The increase of functional food production makes the search for new non-traditional raw materials and the selection of methods for their processing relevant. Methods for obtaining biologically active substances of a lipid nature from valuable raw materials extracted from hunting animals (bear, badger, marmot and beaver) are of particular interest. The purpose of this review is to analyze the existing methods of obtaining rendered fat from raw fat and evaluate them. The objects of analysis were the data of scientific articles, patents and studies on the extraction of the lipid fraction from raw materials of animal origin from 2017 to 2021. In the work, various methods for extracting fats were considered. Their systematization, analyze, and description were carried out, indicating the advantages and disadvantages. The considered methods for extracting lipid components can be used in the process of rendering fat from non-traditional raw materials of animal origin. When using the dry rendering method, the heating of adipose tissue is carried out by the conductive method, which leads to oxidative processes and a decrease in the quality of the finished product. The wet rendering method is carried out by interacting raw fat with a heating agent – water or live steam, which, by varying the temperature and duration of exposure, allows to preserve the properties and quality of the product. Wet rendering methods are the most effective. These methods allow to obtain a high-quality finished product, as well as to produce the maximum yield of valuable lipid components of raw materials. To accelerate the technological process with the wet method of exposure, it is possible to use a biocatalytic method. The results of the research can be used in the development of schemes for obtaining biologically active substances of a lipid nature from valuable expensive raw materials extracted from hunting animals.
The problem of adaptation to difficult life situations is crucial for the current period of society development. The study of family coping as a support mechanism makes it possible to expand the understanding of adaptation mechanisms. The question of joint coping is connected with characteristics of social interaction, role behavior, degree of internality of the person, overcoming strategies. Cognition-based, emotion-based and behavior-based joint copings are distinguished. Family stress is the development of individual stress, with increased demands on the social and psychological resources of the family. The conducted research includes the analysis of personal features: self-relationships, coping strategies, psychological defenses, quality of life assessment, tendency to freeloading, degree of subjective control, and family features, which include factors of family environment and marital coping. The novelty of the research is associated with the definition of personal and interpersonal predictors of marital coping styles. The methods of mathematical statistics have been applied. The author concludes that the style of marital coping is associated with both the resources of the individual and the situation, and, directly, the ways of coping, which are characteristic of the individual. Resourcefulness has been studied both in terms of personal adaptation mechanisms and characteristics of family environment.
This paper presents the results of experimental studies on the intensifi cation of dehydration of mixed sediments of oil emulsion and acid-base wastewater. The study of determining the optimal doses of coagulants POLYPACS-30 LF, POLYPACS-F, POLYPACS-PFS was carried out. The properties of mixed sediments were found. The results are shown using X-ray phase and thermogravimetric analyzes on the D8ADVANCE devices of the fi rm Bruker (Germany) in Cu-K2-radiation and NETZSCHSTA 449 F1 by determining the composition of precipitation. The composition of the slag was determined using X-ray fl uorescence analysis - X-ray phase and X-ray X-ray spectral analyzes. The X-ray patt erns were taken on an automated X-ray diff ractometric equipment from ShimadzuXRD-7000S (CuKα radiation). XRF was carried out using an information retrieval system of X-ray phase identifi cation of materials (IPS FI), combining qualitative and semi-quantitative (by the method of “corundum numbers”) analysis. For semi-quantitative XRD, the method of fundamental parameters was used (wave X-ray fl uorescence spectrometer of the ShimadzuXRF-1800 company). Obtained data on the study of the properties and composition of mixed precipitation can be for the development of technology utilization.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
