Abstract Objectives To improve the nutritional values of corn flakes enriched with edible mushrooms Methods Corn was processed into grit flour by cleaning, cooking and blending while oyster mushrooms was cultivated using substrate such as palm bunches, cocoa waste and wheat bran which was then roasted, dried and milled to produce mushrooms flour. A blend of corn grit and mushrooms was prepared in various proportions for the production of flakes using the extrusion process, with blending ratios of corn grit: mushroom as follows: MDX (95:5); DMX (90:10); XYZ (85:15); UPX (75:25); and control 100% corn grit. The samples were produced at the same temperature and speed. The corn grit and mushroom blends were subjected to functional and sensory evaluation. Proximate analysis was carried out on the flakes. Results Result of proximate analysis showed that protein, fat and fiber contents increased significantly in some samples with increased mushroom inclusion while carbohydrate decreased with increase in mushroom inclusion. For protein, values ranged from 0.98% in control sample to 5.55% in sample UPX (75:25); fat content ranged from 1.11% in control sample to 5.27% in sample UPX (75:25). Carbohydrate content ranged from 83.59% in control samples to 72.49% in sample UPX. There was also an increase in ash content with values ranging from 0.33% in control sample to 1.79% in sample UPX. Fiber increased from 6.17% in control sample to 8.26% in sample UPX. However overall acceptability evaluation showed that sample DMX (90:10) had the best in terms of acceptability. Functional properties for water absorption capacity, bulk density and swelling index indicate values ranging from 5.77 in control sample and 4.42 in sample UPX. Bulk density had values of 0.69 to 0.8; for swelling index it ranged from 4.53 to 4.72 for the various tests respectively Conclusions Increased mushroom inclusions decreased dough strength in flakes produced. However, edible mushrooms have shown tremendous potentials for complimenting the diet of toddlers at appropriate inclusion ratios for optimal growth Funding Sources Self funding.

The blends were evaluated for functional properties, total carotene, vitamins (B2 and B6) and sensory properties of the breakfast strips with a commercial breakfast food (Flakes) as control (sample H) . For the functional properties, the water absorption capacity decreased while the oil absorption increased with an increase in substitution levels of the soybean flour. The bulk density, solubility, swelling power and swelling volume were higher in sample A. The least gelation capacity maintained a constant rate of 4% across the blends. The moisture content of the strips ranged from 7.25-9.40%. The Ash contents were below 3% for all the blends. The protein contents increased with an increase in substitution with soybean flour while sample A - breakfast strips from 100% orange-fleshed sweet potato flour showed the highest value for fats (5.62%). The fibre content ranged from 0.69 to 5.14% and carbohydrate content reduced with an increased substitution with soybean flour (72.25-78.70%). The energy value ranged from 351.90-384.80 Kcal/100 g which was within the limit recommended for breakfast foods. Total carotene content increased with increased substitution with orange-fleshed sweet potato (15.18-33.56 mg/kg) which is significantly higher than the control at 0.75 mg/kg. The result of the sensory evaluation showed that the overall acceptability of the samples produced compared favourably with the control. Sample A and B showed a vitamin B2 of 4.70 and 4.00 mg/kg, respectively. However, the values decreased with increase in the addition of soybean while vitamin B6 increased with increase in soybean.

Background Extensive milling processes have deprived wheat flour from essential nutrients. The objective of the current study was to assess the nutritive quality of commercial wheat flour (soft flour (SF)) through analyses of proximate composition and functional properties as well as quantification of benzoyl peroxide (BPO; added as bleaching agent in the SF) by comparing the results with whole wheat flour (WF; never received any additives). Methods The samples included commercial SF purchased from the local supplier of different flour mills (who use BPO as additive) and a control sample without additives was prepared by grinding the seeds harvested from wheat (Triticum aestivum L.; Inqulab 91) crop grown in the experimental field of University of Agriculture, Faisalabad, under optimized field conditions without any fertilizers and insecticides. Functional properties (including bulk density, water absorption capacity, oil absorption capacity, emulsifying activity, foaming capacity, least gelatinization concentration and gelatinization temperature) and proximate composition (including moisture content, ash contents, crude protein, gluten and starch contents) were determined and compared for all the samples. Benzoyl peroxide (BPO) and Benzoic Acid (BA) quantification was performed through High Performance Liquid Chromatography. Finally dietary intake was estimated for BPO and BA. Results Results showed that SF had lesser fiber, protein and ash contents, whereas, higher damaged starch, fat, gluten and bulk density. A parallel experiment under selected conditions (temperature, time and solute concentration) showed dissociation of BPO into BA soon after the exposure. Observed BA range (13.77 mg/g after 16 h) in SF and exposure level assessment (44.3 ± 1.36 mg/kg/BW) showed higher intake of BA on the consumption of SF. The results revealed the superiority of WF over SF in nutritive qualities as well as free of toxicants such as BA.

The feasibility of partially replacing wheat flour with coconut flour in baked products was investigated. Matured coconut (Cocos nucifera) endocarp was grated for the extraction of milk, dried, milled,and pulverized. Five blends of composite flour were prepared by combining wheat flour with 10% to 50% of partially defatted coconut flour,respectively. The 100% wheat flour served as control. The samples were analysed for proximate, mineral, functional,and pasting properties using standard procedures. The proximate analysis indicated 5.52 % moisture, 23.6% protein, 11.14% fibre, 5.4% fat, 5.21% ash,and 49.1% carbohydrate for coconut flour. The ranges of the proximate composition forthe flour blends were:moisture (4.79-5.55%), protein (14.9 -19.1%), fibre (0.44 -5.12%), fat (2.9 -5.3%), ash (0.68-2.13%), carbohydrate (62.7-76.2%),and energy (315.26-335.28 kCal). The values for moisture, protein, fat, fibre,and ash increased with the increasing levels of coconut substitution,except for carbohydrate and energy contents. There were significant differences (p≤0.05) in calcium, magnesium, potassium, phosphorus, iron,and zinc concentrations of the samples. The range of values obtained for these parameters was1.32-2.59 mg/kg, 2.60-3.83 mg/kg, 12.10-16.89 mg/kg, 12.40-18.50 mg/kg,0.50-1.22 mg/kg and 0.30-1.23 mg/kg, respectively. The ranges of functional properties were:loosed bulk density (0.28-0.49 g/mL),packed bulk density (0.44-0.75 g/mL), pH (5.77-6.57), swelling capacity (3.89-6.56%), water absorption capacity (0.89-3.97 ml/g),oil absorption capacity (1.26-3.20 ml/g),and gelation (12.0-18.0%). The pasting characteristics showed significant differences betweenthe100% wheat flour and coconut substituted samples. The results revealed modifications in nutritional, functional,and pasting properties in blends containing fractions of partially defatted coconut flour,which suggeststheir application in diverse food products.

This study aims to produce corn nixtamalized tortillas enriched with faba-bean (25%, 50%, 75% w/w) and white-bean (25%, 50%, 75% w/w) flours. Faba-bean and white-bean are Andean crops (AC) rich in protein, carbohydrates, fiber, minerals, vitamins, and gluten-free. Tortillas were characterized in terms of proximal, physicochemical, sensorial, microbiological, and texture properties. Proximal composition shows that corn flour has 14.5 % less protein, 0.83 % less ash, and 1.39 % fatter than faba-bean flour, while in white-bean flour, the fiber content is three times higher. Moisture content was less than 14 %, which guarantees the control shelf-life; gluten content was approximately 5 ppm. Granulometry properties showed that flours have coarser than finesse particles, water absorption capacity showed a range of 60 to 80 g of water for 100 g of flour. In nixtamalized tortillas, high protein content was observed in samples with 25 % of corn and 75 % of two different Andean crops. Enriched tortillas showed lower lipid content, higher dietary fiber, and higher ash content than the control sample. The sensorial analysis showed that the best formulation based on overall acceptability was 25% (w/w) of corn flour and 75% of white-bean flour. The oil content showed that the samples absorbed about 8% of oil during the toasted. The hardness parameter showed that the sample CPB2575: Corn flour (25%) + White-bean flour (75%); was harder than the control. The microbiological evaluation established that the tortillas comply with the normative what indicates the absence of harmful microorganisms to public health. Color parameters showed that samples tend to lightness with a tendency to reddish color in enriched tortillas while in control are greenish. Andean crop flours are one alternative to increase the nutritional value of corn tortillas with acceptable sensorial characteristics.

The most interesting component of wheat is the wheat germ that is recognized as a secondary product in the industry of wheat milling; it has fascinating nutritional values that cannot be ignored. However, it has slender usage due to its significant chance of rancidity and the negative effect it causes the dough quality. Investigation in this study showed that how wheat germ affects the rheological quality of dough and the influences on the final product by its addition to bread, also to find out the best and most amount of wheat germ addition with the best bread quality that is unrecognizable by customers. For this intention, divergent quantities of the mille draw germ of wheat (5%, 10%, 15%, and 20%) were added to the flour used for making bread dough. Afterward, the dough’s rheological characteristics and the endmost quality characteristics of the bread were analyzed and compared to the control sample from both the Sensory evaluation and physical evaluation sentiments. Wheat germ insertion to dough flour caused an increase browning of the dough but decreased dough firmness, stretch-ability, and dough strength. The more the amount of the additional wheat germ to the wheat dough, the more the changes appeared, including decreasing extensibility and strength in addition to taste the difference. The bread made from dough with the highest amount of inserted wheat germ dispensed the smaller volume, less elasticity, and cohesiveness, while more firm and darker in color of both crust and crumb of the product. All bread acquired allowable outcomes in the sensory examination, yet inserting of wheat germ with a rate of (20% to flour) decreased appearance, texture, and overall acceptability outcomes of bread. Consequently, the addition of the germ worsens the rheology attribution of dough, lessen gelatinization temperature and qualification of bread, so it has to be added in a particular amount to keep both nutritional value and the quality of the bread as high as possible.

Background: Rice bran, a byproduct of rice milling is a rich source of fiber, proteins, fats and micronutrients. There is an increasing demand for functional foods that can provide a variety of nutrients besides providing bioactives rendering therapeutic value thereby reducing the risk of chronic diseases. Methods: The study was carried out to evaluate the physicochemical and in vitro antioxidative potential of stabilized rice bran powder [full-fat rice bran (FFRB) and defatted rice bran (DFRB)] in baked products. Three variants of each product viz. rusks and twisted sticks were prepared by incorporating FFRB and DFRB at 5%, 10% and 15% level along with the standard (control) without the addition of rice bran powder. Results: The results indicated that DFRB showed higher antioxidative potential and improved water absorption capacity (WAC), oil absorption capacity (OAC) than FFRB. Proximate analysis revealed that the protein and ash content of the baked products improved significantly (p ≤ 0.05) with an increased level of incorporation of FFRB and DFRB as compared to control. The DPPH activity of DFRB (78.7 ± 0.46) was significantly higher than FFRB (35.5 ± 2.89). Sensory appraisal of the rusk revealed that variant I and II with 5% and 10% level of incorporation were more acceptable as compared to control. The sensory appraisal of twisted sticks revealed that all the three variants were equally acceptable as the control sample. Conclusion: The incorporation of full fat and defatted rice bran powders to baked products enhanced their nutritional profile and physicochemical characteristics without affecting the organoleptic properties.

Protein-energy malnutrition among Nigerian children is a major health challenge. This nutrition problem is attributed to the inappropriate complementary feeding practices, low nutritional quality of traditional complementary foods and high cost of quality protein-based complementary foods. Therefore, the aim of this study was to formulate complementary foods from popcorn flour and cashew nut. A quantity (500g) of each popcorn and cashew nut seeds (500g) was processed into fermented, germinated and roasted flours. The blends (40% popcorn, 60% cashew nut) were biochemically evaluated for proximate, minerals and amino acids profile. The microbiological properties and sensory attributes were determined using standard methods. For Protein, the results were 22.48% for germinated popcorn-cashew nut (GPC),20.76% for roasted popcorn-cashew nut (RPC) and 21.82% for fermented popcorn-cashew nut (FPC); values for ogi and Nutrend were 12.60% and 16.27% respectively. With respect to energy value, FPC, GPC, RPC, ogi and Nutrend had 533.85, 516.65, 530.49, 389.88 and 397.68 kcal, respectively. The percentages of total essential amino acids in the composition of the blends were36.9%, 40.7% and 38.9%for FPC, GPC and RPC, respectively; non-essential amino acids contents were 63.1%, 59.3% and 61.1% for FPC, GPC and RPC, respectively. The mineral content, that is, potassium, zinc and magnesium, of formulated samples were higher than those obtained for ogi and Nutrend. The antinutrient composition of FPC was lower than that of GPC and RPC. For the functional properties, water absorption capacity was between 1.83 – 1.93 g/ml, least gelation concentration 12.67 – 14.00 g/ml, swelling capacity 0.40 – 0.74 g/ml, loose bulk density 0.43 – 0.49 g/ml and packed bulk density 0.69 – 0.83 g/ml for the formulated samples. The overall acceptability of FPC was rated higher than GPC, RPC and ogi, but lower than Nutrend. For the microbial status, bacteria count was between 1.00–39.00 x 104 cfu/g, mould1.00–4.00 x 104 cfu/g and yeast 1.00–4.33 x 105 cfu/g. The study concluded that the FPC sample was better than ogi in terms of protein and mineral compositions and comparable in overall acceptance to Nutrend. Therefore, the FPC may be used as a complementary food.

This study investigated the functional and pasting properties of wheat and tigernut pomace flour blends, as well as the sensory attributes of the meat pie obtained from the composite flour. Tigernut pomace flour was substituted for wheat flour in the amount of 2 –10%. Unsubstituted wheat flour served as the control. The composite blends were analysed for functional and pasting properties. The sensory attributes of the meat pie obtained from the composite flour were also determined. Bulk density, water absorption capacity, swelling power, and the solubility index of the blends ranged from 0.70 -0.75 g/mL, 0.62 -0.96%, 4.06 -4.47 g/g, and 2.45 -13.7% respectively. Peak, trough, breakdown, final, and setback viscosities, peak time, and pasting temperature ranged from 113.6 -135.9 RVU, 76.7 -90.2 RVU, 36.0 -45.8 RVU, 170 -183.7 RVU, 91.0 -93.6 RVU, 5.07 -6.03 min, and 88.4 -90.0 RVU respectively. In terms of appearance, the meat pie samples prepared from tigernut-substituted flour blends did not show significant difference (p &lt; 0.05) from the control sample. The control sample had the highest overall acceptability, although samples from the composite blends were also found to be acceptable. Hence, tigernut pomace flour could be substituted for wheat at the amount of 10% to produce an acceptable meat pie.
