CANNABIS INFLORESCENCES CHEMICAL COMPOSITION

The results of studies of the chemical composition of inflorescences of hemp seed variety Maria, growing in the territory of the Ermakovsky District of the Krasnoyarsk Region, are presented. The inflorescences were dried in a thermostat at a temperature of 50–60 °C to an air-dry state, crushed in a laboratory mill, and sieved on a sieve with a mesh size of 3–4 mm. An average sample was taken by the quartering method to study the chemical composition of hemp inflorescences. The protein content in the inflorescence of hemp seed was 14.369 %; fat – 4.03; sugars – 0.538; starch – 2.93; minerals – 20.71 %. The qualitative and quantitative elemental composition of inflorescences was studied. There is a high content of such minerals as calcium (206.000 g/kg), magnesium (17.880 g/kg), sodium (341.600 g/kg), potassium (14.800 mg/kg), iron (916.80 mg/kg). The results of the study of the fatty acid composition of hemp inflorescences showed that it contains essential polyunsaturated acids – linoleic (40.7799 %), alpha-linoleic (14.0285 %). The amino acid composition of the protein of cannabis inflorescences was determined. The content of essential amino acids threonine (0.5364 mg%), methionine (0.2232 mg%), tryptophan (0.0396 mg%), leucine + isoleucine (0.4196 mg%), valine (0.5074 mg%) , phenylalanine (0.6344 mg%), lysine (0.4312 mg%) was established. The content of ascorbic acid in the inflorescence of hemp seed was 0.121 %. The presence of vitamins of group B was established: B2 – 6.00 g/kg; B3 – 0.2905; B5 – 0.4587; B6 – 7.35 g/kg. Thus, inflorescences of hemp seed variety Maria contain physiologically significant components in their composition and can be a valuable source of raw materials in the development of formulations for various food products.
