A survey was conducted in District Dir Lower in Khyber Pakhtunkhwa Province of Pakistan. The survey was conducted through a properly structured questionnaire from March 13th to June 2nd, 2019 to determine the consumption of fish (i.e. Mahasheer, trout, catfish, Common Carp, Rohu, etc.) according to in educational levels, gender, per capita, based on species liking, size, time duration, the order of preference given by the people. The current survey results showed that fish consumption had no relation to the educational level because illiterate and educational males consumed 75.51 and 58.53% fish respectively. Similarly, the percentage for illiterate female was 66.67% and educational female was 55.17%. The per head consumption for lower class was 0.49 kg per year, followed by middle class 0.46 kg then upper class 0.37 kg per year. The percentage of persons consumed fish per month was 46.25% while it was only 8% a year. The people who avoided fish for its spines and the high cost were 50.75 and 31.25% respectively. It was observed that people know that fish eating can increase the eyesight, helps in high blood pressure and reduces the cardiac disease were 46.75, 13.25 and 25% respectively. It has been concluded that per head consumption was greater for the lower class followed by the middle and upper class. Most people of the district Lower Dir consume fish once a month while few people consume fish occasionally. The fish consumption has no relation with educational level because illiterate people consume more fish than educated people.","PeriodicalId":246770,"journal":{"name":"Research Journal of Food Science and Nutrition","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128689015","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 objective of this study was to determine the nutritional content of the grass and, hence, quantify their contribution to the animal feed so as to curb the unavailability of animal feed during the dry season. Both macronutrients and micronutrients were determined using flame photometry and atomic absorption spectrometric methods of analysis. The research investigates the mineral and anti-nutrients contents of Pennisetum pedicellatum grass. The anti-nutrients were determined using standard methods of food analyses. The mineral content of the sample showed a composition (mg/100gDW) of 11167 ± 3.82 sodium, 10850 ± 229.13 potassium, 108.3 ± 0.03 calcium, 28.3 ± 0.03 magnesium, 315.7 ± 0.03 phosphorus, 0.58 iron, 5.81 chromium and 4.07 nickel. However, copper, zinc and manganese were not detected in the sample. The anti-nutrient composition (mg/100 g DW) for oxalate, phytate, saponins, cyanide and tannins were 1.00 ± 0.0008, 3474 ± 0.0223, 56.00 ± 0.0035, 11.00 ± 0.0014 and 10.00 ± 0.0025, respectively. The anti-nutritional analysis reveals that the grass contains high amount of phytate and saponins and low oxalate content. The results revealed that the oxalic acid content of the grass is below the critical level while the phytate of the grass is above the critical level.","PeriodicalId":246770,"journal":{"name":"Research Journal of Food Science and Nutrition","volume":"130 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115422402","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}

This study sought to assess the effect of school gardens intervention in improving serum zinc, iron, and retinol levels of pre-school children in the early childhood center through diet diversity in Mulala ward, Makueni County, Kenya. A between-group quasi-experimental design study on a sample of 63 children was adopted. The intervention early childhood centres were giving vegetables and animal proteins to children from the school garden as part of the ten o'clock snack of porridge and lunchtime meal of maize and beans for six months while the control early childhood centres had the usual ten o'clock porridge and lunchtime maize and beans meal. Questionnaires were used to collect end line data on demographic, socio-economic, feeding practices, and diet diversity. Blood samples were also collected from the children and blood tests for zinc, iron, and retinol done. Blood tests for serum zinc and iron were analyzed by flame atomic absorption spectrophotometry, serum retinol was assessed by High-Pressure Liquid Chromatography. The mean dietary diversity score of the control and intervention groups was found to be significantly different at post-intervention (p-value = <0.001). A significant and positive correlation between the levels of serum hemoglobin, retinol, zinc and dietary diversity was observed among the intervention population (P-value =0.045, n= 31 R=0.363), (P-value =0.033, n= 31 R=0.384), and (P-value =0.048, n= 31 R=0.358).

Matured soursop fruits were processed into flour. Granola was prepared from blends of wheat and soursop flours using 90:10, 80:20, 70:30, 60:40, 50:50 of wheat flour to soursop flour (SSF), and 100% wheat flour as control. Samples were subjected to sensory evaluation within 30 minutes of production. Proximate analysis was carried out using standard methods. The samples were also stored for 3 weeks and evaluated at weekly intervals for total bacterial and fungal counts. Proximate analysis revealed an increase in moisture (5.21 to 7.22%), ash (1.25 to 1.79%), protein (9.56 to 12.62%), crude fibre (0.83 to 1.21%) and energy contents (418.64 to 422.22kcal) with decrease in fat (14.13 to 12.09%) and carbohydrate contents (69.02 to 65.07%) as substitution of wheat flour with soursop flour increased. Sensory analysis showed that colour, taste, texture and overall acceptability of the control granola were more preferred. Colour of control granola and sample substituted with 20% SSF were significantly (p<0.05) similar. Similarly, texture and overall acceptability of control granola and samples substituted with 10, 20 and 30% SSF were significantly (p<0.05) similar suggesting that wheat flour can be substituted with soursop flour at levels up to 30% for the preparation of granola. During storage, total bacterial counts (TBCs) and fungal counts (TFCs) were observed to increase for all granola samples. TBCs and TFCs of granola samples after 3 weeks of storage ranged from 6.00×103 to 7.00×103cfu/g and 5.00×104 to 5.20×104cfu/g, respectively. The samples presented adequate microbiological conditions and were within recommended safe limit of microbial guidelines. The findings of this study therefore show that soursop can be utilized in the preparation of granola with improved nutritional value over wheat flour thereby reducing wastage associated with soursop fruits.","PeriodicalId":246770,"journal":{"name":"Research Journal of Food Science and Nutrition","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128032077","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 crude ‘kpaakpa’ seed oil was extracted (using hexane solvent) and characterized. The result of proximate analysis showed the moisture content, ash, fat, crude fibre, protein and carbohydrate contents to be 11.18, 5.6, 37.92, 6.45 31.53 and 7.37% respectively for undefatted flour and 18.6, 6.8, 4.37, 1.99, 26.52 and 41.72% respectively of the defatted flour sample. The results of functional properties did not show a consistent behavior for all the parameters analyzed for both defatted and undefatted ‘kpaakpa’ seed. However, it showed that defatting operation increased most of the functional properties except for bulk density and wettability which increased in undefatted ‘kpaakpa’ seed flour.
