Retention of nutrients of pearl millet using conventional and solar cooking
Comparative estimation of nutrients of pearl millet was studied by adopting two methods of cooking, that is, conventional cooking on liquefied petroleum gas (LPG) stoves and solar cooking. Starch, total soluble carbohydrate, protein, calcium and iron were determined for raw, conventional and solar cooked pearl millet. It was found that retention of starch was 98.58% for solar cooked and 74.51% for conventional cooked...

Evaluation of antioxidant and hypolipidaemic effects of fermented Parkia biglobosa (Jacq) seeds in tyloxapol-induced hyperlipidaemic rats
Globally, fermented foods form an intricate part of the staple diet of people. This study investigated the hypolipidaemic potential of fermented seeds of Parkia biglobosa (African locust bean/iru), a popular condiment by supplementing (20% w/w) in animal feed. Animals (n=5) in six treatment groups received; standard rat diet (control); iru-supplemented feed; standard rat feed with tyloxapol administered...

Optimization of taste and texture of biscuit produced from blend of plantain, sweet potato and malted sorghum flour
Biscuits were produced from blends of plantain, sweet potato and malted sorghum flour. This study was carried out to evaluate the effect of varying the proportions of these flour mixtures on the taste and texture of the produced biscuits. Mixture response surface methodology was used to model the taste and texture of the biscuits with single, binary and ternary combinations of the three flours. The optimum taste and...

Evolution of biochemical and physical parameters of two fresh-cut fruits over storage at 4°C
Biochemical and physical changes of two types of fresh-cut fruits packaged in plastic containers and stocked at 4°C were studied over a period of six days. The first type of container was film-lidded and contained orange juice, pomelo, kiwifruit and orange slices. The second type was plastic-lidded and contained orange juice, apple, kiwifruit and orange slices. Color, vitamin C and carbohydrates changes were...

Effect of pretreatment on physicochemical quality characteristics of a dried tomato (Lycopersicon esculentum)
Tomato is highly perishable and drying is a convenient method of extending its shelf life and minimizing postharvest loses. During drying, some nutrients may degrade and thus affect general quality characteristics of the dried tomato. The effect of pretreatment in enhancing drying and product quality of dried tomato was investigated in this study. Slices of tomato were treated by dipping in (a) A solution containing...

Analysis of quality attributes of banana drinks blended with aqueous extracts of ginger
This study aimed to investigate the effect of ginger (Zingiber officinale) on the microbiological, physicochemical and sensory quality of banana (Musa spp .) drink. Production of banana juice was achieved with hot and unheated water extraction. The various juices obtained were supplemented with aqueous extracts of ginger in concentrations of 2.5 and 10%, stored and analyzed periodically for microbiological and...

Evaluation of extrudate from sweetpotato flour and tomato pomace blend by extrusion processing
Sweet potato flour and tomato pomace blend were used for the development of extruded products. The response surface methodology was adopted in the experimental design to investigate the effect of feed proportion (5-25% tomato waste powder), moisture content (13-17%), screw speed (275-325 rpm) and barrel temperature (120-140°C) on the quality of the extruded products. Regression equation describing the effect of each...

Effect of three processing methods on some nutrient and anti-nutritional factor constituent of Colocasia esculenta (Amadumbe)
Colocasia esculenta L. Schott (Amadumbe) is a major starchy food crop used in the rural areas in Kwazulu-Natal province, South Africa. Like most root crops, Amadumbe is rich in carbohydrate content with low protein and lipids. Preliminary screening of Amadumbe revealed the presence of some anti-nutrients (amylase inhibitor, trypsin inhibitor, oxalate, alkaloids, saponin, phytate and total phenols). The effect of...
