Perishable food is food which shelf life’s duration is not more than 5 days. Therefore, extending the shelf life of perishable products is necessary. This action is needed, for example, for the transportation of products over long distances and their further sale. Food spoilage can be caused by microorganisms, enzymes or improper storage. Lower temperatures and preservatives are often used to increase the shelf life, and the preservatives can be chemically synthesized or natural. The aim of the article is to find ways to extend the shelf life of semi-finished potatoes using natural preservatives. Moreover, it is aimed at finding ways using natural preservatives. The research is carried out on the potato salad example. The graphs and tables show the results of the experiments. The results showed that 6% vinegar is the most suitable for extending the shelf life of semi-finished potatoes.

Methods of geometric morphometrics were used to analyze differentiation of three larch species – Larix gmelinii, L. cajanderi, and L. sibirica, which are the most common larch species in North Asia, by the shape of the cone scales. The samples of seed-bearing scales of mature cones were collected from 185 trees in 8 populations, which represented the different regions of the Larix species areas. Ten outline points on one side of the cone scales were chosen to characterize their shape. Patterns of shape variation were depicted using Generalized Procrustes Analysis (GPA). PCA results of partial warps (PW) revealed the shape differences of cone scales among the three species of Larix. The CVA of relative warps (PCA scores) showed that the Larix species were all successfully discriminated, and populations within the species were considerably differentiated. Geometric morphometrics can be used as an effective tool to analyze inter- and intra-specific differentiation of Larix species based on the shape of cone scales.

The paper describes a new technique for processing experimental data on sorption capacity (E) of variously composed natural soils in relation to heavy metals in aqueous solutions. The calculation scheme is based on an inhomogeneous system of equations, compiled from the data on mineral composition of soils and the E values. Such a system of equations was compiled for the experimental data on the sorption characteristics of natural soils (as suspensions) with respect to Cu2+ ions (of up to 1000 mg/l) from CuSO4·5H2O solutions. The highest sorption characteristics with respect to Cu2+ ions from solutions of CuSO4·5H2O were associated with uneven-grained aggregates of calcite and chlorite followed by quartz and montmorillonite; dolomite and hydromica had the lowest sorption characteristics.

In the context of increasing anthropogenic impact on the environment, the study of the mechanisms of plant adaptation is an actual problem. To diagnose ecological troubles, it is advisable to study the indicators characterizing metabolic processes in autotrophic plants. The change in the parameters of the photosynthetic apparatus and antioxidant system in silver birch (Betula pendula), European spruce (Picea abies) and dandelion (Taraxacum officinale L.), depending on the intensity of anthropogenic load, was studied. The pigment composition of plants and the activity of antioxidant enzymes can be used as markers of the anthropogenic pollution level of a territory.

Creation of high quality diesel fuels for internal combustion engines that meet stringent operational and environmental requirements is currently an urgent task. The most rational way to improve the performance characteristics of diesel fuel, its environmental properties, as well as to reduce losses during its storage, is to use polyfunctional additives. Requirements for the structure of polyfunctional additives are formulated. It is shown that their stabilizing and protective effects are the higher, the greater the value of the dipole moment and total electron density on heteroatoms. Amides and esters of higher aliphatic acids, synthesized from renewable diesel raw materials, as well as molecules of azo compounds including aromatic fragments and electron-donating functional groups, are promising multifunctional additives to diesel fuel.

The article presents the results of modeling the process of dust deposition and determining the most efficient parameters of electric precipitators for air purification of the workplaces of operators of technological lines of flour mills and grain processing enterprises. It also provides a mechanism for dust coagulation during the operation of electrostatic precipitators. The study is relevant because the air working zone and the air of milling and grain processing enterprises, in particular, contains suspended aerosol with volatile fractions of organic substances. It has a negative effect on both the health of workers and the efficiency of production equipment. The efficiency of the proposed model of dust deposition from the air of the working zone is based on the use of electric charges on dispersed particles, which in turn makes the aerosol sensitive to the external electric fields.

The research was conducted in the conditions of the South-East of the of the Central-Chernozem zone (Kamennaya Steppe) in 2018-2020 biennium. Features of formation of reserves of productive moisture in agroforestry complex are shown. Data for studying changes in soil moisture profile are presented. The first decade of the current century was characterized by a widespread rise in the ground water level (GWL) to 1.2-2 m and the formation of seasonally waterlogged soils. In the dry conditions of 2010, the most critical conditions developed. The entire 200-cm layer of soil in the summer was characterized by a complete lack of available moisture. In the following years, up to 2020, at all research sites, the GWL fluctuates in the range of 3-4 m.

The article analyzes the raw materials of the terrestrial part of a perennial spicy-aromatic plant of the family (Lamiaceae Lindl.) Mentha piperita L., introduced into the forest-steppe zone of the South Urals, for the content of 37 chemical elements. The studied species proved to be a concentrator of chemical elements. Mentha piperita L., is an accumulator: in the terrestrial part of this plant, the concentration of three elements (zinc, molybdenum, silver) was higher than in the soil. The content of most of the studied elements in the terrestrial part of the plant does not go beyond the limits of fluctuations of chemical elements in plants growing in the Republic of Bashkortostan. Our data on the content of chemical elements in the object of study allow us to offer peppermint to reduce or eliminate the imbalance of zinc and molybdenum elements in the body.
