Abstract
This study aimed to determine the effect of technological parameters of the production of horse meat minces with the addition of protein-oil emulsion from chicken combs on the functional, technological and physicochemical indicators. Chicken combs were pre-treated with bacterial concentrate to improve their properties. Experimental approach: The ultimate shear stress and technological indicators – water holding capacity and oil holding capacity – were determined to set the optimal time for cutting raw materials. Physicochemical analyses of the meat minces were conducted. Results and conclusions: The research results have shown that the cutting time significantly affects the meat minces' rheological, functional and technological indicators. The optimum mixing time for meat minces is 6 min. Adding a protein-oil emulsion from biotechnologically processed chicken combs, cottonseed oil, and water into the minced horse meat does not significantly affect the nutritional value. Adding 15 – 20% protein-oil emulsion (POE) is recommended to get minced meat with optimal rheological parameters. Novelty and scientific contribution: The research results allow the rational use of poultry by-products.

Abstract
When slaughtering and processing poultry, large quantities of meat by-products are generated; therefore, the development of the newest methods for processing secondary raw materials is an urgent problem. Animal proteins have relevant technological applications and are also considered as a potential source of bioactive peptides. Current technologies suggested that protein substances can be isolated from meat co-products through microbial hydrolysis. The purpose of the study was to optimize the technological parameters of microbial hydrolysis of hen combs and to analyze the modification of the microstructure and properties of hydrolyzed by-products under the action of bacterial enzymes. Hen’s combs were hydrolyzed by bifidobacteria and concentrated Propionix liquid. A multifactorial experiment was used to determine the optimal conditions for the hydrolysis process. As a result of the study, multiple regression equations and response surfaces were obtained, which describe the process of hydrolysis of hen combs to identify the optimal hydrolysis parameters. Temperature, amount of bacterial concentrate and hydrolysis period are factors that have a significant impact on the degree of hydrolysis. The results of microscopic and dispersed analysis confirm the good hydrolyzability of combs due to changes in structural components and an increase in the amount of smaller protein particles.

Abstract
Germinated cereal crops are widely used in the technology of meat products, as they contain a significant amount of vitamins, minerals and protein. This study presents the formulation and processing technology of meat pate with the addition of wheat (Triticum aestivum) germ. Three treatments of 10, 15 and 20% of germinated wheat (GW) were prepared. Wheat sprouts were crushed and mixed for 6 minutes in a meat mixer together with broth, oat flour, and spices to obtain a smooth mass. This was mixed with minced meat and grinded on a cutter to obtain a more uniform finished paste that was dosed into lamister or tin containers, sterilized and stored for 2 years. This was followed by the determination of its proximate composition, water-binding capacity, and sensory analysis. Results show that the meat pate with 10% of GW in comparison with the control, contain more protein, is more nutritious with a lower fat content of 6.8% and a lower carbohydrate content of 11.3%. The results of organoleptic evaluation showed that the highest average score was for the meat pate with a recipe that contains 10% of germinated wheat, and the lowest was for the meat pate containing 20% of germinated wheat. Meat pate containing 10% of germinated wheat has a higher water-holding capacity and the optimal pH value. This study suggests that wheat can be used in appropriate formulation to improve the organoleptic quality of meat pate.
