature of 85–90 °C for 15–20 minutes. We packaged the examined samples at the thermoforming lines “Multivac” (Germany) and “Webomatic” (Germany). We performed the pasteurization of products at the “Fessman” (Germany) universal heat chamber.We confirmed the possibility of combination of protein stabilizers and animal proteins based on pig skin, dairy products, and spices in the formulations of samples of pasteurized sausages made from beef, pork, poultry meat, in particular, poultry meat of mechanical boning. In the study, we established that the grade of boiled sausages does not produce a significant effect on the shelf life of sausages when applying re­pasteurization together with an oxygen absorber

Nepeta cataria var. citriodora Beck. (catmints) is a source industrial production of citral and attractive raw material for food industry and cooking. Aerial part of Nepeta are characterized by high antimicrobial activity and fungicidal action against mold fungi, used in folk medicine, as ingredient in recipes for sausages, liqueurs and soft drinks, vegetable and fruit canned food, in the manufacture of vermouth. Ukrainian variety 'Melody' was created specifically for growing in the Forest-Steppe zone, and variety 'Peremozhets' – in the Steppe zone. Data on the yield aerial part and essential oil Nepeta was determined. The dry aerial part of plants N. cataria we used to create a dry spicy mixture for sweet dessert dishes. Quantitative content and qualitative composition of essential oil of plants by organs and phases of vegetation are presented in the article. In our research we used essential oils obtained by hydro distillation procedure for 2 h using Clevendger-type apparatus from the flowering parts of plants N. cataria 'Peremozhets' and 'Melody'. Investigate of components was carried out by high effective gas chromatography with HP 6890 chromatograph coupled with HP 5972 mass selective detector. The most abundant components of Nepeta essential oil was citral, geraniol, as well as nerol, citronellol, citronellal, carvacrol, camphor, eugenol. We proposed fractional distillation of essential oils to obtain a line of flavors with stable sensory and physicochemical indicators for food industry. The separation of essential oils into fractions was carried out on a pilot installation of fractional distillation DFD (Device of Fractional Distillation). Calculations of parameters controlled dispersal of essential oils (residual pressure, temperature regimes, number of theoretical plates, reflux number) were carried out. During fractionation of essential oil of N. cataria four fractions were obtained with a content of 96 ±0.5% to the total mass of samples. Sensory and physicochemical analysis of aromatic fractions announced them as promising flavours for food industry.

The use of hydrocolloids in the modern meat industry is the one of prospective directions for improving functional and technological characteristics of meat and meat products, including poultry at long storage terms. A series of concrete requirements to functional-technological, physical-chemical and organoleptic parameters is offered for canned poultry in correspondence with minimal specifications for the quality of products of an animal origin. There is presented the study of the optimization of the process of meat products sterilization using meat of chicken-broilers, quails and hydrocolloids depending on physical-chemical and organoleptic properties. The parameters of quail meat use in recipes of canned poultry meat with hydrocolloids were considered. The influence of the sterilization process on characteristics of chicken-broiler and quail meat was established. There was revealed the essential difference in the influence on functional and technological parameters of canned quail meat using hydrocolloid mixtures comparing with canned chicken-broiler meat, manifested in changes of MKC (moisture keeping capacity), plasticity and salt content in jelly. At changing sterilization regimes, there takes place the change of physical and chemical characteristics of gels that correlates with organoleptic characteristics. For providing high quality parameters of canned poultry meat and industrial sterility, sterilization regimes for canned chicken-broiler meat must be realized for containers with the volume 500 with sterilization time no more than 90 minutes. For canned quail meat the sterilization process duration must be increased to 120 min at the temperature 115 ° С.
