Creation of new multifunctional materials based on renewable raw materials is a major direction in recent years. Large-tonnage waste of rice production (husk, straw, bran) of the Far East is a promising raw material base for obtaining such materials. Composition of rice bran includes inositol hexaphosphoric acid and its derivatives (phytin, phosphoinositol) which are capable of chelating polyvalent metal ions. Bismuth (III) is one of natural water pollutants that come from leaching of bismuth-containing minerals and activities of pharmaceutical and perfume industries. The goal of this work is to study removal conditions of bismuth (III) ions from aqueous solutions of a phytic acid derivative obtained from rice bran. It is shown in the work that with a sorbent: solution ratio of 1: 100, bismuth ions are removed from the solution by 89 %. It was found that removal of bismuth cations depends on the initial concentration (3.17–51.90 mg/l) and varies from 13 to 96 %. A comparative analysis also showed that chromium (III) ions are removed from aqueous solutions by a phosphorus-containing product better than bismuth (III) ions. These studies allow us to give recommendations on the choice of materials for treating solutions from heavy metal ions, expanding the range of currently used natural sorbents based on plant materials and solving at the same time an urgent environmental and economic problem - the disposal of rice production wastes.

Plant materials that are used for the production of extruded meat analogs are often nutritionally incomplete and also contain antinutrients, thus there is a need to explore alternative plant proteins and pre-treatments. This study demonstrates application of phytase and fermentation to a pea-oat protein blend with a good essential amino acid profile and subsequent texturization using extrusion cooking. Enzymatic treatment reduced the content of antinutrient phytic acid by 32%. Extrusion also degraded phytic acid by up to 18%, but the effect depended on the material. Differences in physicochemical, sensorial, and textural properties between untreated and phytase-treated extruded meat analogs were small. In contrast, fermented material was more difficult to texturize due to degradation of macromolecules; physicochemical and textural properties of extrudates were markedly different; sensory analysis showed enhancement of flavor, but also detected an increase in some unwanted taste attributes (bitterness, cereal and off-taste). Phytic acid was not degraded by fermentation. Analysis of volatile compounds showed extrusion eliminated volatiles from the raw material but introduced Maillard reaction products. Overall, phytase treatment and fermentation demonstrated the potential for application in extruded meat analogs but also highlighted the necessity of optimization of process conditions.

Recently, there has been an increasing interest in whey drinks. It is possible to expand the range of whey drinks and regulate their nutritional value due to the wide use of a variety of fillers. Non-traditional local plant materials can be used as fillers. The products of processing (powders, juices, syrups) of fruits and berries are more and more widely used. The value of wild fruits, along with a pleasant taste, is determined by the content of vitamins, minerals, antioxidants and other biologically active substances that play an important role in human nutrition, regulate metabolic processes, and affect the functions of individual organs. The aim of the research is to study the effect of fruit syrups on the nutritional value of whey drinks. The fruits of the following wild plants are consid- ered as the objects: common viburnum (Viburnum opulus), cinnamon rosehip (Rosa cinnamomeal), raspberry (Rubus idaeus L.). The choice of raspberries, rose hips and viburnum as raw materials for enriching drinks is due to the high content of biologically active substances, such as vitamins C, B, E, a fairly large raw material base, environmental friendliness, and availability. The article considers the results of the use of fruit syrups obtained from rose hips, viburnum and raspberries in the preparation of whey drinks. The influence of the dosage of fruit syrups (5 %, 10 % and 15 %) on the organoleptic and physicochemical indicators of the quality of whey drinks has been established. The optimal dosages of syrups from fruits of wild plants in the preparation of whey drinks have been determined. Rosehip, viburnum and raspberry syrups have a high nutritional value, which will enrich whey drinks and give them a functional focus.

Acid–base titrations in aqueous and non-aqueous solutions, titrations with metal ions, and analyses of various metal phytates support beyond question the 18-acid structure of phytic acid. Six of the hydrogens are too weakly acidic to be ordinarily titratable in water; in aqueous solution, two distinct breaks occur in the titration curve corresponding to the titration of 8 and 12 protons of phytic acid.

The article analyzes the state of the phosphate raw material base in Russia and its role in the economic development of the country and in domestic agriculture especially. The problems that prevent the creation of a modern powerful phosphate production capable of satisfying the existing demands of agriculture in phosphoric mineral fertilizers are highlighted. The possible directions of the development of the phosphorus industry in the regions for the near and distant prospects are analyzed. The aim of the article is to analyze the current state of the domestic mineral resource base to produce phosphorus fertilizers, the acute shortage of which hinders the development of the country's agriculture. Actual base for research was mainly processed materials from specialized scientific articles and publicly available publications. In addition, data collected by the authors during thirty years of studying phosphorite deposits in Russia and foreign countries were involved. The analysis of published materials of leading Russian producers of phosphorus products, mining companies, databases of specialized federal and regional geological companies. It is concluded that before the country's geological services, the most important task remains to identify deposits of high-quality phosphate ores, and especially in Siberia and the Russian Far East. Significant prospects for the development of these regions are opened by the Northern Sea Route. The planned pace of its development offers unique opportunities for the economic development of the Taimyr-Anabar region, where huge resources of apatite-bearing carbonatites of the Tomptor alkaline massif and Meimech-Kotuy province are concentrated.

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.

Abstract The European Union’s embargo on Indonesian crude palm oil (CPO) has resulted in excess of domestic palm oil reserves. The embargo has resulted in a build-up of domestic CPO due to the fact that the majority of Indonesia’s CPO production is exported overseas. The CPO price has dropped in recent months as a result of CPO overstock. On the other hand, as a by-product of rice production, Indonesia produces millions of tons of rice bran. The bran is treated more as waste than a resource for raw material to produce valuable products, such as bran oil. The need for lubricants in Indonesia is expected to rise as the number of cars and industries grows. As a result, some lubricant requirements must be met through importation because domestic manufacturing is insufficient. Palm oil and bran oil are both excellent candidates for conversion into biolubricants. This paper looks at the possibility of biolubricant production in Indonesia using alternate raw materials rather than petroleum-based sources. The paper begins by detailing the country’s lubricant demand, then moves on to the probable availability of biolubricant raw materials in Indonesia, and finally to the biolubricant process production method.
