Abstract

This study assessed the pigeon pea flour of different treatments; native pigeon pea flour (NPGF), germinated (GPGF), and solid-state fermented (FPGF) at 0, 24, and 48 h The NPGF served as control. The flour samples were analyzed for proximate composition, functional, pasting, rheological properties, mineral content, colour profile, physicochemical attributes, and phytochemical properties. Additionally, sensory evaluation was conducted on the cookies made from these flours. The NPGF sample had the highest moisture and fat content. Pigeon pea flour samples showed a decrease in water absorption capacity, oil absorption capacity, and foaming capacity as fermentation duration increased. The mineral element characteristics could serve as an ingredient for infant food formulation. The control sample (NPGF) had a higher pH value and amylose content than the germinated and fermented samples, and the fermented samples had higher amylopectin content than other flour samples. The GPGF sample shows higher values of total phenolic and total flavonoid content. The sensory characteristics of the cookies varied significantly (p < 0.05) and FPGF-cookies are the most preferred. Pigeon pea flour is deemed suitable for complementary foods such as cookies. Therefore, germinated and fermented pigeon pea flours possess enhanced the nutritional properties, making them valuable ingredients for various food applications.
发芽和固态发酵对鸽子豆粉的化学、功能和营养成分以及饼干感官特性的影响
本研究对不同处理的鸽子豆粉进行了评估:原生鸽子豆粉(NPGF)、发芽鸽子豆粉(GPGF)和固态发酵鸽子豆粉(FPGF)在 0、24 和 48 小时内的状态。对面粉样品进行了近似成分、功能性、糊化性、流变性、矿物质含量、色谱、理化特性和植物化学特性分析。此外,还对这些面粉制成的饼干进行了感官评估。NPGF 样品的水分和脂肪含量最高。豌豆粉样品的吸水能力、吸油能力和发泡能力随着发酵时间的延长而下降。矿物质元素的特性可作为婴儿食品配方的原料。对照样品(NPGF)的 pH 值和直链淀粉含量高于发芽样品和发酵样品,发酵样品的直链淀粉含量高于其他面粉样品。GPGF 样品的总酚类物质和总黄酮类物质含量较高。饼干的感官特征差异显著(p <0.05),FPGF 饼干最受欢迎。豌豆粉被认为适用于饼干等辅助食品。因此,发芽和发酵的豌豆粉具有更好的营养特性,使其成为各种食品应用的重要配料。
