In today’s world diseases of alimentary etiology are common. They occur when there is insufficient intake of important essential substances, that include amino acids. Lack of essential amino acids can lead to serious disruptions in vital functions of body. Therefore, development of food products, balanced in amino acid composition, is the most important technological task of food production. Semi-finished products are one of the food groups, that in great demand among the general population. Therefore, these foods are often enriched with disease-preventing nutrients. In addition, creation of products with specified properties allows to reduce cost price due to introducing cheap plant materials into the product. The article provides data on effect of milk thistle powder and flaxseed flour on amino acid composition of meat stuffed chopped semi-finished products. Calculation of parameters of amino acid score and amino acid index in the products is presented. The results of organoleptic evaluation of experimental samples are also presented. During the study, mass fractions of proteins, fats and carbohydrates were determined. Organoleptic evaluation was carried out and energy value of each sample was calculated. Based on obtained data, a comparison was made between control sample and experimental samples in all parameters. In addition, it was found that a test sample containing milk thistle powder is capable of increasing protein content, as well as increasing amino acid index and amino acid score of the product.
