Influence of modified atmospheric package size and gas composition for safety and quality indicators of fresh poltry

Academic supervisor: lecturer dr. Anita Stepankevičienė. The aim of this final coursework is to analise the infuence of modified atmospheric package size, gas compositions ant wuality indicators of fresh chicken. Main tasks: To evaluate the microbiological pollution of the production of fresh chicken products during technological processes and its influence on the quality of products. Select the most suitable mixture of modified atmospheric gas for packaging fresh chicken products. To evaluate the influence of packaging containers of different heights on the changes of the modified atmosphere gas concentration during the storage of the products. Evaluate the liquid loss of chicken fillets depending on the storage position of the packaging container. Methodology and organization of the study: During the work, a general scheme for determining the number of bacteria and the number of E. inches and cutting lines were determined from the materials with the best packaging and terms of use. The rationale / physical properties of the evaluation products and the baseboards for changes in gas concentration are the highest grade of containers for the final product and for which gas composition are most suitable. The largest natural liquid formation clock. Data processing was performed using MS Excel software. The significance performer may use SPSS software. Results obtained: The study found that the total number of bacteria in the slaughter and cutting technology in the plant does not exceed 106 CFU/g. It has been established that different products require containers of different heights, in order to obtain the longest shelf life of the product, the most suitable packaging is made of polyester, the products must be kept in a horizontal position. The most suitable gas mixture with the composition of CO2 - 20%, O2 - 30%, N2 - 50% was selected
