Gluten intolerance, as well as the scarcity of wheat flour in some parts of the world, has prompted the development of gluten-free bread. Gluten-free bread, on the other hand, results in a low specific volume and to remedy this, the use of hydrocolloids and bases has proved to be very successful. The current study aims to determine the optimal proportions of Triumffeta pentendra gum extract and bicarbonate in the breadmaking of a composite flour based on sour cassava starch, peanut flour, and cowpea flour. A Box Benkhen design was used to achieved this, with the variables being the amount of gum extract, the amount of bicarbonate, and the amount of water. The specific volume and texture properties were evaluated as responses. The specific volume was calculated using standard methods, and the textural properties were determined using a texture analyzer. It appears that the incorporation of gums extract, bicarbonate, and water significantly increased the specific volume. The incorporation rate of gum extract significantly increases the hardness, consistency, and masticability which decreases with the incorporation rate of bicarbonate and water. Cohesion and elasticity, on the other hand, increased with the incorporation rate of bicarbonate and water but decreased with the incorporation of gum extract. The optimal gum extract, bicarbonate, and water proportions are 0.28 g, 1.99 g, and 112.5 ml, respectively. As a result, the specific volume is 1.51cm3/g, the hardness is 38.51(N), the cohesion is 0.88, the consistency is 32.86(N), the elasticity is 5.57(1/L), and the masticability is 162.35(mj). According to this findings, gum extracts and sodium bicarbonate can be used to improve the quality of gluten-free bread made with sour cassava starch, peanut and cowpea flour. |
