Identification and characterization of microorganisms in cheese are important nutritional, food safety, and technological issues. During this study, Citrobacter braakii EC-PS1 and Macrococcus caseolyticus Li-PT1 bacteria strains, isolated on selective mediums from two artisanal cheeses, were identified by way of 16S rDNA gene sequence analysis. Their antibiotic resistance and NaCl stress tolerance were also determined M. caseolyticus Li-PT1 showed tolerance to 6.5% and 10% NaCl. The increasing NaCl concentration above 15% contributed to the decrease of viability in bacteria. The increasing NaCl concentration to 10% contributed to the decrease of viability in C. braakii EC-PS1 bacteria. The identified bacterial species exhibited different levels of resistance to the tested antibiotics C. braakii EC-PS1 showed resistance to chloramphenicol, ampicillin, and streptomycin, whereas M. caseolyticus Li-PT1 was susceptible only to two antibiotics (erythromycin, tetracycline) out of the eight tested.","PeriodicalId":7180,"journal":{"name":"Acta Universitatis Sapientiae, Alimentaria","volume":"5 1","pages":"94 - 107"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86685035","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}

The availability of this plant is limited to the spring season, and it is perishable immediately after harvest. Osmotic dehydration (OD) is verified as an effective pre-treatment to improve sustainability by reducing the water content of raw material with minimal negative effect on its nutritive and sensorial qualities. In this study, OD of wild garlic leaves in aqueous solution of sucrose and salt was analysed at three temperatures and after diverse immersion times. The effects of the processing time and temperature on the dry matter content, water loss, and solid gain were evaluated using response surface methodology and analysis of variance. Some components in the samples were determined before and after OD. The results showed that during OD, the dry matter content of wild garlic increased from 7.91 ± 1.08% to 51.51 ± 1.34%. The maximum achieved values for water loss (0.6189 ± 0.0146 g/g i.s.) and solid gain (0.2417 ± 0.0146 g/g i.s.) indicated a good dehydration level. In the osmotically dehydrated wild garlic, the amount of analysed minerals decreased, sodium and sugar increased, and the content of protein, cellulose, and fat did not change – compared to the fresh sample.","PeriodicalId":7180,"journal":{"name":"Acta Universitatis Sapientiae, Alimentaria","volume":"3 1","pages":"27 - 39"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74961402","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}

Hunger affects more than 800 million people worldwide. Furthermore, the non-consumption of food accounts for 8-10% of global greenhouse gas emissions. Therefore, food waste generation has significant environmental, societal, and economic consequences. The circular economy (CE) is an economic model that seeks to reduce waste and extend resource life. The purpose of this study is to examine and present the connections between the CE, the Sustainable Development Goals (SDGs), and food waste management. Food waste management is commonly regarded as an environmental issue. Still, it also offers vital economic and social benefits for sustainable development. The first section of the research looks at the function of food waste management in the transition to a circular economy. The second part of this study examines the SDGs in food waste management and circular economy. The findings revealed that the most significant connections and synergies between food waste management, circular economy practices, and SDG targets could be found in SDG 2 (Zero Hunger) and SDG 12 (Responsible Consumption and Production). Both goals have high scores for direct and indirect contributions.","PeriodicalId":7180,"journal":{"name":"Acta Universitatis Sapientiae, Alimentaria","volume":"93 1","pages":"51 - 66"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77271035","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}

Selenium supports growth, the immune system, the reproductive organs, thyroid and muscle function, has an antioxidant effect, and protects against free radicals. The recommended daily intake of selenium for adults is 55 µg/day, which cannot be covered with food alone in selenium-deficient areas. That is the reason why we chose as our research topic the production of functional food – in this research: milk – in which the selenium level has been elevated naturally. In our work, we supplemented six Holstein-Friesian cattle feeds with a daily 1, 2, 4, and 6 mg/individual organic selenium, and then we measured the selenium content by ICP-MS. With a selenium enrichment of 1 mg/day, a 60% increase in selenium content was achieved, as the selenium content of milk increased from 32.93 µg/kg to 52.79 µg/kg. With the 2, 4, and 6 mg supplementation, the milk contained 97.2, 182.69, and 231.31 µg/kg selenium respectively. The latter is seven times more than the selenium content of the control sample. We have developed a recommendation for the amount of naturally selenized milk that should be consumed for different age groups. In our opinion, milk with increased selenium content could contribute to improving the selenium status of the population.","PeriodicalId":7180,"journal":{"name":"Acta Universitatis Sapientiae, Alimentaria","volume":"7 1","pages":"84 - 93"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74772494","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}

Peaches are usually consumed fresh, canned, or dried and represent a great source of the essential nutrients. Osmotic dehydration is a well-known preservation method that relies on mild temperatures and requires low energy. Research conducted at the Faculty of Technology Novi Sad has introduced sugar beet molasses as an efficient osmotic solution for drying various food samples. In this research, peach samples were osmotically treated in sugar beet molasses, and the goal was to investigate the impact of different solution concentrations, temperatures, and immersion time on the mass transfer rate and the efficiency of treatment. The results have shown that the mass transfer rate during the osmotic treatment of peach samples in sugar beet molasses was the most intensive at the beginning of the process, at the highest solution concertation, and at the highest temperature. In accordance with the results, diffusion occurred most rapidly during the first three hours of the process; therefore, processing time can be reduced.","PeriodicalId":7180,"journal":{"name":"Acta Universitatis Sapientiae, Alimentaria","volume":"6 1","pages":"1 - 10"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74510996","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}

In this research, the GCMS-based metabolite profiling of an authentic sample of tongba was carried out, identifying various bioactive metabolites. Several biologically active components, such as glycoside, amino acids, fatty acids, and other long-chain hydrocarbon derivatives, terpenoids and phenol, were detected in tongba, which have therapeutic properties against various high-altitude illnesses. Probable biosynthesis routes of those compounds in tongba’s broth were also studied, where many similarities were noticed with the Japanese beverage sake.

The nutritional value of RS, the effect of RS on short-chain fatty acid (SCFA) production, the relationships between RS and colon function, and the relationships between food starch, dietary fibre, and RS content and colon cancer development are reviewed. It has been shown that the use of RS in foods may have some benefits. Resistant starch, digestion of resistant-starch-containing foods have a number of health benefits for colon function but appear to have less effect on lipid-glucose metabolism. It has a positive effect on colon bacterial activity, promotes the growth of beneficial microbes, and reduces the activity of enzymes that are harmful to the digestive system. Under the influence of RS, increased SCFA production lowers the pH of the colon and stimulates bile acid secretion. The decreased pH protects against colon cancer and inhibits the conversion of primary and secondary bile acids, which are cytotoxic to intestinal cells. At the end of the review article, the relationships between RS and the colon microflora, its use as a prebiotic, and the relationship between RS and glucose metabolism are analysed. It was found that the use of RS in the diet might have benefits as it shortens the time it takes food to pass through the colon and increases the amount of stool. It was also found that the physicochemical properties of foods can directly affect the amount of RS and thereby the blood glucose levels and insulin response.","PeriodicalId":7180,"journal":{"name":"Acta Universitatis Sapientiae, Alimentaria","volume":"30 1","pages":"57 - 83"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88545056","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}

In recent days, the consumption of high-added-value, honey-based products are increasingly coming to the forefront of interest, and thus huge efforts are being made by researchers/developers to elaborate honey variants with fortified biological value. Relevant human clinical trials have scarcely been accomplished; thus, the biological impact of honey and its derivatives has not been thoroughly revealed. In this work, we present our experiments on the development of a novel honey-based prototype and its plausible physiological impacts certified via human clinical trials. The investigated product was a newly elaborated honeydew-based prototype fortified with pumpkin, sea buckthorn, and inulin, which was subjected to a 13-week-long, double-blind, placebo-controlled human clinical trial. The prototypes were applied to 20 adult volunteers to establish the complex impact of the newly developed product. Conclusions drawn at the end of the trial were based on results of blood tests taken at diverse phases of the study. The positive physiological effects of consumption of the investigated products are underpinned by the fact that no significant elevations have been measured in terms of the blood glucose level and parameters featuring long-term blood sugar levels. Slight decrease of both LDL and HDL cholesterol levels were also experienced.","PeriodicalId":7180,"journal":{"name":"Acta Universitatis Sapientiae, Alimentaria","volume":"44 1","pages":"44 - 56"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91387539","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}
