Freshly harvested seeds obtained from a local market in Ibadan were decorticated and cleaned of all extraneous matter. The kernels obtained were milled and graded into fine and coarse aggregates. The experiment was a central composite design in which two levels of moisture content (17 and 21%wb), heating temperature (50 and 70 ̊C) and time (5 and 15 mins) were considered. The data obtained were analyzed using Design Expert Version 6.0.8. The results showed that oil point pressure increased with time but decreased as heating temperature and moisture content increased. For fine aggregates, the minimum oil point pressure of 0.116 MPa was obtained at a temperature, time and moisture content combination of 60 ̊C, 10 mins and 23%wb, respectively. However, for coarse aggregates, the minimum oil point pressure of 0.144 MPa was obtained at 70 ̊C, 5 mins of heating time and moisture content of 21% (w.b). The results showed that the oil point pressure of fine aggregates was lower than that of the coarse aggregates. From the analysis of variance, heating time had significant effect on the oil point pressure (p<0.05). The minimum oil point pressure of calabash nutmeg was obtained as 0.116 MPa at an optimal temperature, time and moisture content of 64 ̊C, 5 mins and 21% (w.b), respectively.","PeriodicalId":199134,"journal":{"name":"European Journal of Food Science and Technology","volume":"26 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140507769","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 study was carried out to determine and to compare total aflatoxin levels in groundnuts sold in Lagos markets, Nigeria. Microbiological and toxicology tests were carried out on raw, boiled, and roasted groundnuts from the same source. The microbiological test was carried out to detect the fungi that produce aflatoxins as their secondary metabolite. The groundnuts samples were cultured on Potato Dextrose Agar (PDA). The isolates were identified using standard microbiological methods, characteristics such as presence of spores, shape, colour of spores and presence of septa were used in identification. Aspergillus flavus (75%; percentage of occurrence) was the most frequently isolated fungus from the groundnut samples. The other contaminant isolated from the samples were Aspergillus niger (25%). The toxicology analysis was carried out to determine the production of aflatoxins and the level present in the groundnut. This was carried out using a Romer Mycosep Column kit for aflatoxin to clean-up, and High-Performance Liquid Chromatography (HPLC) to detect the aflatoxins and determine the levels. Total aflatoxins were detected in the groundnuts, and they ranged between 0.36 ppb and 0.42 ppb. The levels of total aflatoxins were not beyond the regulatory standard of National Agency for Food and Drugs Administration and Control- NAFDAC (for ready to eat food, 4µg/kg while food that will still undergo processing 20µg/kg). Thus, the groundnut samples from the four markets are fit for consumption.","PeriodicalId":199134,"journal":{"name":"European Journal of Food Science and Technology","volume":"11 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140508507","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}

Several numbers of scholars have made investigation on PSNP to know the effect of it on livelihood outcome and the obtained results were contradicted (positive, negative and no effect). Hence, this meta-analysis was aimed to direct and quantify the effect of safety net program on livelihood outcome (food security, income, asset accumulation and livestock holding) from the literature with productive safety net program. Based on inclusion and exclusion criterion, 20 studies published from 2011 to 2022 were included during this meta-analysis. Random effect model was used to evaluate the effect size of productive safety net intervention on farmer’s outcome in Ethiopia. Results of random effect model confirmed that program intervention were positive and significant effect on food security. Therefore, policy makers and other stakeholders should expand productive safety net program in rural areas which exaggerated with natural disaster in Ethiopia.","PeriodicalId":199134,"journal":{"name":"European Journal of Food Science and Technology","volume":"19 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140507377","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 ingredients used in the soup preparation were melon / egusi seeds (Citrillus lanatus), achara/ elephant grass (Pennistetum purpureum), meat, crayfish, usu, Ukazi (Gnetum africanum), stock fish, snail, pepper, and palm oil and they were purchased at watt market, Calabar. It was an experimental study and the soup was prepared using standardized recipe in Nutrition and Dietetics Laboratory. Amino and fatty acid content of the soup meal were determined using standard methods. The fatty acids composition revealed the predominance of saturated fatty acids; palmitic acids and stearic acid (30.02%) and 27.03%) in the soup meal, and some unsaturated fat such as Poly n-6, and Oleic acid (23.50% and (20.10%) respectively. The Amino acid profile revealed that the soup is rich in protein (essential and non essential amino acids). The concentration of glutamic acid was seen to be highest (13.63±0.01), followed by Aspartic acid (8.46±0.00), Lysine (6.52±0.01), Leucine (6.36±0.01), glycine (5.81±0.01) and Arginine (5.59±0.00) respectively, Based on the findings it was concluded that the level or amount of saturated fatty acids (palmitic and stearic acids) in the soup meal were high and this can be detrimental to health because saturated fats increases the level of Low density lipoprotein which contributes to the risks of having heart diseases such as hypertension. It was also discovered that the increase level of the saturated fat in the soup was as a result of the quantity of palm oil and melon used in the preparation. However, the fatty acid component were of plant origin, so are easily broken down. Therefore, it is advisable that a moderate lesser quantity of melon and palm oil should be used in the soup preparation in order to reduce the level of saturated fat. It was also discovered that the amount of amino acid content in the soup was commendable and there was no variation or difference with the concentration of amino acids (essential and nonessential amino acids) in Hen’s egg which is recommended by FAO as a source of complete protein. Hence the soup meal will contribute in alleviating occurrence of diseases related to protein deficiency such as kwashiorkor, marasmus, and protein energy malnutrition to it consumers and likewise contribute in meeting the nutritional requirement of human growth and development.","PeriodicalId":199134,"journal":{"name":"European Journal of Food Science and Technology","volume":"169 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115004935","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 treatment of inflammation is generally based on chemical drugs. Nutritionists recommend the use of food plants that might have anti-inflammatory effects. So, the phenolic compounds, chemical composition, acute toxicity, in vitro and in vivo anti-inflammatory activities and pain-relieving activity of a recipe extract based on the leaves extract of three food plants (Ceiba pentandra, Ipomoea batatas and Spinacia oleracea) were evaluated. The results showed that the yield of extraction was 20.7 % and revealed the presence of polyphenols (821.6 mg/100 g) and flavonoids (99.8 mg/100 g). The chemical composition gave: proteins 0.023 %, lipids 0,011 %, ash 0.013 %, fibers 0.011 % and assimilables carbohydrates 0.026 %. The acute toxicity test did not cause any mortality, nor any sign of toxicity at the dose of 5000 mg/Kg/bw. In vitro anti-inflammatory test showed that the plants extract, at the concentrations of 150 and 250 µg/mL had an inhibitory effect, respectively of 65.63% and 86.97%. For in vivo anti-inflammatory test, at the doses of 400 and 800 mg/Kg/bw, the extract has an optimum inhibition of 79.95% and 53.62%, on a mice paw edema, at the fourth hour after injection. The pain test showed inhibitions of 94.74%; 98.25% and 100% at the respective doses of 300, 600 and 1200 mg/Kg/bw.
