The bachelor thesis examines the impact of salt reduction on the sensory quality of liver pâté. The aim of the thesis is to create a sensorially acceptable pâté, in which a portion of the added salt will be replaced with potassium chloride. The theoretical part describes the composition and properties of meat, ingredients used in pâté production, and the technological process of its manufacture. Furthermore, the theoretical part elaborates on the conditions and methods of sensory analysis and sensory evaluation of pâté. The literature review also includes a description of the ICP-OES technique. The experimental part deals with the preparation of samples for sensory analysis, optimization of salt in the basic recipe, and evaluation of heat treatment. Finally, the total concentration of sodium and potassium in the individual samples was measured using ICP-OES. The results of the sensory analysis showed that the optimal salt content in the pâté is 1.09 wt. %.This content was partially replaced by KCl. It was found that a 20–40% substitution has no significant impact on the sensory properties of the product. For higher substitution, the addition of L-arginine was necessary, which positively influenced the overall perception of the pâté.
