In this study, using the HPLC method, 17 samples of nuts imported from Uzbekistan, Iran, China have been analyzed. The experimental part was carried out in an accredited testing laboratory of Nutritest LLP, Almaty. As a result of the research, nut samples taken from the Shapagat, Alem, Sharyn, Astanalyk Bazaar, Eurasia-1 markets exceeded the norms of fatty acid composition from 1 to 20% in all samples. In addition, differences were found in the fatty acid profile of nuts of different types and origin. Peanuts from China, for example, have the highest quantities of palmitic acid, whereas cashews from Iran have the highest levels of stearic acid. Almonds also have the highest oleic acid values, while walnuts have the highest linoleic acid levels. These results may be useful in understanding the differences between nuts and choosing the most appropriate options for consumption based on individual needs and nutritional recommendations","PeriodicalId":476095,"journal":{"name":"HERALD OF SCIENCE OF S SEIFULLIN KAZAKH AGRO TECHNICAL RESEARCH UNIVERSITY Veterinary sciences","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135428426","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, long-term storage of these strains often leads to diminished viability and biological activity. Thus, it is crucial to investigate the properties of cryopreserved strains stored at -80°C in a 10% glycerol solution within low-temperature refrigerators. This study aimed to comparatively analyze the viability of 129 lactic acid bacteria strains, including Lactobacillus sp., Lactococcus sp., and Pediococcus sp., cryopreserved from 2006 to 2020. Among them, 93 Lactobacillus sp. strains were categorized into three groups based on storage dates (2006-2007, 2013-2014, and 2017-2020). Viability titers were determined using the standard serial dilution method, counting microorganisms in CFU/ml. Regardless of the storage duration or species affiliation, the study identified lactic acid bacteria strains exhibiting both high (107 - 109 CFU/ml) and low (104-106 CFU/ml) viability titers. Additionally, the antagonistic activity of 33 Lactobacillus sp. strains was investigated using the delayed antagonism method, subdividing them into 17 strains with sufficiently high viability titers and 16 strains with low viability titers. The results revealed that 20% of strains with high viability titers and 27% with low viability titers exhibited relatively high antagonistic activity (with a zone of inhibition ranging from 10 to 18 mm). In both groups, strains with low antagonistic activity (with a zone of inhibition measuring 5-9 mm), particularly against Gram-positive and Gram-negative bacterial test-cultures, predominated. Significantly, 51% of lactobacilli strains demonstrated pronounced antagonism against Candida albicans ATCC- 885-653 test-culture. These findings underscore the practical importance of the study, emphasizing the necessity to analyze and select optimal concentrations of intracellular or extracellular cryopreservatives and to determine the initial viabilitytiter when storing strains for cryopreservation. Tailoring cryopreservation solutions to each strain can enhance the preservation of their original properties, ultimately improving overall preservation quality.","PeriodicalId":476095,"journal":{"name":"HERALD OF SCIENCE OF S SEIFULLIN KAZAKH AGRO TECHNICAL RESEARCH UNIVERSITY Veterinary sciences","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135428031","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Reducing food waste and transforming it into food and feed is a step toward the achievement of economic development while reducing adverse effects on the environment. Meat production and consumption have increased in recent years. Above 20% of meat is wasted in Europe throughout the different steps in the production chain. Meat waste and by-products are rich sources of proteins, bioactive compounds, essential amino acids, vitamins and minerals, and have a potential to be further used for dietary and non-dietary purposes. Bioactive peptides often have health-promoting effects such as antioxidant, anti-hypertensive, anti-inflammatory, antimicrobial and antitumor activities when ingested and absorbed by human beings. Some bioactive peptides were shown to reduce the risk of development of cancer, diabetes and cardiovascular disease, which are among the most common diseases currently. Several methods to isolate bioactive peptides from meat waste and by-products were developed. Enzymatic hydrolysis can generate hydrolyzates and certain bioactive peptides from larger proteins, and the hydrolyzates can be used as dietary supplements or as an additive to increase the protein content of food. Bioactive peptides can be isolated from the hydrolyzates and used as functional food components, dietary supplements or medicines. We concluded that wastes and by-products from the meat industry present an opportunity for the generation of health-promoting bioactive compounds which can be successfully used in food and other relevant industries. However, existing research mainly is mainly focused on theinfluence of individual bioactive peptides on certain health parameters and is mainly performed using in vitro methods. Thus, future research should be directed to assess the long-term effects of bioactive compounds as a component of the whole diet.","PeriodicalId":476095,"journal":{"name":"HERALD OF SCIENCE OF S SEIFULLIN KAZAKH AGRO TECHNICAL RESEARCH UNIVERSITY Veterinary sciences","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135428032","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
