Key words: ABSTRACT Proteinaceous halfProducts Quality modeling Recipe optimization Plant green mass Amino acidsThe literary data and the results of our own researches became a basis for this article to prove the possibility of solving the problem of protein deficit in diets of population by optimizing the protein component in recipes of final products. The authors proposed the modified theory to model the amino acid content for green mass of agricultural and wild plants like red and sugar beets, carrot, nettle, ramsons etc. There were established the parameters of the area of quality profile for an ideal protein in conditions that the score for all of the indispensable amino acids is equal to 1. The proposed model allows creating the composites with well-balanced amino acid content on the base of green mass half-products, which will furthermore solve the important social and economical task in the sphere of food technologies.
