Defatted and undefatted samples of ‘kpaakpa’ (H. barteri) seed flours were produced. The mineral, vitamin and anti-nutrient composition of the flour samples were determined. Results of mineral composition showed calcium, copper, iron and potassium contents to be 30.00 mg/100g, 0.84 mg/100g, 3.67 mg/100g and 1.62 mg/100g, respectively, for the defatted flour; 27.33 mg/100g, 0.68 mg/100g, 0.86 mg/100g and 2.40 mg/100g, respectively for the undefatted flour sample. For the defatted flour, high calcium content indicated that the seed could be a valuable calcium supplement, especially, in calcium deficient diets. Furthermore, results obtained for vitamin A, vitamin D, vitamin E and vitamin K were 1769.13 µg/100g, 8.25 µg/100g, 67.85 mg/100g and 10.31 mg/100g, respectively for the defatted flour and 5759.10 µg/100g, 15.87 µg/100g, 78.50 mg/100g and 11.53 mg/100g for the undefatted flour. The high vitamin A content revealed that the seed could be a good supplement for foods with low vitamin A and could be a remedy to blurred vision. The results of the anti-nutrient determination showed that the composition of phytate, oxalate, tannin and cyanide of defatted seed flour were 0.37, 0.14, 0.93 and 0.04%, respectively and 0.34, 0.05, 0.60 and 0.06% for the undefatted seed flour. The low anti-nutritional content particularly cyanide makes the seed more suited for food formulation.","PeriodicalId":246770,"journal":{"name":"Research Journal of Food Science and Nutrition","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128982757","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}

Due to this huge discrepancy and lack of data, there was a dire need to establish age appropriate BMI ranges for Pakistani population. The basic aim of the study is to find out the BMI ranges among the school going children/adolescents of Karachi Pakistan. A cross sectional study was conducted among children belonging to different ethnic groups in primary, middle, secondary schools and Maddarsa (religious educational institutes) of Karachi. Height in centimeters (cm) and weight in kilogram (kg) were measured. BMI was calculated using height and weight. WHO’s BMI graph was used to find out the percentile for labelling underweight, normal healthy individual, overweight and obese. A total of about 1244 samples of children and adolescents aged seven to eighteen years were included. The mean age of the study participants was 12.96±2.8 years, in which boys having mean age of 13.1±2.7 years while for girls mean age was 12.66±2.8 years. The mean height (cm) and weight (kg) among the study participants were 146.92±15.84 and 41.20±15.69 respectively. Among younger age group, the girls were taller than the boys but after reaching the age of 15 the girls having approximately the same height up to the age of 18th and as for boys, the findings were vice versa. Majority of the participants reported normal BMI while for over abnormality, the higher prevalence of participants being overweight rather than underweight when comparing with the WHO references.

De-hulled seeds were boiled for 6 hours and fermented at 28oC, 35oC and 42oC for 96 hours. The amino-acid profile of raw, boiled and fermented BGS and MES were determined respectively. The protease activity of the seeds was as well determined at various stages of fermentation. The amino-acid profile of the samples showed high content of glutamic acid (152.1 to 158.8 mg/g for BGS and 145.4 to 166.7 mg/g for MES). Generally, the concentration of the respective amino-acids (essential and non-essential amino-acids) present in the seeds decreased with boiling but increased after fermentation. Fermentation was found to significantly (p<0.05) affect the protease activity of the seeds. The magnitude of the effect was dependent on the seed type, fermentation time and temperature. An increase in fermentation temperature from 28 to 42oC led to an increase in the protease activity of the respective seeds (15.8 to 23.8 units/ml for BGS and 21.6 to 23.0 units/ml for MES) which invariably resulted to the increase in the concentration of the amino-acids present in the respective seeds thereby increasing the bioavailability of the proteins present in the seeds. Microorganisms isolated and identified in the fermenting mashes include; Bacillus Subtilis, Bacillus cereals, Micrococcus luteus, Staphylococcus aureus and corynebacterium sp. The results showed that fermented BGS could favourably substitute for fermented MES as a source of cheap and affordable dietary protein.","PeriodicalId":246770,"journal":{"name":"Research Journal of Food Science and Nutrition","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129504224","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}

Replacing of chemical preservation with bio preservation strategies are user friendly and has great potential if constraints in production and application techniques studied completely. Among the various bio preservative plants, Aloe vera plant has a great history for its medicinal use against wide range of ailments and fruit preservation.

Ribosomal gene sequencing revealed that the Ivorian soumbara is associated with a wide microbial diversity essentially composed of 10 Bacillus species representing more than 90% of total microbial isolates, 3 species of lactic acid bacteria (2.48%), 2 species of Staphylococcus (1.42%), 8 fungal species (4.61%) and 1.06% of other microorganisms. However, the PCR-RFLP revealed a very weak intraspecific diversity as strains belonging to the same species showed a single restriction profile. Moreover, the microbiota associated with Ivorian soumbara consisted in a core and autochthonous microbiota namely B. subtilis and B. velezensis that were consistently present in samples from all regions studied and an incidental microbiota that was variable through the regions. Among the variable microorganisms, the presence of potential pathogen opportunistic such as Staphylococcus pasteuri, Staphylococcus sciuri and toxinogen species such as B. cytotoxicus and Aspergellus flavus were particularly found. The core microbiota is believed to be involved in the normal process of African locust beans into soumbara and can serve as potential starter whereas the incidental and variable microbiota rather undesirable may be involved in the spoilage or food-born disease. In this study, many species were described for the first time in soumbara, and revealed a new biodiversity of microbiota associated with soumbara in Cote d’Ivoire.","PeriodicalId":246770,"journal":{"name":"Research Journal of Food Science and Nutrition","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129151666","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}
