Proximate composition, nutritive and sensory properties of fermented maize, and full fat soy flour blends for “agidi†production
Composite flours containing 100:0, 85:15, 80:20 and 70:30 fermented maize and full fat soy flours, respectively were prepared. The effect of the soy flour supplementation on the proximate composition and nutritive values of the blends were evaluated. “Agidi”, a maize based fermented food product produced from the blends were subjected to sensory evaluation. The result shows higher protein contents (16:55,...

Spirulina platensis biomass cultivated in Southern Brazil as a source of essential minerals and other nutrients
The aim of this study was to determine elemental constituent of microalgal biomass Spirulina platensis LEB-18 grown on the shores of Mangueira Lagoon, South of Brazil. The spread of inoculum was performed in standard Zarrouk medium. When the microalgae concentration reached 0.50 g L-1, the biomass was separated by filtration and dried in a tray dryer at 50°C for 5 h. The harvested biomass was then ground in a ball...

Comparison between gamma irradiation and plasma technology to improve the safety of cold sliced chicken
The aim of this study was to determine the impact of gamma irradiation and plasma treatment on quality (appearance, odor and texture) and safety (total bacteria count, psychrophilic bacteria, spore forming bacteria, total molds and yeasts) of cold sliced chicken. Pulsed atmospheric-pressure plasma jet (PAPPJ) device is used for the treatment of fresh sliced chicken with different exposure time. Also, another sliced...

Determination of cyanogenic glucosides in cassava products sold in Okada, Edo State, Nigeria
Cyanogenic glucosides in some cassava products (cassava flour, fufu and garri) obtained from the market in Okada town, Edo State, Nigeria were determined. The cyanide content of the samples determined ranged from 5 to 10 ppm and falls within the acceptable limit of 10 mg HCN equivalent/kg dry weight recommended by FAO. Fufu product has the highest cyanide concentration of 10 ppm while garri has the lowest value of 5...

Some quality parameters of crude palm oil from major markets of Douala, Cameroon
Palm oil is the major cooking oil in Cameroon, and crude palm oil (CPO) is an essential ingredient of many local recipes. However, the quality of this foodstuff is subject to doubt, considering the very often inadequate conditions of its extraction and storage in the fast growing small holder sector. In order to assess the quality of (CPO) available to Cameroonian consumers, 40 samples of this product were randomly...

Comparative evaluation of the nutritional and sensory quality of different brands of orange-juice in Nigerian market
The physico-chemical properties, vitamins, minerals, microbial and sensory qualities of four different brands of orange-juice (samples A, B, C and E) in the Nigerian market were evaluated to determine their overall quality. Results of the physico-chemical properties obtained show the following range of values for acidity (0.40 - 1.06%), total solids (5.50 - 11.80%), total sugar (9.15 - 13.39%) and fruit juice content...

Microbial, biochemical and sensorial quality assessment of Algerian farmed tilapia (Oreochromis niloticus) stored at 4 and 30°C
The quality of Nile tilapia (Oreochromis niloticus) produced in Algeria was assessed after refrigerated (4°C) storage as well as ambient temperature (30°C) keeping, corresponding to usual fish selling conditions in Algeria. Sensorial, microbial and biochemical analyzes were conducted in parallel. Moreover, the nutritional quality of fresh tilapia was also assessed by determining the proximate composition and the...

A study on evaluation and characterization of extruded product by using various by-products
Broken rice flour was added in proportions (75%) to equal amount of dehydrated pineapple waste pulp powder and red gram powder (12.5%) were extruded in a twin-screw extruder. The formulation was extruded at different moisture content (17-21%), screw speed (260-340 rpm) and die temperature (120-140°C). The lateral expansion, bulk density, water absorption index, water solubility index, hardness and sensory...
