Article Citation - WoS: 1Citation - Scopus: 1Exploring Sainfoin (Onobrychis Viciifolia) Seed Flour as a Sustainable Plant-Based Food: Germination-Induced Changes in Nutritional Quality, Anti-Nutritional Factors, Phenolic Content, Bioaccessibility, and in Vitro Toxicity(Wiley, 2025) Kaya, Havva Polat; Gungor, Sevde Nur; Tuncel, Nese Yilmaz; Sakarya, Fatma Betul; Andac, Ali Emre; Ozkan, Gulay; Tuncel, Necati BarisBackground and Objectives: Sainfoin is a drought-resistant perennial plant mainly used as animal feed, but its seeds remain underexplored as a food source. This study investigates the effects of germination on the nutritional quality of dehulled sainfoin seeds. Specifically, it examines changes in proximate composition, antinutrients (hydrocyanic acid, tannins, phytates, saponins, and trypsin inhibitors), in vitro starch digestibility, phenolic content, antioxidant capacity, and cytotoxicity. Findings: Germination significantly increased crude protein (up to 45%) and fat (up to 10%) contents. Despite low total starch (similar to 7%), 45-h germination reduced total digestible starch while increasing rapidly digestible starch. Antinutrient levels decreased significantly-tannins by 57%, phytates by 30%, saponins by 40%, and trypsin inhibitors by 29%-with the exception of hydrocyanic acid. Although total phenolics, flavonoids, and antioxidant capacity declined, their bioaccessibility improved. No cytotoxic effects were observed in either raw or germinated seeds. Conclusions: Germination improved the nutritional profile of sainfoin seeds by increasing protein and fat contents, while reducing most antinutrients. Despite a decrease in antioxidant levels, their bioaccessibility was enhanched. The absence of cytotoxic effects further supports the potential application of germinated sainfoin seeds in human nutrition. Significance and Novelty: Although few studies have focused on the green form of sainfoin, which is commonly used as livestock feed, this study reveals that sainfoin seeds offer substantial potential as food, with germination emerging as a simple and effective approach to improving their nutritional properties.Article Citation - WoS: 16Citation - Scopus: 22Phenolic Contents, Antioxidant Activities and Potential Bioaccessibilities of Industrial Pomegranate Nectar Processing Wastes(John Wiley and Sons Inc., 2016) Sürek, Ece; Nilufer Erdil, DilaraAntioxidant potential and bioaccessibility of co-products from industrial pasteurised pomegranate nectar (PN) processing such as peel (PP), press cake (PC) and precipitate after clarification (PAC) in comparison with raw material (arils) and final products (CON and PN) were determined. Total phenolic (TPC), flavonoid (TFC), anthocyanin (TAC), tannin contents (TTC) and antioxidant activity (TAA) were determined besides identifying major phenolics and investigating in vitro bioaccessibility after gastrointestinal (GI) digestion. PP showed the highest values, except for TAC. Phenolics (12.7-43.0%) were found to be more stable than anthocyanins (0.6-2.1%) after in vitro GI digestion. PAC was found to be a better source for anthocyanins than CON and also showed higher phenolic bioaccessibility (28.8%) than PN (19.6%). PC and PAC possessed as much TPC, TFC, TTC and TAA levels as CON, with some exceptions. Therefore, these results indicated that not only PP but also PC and PAC should be valorised as a good source for phenolics and anthocyanins.
