In response, this study investigates the effects of different temperature-controlled techniques on the gelling properties and flavor quality of preserved eggs. The results show that compared with an overall constant temperature and a two-stage temperature-controlled technique, the P-12–18–30 °C three-stage temperature-controlled pickling model produced the best texture properties of the preserved egg white gel, as further verified by LF NMR and SEM analysis. The results of amino acid analysis also show that the taste intensity of free amino acids in the P-12–18–30 °C group was significantly increased, especially for umami amino acids. In addition, the results of the electronic noise show that the volatile components of preserved eggs subjected to different temperature-controlled pickling techniques were similar, mainly consisting of short-chain alkanes; alcohols, aldehydes, ketones, and some aromatic compounds; long-chain alkane aliphatic groups; and inorganic sulfides, and there was no significant difference in the content of each flavor substance. In conclusion, this study offers theoretical basis for temperature-controlled pickling of preserved egg with better gel quality.</p></div>","PeriodicalId":100545,"journal":{"name":"Food Physics","volume":"1 ","pages":"Article 100009"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2950069924000033/pdfft?md5=15ce4df8aaf8a103ec430f2d6a0ca5e8&pid=1-s2.0-S2950069924000033-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140536338","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results showed that ultrasonic-assisted thawing increased the thawing rate and shortened the thawing time by 26.72–64.99 % compared to water immersion thawing, and inhibited the lipid oxidation. Regarding the quality characteristics of frozen pork, the samples thawed by combined tri-frequency sequential ultrasound mode (TSEU) at 20/50/35 kHz exhibited better water retention (lower thawing loss and cooking loss) and physicochemical quality (lowest hardness, highest tenderness, lower TBARS values). Low-field nuclear magnetic resonance results displayed that the mobility and loss of bound and free water in pork tissue reduced effectively after ultrasound treatment at 20/50/35 kHz. The microstructure analysis revealed that the microstructure of pork thawed by 20/50/35 kHz was closest to that of fresh meat, and the distribution of muscle fibers was close and regular. Therefore, TSEU at 20/50/35 kHz was considered to be the most appropriate treatment for pork thawing, which could significantly accelerate the thawing rate and maintaining the meat quality.</p></div>","PeriodicalId":100545,"journal":{"name":"Food Physics","volume":"1 ","pages":"Article 100002"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49721207","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
