The aim of the work was to determine the level of dry matter, total nitrogen, and amino acids in two kinds of green dill parts (leaves or whole plants 25 cm in height) subjected to different pre-treatment before freezing (blanching or non-blanching) and stored after freezing for 12 months at temperatures of -20°C and -30°C. The leaves of dill contained more dry matter and nitrogen compounds than whole plants. Blanching reduced the content of dry matter and total nitrogen. Refrigerated storage (-20°C and 30°C) for 12 months did not change the content of dry matter and nitrogen compounds. No differences were observed between the leaves and whole plants in the content of total amino acids and sum of essential amino acids while significant differences appeared in the content of some amino acids. In comparison with the FAO/WHO standard of 1991 the level of essential amino acids was very high, lysine being a limiting amino acid.
