A study on proximate composition, functional properties and prebiotic capacity of dietary fibers isolated from Apium graveolens var. dulce pomace
Published: July 29, 2026
Abstract
This study investigated the proximate composition, functional properties, and potential health benefits of total dietary fiber and its soluble and insoluble dietary fiber fractions isolated from celery pomace. The result revealed that the insoluble dietary fiber has great hydration properties with a swelling capacity of 30.41± 0.35 mL/g dry basis. The total dietary fiber is useful for reducing sugar blood ability due to its value of glucose adsorption with 2.20 ± 0.02 mg glucose/g dry basis. Notably, the soluble dietary fiber fractions demonstrated significant prebiotic activity, increasing colony-forming units and titrating acid total content by 26.86 and 3.43 times, respectively, after 48 fermentation hours. Apium graveolens var. dulce pomace fiber fractions show potential asfunctional and prebiotic ingredientsfor food products.
