    Abstract:
    The by-products obtained from orange and cucumber industries, such as pomace and peel, are usually discarded after primary processing. In this study, orange pomace and cucumber peel were microwave dried (180 W for 40 min) to prepare powders and incorporated at varying levels (5%-20%) to prepare tricolor pasta. The prepared pasta was evaluated for its nutraceutical, cooking, textural, and sensory characteristics. The viscoelastic behavior of orange pomace (OPP) and cucumber peel (CPP) powder enriched pasta dough was also analyzed. The elastic modulus (G') and viscous modulus (G″) of dough increased with the incorporation of the higher proportion of pomace and peel powder. The total dietary fiber in pasta incorporated with OPP increased from 10.30% to 20.19%, while it was increased to 24.91% upon the incorporation of CPP. These powders also contributed to the natural orange and green color of pasta. The antioxidant activity of OPP pasta increased from 10.64% to 31.9% and 10.64% to 20.29% in CPP (at a 20% level). Total phenolic content, carotenoid content, and chlorophyll content of OPP and CPP enriched pasta were determined, which progressively increased with increased levels of both the powders. The firmness of OPP increased from 0.29 to 1.54 N and 0.29 to 1.87 N in CPP at their highest level (20%) of addition. Therefore, orange pomace and cucumber peel waste from industries can be efficiently used to prepare pasta with improved nutritional characteristics.
