In recent years, the demand for snacks with optimal functional and nutritional properties has a dramatic increased; hence researching in this regard is considered as an essential task. Almond, is one of the nuts kernel and an important source of nutrients, especially fats, fiber, antioxidants, vitamins and minerals such as iron and calcium. Using this seeds nut in expanded products not only improves the nutritional properties but also it causes to produce a product with optimal functional features. As the screw rate and humidity level have a great effect on the properties of extruded products. In this study, defatted almond flour –corn flour blends (20 - 80) were extruded in a co-rotating twin-screw extruder. Response surface methodology using a central composite design was used to evaluate the effects of independent variables, namely screw rate (120–220 rpm) and humidity level (12–16%) on functional properties (water absorption index, water solubility index and oil absorption index). Based on the process optimization maximum water absorption is 6.54085, water solubility is 25.6472 and oil absorption is 3.09778 that was belong to the production of screw rate 209.17 rpm and the 14% humidity.

Objective: Ugali is an important meal in many parts of Eastern and Southern Africa and is typically prepared from a single staple food like maize, cassava, millet and sorghum or their composite. The objective of this study was to understand the perception of sensory parameters when varying ratios of maize (refined and unrefined) and sorghum flour when substituted with high quality cassava flour (HQCF) 80%, 60%, 40% and 20% in the preparation of ugali. Methodology: The samples of ugali prepared were randomly subjected to panelists to evaluate sensory attributes preferred most by panelists. Thirty semi trained panelists who were females and males aged above 18 years participated and gave information on sensory signals. The panelists evaluated the samples independently and recorded the rating of the samples in the sensory evaluation questionnaire. The sensory parameters of ugali assessed were color, cookerbility, taste, texture, aroma and general acceptability using a five point hedonic scale. Results: Ugali made from the blends of unrefined maize flour (Dona) and HQCF as well as sorghum flour and HQCF at the ratio of 20:80 and 20:80 respectively were highly acceptable by panelists (mean score < 3). Ugali made from refined maize flour (Sembe) blended with HQCF at ratio of 80:20 was also preferred by panelists (mean score < 3) as compared to ugali made from other ratios. The highly acceptability (mean score < 3) of the ugali was influenced by color, cookerbility, taste, texture, aroma. At these flour ratios the blends of flours resulted in increment of protein, fats and slightly decrease in starch content. Conclusion: Blending HQCF and cereals (sorghum and maize) flours improved the organoleptic and nutritional properties of ugali.

Flour Blends

Triticale is likely used in many countries in human consumption, due to its advantageous agronomical and nutritional properties mostly in blends. The baking quality of blends depends not just on the proportions of the used flours but also on their individual quality what can be influenced by fertilizer treatments. 22 flour blends were prepared with commercial wheat flour and triticale wholemeal flour in proportions from 0% to 100%. The triticale was treated with different amount of fertilizers (N30P30K30, N60P0K0). Changes of wet gluten contents and extensograph parameters of the blends were determined. The quality of blends significantly depends on the fertilizer treatment of triticale beside the proportions of the flours. When the N60P0K0 treated triticale was used in blends, wet gluten and extensibility values were significantly higher, but in case of resistant to extensions (Rmax) the N30P30K30 treated samples gave higher values. The measured values of wet gluten and extensibility were above the expected values (synergism), while in the case of resistance to extension the expected values were higher than the measured values (antagonism).

This study aims to assess the addition of rice and coconut flour blends on cookies formulation, composition and acceptability. For the cookie formulations the following ratios between coconut flour and rice flour were used: 100:0, 50:50, 30:70. Moisture, ash, fat, protein, total carbohydrates of raw flours and cookies were determined by AACC (2000) methods, while sensorial evaluation was carried out using a 9 points hedonic test. Coconut flour was characterized by a high content of ash (5.09%) and proteins (17.2%) comparatively to rice flour. Blending coconut and rice flours at different proportions led to cookies with enhanced protein, ash and fat content. Sensory analysis revealed that blends of rice and coconut flour can be successfully incorporated into gluten free cookies, resulting in products with pleasant flavor and taste. Coconut flour possesses good nutritional properties which could be utilized for value addition of baked goods.

Physicochemical And Functional Properties

This study explored the possibilities of some selected flour blends vis-a-vis the physicochemical and functional properties of wheat flour. Ten flour blends from potato starch, cassava, maize and soybean flours and wheat flour were made and evaluated for physicochemical, functional and anti-nutritional properties. The range of proximate values were for moisture (3.76%–6.67%), protein (4.33–8.96%), ash (1.35–1.96%), fat (3.37–4.88%), fibre (1.22–1.89%) and carbohydrate (78.35–84.94%), whereas wheat flour had moisture (9.45%), protein (11.31%), ash (2.54%), fat (3.78%), fibre (1.31%) and carbohydrate (73.90%). Cyanogenic glucoside, saponion and tannin contents increased with increase substitution of cassava and soybean flours. Pasting temperatures of flour blends ranged from 69.03°C to 78.83°C, while wheat flour had 78.05°C. Peak, hot paste, breakdown, setback and cold paste viscosities were 1514–2822, 1036–1597, 487–1225, 580–884 and 1616–2461 cp in flour blends compared to 2361, 1360, 1001, 1079 and 2439 cp of wheat flour. Substitutions with soy flour decreased the peak, hot paste, breakdown and cold paste viscosities but increased the pasting temperatures. L*, a* and b* values ranged from 78.56 to 87.65, −0.34 to 0.71 and 10. 95 to 13.50 in flour blends while the wheat flour varied significantly at 2361.00, 1360.00 and 1001.00. The nutritional and pasting properties of some of flour blends were closely related to wheat flour and may be used for bakery requirements.

Purpose – This study aims to assess the quality characteristics and acceptability of cookies from sweet potato–maize flour blends and to determine nutritional quality, color and palatability traits and to compare the effects with that of wheat cookies, so as to suggest a cost-effective production method to bakers and retailers. This would ensure food security, enhanced health, combat malnutrition problems and improve the production of the crops. Design/methodology/approach – Cookies were prepared by the method reported by Okaka and Isieh (1990), Abayomi et al. (2013), Onabanjo and Ighere (2014) with modification. Flour (200 g) from each sample of different flour blends was used for the experiment. Sugar (80 g) was creamed with margarine (100 g) until light and fluffy constituency was obtained using Kenwood chef with initial minimum speed, and the speed increased stepwise until the mark of 6 on the chef indicator was attained. Whole egg (60 g) was added, then followed by flour (200 g), powdered milk (20 g), baking powder (0.1 g) and salt (1 g) were added and mixed until a stiff paste (batter) was obtained. The batter was rolled on a floured board using a rolling pin to a thickness of 0.2-0.3 cm. The rolled batter was cut into circular shapes with a cutter and arranged on a greased tray and baked at 1500°C for 20 minutes. The cookies were brought out, cooked and packaged in cellophane bag until used for laboratory analysis. Findings – The results revealed that substitution of sweet potato flour with maize flour significantly (p < 0.05) reduced the protein from 6.8-4.4 per cent, moisture from 5.3-5.0 per cent, crude fibre from 3.4-2.5 per cent and fat from 9.8-8.5 per cent of the composite flours and the cookies. The ash and sugar contents were increased from 4.3-5.8 per cent for ash and 2.1-3.9 per cent for sugar with increase in sweet potato flour substitution. The calorific value of the cookies decreased from 457-397 cal/100 g as the percentage of sweet potato flour increased in the maize flour cookies. Sensory evaluation results showed that the colour, texture, taste and overall acceptability changed significantly (p < 0.05) with increase in sweet potato flour substitution. The optimum substitution level was 40 per cent; above this, the product becomes less acceptable to the consumer. Research limitations/implications – Fabrication and production processing machines that use sweet potato will be a great challenge. Originality/value – This research is of value to the bakery industry or retailers. The optimum substitution level of sweet potato flour was 40 per cent, and it appears to be a promising measure from the view of practicability. The relative ease of getting sweet potato flour makes it superior to other imported flour like wheat and in reducing cost of importation of wheat to Nigeria.

<p>The purpose of this research was to develop and evaluate a snack product (chin-chin) from composite maize-wheat flour blends enriched with edible palm weevil (<em>Rhyhnchophorus phoenicis</em>) paste. The maize-wheat chin-chin enriched with <em>R. phoenicis </em>were subjected to acceptability test using twenty member semi-trained panelist. The moisture, fat, protein and carbohydrate compositions of the snack samples had significant differences in their values. Sample 5M5R90W (containing 5% maize flour and <em>Rhyhnchophorus phoenicis </em>paste and 90% wheat flour) had the highest protein value of 19.05% while the least value 9.39% was obtained by sample 100M0R0W (100% maize flour alone). Sample 100M0R0W containing 100% maize flour also had the highest carbohydrate value of 75.24%. There was no significant difference in the ash and crude fiber contents of the chin-chin samples enriched with edible palm weevil paste. There were significant differences (P ≤ 0.05) in the functional properties of maize-wheat composite flour blends. Their wettability values ranged from 46.67 – 200 while the swelling index, bulk density and oil absorption capacity showed no significant difference in their values. The result of the mineral analysis showed phosphorus, magnesium and sodium had significant differences in their values in the range of 317.55 – 376.75mg/100g; 5.60 -13.60mg/100g;59.0 – 70.3mg/100g, respectively. There were no significant differences in the sensory attributes of the chin-chin samples. The result showed that an acceptable chin-chin product can be processed with the inclusion of the larva of edible palm weevil with maize-wheat composite flour to enhance the nutritional quality of the product.</p>
