The study examined the impact of a protein-fat emulsion (PFE) derived from turkey skin and green buckwheat flour on the quality of cooked sausages. The aim was to investigate how the addition of PFE affects various characteristics of the sausage. The experiments demonstrated that adding PFE up to 30% while stirring for up to 8 minutes at 10°C improved the sausage structure. This was evidenced by an increase in pH values to 6.5, water binding capacity to 71.2%, and ultimate shear stress to 321.86 Pa. It was observed that stuffing temperature and mixing time influenced pH, water binding capacity, and ultimate shear stress. The study identified the optimal production conditions and determined the maximum amount of PFE that can be added to sausages. Additionally, it was found that green buckwheat flour enhances the structure of the minced meat, raises pH, and increases water-binding capacity. Furthermore, PFE was noted to improve the appearance and flavor characteristics of the sausages.

The present article studies the influence of the smoking on the content and quantity of PAH with toxic action in dry fermented and smoked meat sausages. The results obtained demonstrate that higher quantities of accumulation of benzo/a/pyrene /BAP/ and dibenzo(а,I)-pyrene are found in samples of raw- fermented and smoked sausage „Petrohan” in comparison with flat sausage ‘Smyadovska’ samples. We consider that the use of artificial casings ‘fibrous’ in the production of raw-fermented and smoked meat sausages is an effective method for significant reduction in the content of polycyclic aromatic hydrocarbons in final products in comparison to those stuffed in natural sausage casings.
