o:8274 Valorization of Pea Pod waste and seeds for the development of novel food products en The Pisum sativum L. (green pea) is one of the most widely consumed legumes, or vegetable crops, known for fresh eating, processing, or livestock feed. Besides the edible part of the pea, 35%-40% consists of solid waste (pods), an abundant by-product with health-promoting properties. Although pea pods are often thrown away, this waste contains many bioactive compounds (polyphenols and natural pigments). Pea powder can serve as an encapsulation carrier, efficiently using both pea pods and seeds. This study aimed to optimize ultrasound-assisted extraction (UAE) to increase the yield of bioactives from pea pods and to encapsulate the extract, maximizing the value of both pea components. Extraction parameters were varied, including time (15 min, 30 min, 1 h), ethanol concentration (30%, 50%, 70%), and the solvent-to-sample ratio (1:10, 1:20, 1:50), using Design Expert software. The best pea pod extract (58.51% ethanol, extraction time of 45 min, and a solvent-to-sample ratio of 1:48) was concentrated and encapsulated in three forms: pure pea pod extract (1); extract combined with freeze-dried pea powder (2); and combined with whey protein (3), a common protein carrier. Total polyphenolics (TPC) and natural pigments (chlorophyll a, chlorophyll b, and carotenoids) were analyzed in each sample to assess how different carriers affected compound retention. UAE efficiently extracts high levels of bioactives from pea pods, enabling uses across various industries. All encapsulates had high levels of bioactives, although adding freeze-dried pea powder significantly increased chlorophyll a and b to 1758.40 μg/g and 2539.86 μg/g. Using pea powder as an innovative carrier for stabilizing bioactives from pea waste highlights the potential of both as nutraceuticals and functional foods. Both peas and pea pods can be used as key nutrients to support healthy diets, valorize this by-product as an alternative food, and promote sustainable agricultural waste management. pea pod waste; seed, innovative carrier; encapsulation; ultrasound-assisted extraction 1552100 978-86-80383-18-7 91552100 175854345 2025-10-07T12:59:38.832Z 44 no 46 Nada Ćujić Nikolić Institute for Medicinal Plant Research ''Dr. Josif Pančić'' Belgrade 0000-0002-6736-3637 46 Zorana Mutavski Institute for Medicinal Plant Research ''Dr. Josif Pančić'' Belgrade 0000-0002-6998-0292 46 Jelena Mudrić Institute for Medicinal Plant Research ''Dr. Josif Pančić'' Belgrade 0000-0002-6695-2907 46 Ana Matin University of Zagreb, Faculty of Agriculture, Zagreb, Croatia 46 Milica Radan Institute for Medicinal Plant Research ''Dr. Josif Pančić'' Belgrade 0000-0002-6727-7624 46 Dubravka Bigović Institute for Medicinal Plant Research ''Dr. Josif Pančić'' Belgrade 0000-0003-1999-2743 46 Katarina Šavikin Institute for Medicinal Plant Research ''Dr. Josif Pančić'' Belgrade 0000-0002-2086-9593 application/pdf 1109386 https://unilib.phaidrabg.rs/o:8274 no yes 1 70 92000004 71A10 BOOK OF ABSTRACTS Crop Science and Technology: Shaping the Future of Agriculture 113 113 Maize Research Institute Zemun Polje 2025
