Company Reaserches Regarding Time and Insurance of Shelf-Life of Carcass, Cut Pieces and Chicken Organs

The paper aims to study the shelf-life of the housing, cut up pieces and chicken organs in a company slaughterhouseduring the summer. The hybrid is Ross 308. Quality samples, taken randomly during the production process fromvarious parts, was studied by means of specific laboratory from microbiological point of view (determination ofSalmonella and E.coli, NTG), organoleptical and physico-chemical (easily hydrolyzable nitrogen and Kreissreaction) during the eight days, until they exceeded the admited limits. Temperatures measured in depth of theproducts of the experiment exceeded the upper limit allowed by 3-4 degrees in the carcasse and 8-10 degrees inorgans. In terms of NTG in the liver they started to decrease in the third day of storage,in the gizzard and heart,there is a continuing increase in values during the entire experiment. This, like the gizzard increase in nitrogen value,although values range, may be a consequence of high temperatures packing and refrigeration products very slow.Storage conditions experienced cyclical deviations from the optimum temperature due to icing phenomenon ofevaporators. As a technical solution for evenly temperature during storage, it may be suggested purchasing a backuprefrigerating space. From the organoleptical point of view, all products undergo changes untill the sixth day, whichrecommends the establishment of shelf-life to this day. Microbiological and physico-chemical exceeding limitsoccurs on days seven and eight. The results, in addition to purely commercial usefulness can be considered abarometer of the correct application of technology to slaughter, hygienic production and the storage conditions ofgoods.
