The article describes an autoclave thermal processes model, which is used for the simulator of canned food sterilization process. The simulator is based on a simulation model that adequately describes the reaction of the autoclave to the actions of the control system and the operator of the sterilization unit. The model’s parameters were obtained by means of experimental data processing. The computer program ”autoclave Model” for simulating sterilization process in the steam and water environment is described. The examples of the canned food’s manual control sterilization modeling are shown. The results of numerical mathematical modeling of canned food sterilization processes in the autoclave showed a high degree of the implemented process models quality of approximation. The calculation schemes done as a result of the mathematical models creation were used to develop a hardwaresoftware complex of the sterilization process simulator. The increase of training level on carrying out process of canned goods sterilization will be provided as a result of designing the simulator of sterilization process in educational process. Consequently reducing defects in production and improving the quality of canned products are expected.

The article presents the overview of the main technological processes in fish structured products dehydration. The rational modes of the technological process of minced fish raw materials with various initial moisture and fat content heat treatment are determined. One of the main tasks of the fish processing industry development which allows increasing the profitability of products and their quality is improving technological processes. The scientifically substantiated choice of resource and energy-saving modes of processing food materials is highly important in this case. It will reduce not only production costs but also emissions of harmful substances into the environment and increase the efficiency of using equipment. It must be taken into consideration that the optimization of dehydration technological processes without identifying their patterns is extremely difficult. Increasing efficiency and controlling technological processes makes sense only on the basis of patterns. The effectiveness of the hydrobionts processing determines the quality and cost of finished products manufacturing while fish processing enterprises working. The development and implementation of highly efficient technologies with the use of resource-saving technical systems, for example, using heat pumps, makes it possible to produce cost-effective high-quality products.

The article presented the overview of the main seasonal dynamics of photosynthetic pigments (chlorophyll a, carotenoids and phycobiliproteins) as well as their ratios for the mass species of the Murmansk coast of the Barents Sea red algae Palmaria palmata. The concentration of pigments depends on the level of illumination and temperature which is statistically confirmed. The results of the research showed that the chlorophyll content of Palmaria palmata is characterized by a significant decrease in summer and an increase in winter which is in contrast to the change in the level of illumination. It was proved that in winter with a decrease in light, the efficiency of photosynthesis is provided by the accumulation of pigments including phycobilins. It is suggested that the relationship of reproduction, namely the release of tetraspores with the reduction of phycobiliproteins, since the presented process requires significant energy costs. It is shown that the concentration of phycobilins decreases with increasing light intensity. Prolonged presence of algae under high light intensities reduces the amount of photosynthetic pigments. The results of the research showed that the number of pigments decreases with low temperatures and vice versa their number increases with increasing temperature. A significant negative correlation between the water temperature and the main pigments of the photosynthetic apparatus – chlorophyll a and carotenoids was revealed. The concentration of carotenoids and phycobilins depends on the function they perform: in summer - photoprotectors, in winter-additional light collectors. Palmaria has a maximum content during the polar night. Significant changes in the ratios of Car/Chl a, PhE/ Chl a, PhE / PhE depending on environmental factors are shown.

The article deals with the relevance of the spring waters study and presents the results of the springs’ classification in Murmansk and outskirts of the town on geological and ecological characteristics. Spring Water is the main source of water for drinking, agricultural and industrial needs. The availability of water determines the location and activities of people in the area. Our growing population experiences great demands on natural freshwater resources. However they are under various forms of pollution such as agricultural, industrial and domestic. In this research spring water samples were taken from the springs of Murmansk and outskirts of the town. Physical and chemical parameters were analyzed. The characteristics of each parameter were compared with the standard data established in the Russian Federation for this indicator. The characteristics of each parameter were within safe limits.

The economy of the Limansky district is based on the use of natural capital, and its preservation is of paramount importance for the region. Ecological-genetic-economic studies demonstrate the need for adequate economic accounting of natural capital and the environmental factor in economic decisions related to the development of the territory and transport infrastructure of the region.
