The quality of licorice extract is dictated by the drying process. The commonly used drying methods of licorice extract are not efficient in obtaining high\u2010quality products so alternative techniques need to be developed and researched. In this study, ultrasound\u2010assisted vacuum drying (UAVD) was first utilized to improve drying efficiency and produce a higher\u2010quality product. The changes in water mobility of licorice extract during drying were characterized using low\u2010field nuclear magnetic resonance. In addition, the effects of ultrasonic power on the drying dynamics, the contents of liquiritin and glycyrrhizic acid, the antioxidant capacity and the microstructure formation of licorice extract during the whole drying process were investigated.<\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS<\/jats:title><jats:p>The drying times for licorice extract to reach equilibrium moisture content were reduced by 9.09\u201369.70% with UAVD at 40\u2013200\u2009W compared with that without ultrasonic treatment (0\u2009W). Moreover, the proportions of bound water and semi\u2010bound water in fresh concentrate were 3.75% and 96.25%. It was also found that high ultrasonic power promoted the flow of water and the formation of porous structure in licorice extract, which led to the improvement of drying efficiency. The contents of liquiritin (2.444%) and glycyrrhizic acid (6.514%) were retained to a large degree in the dried product at an ultrasonic power of 80\u2009W. The DPPH inhibition rate of UAVD samples with different ultrasonic powers ranged from 84.07\u2009\u00b1\u20090.46% to 90.65\u2009\u00b1\u20090.22%.<\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSION<\/jats:title><jats:p>UAVD has the advantages of high efficiency and low energy consumption, which may be an alternative technology for vacuum drying widely used in industry. \u00a9 2024 Society of Chemical Industry.<\/jats:p><\/jats:sec>","DOI":"10.1002\/jsfa.13283","type":"journal-article","created":{"date-parts":[[2024,1,22]],"date-time":"2024-01-22T13:54:52Z","timestamp":1705931692000},"page":"4004-4014","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Effects of ultrasonic power on drying kinetics and product quality of licorice extract during ultrasound\u2010assisted vacuum drying"],"prefix":"10.1002","volume":"104","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6643-407X","authenticated-orcid":false,"given":"Xuecheng","family":"Wang","sequence":"first","affiliation":[{"name":"Key Laboratory of Modern Preparation of Traditional Chinese Medicine, Ministry of Education Jiangxi University of Chinese Medicine  Nanchang China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaohui","family":"Wang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Modern Preparation of Traditional Chinese Medicine, Ministry of Education Jiangxi University of Chinese Medicine  Nanchang China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yutian","family":"Zhang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Modern Preparation of Traditional Chinese Medicine, Ministry of Education Jiangxi University of Chinese Medicine  Nanchang China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yaqi","family":"Wang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Modern Preparation of Traditional Chinese Medicine, Ministry of Education Jiangxi University of Chinese Medicine  Nanchang China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuanhui","family":"Li","sequence":"additional","affiliation":[{"name":"Key Laboratory of Modern Preparation of Traditional Chinese Medicine, Ministry of Education Jiangxi University of Chinese Medicine  Nanchang China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yaokun","family":"Xiong","sequence":"additional","affiliation":[{"name":"School of Pharmacy Jiangxi University of Chinese Medicine  Nanchang China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ming","family":"Yang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Modern Preparation of Traditional Chinese Medicine, Ministry of Education Jiangxi University of Chinese Medicine  Nanchang China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaorong","family":"Luo","sequence":"additional","affiliation":[{"name":"Research Center of CR Jiangzhong Pharmaceutical Group Co.
