During the industrial production of pomegranate juice, peel is generated as a by-product. The aim of this work was to valuate this by-product through the green extraction of soluble antioxidants while recovering insoluble fiber. Pomegranate by-product once dried and ground was subjected to a water extraction process (65 ℃ for 30 min), obtaining two fractions: soluble and insoluble ones. The insoluble fraction had a high fiber content (52,28 ± 2,99 g/100g) while the soluble fraction had a high total polyphenol content (1049,98 ± 3,98 mg gallic acid/100g) and an antioxidant capacity against ABTS radicals of 1486,57 ± 0,05 μmol Trolox/g. Using the soluble fraction, a jelly and a beverage were formulated, while cookies and muffins were formulated with the insoluble fraction. All products were formulated without sugar, and cookies and muffins also complying with the claim "source of fiber". Acceptability was evaluated by consumers (n = 100), being cookies and muffins the most accepted (7,0 and 6,3, respectively). Pomegranate by-product was revalued in a sustainable and low cost way, obtaining new functional ingredients, so representing an opportunity for industry.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
