The fruit of <i>Prunus yedoensis</i> is abundant in anthocyanins, which possess strong antioxidant activity and effectively neutralize free radicals. In the present investigation, to optimize the extraction parameters for anthocyanins obtained from the fruit of <i>P. yedoensis</i>, response surface methodology was employed. Extraction time, ethanol concentration, and extraction temperature were carefully examined as key parameters to determine their influence on the yield and efficiency of anthocyanin extraction. Ultrasonic-assisted extraction extracted in this way showed higher antioxidant activity than conventional extract. In addition, the anti-inflammatory activity of UAE was confirmed, and changes in nitric oxide, inducible nitric oxide synthase, tumor necrosis factor alpha, and Interleukin-1 beta were observed. In conclusion, the extraction method of anthocyanins from <i>P. yedoensis</i> was optimized, and UAE extracted in this way had high antioxidant and anti-inflammatory activities.</p></div>","PeriodicalId":566,"journal":{"name":"Food Science and Biotechnology","volume":"34 9","pages":"2039 - 2049"},"PeriodicalIF":2.4,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143784285","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The oil-in-water (O/W) nanoemulsions were prepared with tea tree essential oil (TTO) and its main components, 1,8-cineole (CN) and terpinen-4-oil (T4O) as core materials, and with tea saponin as surfactant. The preservation properties of the pad containing nanoemulsion slow-release system on <i>Lateolabrax japonicus</i> fillets were measured. The results showed that the nanoemulsion had good stability and can delay the release of essential oil, and the cumulative release percentage of TTO was as high as 81 % at 72 h. The establishment of nanoemulsions slow-release system effectively improved the preservation properties of the pad, and TTO nanoemulsion pad (TTO-NE-P) had the optimal preservation properties due to the synergistic effect of preservative ingredients and the sustained release system of the nanoemulsion. This study can provide technical support for the combined application of biological preservative agent and aquatic product pads.</p>","PeriodicalId":566,"journal":{"name":"Food Science and Biotechnology","volume":"34 9","pages":"1921 - 1933"},"PeriodicalIF":2.4,"publicationDate":"2025-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143784235","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
