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.
