Background: Development of complementary foods by mixing plant-based (cereals, pulses, oilseeds, and others) ingredients and employing various processing techniques is widely reported. However, information on comparison of anti-nutritional factors and functional properties of extruded and unextruded complementary flours made from a multi-mix is limited. In this regard, this study aims to investigate the influence of extrusion cooking on anti-nutritional and functional properties of newly developed extruded oats, soybean, linseed, and premix composite complementary flours.Methods: Thirteen different blending ratios of oats, soybean, linseed, and premix were generated using a constrained D-optimal design of the experiment. Each of the 13 blends was divided into two groups: extrusion cooked and unextruded composite flour sample. Anti-nutritional and functional properties were determined using standard methods for both composite flours. ANOVA was used to determine if there was a significant difference for extruded and unextruded composite flours and paired t-tests were used to check variation between extruded and unextruded.Results: The phytate content of the extruded and unextruded composite flours was 158.93–191.33 mg/100 g and 175.06–203.10 mg/100 g, respectively, whereas the tannin content of the extruded and unextruded composite flours was 8.4–22.89 mg/100 g and 23.67–36.97 mg/100 g, respectively. There was a statistically significant (p < 0.05) difference among the extruded composite flours in terms of phytate and condensed tannin content. Paired t-test has indicated a significant (p < 0.05) difference between extruded and unextruded composite flours for phytate and tannin. Water absorption capacity and bulk density have shown a significant (p < 0.05) difference among extruded and unextruded composite flours. An increase in the proportion of soybean and linseed flour was associated with an increase in phytate, tannin, and water absorption capacity of composite flours. However, bulk density was increased with an increasing proportion of oat in the blend.Conclusion: The findings revealed that extrusion cooking significantly reduced phytate and condensed tannin content and improved the functional properties of the composite complementary food flour. Further investigation is needed on other anti-nutritional factors that are not included in this report.

Bambara nut (Vigna subterrenean) is a cheap source of leguminous protein that can be a good substitute for relatively expensive animal protein to reduce malnutrition. Despite its potentials, it remains underutilized owing in part to long cooking time, presence of antinutritional factors and drudgery in dehulling. In this regard, this study determined effects of fermentation on antinutritional and functional properties of bambara nut flour. Bambara nut was procured from local market in Abeokuta while pure culture of Rhizopus oligosporous was obtained at the Department of Food Science and Engineering, Ladoke Akintola University of Technology. Bambara nut was fermented for 12, 24, 36, 48, 60 and 72h at 32ºC and dried in oven (55ºC/24 h). The antinutritional (tannin, oxalate, phytate, and trypsin inhibitor) and functional properties (water-absorption-capacity, solubility and swelling power) of the composite flour were determined. The data obtained were subjected to descriptive and inferential statistics and significance established at P=.05. Respective range of values for tannin, oxalate, phytate and trypsin inhibitor were 0.08 - 0.32, 0.72 - 1.49, 0.15 - 3.64 and 0.42 - 3.25 mg/g, respectively. Water absorption capacity, solubility and swelling power ranged from 8.67 - 11.04, 52.59 - 53.07, 9.20 - 10.16 and 9.14 9.16%,  respectively. The fermentation process reduced the antinutritional factors and increased the protein content.

The market of composite flour is growing as consumer nowadays choosing a healthy diet as personal preference. The suitability of the composite flour for use as intermediate or finish food ingredients highly depends on its physicochemical properties and its nutritional value. In this study, four types of local fruit crops (particularly their seeds) namely rambutan, cempedak, durian and nangka were dried and ground into powder form. The physicochemical properties such as bulk density, pH, water absorption capacity (WAC), oil absorption capacity (OAC), foam stability (FS), foam capacity (FC) as well as gelatinization properties of these composite flour were studied. Mineral content and heavy metal analytes were also determined. Results for bulk density from the least to the higher amount was 0.54±0.00 g/mL, 0.57±0.00 g/mL, 0.58±0.01 g/mL, 0.66±0.00 g/mL , 0.70±0.00 g/mL and 0.72±0.00 g/mL for rambutan flour, cempedak flour, tapioca flour, nangka flour, wheat flour and durian flour, respectively. Both cempedak flour and nangka flour showed the lowest pH value (5.72±0.01, 5.73±0.00), followed by rambutan flour and durian flour (6.67±0.00, 6.90±0.00) which similar to that tapioca flour and wheat flour (6.65±0.1, 6.08±0.0), respectively. Rambutan flour, cempedak flour and wheat flours showed the highest value in% of foam stability meanwhile these composite flours showed the lowest value in% of foam capacity. Results for water absorption capacity (WAC) and oil absorption capacity (OAC) in a range of 6% to 42% and 8% to 12% respectively, however, durian flour obtained the highest value for WAC while the value for OAC was the lowest. All of the composite flour possesses gelling properties at 13% concentration except for cempedak flour which completely gels at 20% of concentration. Rambutan flour showed the highest mineral analyte particularly in Zinc (107.19±0.17) and Copper (14.22±0.27) followed by nangka flour [Zinc (64.20±0.32) and Copper (10.40±0.12)] and durian flour [Zinc (52.38±0.42) and Copper (7.97±0.05)]. Level of heavy metal toxicity was under risk for all types of composite flour.

<p>Adlay (Coix lacryma-jobi L.) is a potential source of starch but has not been utilized optimally. Native adlay starch has several weaknesses such as functional properties of low swelling volume and solubility, prone to retrogradation, and low stability. Physical modification of ultrasonication and chemical modification by oxidation using ozone can be an alternative to improve the functional properties of adlay starch through the formation of porous starch. The aim of this research was to produce porous adlay starch by ultrasonication and ozonation. The study consisted of several different treatments on hanjeli starch (ozonation starch, ultrasonication of 15 minutes, ultrasonication of 30 minutes, combined ultrasonication of 15 minutes and 30 minutes with ozonation). The results showed the appearance of pores on the surface of the granules of modified adlay starch with the best results being modified combination of ultrasonication 30 minutes and ozonation, which resulted in a decrease in swelling volume from 18.13 ± 3.98 mL/g to 15.71 ± 0.35 mL/g, an increase in solubility from 6.76 ± 0.62% to 9.59 ± 0.44%, and a decrease in water absorption capacity from 1.25 ± 0.02 g/g to 1.13 ± 0.02 g/ g. Modification of adlay starch by ultrasonication, ozonation, and their combination effectively produced porous starch granules, but did not cause the formation of new functional groups in starch.</p>

The functional, sensory and cooking characteristics of noodles from blends of Acha-tigernut composite flour were investigated. The flour blends and noodles produced were analyzed for functional properties and cooking characteristics. The tiger nut flour was substituted into acha flour at 5, 10, 15 and 20% to produce Acha-tigernut composite flour which was used with other ingredients (salt and powdered ginger) to produce acha-tigernut based noodles. The functional properties of the flour, sensory and cooking characteristics of the noodles produced were determined. The water absorption capacity and swelling capacity increased from 210.59 to 215.53 (g/g) and 524.43 to 586.57, respectively with increase in tigernut flour. While oil absorption, solubility and bulk density decreases from 209.80 to 192.72 (g/g), 10.17 to 5.19 and 0.79 to 0.61 (g/ml) respectively. The swelling capacity ranged from 524.43 to 586.57 (%) with an increase in tigernut flour. The final viscosity of the samples was found to range from 2833.00to 2201.00 (m2/s). The peak properties decreased from 2680.67 to 1580.33 (RVU). The pasting temperature increases from 82.47to 87.57°C. The addition of tigernut decreased the trough, breakdown and peak time from 1730.67 to 1205.67, 985.67 to 434.67, and 5.84 to 5.71 RVU, respectively. The average mean scores for colour decreased from 6.95 to -6.30(%) While that of taste, flavor, texture and general acceptability increased from 5.55 to 6.60, 5.95 to 6.85 (%), 5.95 to 6.44 (%) and 6.70 to 6.83 (%), respectively, as the percentage of tigernut increased.

Cookies are ready to eat convenient food for all ages and the consumption is on the increase in Nigeria due to urbanization which has led to increase in wheat importation. In order to reduce the effects of wheat importation on the economy, this study looked into the use of locally grown crops for production of cookies. Cookie samples were produced from blends of wheat flour, germinated finger millet and African yam bean. Different proportions of flour blends were obtained using design experts. The flour mixes were evaluated for the proximate, minerals composition, antinutrients and the functional properties while the sensory properties of the cookies were determined. The proximate composition of the composite flour varied from 12.20-12.54; 8.89-10.62; 1.31-1.65; 1.13-1.39; 1.82-1.48 and 74.33-72.66% for moisture, protein, fat, crude fibre, ash and carbohydrate content of the flour, respectively. The mineral content of the flour ranged from 9.064-9.10, 0.29- 0.32, 0.42-0.45, 0.24-0.28% for calcium, phosphorus, potassium and sodium, respectively. The anti-nutritional properties of the flour ranged from 0.0074 to 0.0098%, 0.1700 to 0.1990%, 0.0905 to 0.1080% and 1.2500 to 1.4900%, for tannin, phytate, oxalate and trysin inhibitor, respectively. The functional properties of the composite flour ranged from 0.66-0.67 g/ml; 25.87- 27.48 g/ml; 6.11-8.12 g/ml; 0.75- 0.83 g/ml; 106.65 to 124; 91.70-99.75 g/100g; for bulk density, water absorption capacity, oil water capacity, foaming capacity and foaming solubility, respectively. The sensory attributes studied were colour, taste, texture and crispness. This study has shown that there was a notable improvement on the nutritional and functional properties of the flour while there was reduction in the ant nutrients.
