Currently, the world practice of the food technology uses an integrated approach of the deep vegetable raw processing, including the secondary resources in order to reduce the direct costs and production costs. In this research, the quantitative and qualitative composition of the marcs obtained while producing the “Vigrass” juice from the wheat germ of 10–12 cm long is investigated. It is revealed that the volume of the obtained marcs is up to 35%, their humidity of 70–74% in the conditions of the “Prorostki” Ltd company production is determined. It has been studied that 100 g of marc contains: protein – 5.56 g, lipids – 3.96 g, organic acids – 0.93 g. It is established that the wheat sprouts marcs include the amount of P – active substances 110 mg/100 g, flavonoids 200 mg/100 g, chlorophyll 12 mg/100 g, tannin 370 mg/100 g, vitamin C 129 mg/100 g. It is identified that 12.83% of dietary fibers marcs include 6.81% of lignin, 1.50% of cellulose, 4.23% of hemicellulose and 0.29% of pectin substances. The dynamics of the vitamin C and chlorophyll content in the wheat sprouts marcs depending on the drying temperature is educed. It has been established that during the marc drying at high temperatures, the amount of vitamin C and chlorophyll decreases by more than 60% of the total content, which is consistent with the data of other authors. The technological parameters of the marc drying for the production conditions have been determined. They make possible to preserve the biologically active substances almost fully: temperature 40 °С, time 8 hours. A complex technology has been developed to process wheat sprouts to produce the “Vitgrass” juice and powder from marc.

Hedysarum neglectum is a forage plant. Xanthone glycoside - mangiferin is extracted from this plant and used for medicine "Alpizarin". In addition to substances of xanthone nature (mangiferin and isomangiferin) Hedysarum neglectum contains sugars, vitamins and provitamins, tannins; in the underground part it contains oligomeric catechins, isoflavonoids, butylphenols, alkaloids, tannins, flavonoids, saponins, coumarins, carbohydrates, vitamin C. For selecting optimal schemes of fractionization of substances, it is necessary to resort to multi-stage schemes of group-wide (preliminary) isolation and preparative accumulation. In particular cases, it is necessary to take into account the presence of concomitant substances, as well as the effectiveness and selectivity of the sorption-chromatographic technologies used. According to the results of the studies, the use of silica gel and sefadex LH-20 for the isolation of a complex of flavonoids and gallic acid is the most effective method for the selection of the optimal variant of the preparative isolation of the total amount of BAS in mcg/ml. The results of the research allowed us to identify the target biologically active substances with a degree of extraction of at least 80%: - fractions of xanthones, flavonoids, gallic acid.

Sufficient consumption of natural biologically active substances (BAS) – vitamins, dietary fiber, mineral compounds – reduces the risk of developing diseases associated with negative external factors. A large number of BAS are contained in the cherry plum fruits. Cherry plum is characterized by storage short term, during which quality changes are possible. Studies have been conducted on the low temperatures effect the change of BAS in cherry plum fruits. Studied objects were five cherry plum varieties grown in the Russian southern regions – Dinnaya, Zhemchuzhina, Obilnaya, Puteshestvennitsa, Neberdzhayskaya ranyaya. It was found that during storage, the physical and chemical parameters change slightly, the dry substances content decreases (within 1.3-3.2 %), sugars (5.5-7.0 %), the total acids content increases (2.8 3.3 %). The BAS content slight decrease during storage does not significantly affect the nutritional value of cherry plum fruits. The ascorbic acid reduction is 9.8-17.3 %, the anthocyanins content decreases on average from 16.9 to 19.7 %, the beta-carotene content decreases by 8.7-14.8 %, the reduction level of pectin substances is 15.75-22.2 %. Thus, the freezing method application allows to preserve valuable BAS in cherry plum fruits and use them in the future as a basis for the production of functional food products.

The aim of this work was to investigate and compare the amounts of biologically active compounds, dry matter and soluble solids in pulp and peels of four pear cultivars (‘Ksena’, ‘Beloruskaja pozdniaja’, ‘Alna’ and ‘Aleksandr Lucas’). The research was carried out at Vytautas Magnus University Agriculture Academy (Lithuania) in 2020. Four pear cultivars (‘Ksena’, ‘Beloruskaja pozdniaja’, ‘Alna’ and ‘Aleksandr Lucas’) were cultivated at a farm in the Joniškis District of Lithuania. Pears were grown following traditional pear production technology. The amounts of dry matter, soluble solids, vitamin C and fiber were determined using the standard method. The total content of phenolic compounds was determined using a Folin-Ciocalteu reagent with a UV/VIS spectrophotometer. The research results showed that significantly the highest amounts of soluble solids were found in the ‘Alna’ pear fruit pulp (14.25% f. w.). The ‘Alna’ peel sample had significantly the highest amount of total phenolic compounds (1290.99 mg 100 g–1 d. w.). The highest content of dry matter was found in the ‘Aleksandr Lucas’ pear fruit peel (24.67%). The ‘Aleksandr Lucas’ and ‘Beloruskaja pozdniaja’ pear fruit peel contained significantly the highest amounts of vitamin C (2.70 and 2.63 mg 100 g–1 f. w., respectively). The highest content of fiber was found in the ‘Ksena’ fruit peel (36.12% d. w.). The investigated pear peel sample had significantly higher amounts of dry matter, vitamin C, total phenolic compounds and fiber than the pulp. However, the pulp contains the highest contents of soluble solids.

Lithospermum erythrorhizon is a promising plant, its roots synthesize biologically active substances (BAS): naphthoquinone shikonin and its esters, which have antimicrobial, wound healing, anti-inflammatory, antioxidant, antineoplastic and other types of pharmacological action. The industrial harvesting of Lithospermum erythrorhizon is difficult due to its limited area, but there is a possibility to grow its cell culture using the biotechnological method, which opens up great prospects for the further isolation of these BAS. Previously, we proposed a composition and a technological scheme for the manufacture of polymeric films containing shikonin and its esters, isolated from a culture of Lithospermum erythrorhizon cells. This study is devoted to the development of approaches to the qualitative analysis of polymeric films. Three directions of qualitative analysis are considered: evaluation of external signs, determination of technological parameters of films, confirmation of the presence of naphthoquinones. The criteria of quality and methods of analysis in each direction have been determined. The presence of shikonin and its derivatives in the polymeric films was confirmed by color reactions, thin layer chromatography and spectrophotometry.
