In this sense, ultrasound-assisted extraction (UAE) has emerged as a promising technology for fast and efficient extraction of natural products without high organic solvent consumption. However, most studies on UAE are focused on laboratory scale. In order for this technology to be suitable for industrial applications, more pilot studies need to be developed and discussed. In this sense, this review aimed to address scale-up applications of UAE of natural products developed from 2019 to the first semester of 2024. Applications involving hydrodynamic cavitation were not included in this review. Key parameters related to ultrasound were addressed, such as reactor configuration, process type (batch or continuous), frequency, and others. Furthermore, the major challenges associated with the upscaling of UAE, as well as current trends and future perspectives were discussed. It was observed that flow cells were the main reactor type used in scale-up UAE of natural products and that flow-through was the main operation mode. The use of these devices enabled processing of higher sample volumes, possibly due to more homogeneous energy distribution in the reactor. Hence, further enhancements in this area should be expected. Furthermore, phenolic compounds were the main targets of extraction and low frequencies (<100 kHz) were used. However, a challenge remains regarding the lack of essential information in several publications, which makes comparison between studies difficult, as well as their reproduction. Nevertheless, scale-up UAE of natural products is a promising research area.</div></div>","PeriodicalId":292,"journal":{"name":"Current Opinion in Chemical Engineering","volume":"48 ","pages":"Article 101120"},"PeriodicalIF":8.0,"publicationDate":"2025-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143682639","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}

Although a variety of treatment methods exist, their performance needs to be improved to enable selective separation with increased durability and fouling resistance. To achieve this, we need to gain a better understanding of how molecular-level physics and chemistry impact integrated systems. Regarding current research on water treatment techniques, there is a clear need to study such systems under realistic environmental conditions. In this review, we aim to show that X-ray spectroscopic techniques are uniquely positioned to provide such information by obtaining detailed molecular insight into phenomena relevant to water research. By doing so, we hope to accelerate the rational design of novel treatment materials and processes. Specifically, a deeper understanding of the complex and interconnected phenomena that impact multilevel water treatment processes will lead to the successful development of next-generation water purification technologies.</div></div>","PeriodicalId":292,"journal":{"name":"Current Opinion in Chemical Engineering","volume":"48 ","pages":"Article 101103"},"PeriodicalIF":8.0,"publicationDate":"2025-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143446075","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
