This study reviews and exposes the beneficial potential of tamarind whiles studying with empirical data its nutritional composition for proximate analysis. Indigenous to tropical Africa and naturalized to many regions of the world, the tree is seen in over 50 countries. Within Ghana and other parts of the world, tamarind is distinctively called by different vernacular names either referring to the tree or its product. Almost every part of the tree is used in one way or the other from food including beverage drinks, jams, and curries, to pharmaceutical, textile, timber, fodder, and as a fuel source. It is rich in vitamins, minerals and other proximate elements. Proximate composition of locally sourced fruit pulp showed high levels of fats and oils 51.39% and fibre 15.10% while other parameters like protein, ash, vitamin C and moisture were similar to test results from other countries. The tamarind plant has undoubtedly great potential based on its benefits, and uses.

These fruits have great potential as an alternative and commercially viable pectin source for the pectin industry. Physicochemical and rheological characteristics of B. aethiopum pectins are significantly affected by the extraction process which permits the isolation of tailored pectin of specific applications in the food industry. One important step in pectin recovery is its precipitation from the liquid extract and this can considerably impact the quality attributes of the final product. In this study the effects of precipitating solvents (isopropanol, acetone and 50/50 isopropanol-acetone) on the physicochemical and functionalities of pectin recently extracted from B. aethiopum fruit were investigated. Most of the results for the physicochemical characteristics were not statistically different however great variability was noticed in the functional and rheological properties of pectins precipitated with isopropanol (IPA), acetone (ACTN) and the 50/50 IPA-ACTN solvents. Isopropanol precipitated pectin exhibited statistically higher (p<0.05) emulsifying activity and a better gel sensorial property than the ACTN and IPA-ACTN precipitated pectins. Moreover, regardless of the precipitating solvent, high purity pectin with high viscosifying, emulsifying and gelling properties were obtained. Therefore, production of pectin from B. aethiopum fruit pulp must be governed by its intended use since extraction and precipitation processes isolate pectin samples with various functionalities. \u0000 \u0000 \u0000 \u0000 Key words: Borassus aethiopum Mart, isopropanol, acetone, precipitating solvent, solvent mixture.","PeriodicalId":8649,"journal":{"name":"Australian Journal of French Studies","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.5897/AJFS2020.1926","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45647895","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"文学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While other crops are being bred or fortified to increase their nutritional benefits of β-carotene and other micro nutrients required for healthy growth and care for immunosuppressed people, the value of pumpkins in this regard remains under researched. This study sought to determine the nutritional physico-chemical parameters of selected pumpkin cultivars grown in Uganda. The seeds of 14 cultivars of pumpkin from four agro-ecological zones of Uganda were grown under similar conditions. Their mature pulp was then analyzed for their proximate, mineral and carotenoid composition including glucose, starch, crude fibre, crude fat, ash, crude protein, moisture, iron, zinc, calcium, potassium, lutein, α-carotene, trans-β-carotene, cis-β-carotene, total carotenoid and total pro-vitamin A carotenoid content using standard procedures. The proximate, calcium, potassium and the carotenoid content varied significantly across all the accessions (P˂0.05) while the iron and zinc content did not vary significantly across all the accessions (P˃0.05) respectively. The results from the study show that pumpkin pulp is a good source of dietary fibre, protein, calcium, potassium, iron and carotenoids with pro-vitamin A activity. Therefore, pumpkin can be utilized in the food processing industry as a food supplement and for several other value addition avenues such as wine and flour production. \u0000 \u0000 \u0000 \u0000 Key words: Accession, carotenoid, cultivar, proximate, pumpkin, value addition.","PeriodicalId":8649,"journal":{"name":"Australian Journal of French Studies","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.5897/AJFS2020.1980","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46449112","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"文学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It aimed to assess the dietary potential, bioactive compound levels and antioxidant activities of the leaves and fruits of Capparis corymbosa, a plant food from Burkina Faso. Standard methods were used to assess the nutritional potential of leaves and fruits as well as the levels of bioactive compounds and antioxidant activities of leaf and fruit fractions. Levels of total sugar were 765.40 ± 134.67 mg/100 g for leaves and 2208.65 ± 194.55 mg/100 g for fruits. Protein levels were 22.722 ± 0.95 mg/100 g for leaves and 13.442 ± 0.91 mg/100 g for fruits. Both organs also had interesting contents of minerals and essential amino acids. Total phenolic levels ranged from 18.36 ± 0.90 g GAE/100 g to 16.46 ± 1.15 g GAE/100 g for leaves and from 4.58 ± 0.15 g GAE/100 g to 1.03 ± 0.31 g GAE/100 g for fruits while those of flavonoids ranged from 2.83 ± 0.23 g EQ/100 g to 2.08 ± 0.25 g EQ/100 g and from 1.78 ± 0.25 g EQ/100 g to 0.93 ± 0.41 mg EQ/100 mg, respectively for leaves and fruits. The butanol extraction fractions had the highest levels of polyphenols of both organs. Monitoring antioxidant activities using DPPH, FRAP and ABTS models showed that leaves and fruits displayed high antioxidant activities but leaves had higher antioxidant activities than the fruits. Antioxidant activity was correlated with total phenolic levels.

Enhancement of this inhibitory effect by the addition of superoxide dismutase (SOD) confirmed that ROS are generated by light irradiation and that the generated superoxide anions (O2-) and hydroxy radicals (•OH) promote induction of the Maillard reaction.

This study determined the food hygiene and safety knowledge and practices of 345 street food vendors (SFVs) in selected locations within Kiambu County, Kenya. Data collection was accomplished through face-to-face interviews using structured questionnaires and extensive observation using an assessment tool for observation of personal hygiene and food handling practices of SFVs and the condition of the vending environment. The results indicated that the majority of the SFVs were male (63.2%) with 38.1% of them having attained secondary school education. About 93% of the SFVs had not received any formal training on food hygiene and safety. Majority of SFVs handled food with bare hands (96.8%) or handled money while serving food without washing hands (86.1%). Few also practiced preservation with 78.3% storing foodstuff that required refrigeration at ambient temperatures while 22.3% stored leftovers without any form of preservation and sold them the following day. Whereas public health officers’ visits were found to significantly (P<0.0001) motivate SFVs to obtain a food handler's medical certificate, only about 27% had obtained it.
