It has been extensively reported that sonication is capable of improving food flavour. However, the effect of sonication on the flavour of enzymatically hydrolysed beef liquid (EHBL) was scarcely reported. Herein, we investigated the effect of sonication on the flavour of EHBL using quantitative descriptive analysis (QDA), physicochemical analysis and SPME-GC-olfactometry\/MS. QDA showed that sonication had a significant effect on taste improvement and off-odour removal of EHBL. Compared with the control, sonication (40 kHz, 80 W\/L) increased the contents of total nitrogen, formaldehyde nitrogen, total sugars, reducing sugars, free amino acids (FAAs) and hydrolysis degree of EHBL by 19.25%, 19.80%, 11.83%, 9.52%, 14.37% and 20.45%. Notably, sonication markedly enhanced the contents of sweet FAAs, umami FAAs and bitter FAAs of EHBL by 19.66%, 14.04% and 9.18%, respectively, which contributed to the taste improvement of EHBL. SPME-GC-olfactometry\/MS analysis showed that aldehydes and alcohols were the main contributors to aroma compounds of EHBL, and sonication significantly increased the contents of key aroma compounds and alcohols (115.88%) in EHBL. Notably, sonication decreased the contents of fishy odorants, hexanoic acid and nonanal markedly by 35.29% and 26.03%, which was responsible for the aroma improvement of EHBL. Therefore, sonication could become a new potential tool to improve the flavour of EHBL.<\/jats:p>","DOI":"10.3390\/foods12244460","type":"journal-article","created":{"date-parts":[[2023,12,13]],"date-time":"2023-12-13T04:14:42Z","timestamp":1702440882000},"page":"4460","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Improving the Flavour of Enzymatically Hydrolysed Beef Liquid by Sonication"],"prefix":"10.3390","volume":"12","author":[{"given":"Chao","family":"Ye","sequence":"first","affiliation":[{"name":"School of Food and Biological Engineering, Jiangsu University, Zhenjiang 212013, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhankai","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Food and Biological Engineering, Jiangsu University, Zhenjiang 212013, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhi-Hong","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Food and Biological Engineering, Jiangsu University, Zhenjiang 212013, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0904-0522","authenticated-orcid":false,"given":"Ronghai","family":"He","sequence":"additional","affiliation":[{"name":"School of Food and Biological Engineering, Jiangsu University, Zhenjiang 212013, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xue","family":"Zhao","sequence":"additional","affiliation":[{"name":"School of Food and Biological Engineering, Jiangsu University, Zhenjiang 212013, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8274-1133","authenticated-orcid":false,"given":"Xianli","family":"Gao","sequence":"additional","affiliation":[{"name":"School of Food and Biological Engineering, Jiangsu University, Zhenjiang 212013, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,12,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1932","DOI":"10.1111\/ijfs.12173","article-title":"Comparison of physicochemical properties of beef potentiators prepared by synergistic fermentation and traditional method","volume":"48","author":"Gao","year":"2013","journal-title":"Int.
