Extruded flakes from pearl millet (Pennisetum glaucum)-carrot (Daucus carota) blended flours-production, nutritional and sensory attributes

Open Access JournalMillet flour (M) and carrot flour(C) were produced and blended in the ratios 100M:0C, 95M:5C, 90M:10C, 85M:15C and 80M:20C respectively to produce extruded flakes. The composite flours were subjected to analysis of the proximate and mineral composition, as well as functional and pasting properties. Extruded flakes were analyzed for proximate composition, total carotenoids, colour and sensory evaluation. There was no significant difference (p > 0.05) in the proximate, functional and pasting properties but there were significant differences (p 0.05) affected by extrusion cooking. In terms of the lightness (L*), redness (a*) and yellowness (b*), 100% millet flakes had the least values of 50.09, 0.076 and 10.39 respectively. Sample with 85M:15C had the overall acceptance score of 7.25. In terms of colour and taste, the sample with 90M:10C had the highest scores of 8.50 and 6.50 respectively. Sample with 85M: 15C was most preferred in terms of crunchiness. The results indicate that pearl millet and carrot are rich in different nutrient when blended in the right proportions to make composite flour, it would produce nutrient-dense food product rich in protein, vitamin Aand minerals

Quality attribute of plantain (Musa paradisiaca) sponge-cake supplemented with watermelon (Citrullus lanatus) rind flour

Open Access Journal; Published online: 07 July 2019his study is aimed at supplementing Watermelon rind flour (WF) into cakes production with Plantain Flour (PF). Six cake samples were produced from the composite mixture of PF and WF in varying proportions of 100:0, 90:10, 80:20,70:30, 60:40 and 50:50. The composite flour of plantain-watermelon rind was evaluated for proximate, functional and pasting properties while the cakes were assessed for proximate, texture and sensory qualities using laboratory standard methods. The water absorption capacity (WAC) of the composite flours has a significant (P < 0.05) increase as the volume of WF increases from 0 to 50%. Cake produced from PF substituted with 50% WF has the highest value of protein (10.58%). The substitution of 10% of WF showed the highest score rating by the panelist in overall acceptability (7.60). This study has provided the recipe for the formulation of quality cake with PF and WF that could be acceptable by consumers

Evaluation of nutritional and functional properties of plantain (Musa paradisiaca L.) and tigernut (Cyperus esculentus L.) flour blends for food formulations

Open Access Journal; Published online: 28 Sept 2017Some individuals are intolerant to gluten of wheat and other cereals like oats, rye and barley used for food formulations and this intolerance seriously impairs intestinal absorption. There is need to develop alternative gluten-free flours for baking and confectioneries. This research therefore aimed at determining the chemical and functional properties of plantain–tiger nut composite flour to be able to explore its potentials in food formulation. The flours made from matured plantains and tiger nuts were blended at the ratio of 100:0, 70:30, 60:40, 50:50, 40:60, 30:70 and 0:100 to make different plantain–tiger nuts flours and these were analysed using standard methods. The results revealed that protein ranged from 4.55 to 6.78/100 g, fat (2.25–32.75/100 g), crude fibre (3.50–6.13/100 g), bulk density (0.81–0.92 g/cm3), swelling power (38.38–2.37/g), Mg (30.65–49.08 mg/100 g), P (3.65–120.65 mg/100 g), K (71.62–212.08 mg/100 g), Vitamin C (3.18–5.30 mg/100 g) and Vitamin A (1.71–51.31 μg/100 g). There were significant differences (p < 0.05) in the pasting profile of the plantain–tiger nut flour blends and in functional properties of composite flour except for bulk density. Addition of tiger nut flour improved the proximate, mineral and vitamin composition of the composite flour and the study concluded that inclusion of tiger nut flour is a good protein, fat, mineral and vitamin supplement for plantain flour

Quality evaluation of snack produced from black pepper (Piper nigrum L.), plantain (Musa paradisiaca L.) and tigernut (Cyperus esculentus L.) flour blends

Open Access Journal; just-acceptedChinchin has been identified to be one the favoured food items and a much-relished pastry which has been eaten as dessert or snack. This study aimed at evaluating the nutritional quality and organoleptic properties of black-pepper enriched Chinchin produced from plantain-tigernuts composite flour. Matured plantains (Musa paradisiaca), tigernuts (Cyperus esculentus) and black pepper were processed into flour. Chinchin was processed from different blends of plantain and tigernuts composite flour at the ratio of 100:0, 70:30, 60:40, 50:50, 40:60, 30:70, and 0:100 for plantain and tigernuts respectively. Five percent (5%) black pepper spice was added to each of the samples for Chinchin production. Proximate, mineral and vitamin compositions were determined using standard methods. The results of proximate composition of the different snack samples showed significant differences (P<0.05) with values ranging from 6.50-10.00%, 4.45-6.75%, 2.25-32.75, 1.33-2.00%, 3.50-6.13% and 46.07-78.48% for moisture, protein, fat, ash, crude fibre and carbohydrate contents respectively. There was significant difference (p < 0.05) in the minerals and vitamins contents, and organoleptic properties of the black pepper chinchin samples. In conclusion, chinchin of improved and acceptable nutritional and organoleptic properties could be obtained using plantain-tigernuts composite flour and black pepper spice for improved nutrition. This product could add to range of snacks available for those with special dietary needs

Proximate composition and physical properties of steamed sour cassava starch bread

The effects of steaming (10min, 20min and 30min) on the properties of sour cassava starch bread were evaluated. Properties examined include pH, moisture content, protein, ash, starch, sugar, amylose content and sensory analysis. Amylose content ranged between (14.04-15.73%), Amylopectin ranged between (84.27-85.96 %), protein content ranged between (3.85-4.18%), Starch and Sugar content ranged between (68.07- 69.01%) and (10.12-10.34%) respectively. As the level of steaming increases the fat (11.64-12.59%) and protein content (3.85-4.18%) increases. 10min-steamed bread was adjudged the best for sour cassava starch bread production as its bread had the highest score for overall acceptability (6.0) and other sensory parameters evaluated
