Wheat is a staple food in many countries globally, but it alone cannot meet the dietary demands of the growing population. To address this, there is an increasingly critical need to integrate alternative cereals into diets, enhancing nutritional diversity and reducing reliance on imports. In present study, various composite blends of wheat and maize were developed by taking different proportions of maize flour (10, 20, 30 and 40%) into the wheat flour and analyzed for proximate composition, phytates, minerals and pasting properties. By using these blends, cookies were made and tested for their physical and sensory evaluation. The crude fat, fiber and ash contents were increased significantly as the amount of maize into composite blends increased but insignificant for moisture, protein and NFE contents while reduction in the phytates was observed. The mineral analysis of various flours showed an increase in the calcium, magnesium, potassium and sodium while decrease in zinc contents. The pasting behaviour of wheat maize composite blends showed a significant decrease in their viscosities as the quantity of maize flour increased. The physical/textural parameters revealed a reduction in diameter and thickness whereas increase in hardness as the amount of maize supplementation increased which had diminishing affect at higher concentrations. It was observed that addition of maize flour into the wheat flour in the development of cookies at higher concentration negatively affected the sensorial attributes.
小麦是全球许多国家的主食,但仅靠它无法满足不断增长的人口的饮食需求。为了解决这一问题,将替代谷物纳入饮食变得愈发迫切,这有助于提高营养多样性并减少对进口的依赖。在本研究中,通过向小麦粉中加入不同比例(10%、20%、30%和40%)的玉米粉,制备了各种小麦与玉米的复合混合物,并对其进行了近似成分、植酸盐、矿物质和糊化特性分析。利用这些混合物制作了饼干,并对其进行了物理和感官评价。随着复合混合物中玉米含量的增加,粗脂肪、纤维和灰分含量显著增加,而水分、蛋白质和无氮浸出物含量变化不显著,同时观察到植酸盐含量降低。对各种面粉的矿物质分析表明,钙、镁、钾和钠含量增加,而锌含量降低。小麦 - 玉米复合混合物的糊化行为表明,随着玉米粉用量的增加,其粘度显著降低。物理/质地参数显示,随着玉米添加量的增加,饼干的直径和厚度减小,硬度增加,而在较高浓度下这种影响逐渐减弱。研究发现,在制作饼干时,较高浓度地向小麦粉中添加玉米粉会对感官特性产生负面影响。
