Genotoxicity and anti-genotoxicity of fennel plant (Foeniculum vulgare Mill) fruit extracts using the somatic mutation and recombination test (SMART)

The antigenotoxic action of fennel (Foeniculum vulgare) were assessed using the eye (w/w+) somatic mutation and recombination test (SMART) assay of Drosophila melanogaster. Fennel is used for various medicinal purposes. Methyl methanesulfonate (MMS) was used as the positive control. Fruit extracts of fennel did not show genotoxicity at the doses used. In the co-treatment, a dose-dependent decrease in mutation...

Comparisons of physiochemical, total phenol, flavanoid content and functional properties in six cultivars of aromatic rice in Bangladesh

  Various aromatic rice varieties such as Kalizira, Begun Bichi, BRRI dhan-34, BRRI dhan-37, BRRI dhan-50, Philipine Katari were analyzed for physiochemical, total phenol, flavonoid contents and functional properties. All aromatic rice varieties had moisture contents (11.25 to 15.13%), protein (3.23 to 6.21%), fat (0.68 to 1.45%) and ash (0.88 to 1.46%). The maximum amount of amylose and...

Mycoflora of fresh shrimps (Penaeus aztecus) from different markets in Port Harcourt, Nigeria

  Fungi were isolated from fresh brown shrimps (Penaeus aztecus) purchased from three different markets in Port Harcourt using standard mycological methods. The total counts of heterotrophic fungi range from 2.0 x 104 spore forming units per gram (sfu/g) to 7.1 x 104 sfu/g, while the total counts for pathogenic fungi range from 1.7 x 104 sfu/g to 7.1 x 104 sfu/g. The heterotrophic fungi and...

Comparative studies of physico-chemical properties of yam (Discorea rotundata), cocoyam (Collocasia taro), breadfruit (Artocapus artilis) and plantain (Musa parasidiaca) instant flours

  Cocoyam, breadfruit and plantain usage is similar to that of white yam. They offer similar and sometimes better nutrition advantage to yam though with less prestigious value. This study is aimed at producing instant flour of yam, cocoyam, breadfruit and plantain and to compare their physico-chemical properties. The instant flours were prepared separately with slight modifications. Proximate analysis, starch,...

Development of nutritionally enriched instant weaning food and its safety aspects

  Malnutrition is persisting among children in Bangladesh due to lack of proper weaning foods. A highly nutritive instant weaning food was prepared in our laboratory by using locally available food resources with the aim to ensure the availability of low cost weaning food in Bangladesh. The developed food was evaluated for their nutritional characteristics and microbiological quality. The food contained the...

Changes in quality attributes of mixed roselle, water melon and grape juice using Aframomum danielli as a preservative

Roselle, water melon and grape juice are excellent sources of vitamin C. The shelf life of most fresh fruit juices stored under room temperature is very short. The use ofAframomum danielli (A. danielli) as a preservative is not known. Roselle juices processed at 1:1 and 1:2 with or without A. danielli of 15% concentration were stored for two weeks at room temperature and evaluated for chemical properties...

Microbiological quality assessment of some National Agency for Food and Drug Administration and Control (NAFDAC) approved fruit juices sold in Ilorin metropolis

  This study was carried out to investigate on the microbiological qualities of some NAFDAC approved fruit juices sold in Ilorin metropolis. The brand of fruit juices assessed was coded as LL, LC and LB. The total viable counts, associated microorganisms and physicochemical properties of 10 randomly selected samples from each of the brand were determined. The highest mean bacterial load of 7.8 cfu/ml was found...

Proximate composition and microbiological study of five marine fish species consumed in Gabon

The aim of the current study was to determine proximate composition (protein, lipid, ash and moisture), energy and microbiological spoilage in five fish species. The chemical analysis revealed that the protein content of Pseudotolithus typus was 19.19%,Pomadasys peroteti 16.05%, Galeoides decadactylus 17.15%, Carassius auratus20.78%...

Proteolysis of milk heated at high temperatures by native enzymes analysed by trinitrobenzene sulphonic acid (TNBS) method

  Native enzymes play a significant role in proteolysis of milk during storage. This is significant for heat resistant native enzymes. Plasmin is one of the most heat resistant enzymes found in milk. It has been reported to survive several heat treatments, causing spoilage during storage. The aim of this study was to assess susceptibility of high temperature heated milk to proteolysis by native...

Nutritional qualities and trace metals concentration of six fish species from Oba reservoir, Ogbomoso, Nigeria

  The nutritional qualities and concentration of trace metals (Pb, Fe, Cu, Zn, and Cd) in six fishes (Hemichromis fasciatus, Siluranodon auritus, Sarotherodon galileaus, Tilapia zilli,Chrysichthys nigrodigitatus, and Hepsetus odoe) obtained from Oba reservoir in Ogbomoso, Nigeria were evaluated. The value ranges of 55.95 to 68.80, 16.91 to 26.18, 5.46 to 18.18, 0.51 to 9.05, 7.67 to 10.14 and...
