In recent years, there has been an increasing interest in medicines produced on the basis of medicinal plant raw materials. Information about the concentration of elements by medicinal plants and substances allows us to see a new aspect of their practical application, to identify new medicinal properties. In this regard, the comparative study of the elemental composition of strawberry leaves and dry strawberry leaf extract is of practical interest for the further development of dosage forms and the formation of scientific justification for their use in medical practice.

A large number of biologically active substances, organic acids, tannins, and pectin substances were detected during the study of fruits, leaves, and pulp of the fruits of mountain Ash. The content of these substances in leaves and pulp will significantly expand the arsenal of medicinal plant raw materials used. Given the wide distribution of mountain Ash in the territory of the Russian Federation, harvesting leaves from the same plants after harvesting the fruit and using pulp will make it possible to obtain new phytopreparations.

  The article is devoted to the study of the chemical composition, physical and thermal-pfysical characteristics of damp apple pomaces and the identifying patterns of influence of drying temperature the functional composition and gel-forming ability of pectin. The research is aimed at obtaining initial data for the subsequent calculation of the main technological, hydro-mechanical, thermal, structural and economic characteristics of devices for drying the plant raw materials, ensuring the environmental safety and high quality of pectin-containing raw materials, the reducing heat and energy costs. As a result of the study of the thermal characteristics of apple pomaces, the critical points (temperature conductivity – 16.5 x 10-8 m2/s, thermal conductivity – 0.28 W/m K, heat capacity – 1627 j/(kg K)) at a humidity of 56 % are determined, which characterizing the transition from the extraction of weakly bound moisture to the extraction of moisture with strong bonds (colloidal, adsorption). It was found that the pomaces obtained from apples of late ripening have a higher content of solids (21-23 %), soluble pectin and protopectin (2.5-4.5 %). Dried pomaces obtained from apple varieties of late ripening contain up to 25 % pectin, which allow us to recommend them as a source of raw materials for the production of pectin. The optimum modes of preliminary washing of raw materials are offered, allowing to the remove the ballast substances as much as possible. It is established that when the drying temperature increases, the destructive processes are catalyzed: the strength of the pectin jelly and the uronide component and the degree of pectin esterification are reduced. The optimum drying temperature of damp apple pomaces is 80 0C, at which the quality of pectin extracted from the dried raw materials is maintained as much as possible. It is shown that the most effective for the pectin production is a fraction with a particle size of 3-5 mm, which allow us to extract up to 71 % of pectin from raw materials.

The article provides brief information about cardiotonic, sedative, cytostatic, diuretic, and antibacterial effects of biologically active compounds of Adonis L. (Ranunculaceae) species. Chemical studies allowed to identify the cardiac glycosides, or cardenolides: or cardenolides: adontoxin, adonitol, adonitoxigenin, acetyldigitoxin and others. In scientific medicine, it is currently allowed to use Adonis vernalis L. Other types of Adonis have a similar chemical composition and are offered as substitutes for this official species, for example, Adonis apennina L. Many Adonis species have limited natural resources, and in some regions are rare, requiring conservation of their natural populations. The search for alternative sources of medicinal plant raw materials, based on this, is relevant. The experimental part of our research was carried out using the morphological and geographical method with the involvement of information on ecology and phenology. For the first time summarizes the diagnostic features of Adonis flora of Russian flora. Previously unknown structural features (shape and size of anthers) were identified that characterize the subgenera Adonanthe and Adonis. Taxonomic study of the genus Adonis of the Russian flora allowed us to determine its species composition, clarify its systematic affiliation, and nomenclature synonyms. 9 species were identified. Of these, 6 are perennials belonging to the subgenus Adonanthe, section Consiligo, which includes 2 subsections: Amurenses (2 species) and Vernales, which is differentiated into 2 rows: Apenninae (2 species) and Vernales (2 species). Subgenus Adonis is represented by 2 sections: Adonis (1 species) and Lophocarpa with sections Aestivales (1 species) and Dentatae (1 species). For all the considered species and varieties, the main distribution areas are given. A key has been compiled to determine the wild Adonis species distributed in Russia.

Consumer demand for both plant products and meat products enriched with plant raw materials is constantly increasing. Therefore, new versatile and reliable methods are needed to find and combat fraudulent practices in processed foods. The objective of this study was to identify oilseed species-specific peptide markers and meat-specific markers that were resistant to processing, for multispecies authentication of different meat and vegan food products using the proteomic LC-MS/MS method. To assess the limit of detection (LOD) for hemp proteins, cooked meatballs consisting of three meat species and hemp cake at a final concentration of up to 7.4% were examined. Hemp addition at a low concentration of below 1% was detected. The LOD for edestin subunits and albumin was 0.9% (w/w), whereas for 7S vicilin-like protein it was 4.2% (w/w). Specific heat-stable peptides unique to hemp seeds, flaxseed, nigella, pumpkin, sesame, and sunflower seeds, as well as guinea fowl, rabbit, pork, and chicken meat, were detected in different meat and vegan foods. Most of the oilseed-specific peptides were identified as processing-resistant markers belonging to 11S globulin subunits, namely conlinin, edestin, helianthinin, pumpkin vicilin-like or late embryogenesis proteins, and sesame legumin-like as well as 2S albumins and oleosin isoforms or selected enzymic proteins.

Limitations of plant-based dairy alternatives as sustainable foods are their relatively low protein content and low sensory appeal. In this study, we used a consumer-led product development approach to improve the sensory appeal of existing prototypes of 3-blend dairy alternatives produced from melon seeds, peanuts and coconut. We used Relative Preference Mapping (RPM) and consumer acceptance testing using the 9-point hedonic scale to respectively identify innovative flavours and deduce the effect of ingredient components on consumer sensory appeal. Mixture design was used as the formulation tool to obtain optimized prototypes of the 3-blend dairy alternatives. Proximate analysis of the new prototypes, instrumental color assessment and consumer testing provided a basis to select a sustainable 3-blend dairy alternative. This prototype had a relatively high protein content (2.16%), was considered innovative by target consumers and also had a moderate liking score (6.55 ± 1.88) on the 9-point hedonic scale. Prototypes with higher protein content had low sensory appeal and were not considered innovative. Other prototypes with innovative sensory appeal had low protein content. By combining different plant raw materials and utilizing different sensory testing methods, we were able to design sustainable plant-based dairy alternatives which can be further optimized.
