Chemical Composition and Organoleptic Properties of Bread Produced From Composite Flower Mix of Triticum aestivum and Manihot esculenta Crantz (P04-023-19)

Abstract

Abstract Objectives This work evaluated the chemical composition and organoleptic properties of bread produced from composite flour of wheat (Triticum aestivum) (W) and yellow cassava (Manihot esculenta Crantz) (Yc). Methods Raw yellow cassava from Imo State Polytechnic farm was processed into flour using the method of Singh (2008) while already processed plain wheat flour (Golden Penny brand) and other ingredients were purchased from relief Market Owerri. Standard recipe was used in making the bread in different ratios. Standard methods were used to assay the chemical compositions while organoleptic attributes were determined using a 9-point hedonic scale on the bread produced from composite mix of wheat (W) and yellow cassava (Yc) flours at varied ratios. The chemical components evaluated were moisture, ash, fat, crude fibre, protein, carbohydrate and pro-vitamin A, while the organoleptic properties assayed were crust colour, flavor, taste, crumb texture and overall acceptability. The W: Yc flours mix ratios were 70%: 30%, 80%: 20%, 90%: 10% and 100% wheat respectively as the control, while data collected were analyzed using one way ANOVA. Results The results (Table 1) revealed that carbohydrate value ranged from 61.83% to 63.27%, protein 2.83% to 3.92%, fat 14.86% to 17.86% while crude fibre was 1.01% to 1.99%. Protein value was highest (3.92%) in sample D (100%) while sample B (80%W: 20% Yc) had the least fat content (14.86%). Crude fibre content differed significantly (P˂0.05) among the samples. The provitamin A values (Table 1) increased with increased levels of yellow cassava flour with highest value (0.23%) found in sample A (70%W: 30% Yc). Sensory properties were significantly different (P < 0.05) on all attributes and overall acceptability, while sensory score for crust colour of the bread samples varied insignificantly (P > 0.05) (Table 2). Generally, sample C (90%W: 10% Yc) having 8.10 score for overall acceptability was most preferred (Table 2). Conclusions The results showed that bread produced from wheat and yellow cassava composite flour mix had improved nutritional and organoleptic properties. Funding Sources Self funded by authors.
