Pea peels as a value-added food ingredient for snack crackers and dry soup

Abstract

Abstract 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.
