The food industry produces large quantities of waste, which is available in bulk at zero cost. This study aimed to investigate a new method to maximize the protein intake from pea peels and its further utilization as a value-added food ingredient to produce healthy snack crackers and dry soup. Dehydrated green curd of pea peel (DGCPp) with high protein content (35%) was prepared and incorporated into snack cracker and instant soup powder. Wheat flour was substituted with DGCPp to prepare crackers at three substitution levels (5, 10, and 15%) compared to the cracker control sample (100% wheat flour). Increasing the level of this substitution improved the nutritional value of crackers, with highest protein content was in DGCPp crackers (15%). Crackers also had higher contents of mineral and essential amino acids. The physicochemical and sensorial properties of soup samples were significantly influenced by the addition of DGCPp. Higher rehydration value and mineral content (Ca, Mg, Fe, and Zn) were observed in DGCPp soup samples compared to the control sample. Soup samples of all proportions were more acceptable by all the panelists compared with the control sample. With these findings, it can be concluded that DGCPp can be utilized in a variety of food products (such as crackers and soups) with higher nutritive values.
食品工业会产生大量的废弃物,这些废弃物可以大量免费获得。本研究旨在探索一种从豌豆皮中最大限度地提取蛋白质的新方法,并将其进一步用作增值食品成分,以生产健康的小吃饼干和干汤。制备了高蛋白含量(35%)的脱水豌豆皮绿饼(DGCPp),并将其添加到小吃饼干和速溶汤粉中。与饼干对照样品(100%小麦粉)相比,用 DGCPp 替代三种替代水平(5%、10%和 15%)的小麦粉来制备饼干。随着替代水平的提高,饼干的营养价值得到了提高,DGCPp 饼干的蛋白质含量最高(15%)。饼干还含有更高含量的矿物质和必需氨基酸。DGCPp 的添加显著影响了汤品样本的物理化学和感官特性。与对照样品相比,DGCPp 汤品样本的复水值和矿物质含量(Ca、Mg、Fe 和 Zn)更高。与对照样品相比,所有比例的汤样都更受所有品尝者的欢迎。根据这些发现,可以得出结论,DGCPp 可以用于各种食品(如饼干和汤),以提高营养价值。
