A few applications, such as the manufacturing of certain vegetable beverages and beer, offer considerable potential for industrial applications. However, resistance to innovation and possibly the issue of capital costs needed to replace or integrate existing installations can represent important barriers. Further promising application fields concern the manufacturing of dry extracts rich in bioactive compounds from plant resources. However, water removal steps account for most of the energy consumption, thus as high as possible biomass concentration should be used, which sets the design and test of effective strategies to intensify cavitation as a research priority. This short review surveys the most recent studies and proposes practical recommendations toward the actual industrialization of HC processes.</div></div>","PeriodicalId":292,"journal":{"name":"Current Opinion in Chemical Engineering","volume":"48 ","pages":"Article 101140"},"PeriodicalIF":8.0,"publicationDate":"2025-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143898767","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Experimental data from 53 cases across 15 studies were analyzed, and synergistic effects were evaluated. In only-PS processes, significant activation below 40°C was rarely observed, with few exceptions. Although several researchers reported high synergistic effects in US/PS processes, most cases showed low or negligible synergistic effects. High synergistic effects were attributable to incomplete cooling systems, low pollutant concentrations, and high PS/pollutant ratios. Therefore, the ability of acoustic cavitation to activate PS without thermal activation induced by US attenuation below 40°C remains debatable.</div></div>","PeriodicalId":292,"journal":{"name":"Current Opinion in Chemical Engineering","volume":"48 ","pages":"Article 101136"},"PeriodicalIF":8.0,"publicationDate":"2025-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143865031","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
