This investigation aimed to estimate the nutraceutical Effectiveness of olive and turmeric oils against paracetamol-induced hepatotoxicity in experimental rats. Twenty Sprague-Dawley male albino rats weighing 200±10 g each, were randomly divided into four groups; five rats each as follows; the first group was control negative (C -ve), the second group induced with liver intoxicated by paracetamol then fed on basal diet ( C +ve), the third group induced with liver intoxicated by paracetamol then fed on basal diet concurrently with orally administered of olive oil at a dose of 1 ml/kg body weight., and the fourth group induced with liver intoxicated by paracetamol then fed on basal diet concurrently with orally administered of turmeric oil at a dose of 1 ml/kg body weight. At the finale of investigational period 28 days, blood samples were collected for determination the following parameters; TC, TG, HDL, LDL VLDL, AI, glucose, TP and Alb. Moreover, BWG, FI and FER were calculated. The findings showed that all rats in the experimental groups orally injected with olive oil and turmeric oil at a dose 1 ml/kg body weight, each displayed a notable decline in TC, TG, LDL VLDL, AI, glucose, TP and Alb.

Consequently, this study strives to assess the probiotic capacity of Lactobacillus strains obtained from artisanal dairy products and select promising candidates for potential use as innovative food preservatives or probiotic additives in functional dairy products. The in vitro examinations encompassed survival under acidic conditions and exposure to bile salt, as well as assessment of antimicrobial activity against Bacillus cereus , Staphylococcus aureus , Escherichia coli O157:H7, and Salmonella typhimurium . Tolerance to 0.4% bile salt and exposure to pH 2.0 acidity were first determined, and subsequently assessed other probiotic characteristics. From the pool of 422 isolates, 25 displayed notable resistance to both acid and bile salt, and from this group, only five isolates were selected for more detailed characterization. Phenotypic methods were used for their characterization, and through 16S rRNA gene sequencing, they were identified as two distinct species: Limosilactobacillus fermentum (3 isolates) and Lactiplantibacillus plantarum (2 isolates). The 5 isolates exhibited varying degrees of antimicrobial effectiveness against pathogenic strains. Considering all the experiments, all strains appear to be promising candidates for utilization in food preservation and/or as probiotic supplements in functional food.","PeriodicalId":470908,"journal":{"name":"Journal of Food and Dairy Sciences (Print)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136359743","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}

Polysaccharides from sesame hulls, with a yield of 6.49%, were separated into three distinct fractions using column chromatography. These fractions were then analyzed for their primary components and their potential to lower blood sugar levels. The major fraction, Pol-1, accounting for 1.74% of the total, contained components such as rhamnose (9.3%), glucose (9.2%), glucuronic acid (14.1%), and galacturonic acid (50.4%), along with other constituents. Our results revealed that varying concentrations of these polysaccharide fractions significantly influenced the reduction of glucose diffusion and the inhibition of both α-amylase and α-glucosidase activities. Notably, Pol-1 exhibited the most substantial inhibitory effects on both enzyme activities, as well as a notable decrease in glucose diffusion rate. These effects have the potential to extend the blood glucose response and regulate postprandial glucose levels. Consequently, sesame seed hull polysaccharide fractions hold promise for improving blood glucose regulation and could find applications in functional foods.","PeriodicalId":470908,"journal":{"name":"Journal of Food and Dairy Sciences (Print)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136073560","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}

These puree blends with 15 g sugar, 0.3 ginger, and 3ml lemon juice. The leather samples were analyzed for chemical composition, physical, organoleptic properties, and microbiological contamination. The findings revealed that as the increasing of levels of tamarind puree the moisture, ash, fiber, and total sugar contents were increased but protein, fat, and carbohydrate were decreased. Furthermore, β–carotene was decreased but vit c and titratable acidity were increased so, the PH value was decreased. Moreover, minerals content such as Ca, K, P, Mn, Mg, and Na were increased. Besides, the total phenolic content and DPPH radical scavenging activity were increased. TSS was decreased by increasing the level of tamarind puree. The leather sample containing 25% tamarind had the highest value of L* (lightness), a * (redness), and b* (yellowness) color compared to other samples. Texture profile such as hardness was decreased but the cohesiveness, springiness, gumminess, and chewiness were increased. Similarly, sensory properties such as color, odor, flavor, taste, and overall acceptability were increased, so the leather sample containing 100% tamarind had the highest overall acceptability compared to other leather samples.
