However, its gel-forming ability is low compared to the cold-water fish surimi. It has been reported that adding polyphenols could improve the gel strength of surimi. Onion extracts containing abundant polyphenols can be a promising option that can modify the characteristics of the protein gels. Furthermore, oxidized polyphenols have a higher capacity to interact with proteins by cross-linking and strengthening surimi gel. Also, the addition of onion extracts is expected to increase the antioxidant capacity of the surimi gels and prolong shelf life. Therefore, this study aims to improve pangasius surimi gel strength and antioxidant capacity by incorporating onion extracts (OE) and oxidized onion extracts (OEox).","PeriodicalId":19722,"journal":{"name":"Nippon Suisan Gakkaishi","volume":"71 0","pages":"420-420"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.jstage.jst.go.jp/article/aamjsfst/71/0/71_420/_pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147897686","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
