Chemical, physico-chemical and sensory properties of soy-plantain flour

In recent years, research efforts in the developing countries have focused on the improvement of protein quality of food products due to mass malnutrition. Plantains are invaluable source of carbohydrate, comparable in nutritive value to yam or potato and are useful as a variant on the usual staple foods. It is consumed mainly in Nigeria as snacks and it is gradually finding applications in weaning food formulation and...

Elaboration of blackberry (Rubus glaucus Benth.) jellies with native and modified banana starches (Musa ABB)

To diversify the use of tropical fruits such as “topocho” (Musa ABB) and blackberry (Rubus glaucus Benth.), jellies were formulated, and thickened with 20% of native starch (BS), and modified granular starch (GBS) starch from unripe “topocho” with, and without the addition of carboxymethylcellulose (CMC) using corn starch as control. A sensorial evaluation of the recipes was completed...

Rheological, moisture and ash content analyses of a gum resin from Commiphora Africana

  A gum resin was isolated from Commiphora africana. In order to assess its application to industry, it was subjected to rheological, moisture and ash content studies. For rheological studies, a rotational viscometer which had the ability to characterize both Newtonian and non-Newtonian systems was used. The gum resins from C. africana exhibited low shear stress even at high concentration of...

The effects of roasting temperatures on the rate of extraction and quality of locally-processed oil from two Nigerian peanut (Arachis hypogea L.) cultivars

  The effects of roasting conditions (time-temperature) on the rate of extraction and quality of oils from two peanut (Arachis hypogea L.) cultivars (namely, kampala and ex-Dakar) were investigated. The oils were extracted at 50 ml hot-water/250 g peanut paste. High extraction rates were obtained by roasting the peanuts at 140°C for 20 min with Kampala yielding the highest oil. Above 140°C/20 min...

Serum biochemical response of rats fed with Sclerocarya birrea juice extracts

  Sclerocarya birrea fruits are widely eaten in developing countries especially in rural areas and serve as nutrients supplements. However, they also contain phyto-toxin which may affect the normal functioning of the body. The present study examined the effect of feeding albino rats with S. birrea juice with respect to their body weight, liver and kidney biochemical parameters. The results showed...

Fatty acid profile of raw and cooked fish consumed in Bahrain

  The objective of this study was to determine the fatty acid profile of raw and cooked (grilled, curried and fried) fish commonly consumed in Bahrain. Four most popular species of fish were purchased from the local market in Manama city, the capital of Bahrain. Fatty acids in raw and cooked fish were separated and quantitatively determined by gas liquid chromatography (GLC) using standard methods. The findings...

Susceptibility of steeped and heat dried cowpea flour to fungal growth and aflatoxins production

  In vitro studies were carried out to determine the susceptibility of flours from steeped and heat dried cowpea to fungal growth and aflatoxins production. A 2 × 7 factorial experimental design with 2 levels of steeping time of cowpea grain in water (0 and 3 min steeping) and 7 levels of drying temperatures of the grains ranging from 35 to 120°C were used for flour production....

Microbiological assessment of stored Tilapia guineensis

  Microbiological analysis of Tilapia guineensis was assessed at two ice stored temperatures, -18 and 4°C, for 4 weeks. Bacteria and fungi counts decreased from 7.9 × 103 to 5.4 × 101 cfu/g for bacteria and 6.2 × 103 to 3.2 × 102 cfu/g for fungi in the samples stored at -18°C, while for the samples stored at...

Proximate and mineral composition of cocoyam (Colocasia esculenta L. and Xanthosoma sagittifolium L.) grown along the Lake Victoria basin in Tanzania and Uganda

  The proximate and mineral compositions of cocoyam (Colossian esculenta L. andXanthosoma sagittifolium L) grown along Lake Victoria basin in Tanzania and Uganda were analyzed. C. esculenta and X. sagittifolium samples were significantly (p < 0.05) different in terms of their proximate composition and mineral contents regardless of their country of origin. Proximate analyses...
