This study was aim to evaluate the physical properties of wheat-tiger nut flour mixes and physical, proximate and sensory attribute of pancakes developed from wheat-tiger nut flour mixes. Fresh yellow variety of tiger nut (Cyperus esculentus) tubers and other ingredients used for this research were purchased from the Isara market, Saapade, Ogun State, Nigeria. The tiger nut seed were sorted, soaked and germinated for 48 hrs, dried and processed into flour. Pancakes were prepared after incorporation of 10, 20, and 30% of germinated tiger nut flour. The water absorption capacity and solubility values ranged from 44.66 g/ml – 53.00 g/ml and 3.96-8.06% respectively. The result of the swelling power and bulk density varied from 295.00-337.66% and 497.51 kg/m3 - 555.55 kg/m3. The result of the proximate composition of the pancake showed that the protein, moisture, fat, ash and crude fiber increased significantly (p = 0.05) while the carbohydrate contents decreased significantly with an increase in the germinated tiger nut flour substitution. The protein values ranged from 11.91 – 21.75 with sample D having the highest value of protein at substitution level of 30% germinated tiger nut flour compared to the control sample A. The physical properties of the pancake viz thickness, diameter and spread factor ranged from 2.10-10.00 mm, 111.33-158.66 mm, 111.00-757.14 mm respectively. Sensory data indicated that the pancake produced from germinated tiger nut flour with 30% was acceptable. In conclusion, this study has shown that the use of tiger nut can be considered as a potential ingredient in baking and production of high protein and high fiber products. Nevertheless, it is important to consume snacks with other protein-rich diets to supplement the reduction resulted from substitution.

In this study, carried out at Makurdi Nigeria, peanuts and avocado pulp were processed into flours and blended with refined wheat flour in proportions 100:0:0, 95:5:0, 90:5:5, 85:10:5, 80:10:10 and 75:15:10. The functional properties of the flour blends were determined. Cookies were made using the creaming method from these flour blends with one hundred per cent wheat flour serving as control. The physico-chemical and sensory properties of cookies from wheat/defatted peanut/avocado flour were determined using standard analytical methods. The functional properties of the flour blends increased with increasing substitution of wheat flour with defatted peanut flour and avocado flour. The enriched cookies were found to have higher protein, energy, vitamin and mineral content as compared to refined wheat cookies. The protein content increased from 15% in the control sample to 26.64% in the sample F which is the sample with the highest substitution of wheat flour. Magnesium content increased from 173.37 mg/100 g in the control sample to 221.36 mg/100 g in sample F. There was no significant difference in the dietary fibre content of the enriched cookies as compared to the control. Substitution with peanut flour and avocado flour did not alter the physical properties of the cookies. The sensory scores for all the cookies enriched with defatted peanuts flour and avocado flour were above average 4.5. Sample C, with 5% peanut flour and 5% avocado flour had the best sensory attributes among the supplemented cookies at 5% level of significance and compared favourably with the control cookies. Thus cookies made from wheat, defatted peanut and avocado composite flour at an optimal substitution level of 90;5;5 can be regarded as a suitable balanced meal.

Cassava starch extracted from cassava roots (Manihot esculanta) is a highly used ingredient for most commercial food products and has a high viscosity, water holding capacity, and binding abilities. The objective of this study was to determine the effect of replacing composite flour mixture with cassava starch on the nutritional and physical properties of chicken sausages. A scientific experiment was designed for the sausage formulation to incorporate 50% to 100% with cassava modified and native starch compared to the control sample. These samples were evaluated for sensory and textural properties. Nonparametric data obtained through sensory evaluation were analyzed using the Friedman ranking test. According to the test results, the best sample was analyzed for the nutritional toxicological composition and storage stability. According to the statistical analysis, the sample which was 50% replaced with native cassava starch showed the best sensory profile. The best sample showed average moisture, crude fat, crude protein, total solids, ash, and acid-insoluble ash content of 65.98, 7.19, 8.79, 34.02, 2.36, and 0.32 percent respectively. The starch content of the best-ranked sample was 3.12 and the cyanide content of that sample was 1.54 ppm on a dry basis. According to the microbial analysis results, the sausage sample was coliform negative and zero initial plate count was obtained. Besides, the best-ranked fresh chicken sausage was nutritionally acceptable and could keep for 14 days without adding preservatives.

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.

The study aimed at assessing effects of partial replacement (0–40%) of wheat flour with roasted flaxseed flour (RFSF) on the quality attributes of biscuits. Nutritional, antioxidative, volatile and sensory properties, as well as texture analysis and the contents of macroelements and microelement were studied. Increasing RFSF content in biscuits resulted in a significant increase (p < 0.05) in protein (from 8.35% to 10.77%), fat (from 15.19% to 28.34%) and ash (from 1.23% to 2.60%) while the hardness and spread factor of the biscuits decreased with the increased level of roasted flaxseed flour. Moreover, the addition of 40% RFSF registered a positive influence on the fibre content of the final baked biscuits, increasing its value about 6.7-fold than in the control sample. Total phenolic content, antioxidant activity and biscuits’ aroma volatile profile increased their amounts with RFSF addition. The nutritional, textural and sensorial results of the present study demonstrated that 25% RFSF could be added in the biscuits manufacturing without affecting the biscuits aftertaste, offering promising healthy and nutritious alternative to consumers.
