Peculiarities of the chemical composition of dried leaves of Aegopodium podagraria and determination of the possibility of its use in the production of functional food products

Relevance . Aegopodium podagraria L. is a promising source of biologically active substances for use in functional and specialized food systems. Methods . The objects of the study were ordinary dried leaves with a moisture content of 8.5%. Dried Aegopodium podagraria is prepared from leaves of goutweed, grown in the conditions of Kuzbass. When carrying out the research, the following test methods were used: the mass fraction of iron was determined according to GOST 26928-86 by the colorimetric method, the mass fraction of phosphorus according to methodological instructions 4.1.3217-14, the mass fraction of calcium according to the “Guide to methods for analyzing the quality and safety of food products” (Skurikhin I.M., Tutelyan V.A. Moscow, 1998), vitamin C content according to GOST 24556-89, mass fraction of dietary fiber according to GOST R 54014-2010 (enzymatic-gravimetric method), mass fraction of protein according to GOST 54607.7-2016 (Kjeldahl method), mass fraction of ash according to GOST 5901-2014, mass fraction of ash according to GOST 5901-2014, mass concentration of zinc and copper according to GOST 33842-2016. Results . The article is the first to show the high content of ordinary ascorbic acid in dried leaves of Aegopodium podagraria , the proportion of which is 168 mg / 100 g, which allows recommending the ascorbic acid as an ingredient with increased antioxidant activity. According to research, the total amount of minerals is 18.65%. The high iron content should be noted: 118.9 ± 33.3 mg / 100 g, which is more than 600% of the daily intake. Of the macroelements, the content of phosphorus (144.8 ± 40.5) and calcium (1134.8 ± 158.9) is high, which satisfies the daily physiological norm of their consumption by 12% and 94%, respectively. The content of copper and zinc does not exceed their maximum permissible concentration (5 mg/kg), which indicates the safety of use in food production technologies. The data obtained make it possible to calculate the percentage of the addition of dried Aegopodium podagraria into product formulations to obtain enriched or functional products.
