The development of new plant growth regulators based on products of chemical processing of plant raw materials is currently an urgent task for increasing yields in agricultural production. On the basis of carboxymethylated plant materials, "Eco-Stim" plant growth regulator has been developed. The purpose of this work is to study the effect of the storage conditions of solutions of carboxymethylated plant materials in "Eco-Stim" as part of the preparation on their rheological and growth-regulating properties. The rheological properties of the aqueous systems of carboxymethylated pine, sunflower, and oat chaff have been studied at concentrations of 0.2–15%. It is established that the change in viscosity as a result of the shear rate of the systems studied is more complex in comparison with aqueous solutions of Na-CMC. Storage of solutions of carboxymethylated vegetable raw materials for 20 months, as well as the processes of freezing and thawing for 6–9 weeks have practically no effect on the viscosity and growth regulating properties of carboxymethylated vegetable raw materials. The studied systems make it possible to increase the germination of wheat seeds Omskaya-36 to 80–87% and to increase the length of the root by 4–10 times and the stem by 1.5–2 times compared to the control.

The results of studies on the effect of negative temperatures (the process of freezing - defrosting) on aqueous solutions of preparations obtained by carboxymethylation of waste products from the processing of plant materials (oat flower films, buckwheat husks, poplar leaf litter) are presented. The purpose of this paper is to study the effect of storage conditions of solutions of carboxymethylated plant materials at low temperatures on their growth-regulating properties. The properties of aqueous solutions of carboxymethylated sunflower husks, oat flowering films, poplar leaf litter with a two-fold freeze-thawing cycle for defining growth-regulating ability were studied. It was established that all the studied samples retain their growth-regulating ability with respect to Ivory oats and Omskaya 36 wheat. Freezing and thawing processes enhance their growth-regulating effect. The studied biological products can increase seed germination and enhance the growth processes of the studied crops. For oats, the germination rate increased by 5–10%, the length of the root increased by 1.6–3.2 times, and the stem by 2.5–4.8 times as compared with the control. For wheat, the germination rate increased by 10–18%, the root length increased by 1.5–2.9 times, and the stem by 2.0–4.8 times as compared with the control.

The article considers the possibility of expanding the range of fermented milk products enriched with natural sources of biologically active substances, which is an urgent task today, as it corresponds to the concept of state policy of the Russian Federation in the field of healthy nutrition. As a solution to this problem, it has proposed to enrich the curd mass as part of the daily diet. Promising plant raw materials of the Far Eastern region, such as Ahnfeltia tobuchinensis, a representative of the genus of red algae growing in the Far Eastern Seas, are used as functional and enriching ingredients; Dahurian larch wood extract – arabinogalactan (Lavitol-arabinogalactan) and peppermint (Méntha piperíta). Grounded ahnfeltia was used in the size of not more than 0,5 mm. On the basis of the analysis of the composition and properties of the applied non-traditional additives, the possibility of enrichment of curd products with dietary fiber and organic iodine from plant components has been substantiated. Optimal ratios of enriching prescription components to the weight of cottage cheese in a finished product are the following: ahnfeltia powder – 1,5%, arabinogalactan – 2,5%, peppermint – 1%. Also, when determining the optimal dosages of the introduced components, it is proposed to replace the prescription amount of sugar with flower honey, which is a natural sweetener and a powerful antioxidant. Organoleptic and physicochemical parameters of the finished samples have been analyzed. As a result of the research the functional curd product one portion (100 g) of which is capable to satisfy daily physiological need of an organism for iodine for 29,32%, in dietary fibers for 12,38% has been developed.

Common characteristic of salad products is presence of cut raw vegetables in its composition. Cold cutting helps surface microorganisms penetrate into deep layers of the product. Hygienic cleanliness of raw ingredients is the major factor which contributes to storage stability of salad products. One of the most effective methods that helps enhance salad storage stability is initial treatment of vegetable raw materials with antimicrobial solutions. The author presents information on using solutions of hydrogen peroxide and peroxyacetic acid, sodium hypochlorite and compositions containing peroxide compounds and acetic, benzoic, sorbic, ascorbic, citric, lactic and other acids as well as their salts and containing guanidylic compounds. The article reveals that antimicrobial action of lactate-containing processing aids improves sufficiently if polymer cation-active compounds are introduced into their composition. The goal of the research is to study application effectiveness of new processing aids for treatment of raw peeled cut vegetables to reduce bacterial content and enhance storage stability before thermal treatment (boiling). The author tested the aids based on lactate-containing components. Physicochemical and physical parameters of the aids and their aqueous solutions are the following: active acidity (pH), titratab6le acidity, water and volatiles mass fraction, dynamic viscosity, surface tension. The article presents the data which characterize change in surface tension of aqueous solutions of the aids at the water-air interface depending on their concentration. It also gives quality indicators and microbial parameters of raw peeled cut vegetables after their processing with solutions of the aids. It was found out that treatment of raw peeled cut vegetables with processing aids based on lactate containing components prolongs their shelf life from 3 hours according to the applicable technology up to 48 hours.

The aim of this work is to review and analyze the data published in the modern scientific literature obtained in pharmacological, pharmacognostic and pharmacotechnological studies of various types of raw materials obtained from members of the family Lamiaceae L., which were sources of biologically active substances, pharmaceutical substances, total extracts and the drugs – with a neurotropic activity.Materials and methods. For the review, we used the information of scientific literature from open and accessible sources of the last twenty years, located in the scientific and technical libraries of institutions, as well as in electronic databases: Elibrary, PubMed, Scopus, Cyberleninka, GoogleAcademy, J-Stage. The search inquiries were: the species of the family Lamiaceae (Russian and Latin), the samples of medicinal plant materials based on them as well as the names of the drugs and biologically active substances obtained from these raw materials.Results. When working with the sources of scientific information, the main attention was paid to pharmacologic tests performed during the studies on laboratory animals and proving the presence of neurotropic activity in the studied objects – essential oils and extracts from plant raw materials: aqueous, aqueous alcoholic, and methanol ones. It has been established that the potential of the therapeutic and preventive application of pharmaceutical substances and drugs based on the medicinal plant materials obtained from 30 genera members of the Lamiaceae family, remains unrealized despite the close attention of various researchers.Conclusion. This review comprised 71 species from 30 genera. Despite the significant level of the previous study presented in the analysis of this publication, an enormous potential of this family’s species remains unexplored. In the future, they can be of both – pharmacognostic and practical interest, in particular, in creation of new medicinal preparations of the neurotropic action based on them.

Introduction. Semi-finished choux dough has neither vitamins nor minerals. However, its nutritional value can be increased by adding vegetable raw materials. The research objective was to evaluate the possibilities of using spicy vegetable raw materials in the formulation of semi-finished choux dough. Study objects and methods. The study featured fresh parsley (Petroselinum crispum), basil (Ocimum), celery (Apium) leaves and stems, and IR-dried powder of celery stalks. Standard research methods were used to determine the sensory, physico-chemical, and nutritional properties of the resulting choux samples. Results and discussion. Classical semi-finished choux dough with craquelin served as control sample. Fresh spicy vegetable raw materials degraded the sensory characteristics of the product. However, powdered celery stalks did not interfere with the taste of the choux dough. They were added in the amount of 2.5, 5.0, and 7.5% by weight of wheat flour. The celery powder gave the dough a sour-spicy flavor, as well as increased the content of vitamins B (up to 10%) and beta-carotene (up to 70%) in the finished product. Conclusion. The sample with 5% of IR-dried celery powder proved optimal for choux dough. It increased the content of vitamin B2 and beta-carotene, thus improving the nutritional value of the semi-finished product. In future, the powder can be tested as part of bakery filling in combination with ingredients that mask the typical celery taste.

The possibility of recovering the spent cooking solution with the replacement of the missing amount of lignifying reagents in the oxidative-organic solvent cooking of non-woody plant raw materials (rice husk) with preliminary alkaline treatment and the production of technical pulp with desired properties is shown. Analysis of scientific and patent information revealed that two methods of regeneration are used for regeneration of spent cooking solutions during oxidation-organosolve cooking: azeotropic distillation and return of part of the spent cooking solution for re-cooking with the completion of the missing amount of reagents. For the oxidation-organosolvent cooking non-wood plant materials the most promising is the second option. To avoid the preservation of mineral components in industrial pulp, non-wood plant materials are subjected to alkaline treatment. It has been established that to obtain technical pulp with recovery of the spent cooking solution, it is required two times less acetic acid and 1.7 times fresh water as compared to oxidation-organic solvent cooking under standard conditions with a constant amount of caustic soda.
