To enhance the distribution of marinades within the meat, mechanical processing of the raw material is necessary, specifically using the massaging process, to achieve uniform distribution of curing agents, changes in structure, and increased activity of enzymatic systems utilized in marinades. The main goal of this study is to model the massaging process, which allows the processing of the obtained experimental data in the form of a criterion equation. For the research, 8 samples were used, including 3 experimental pork samples and 1 control, as well as 3 experimental beef samples and 1 control. The main components of the samples include pork meat, beef meat, canola oil, sunflower oil, olive oil, curing ingredients, spices and seasonings, bromelain enzyme, and yeast extract. To carry out the massaging process in the investigated procedure, a massager of the model MAL 50-1500 was employed. The research results indicate that the determined mass transfer equation demonstrates a predominant influence in the investigated massaging process, involving changes in the concentration of sunflower, canola, and olive oil in the product, affecting the diffusion coefficient, size of dispersed phase particles, and mass transfer coefficient within the load.","PeriodicalId":20379,"journal":{"name":"Potravinarstvo","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135476221","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, the disposal of citrus waste poses significant environmental challenges. Orange peels (OP) are a substantial by-product of fruit processing and hold great potential as a source for bioethanol production, promoting investment in utilizing agricultural waste for biofuel purposes. OP offers a cost-effective substrate for producing value-added compounds, including bioethanol. Autoclaved-water treated OP biomass exhibited the highest release of reducing sugars (68.2%) this results supported by SEM images of that Autoclaving has definite effect on the structure of the OP particles. Among the five tested microbes, Candida tropicalis was selected as a promising bioethanol candidate due to its ethanol tolerance and ability to utilize xylose. Preliminary screening using Plackett-Burman Design (PBD) was conducted to identify six influential factors affecting the fermentation process at three levels, determining the optimum response region for bioethanol production by C. tropicalis. The significant variables were further investigated using Response Surface Methodology-Central Composite Rotatable Design (RSM-CCRD) at five levels, a novel approach in this study. The addition of cysteine and resazurin as reducing agents increased bioethanol production by 2.9 and 2.1 times, respectively, from the treated OP. Under the optimized conditions obtained from RSM-CCRD, bioethanol production reached 16.7 mg/mL per mg/ml reducing sugars. Implementing all the optimized conditions, including an initial pH of 5.75, 3% yeast extract, 2.25 g/L cysteine, 4% inoculum size, 0.6 g/L ZnSO4, 0.29 g/L MgSO4, 0.3 g/L MnSO4, and substrate treatment with active charcoal before fermentation, the bioethanol yield increased by 2.2 times after three days of fermentation using co-cultures of C. tropicalis and Kluyveromyces marxianus. The fermentation process was conducted at 30 °C and 150 rpm. Exploring OP as a low-cost renewable substrate and employing efficient microorganisms open new avenues for bioethanol production.","PeriodicalId":20379,"journal":{"name":"Potravinarstvo","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135933086","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}

Musculus semimembranosus and m. quadriceps femoris of the thigh and m. longissimus dorsi of the roast beef were used for analysis to evaluate the fatty acid profile. Chemical analysis of the thigh and roast beef muscle samples was performed using Fourier transform infrared (FTIR) spectroscopy. The measured data were statistically processed according to descriptive characteristics, analysis of variance, and differences were tested using Scheffe´s test at a = 0.05. The SAS program package, version 8.2, was used to evaluate the results statistically. A statistically significant difference (p ≤0.05) was recorded in the dry matter proportion between m. quadriceps femoris and m. longissimus dorsi. A statistically significant difference was found in the intramuscular fat proportion, polyunsaturated fatty acid proportion, the ratio of polyunsaturated fatty acids to saturated fatty acids, the ratio of polyunsaturated fatty acids to monounsaturated fatty acids, as well as between m. semimembranosus and m. longissimus dorsi and between m. quadriceps femoris and m. longissimus dorsi. Strong, statistically significant (p ≤0.01, p ≤0.001) correlations were found mainly between intramuscular fat and polyunsaturated fatty acids, between intramuscular fat and the ratio of the polyunsaturated fatty acids to saturated fatty acids, between intramuscular fat and the ratio of polyunsaturated fatty acids to monounsaturated fatty acids. In conclusion, it was stated that the muscles of the thigh and roast beef of the young cattle are characterized by statistically significant differences in the proportion of fatty acids. The ratio of polyunsaturated fatty acids to saturated fatty acids meets the recommended values concerning maintaining the health of the food consumer. Still, the ratio of the n-6 to n-3 polyunsaturated fatty acids poses a risk concerning cardiovascular diseases.","PeriodicalId":20379,"journal":{"name":"Potravinarstvo","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135932809","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 sample with a 1% addition was found to be rational according to the results of the organoleptic evaluation. The formulation was optimised in further study by selecting 0.5%, 1.5% and 2%. A centre composite plot was used to add points around the pre-lagged optimum. A regression formula was obtained, and the melting salts and the dosage of the added enrichment agent were determined. Also, the share of cheese from goat's milk in the recipe of processed cheese was determined. The recipe was calculated on the principle of material balance. Experimental samples were examined for fatty acid and amino acid composition. The tables compare the best sample on organoleptic evaluation with the control. It was found that when 3% is added, the cheese acquires a dark green tinge. The colour is deep green when 2% is added; when 1% or less is added, the colour is salad. The dose of melting salts in the recipe was reduced to 2%; in the classic recipe, it was 3.9%. The protein of the experimental sample turned out to be closer to the ideal protein.

Leptospirosis is a worldwide zoonotic disease caused by pathogenic Leptospira species. In general, leptospirosis has been registered in more than 150 species of mammals. There are about 300 serovars of Leptospira spp. Serovar Hardjo is one of the most common causes of leptospirosis among cattle globally. In cows, the infection can be completely asymptomatic or cause abortions, stillbirths, infertility, and mastitis. The study's relevance is determined by the negative impact on the economy – productivity loss, and high cost of medical-preventive activities. Leptospirosis also affects humans. In this regard, the present study aimed to determine the prevalence of antibodies to Leptospira interrogans serovar Hardjo in tank milk samples from cows selected from farms in different regions of Ukraine. The method of indirect enzyme-multiplied immunoassay was used for this problem to be investigated. We have investigated 114 tank samples from 66 Ukrainian farms, 63.2% positive, and 36.8% negative. It was established that antibodies to the causative agent of leptospirosis were recorded in different regions of Ukraine. It has been established that the largest number of positive samples was from Kyiv and Cherkasy regions.
