Cassava flour has a high potential to contribute as a raw material in the food industry. This study was aimed at characterizing flours from Sri Lankan cassava varieties with a view to explore the potential in food applications. Flours prepared from five cassava varieties, namely, , MU51, , , and , were analyzed for proximate composition and physicochemical, functional, and antioxidant properties using standard methods. Flours from tested cassava varieties contained <1% crude fat and <2% crude protein. Flour from MU51 contained the highest amount of HCN (48.05 mg/kg) while flour from contained the lowest (4.85 mg/kg). Total starch and amylose contents of flours were significantly lower ( < 0.05) than those of commercial wheat flour. Flour from contained approximately similar amylopectin content as commercial wheat flour. Water absorption capacity, oil absorption capacity, water solubility index, swelling power, emulsion activity, and emulsion stability of flours from five cassava varieties were significantly higher ( < 0.05) than those of commercial wheat flour. was identified as the richest source of phenolic compounds (4.44 mmol GAE/100 g dry weight) among the five varieties. Results showed the promising application potential of flours from these five cassava varieties in different food applications such as weaning foods, bakery foods, and edible films.
木薯粉作为食品工业的原料具有很大潜力。本研究旨在对斯里兰卡木薯品种的面粉进行特性分析,以探索其在食品应用中的潜力。使用标准方法对由五个木薯品种(即MU51、 、 、 和 )制备的面粉进行了近似成分、物理化学、功能和抗氧化特性分析。受试木薯品种的面粉中粗脂肪含量<1%,粗蛋白含量<2%。MU51面粉中的氢氰酸含量最高(48.05mg/kg),而 面粉中的含量最低(4.85mg/kg)。面粉的总淀粉和直链淀粉含量显著低于市售小麦粉(P<0.05)。 面粉的支链淀粉含量与市售小麦粉大致相似。五个木薯品种面粉的吸水能力、吸油能力、水溶性指数、膨胀力、乳化活性和乳化稳定性均显著高于市售小麦粉(P<0.05)。在这五个品种中, 被确定为酚类化合物含量最丰富的来源(4.44mmol GAE/100g干重)。结果表明,这五个木薯品种的面粉在断奶食品、烘焙食品和可食用薄膜等不同食品应用中具有良好的应用潜力。
