Conventional extraction methods using organic solvents have long been employed for this purpose, but their significant drawbacks highlight the need for alternative approaches. This review explores the application of non-thermal ultrasound-assisted extraction (UAE) with deep eutectic solvents (DESs) for extracting valuable substances from agro-food waste. It critically examines recent innovations in the UAE with DESs, including mechanisms, applications to agro-food waste, limitations, and aspects of safety, sustainability, and scalability. The key findings indicate that UAE with DESs outperforms conventional and other novel extraction techniques for agro-food waste valorization. This approach offers significant benefits, such as enhanced extraction efficiency, high-quality extracts, reduced processing time and energy consumption, biodegradability, low toxicity, and the reusability and tunability of DESs, all of which align with eco-friendly practices. While identifying a single best DES is challenging due to their varying extraction efficiencies with different waste materials, but optimal ultrasonication parameters commonly reported in the literature include 300-400 W power, 30 min extraction time, 40 °C temperature, and a solid-to-solvent ratio (SSR) of 1:30 g/mL to achieve high extraction efficiency. Future studies should investigate a wider range of plant and animal-based waste, optimize ultrasonic parameters and DES compositions, explore combinative extraction methods, enhance compound purification and solvent recovery, and assess industrial scalability through TEA, LCA, safety testing, and regulatory alignment.</p>","PeriodicalId":442,"journal":{"name":"Ultrasonics Sonochemistry","volume":"120 ","pages":"107500"},"PeriodicalIF":9.7,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12356026/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144811602","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Building upon these findings, the present study established a tightly controlled in vitro biomimetic fermentation system, complemented by ultrasound-assisted extraction and multi-omics analyses, to faithfully reconstruct and elevate the hallmark flavour of civet coffee. Leveraging metagenomic data from the civet gut, thirty core functional strains were selected from 1870 isolates to create a synthetic symbiotic consortium. Fermentation parameters were optimised in three stages-single-factor experiments, Box-Behnken response-surface design, and a genetic-algorithm-artificial-neural-network (GA-ANN) model. Fermentation products were recovered by ultrasound-assisted extraction (40 kHz, 400 W, 10 min); volatile and non-volatile metabolites were quantified in both targeted and untargeted modes via GC-MS and UHPLC-MS/MS, and their temporal dynamics were deciphered through time-series clustering and metabolic-network analysis. The optimal conditions-16.5 % inoculum, initial pH 6.25, 33 ℃, 135 h-yielded an average SCA cupping score of 82.92, with a maximum of 85.25, significantly higher than those of natural fermentation and conventional civet coffee (P < 0.05). Total acidity increased to 0.78 g L^-1, total polyphenol content reached 225.3 mg L^-1, and key bioactive compounds remained stable. GC-MS quantification showed 1.9-2.3-fold increases in 2,3-dimethoxyphenol, phenylethanol, and 5-methylfurfural, alongside 63 % and 41 % reductions in 2-methylpyrazine and caffeine, respectively. Multi-omics evidence indicated that lipid β-oxidation, the amino-acid Ehrlich pathway, and esterification jointly enriched fruity, nutty, and floral notes; the elevated copy numbers of ndmA/B and pyoA/B genes underpinned the attenuation of bitter compounds. Relative to conventional solvent and Soxhlet extraction, ultrasound-assisted extraction improved volatile recovery by approximately 28 %, reduced energy consumption by ≥66 %, and halved solvent usage. Overall, this work achieves a high-fidelity in vitro replication of the civet gut microbiome and its metabolic functions, enables precision flavour modulation through intelligent optimisation and green extraction, and demonstrates industrial feasibility-the processing cost per kilogram of raw beans is 76.7 % lower than that of the traditional animal-derived method.</p>","PeriodicalId":442,"journal":{"name":"Ultrasonics Sonochemistry","volume":"120 ","pages":"107499"},"PeriodicalIF":9.7,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12357160/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144815499","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
