Improving antioxidant and anti-hyperglycemic activity in cereal and apple-based food formulations using bioactive ingredients from apple peel

摘要

Edible ingredients derived from phenolic bioactive enriched fruits such as apple can be integrated into food formulations to improve overall human health-relevant functionalities. High phenolic bioactive enriched apple peels were used as a source of dehydrated edible ingredients for formulating cereal-based muffin and apple puree. Prior to utilizing in food formulations, proximate composition, dietary fiber, mineral composition, and phenolic-linked antioxidant activity of the source material, and apple peel dehydrated (APD) powder were evaluated. Furthermore, chemical composition, phenolic-linked antioxidant, anti-hyperglycemic properties (α-amylase and α-glucosidase enzyme inhibitory activities), and sensory properties of the formulated food, muffin, and apple puree, with and without APD powder integration were determined. Total phenolic content, dietary fiber content, total antioxidant activity, and anti-hyperglycemic properties increased with the incorporation of APD powder, specifically in muffin. These results suggested that the APD powder can be rationally utilized as edible ingredients to improve overall nutritional qualities, especially for type 2 diabetes-linked benefits.
