Introduction. Modern scientific research into the biochemical composition and medicinal value of plants makes it possible to use them as functional ingredients in food technology. The research objective was to test rose root (Rhodiola rosea L.) and scullcap (Scutellaria galericulata L.) for biologically active substances and their potential use in functional dairy products. Study objects and methods. The research featured biologically active substances (BAS) obtained from rose root and scullcap that grow in mountain areas or on rock outcrops along Siberian rivers. The BAS content was determined using high performance liquid chromatography (HPLC). The biologically active substances were screened and identified using HPLC, thin-layer chromatography (TLC), and infra-red identification (IR). The new functional products were based on whey and cottage cheese made from processed whole milk. Results and discussion. The analysis of Rhodiola rosea rhizomes and roots showed the following BAS content (mg/g): rosavin – 16.9, salidroside – 14.3, rosin – 5.04, rosarin – 2.01, and methyl gallate – 6.8. The roots of Scutellaria galericulata had the following BAS content (mg/g): scutellarein – 22.27, baicalin – 34.37, baicalein – 16.30, apigenin – 18.80, chrysin – 6.50, luteolin – 5.40, and vogonin – 3.60. Whey served as a basis for a new functional whey drink fortified with BAS isolated from Rhodiola rosea 100 mL of the drink included 50 mL of whey, 20 mL of apple juice, 0.1 mL of rose root concentrate, 3 g of sugar, 0.5 g of apple pectin, 04 g of citric acid, and 30 mL of ionized water. The content of phytochemical elements ranged from 0.11 ± 0.001 to 0.49 ± 0.08 mg/100 g. Cottage cheese served as a basis for another dairy product fortified with BAS obtained from Scutellaria galericulata. The formulation included 81 g of cottage cheese, 10 mL of cherry jam, 9 g of sugar, and 0.025 mL of scullcap concentrate. The content of biologically active substances in the finished product varied from 0.09 ± 0.02 for luteolin to 0.48 ± 0.11 for baicalin. The whey drink fortified with the BAS extracted from Rhodiola rosea and the cottage cheese product fortified with the BAS isolated from Scutellaria galericulata satisfied 40–45% and 55–60% of the reference daily intake for phenolic compounds, respectively. The obtained data made it possible to recommend the new functional foods for commercial production. Conclusion. A set of experiments was performed to isolate biologically active substances from Rhodiola rosea and Scutellaria galericulata. The research developed and tested formulations of two new functional products based on whey and cottage cheese.
One of the ways to eliminate population diseases and increase the body is resistance to adverse environmental factors is the systematic use of functional food products enriched with a complex of biologically active substances with a wide range of therapeutic effects. The creation of a new, unique functional dairy product was preceded by long-term comparative biochemical studies of Scutellaria baicalensis Georgi and Scutellaria galericulata L. In the grass and roots, biologically active substances of a phenolic nature, such as baicalin, vogonin, scutellarin, etc., were found useful for medicinal purposes. The use of extracts from the of Scutellaria galericulata L. in the development of a functional product based on sour-milk fractions made it possible to obtain curd mass enriched with the biologically active substance of this plant. The functional product meets the organoleptic, physico-chemical, tasting requirements for new functional products and is recommended for introduction into the diet of different population groups by age and functional activity.
Objective: obtaining an enriched curd product containing an extract of the common skullcap to expand the range of products that have a comprehensive therapeutic and preventive effect.
