The emulsifying ability of pumpkin seed flour determines the range of its application in food technology. Identification of varietal characteristics of pumpkin seed flour proteins raises the efficiency of its use. The pumpkin seed flour of the four most common and different in ripening period kinds was selected for study, such as Kroshka, Vitaminnaya, Mozoleevskaya and Golosemennaya. The protein composition of the seed flour of the selected pumpkin varieties was evaluated by such indicators as the mass fraction of pro-teins, the distribution of proteins into individual fractions and their polypeptide composition. Pumpkin seed flour Golosemennaya contains albumins and globulins most of all, it has the most active low- and high-molecular polypeptides and the best ability to form emulsions.

The problem of adaptation of the Steller's northern sea lion (Eumetopias jubatus, Schreber, 1776) to the coastal water area adjacent to the town of Petropavlovsk-Kamchatsky is presented in the article. There are two stages in the sea lion synanthropization. The first stage is associated with rookeries formation, foraging near vessels and in the bay in area, in the usual habitat of these animals, in seawater. The second stage is connected with pioneering a new habitat and feeding on land. During sea lion adaptation to new conditions over a 20-year peri-od, the fear of humans noticeably decreased in animals, new behavioural traits such as cadging appeared. The group of sea lions wintering in Petropavlovsk-Kamchatsky during the 20-year period was characterized by sta-tistically significant fluctuations in numbers by year and season. The further coexistence of wintering animals depends on the dynamics of the influence of both natural and anthropogenic factors.

The method for calculating the strength characteristics of a polyethylene cord taking into account the design and based on the study of its destruction processes was described. The calculation method includes determin-ing the actual inner diameter of the braid, which allows identifying the effective layout of the cord braid and to determine the possibility of core and cord joint work, which ensures maximum breaking load of polyeth-ylene cords. To determine the diameter of the core formed by the threads the optimal ratios were used. The formulas for determining the ratio of the braid and core threads length were obtained, which allow to determine the utilization coefficient of braid threads included in the fracture process. The deviation of the results of calculated values due to the proposed method and experimental data do not exceed 3–5%. The proposed method can be used to calculate the strength characteristics of polyethylene cords, in which the joint work of the core and braid threads is structurally possible at break.

The role of natural self-purification processes aimed at restoring water original properties and composition increases in conditions of high anthropogenic pressure on freshwater ecosystems. A significant contribution to these processes is made by filter-feeding hydrobionts, which can deposit suspended particles from water column. A main part of the research in this area is devoted to filter-feeding mollusks – bivalves and gastropods, but gastropods are less studied. The data obtained during the experimental study of the filtration activity effect of the river Viviparus viviparus (L.) on the change in the optical density of the suspension of the unicellular algae Chlorella sp. are presented in this pa-per. The results showed that the average value of optical density of Сhlorella suspension in the presence of the mol-lusk decreased by 2 times, from (0.151 ± 0.0090) to (0.068 ± 0.0400) B. Various changes in optical density in each of the experimental glasses are associated primarily with the unequal physiological state of the mollusks. It was sug-gested that numerous populations formed as a result of V. viviparus invasion into the Novosibirsk Reservoir are able to change water quality, potentially affecting the functioning of the reservoir ecosystem.

The nutritional value of its individual organs and tissues was shown. The coefficient of nutritional significance of lipids was calculated. The requirements of regulatory documents to the quality of pollock and its safety according to parasitological indicators were analyzed. The existing and promising directions of using Pacific pollock as a raw material object for fishery industry were enumerated. The distribution schemes of products manufactured by different countries were developed. An overview of the ways of pollock processing into food products was made. The results of pollock production technologies that have been developed for several years and are currently being developed by the Food Production Technologies Chair of Kamchatka State Technical University were briefly presented. The conclusion about the high technological potential of Pacific pollock was made.
