The global food waste crisis has significantly contributed to climate change, water pollution, and land degradation. Date palm waste, including seeds, fronds, and fruit pulp residues, represents a valuable source of bioactive compounds with potential applications in food, pharmaceutical, and cosmetic industries. This study presents a comparative evaluation of ultrasound-assisted extraction and other novel extraction techniques, such as pressure-based extraction, pulsed electric fields, microwaves, and natural deep eutectic solvents, for recovering bioactive compounds from date palm waste. These methods were assessed for their efficiency and sustainability in extracting antioxidants and phenolic compounds, and other bioactives while minimizing the use of harmful solvents and high temperatures. Critical factors, such as extraction time, solvent type, temperature, and pressure were crucial indicators to achieve higher extraction efficiencies with lower environmental impacts compared to traditional methods. Additionally, combining these techniques may further optimize the extraction process. This study contributes to the development of sustainable strategies for valorizing date palm byproducts and promoting a circular economy in the food industry. By developing sustainable extraction methods that minimize environmental impacts, this research directly supports the United Nations’ Sustainable Development Goals, particularly SDG 12 (Responsible Consumption and Production) and SDG 13 (Climate Action).

Javanese turmeric (Curcuma xanthorrhiza Roxb.) is known for its diverse pharmacological activities due to its rich phytoconstituents, including curcuminoids and xanthorrhizol. Typically, these compounds are extracted using organic solvents, which pose health and environmental risks. Therefore, safer and more environmentally friendly green extraction methods are being developed. This study investigated the effect of ultrasound-assisted extraction (UAE) combined with natural deep eutectic solvents (NADES) based on choline chloride and organic acids (lactic, malic, and citric acid) to find the best combination for extracting curcuminoids and xanthorrhizol from Javanese turmeric. Results showed that UAE using choline chloride and malic acid (1:1) (ChCl-MA) yielded the best results. The Box–Behnken Design optimized water addition, solvent-to-powder ratio, and extraction time, with optimal conditions being 25 % water addition, a 20 mL/g ratio, and a 15-minute extraction time. This method yielded 4.58 mg/g of curcuminoids and 12.93 mg/g of xanthorrhizol. Furthermore, the ChCl-MA NADES with UAE extraction showed more cytoselective activity towards the HeLa cancer cell line compared to the non-cancer HaCaT cell line. In contrast, traditional ethanol extraction was non-selective, as indicated by similar cell viability reductions in both HeLa and HaCaT cells at 6.25 ppm. Collectively, this study is the first to report the optimal NADES combination with UAE, based on salts and organic acids, for the extraction of Javanese turmeric rhizomes with selective cytotoxic effects against cancer cells. These findings may contribute to the development of novel, naturally derived anticancer agents using green extraction techniques.

Sterile and infection-associated inflammatory diseases are becoming increasingly prevalent worldwide. Conventional drug therapies often entail significant drawbacks, such as the risk of drug overdose, the development of drug resistance in pathogens, and systemic adverse reactions, all of which can undermine the effectiveness of treatments for these conditions. Nanomaterials (NMs) have emerged as a promising tool in the treatment of inflammatory diseases due to their precise targeting capabilities, tunable characteristics, and responsiveness to external stimuli. Ultrasound (US), a non-invasive and effective treatment method, has been explored in combination with NMs to achieve enhanced therapeutic outcomes. This review provides a comprehensive overview of the recent advances in the use of US-mediated NMs for treating inflammatory diseases. A comprehensive introduction to the application and classification of US was first presented, emphasizing the advantages of US-mediated NMs and the mechanisms through which US and NMs interact to enhance anti-inflammatory therapy. Subsequently, specific applications of US-mediated NMs in sterile and infection-associated inflammation were summarized. Finally, the challenges and prospects of US-mediated NMs in clinical translation were discussed, along with an outline of future research directions. This review aims to provide insights to guide the development and improvement of US-mediated NMs for more effective therapeutic interventions in inflammatory diseases.

Meat quality degradation induced by highland transport emphasises the importance of efficient thawing for Tibetan pork quality. The objective of this study was to examine the impact of various thawing methods on the quality characteristics, protein oxidation, and nutrient composition of Tibetan pork. Ultrasound synergized saline thawing (UST) significantly enhanced tenderness and reduced the oxidation degree of myofibrillar protein, improving the Tibetan pork quality. Compared to ultrasound thawing (UT) and saline thawing (ST), UST not only minimized cooking loss (18.44 %) but also restrained the conversion of bound water and fixed water into free water. Furthermore, the unfolding and depolymerization of MP increased surface hydrophobicity (47.96 a.u) and active sulfhydryl content, which stabilized the secondary and tertiary structure of MP. UST also effectively inhibited the decomposition of amino acid metabolites, lipid oxidation, the synthesis of unsaturated fatty acids, and the degradation of free amino acids during thawing. In conclusion, UST accelerated the thawing process while delaying the oxidation of fats and proteins, thus better maintaining the overall quality of Tibetan pork.

Ultrasonic plasticizing micro-injection molding (UPMIM) technology has been considered as an effective means of UHMWPE molding. However, the cumbersome forming process, the degradation of mechanical properties and the poor consistency of molding and property seriously restrict further application. In this study, a new ultrasonic molding method of UHMWPE micro-parts is proposed. Firstly, the UHMWPE ultrasonic plasticizing material was prepared simply and quickly by ultrasonic technology. Secondly, the UHMWPE tensile samples were molded by an innovative UPMIM structure with a large diameter ratio of the ultrasonic sonotrode to plasticizing cavity. Then, the optimum molding process parameters were obtained by grey relational analysis (GRA). After that, the influence of system stability and process parameters on mechanical properties and consistency was studied by contribution analysis. Finally, compared with the typical UHMWPE molding method (compression molding) and the existing research results, the influence and feasibility of the process are analyzed in detail. The results show that the ultrasonic technique can effectively prepare UHMWPE tablets with almost unchanged properties (molecular weight decreased by 0.31 %). A large diameter ratio of the ultrasonic sonotrode to plasticizing cavity can expand the process window for complete filling of UHMWPE tensile samples, and the filling stability of the ultrasonic system is increased by about 1.8 times. Meanwhile, this ultrasonic system structure can also inhibit the oxidative degradation of UHMWPE, reduce the break of molecular chain. The elongation at break (EB) of tensile samples increased from 5.56 % to 12.2 %, while the tensile strength (TS) decreases from 136.54 % to 68.11 %. Moreover, the contribution of process parameters to the mechanical properties and consistency for UHMWPE tensile samples is 55.97 %–88.37 %, while the contribution of ultrasonic system stability is 11.63 %–44.03 %.

Bletilla striata, a medicinal orchidaceous plant, is recognized for its significant pharmacological value. However, the lack of comparative metabolomic data across different extraction methods for analyzing its bioactive components has significantly undervalued the application potential of B. striata in the traditional Chinese medicine market. Using six ultrasound-assisted extraction methods and UPLC-MS/MS, this study identified 1,945 metabolites in B. striata extracts. The dominant categories were lipids (51.35%), flavonoids (18.00%), and phenolic acids (12.51%). KEGG analysis revealed alterations in flavonoids and isoflavonoids biosynthesis pathways. Thirteen bitter metabolites, including cinnamic acid, were identified in B. striata tubers, underscoring their potential pharmacological applications, such as anti-inflammatory, antioxidant and antibacterial activities. Optimizing different extraction methods can better preserve the bioactive components of B. striata extracts, thereby enhancing its potential applications in the food and pharmaceutical industries.

In recent years, the development of zero-trans fatty acid products instead of traditional hydrogenated and high-unsaturated fatty acid animal and vegetable oils has been an increasing interest in the field of food. This paper focused on the ultrasound-assisted preparation of a novel wax-based composite gelator loaded with natural antioxidant to prepare oleogels with good storage oxidation stability. The preparation of the wax-based composite gelator was to first form the anthocyanin (ACNs) and soyabean lecithin (SL) complex, and then homogenized with beeswax (BW). A complex maximum association efficiency of 86.43 % was achieved when the combination was performed for 50 min at 40 °C and 270 W ultrasonic power, and exhibited higher lipophilicity. Moreover, structural analysis results revealed that ultrasonic-assisted treatment accelerated the formation of ACNs and SL ultrasonic complexes (ASUC) by the hydrogen bonding. The results of gelators indicated the ASUC-BW composite gelator showed the highest ACNs embedding rate of 72.91 % and better antioxidant activity. XRD analysis and thermogravimetric analysis demonstrated that ASUC-BW composite gelator maintained β′ crystal structure and had higher thermal stability due to physical interactions between ASUC and beeswax. Accelerated storage tests at 60 °C revealed that oleogels prepared by ASUC-BW composite gelator (ALO) had significantly lower peroxide values (PV) (14.0 mmol/kg) and thiobarbituric acid reactive substances (TBARS) (1.8 mg/kg). Overall, this paper demonstrates ultrasonic-assisted treatment is an effective way to improve dispersion and availability of ANCs in food rich in oil and can be further applied to developing novel high stability fatty food systems.

Sonochemical and sonophysical activities were investigated under various geometric conditions using 28 kHz double-bath-type sonoreactors. Sonochemical activity was quantified using KI dosimetry (triiodide ion concentration), while sonophysical activity was measured via lightweight expanded clay aggregate (LECA) desorption tests (turbidity). Thirty-five different geometric conditions were tested, comprising seven distances between the sonoreactor bottom and vessel bottom (L2) and five water levels (L3). The optimal conditions for sonochemical activity [(L2/L3, unit: mm): 70/76, 90/116, 70/116, 110/146, and 70/96] and sonophysical activity [(L2/L3, unit: mm): 30/78, 70/88, 150/168, 30/68, and 30/38] did not match, and no conditions showing high values in both activities were found. The presence of a thin-walled vessel did not affect ultrasound transmission. However, the presence of LECAs caused a large attenuation of ultrasound and the formation of different cavitational active zones in the vessel. This was identified as the main reason for the mismatch in optimal geometric conditions for sonochemical and sonophysical activities. The sonochemical activity could be enhanced by the presence of LECAs under conditions; however, the enhanced sonochemical activity was much lower than the five highest sonochemical activities. In addition, the movement of LECAs induced by ultrasound irradiation significantly enhanced the sonophysical activity.

Mannosylerythritol lipid-A (MEL-A) is a kind of novel biosurfactant and has great potential to apply into food and pharmaceutical field with its outstanding physicochemical and biological property. In this study, Thyme essential oil (TEO) microcapsules based on MEL-A were prepared through ultrasonic emulsification and characterized by size, morphology, structure, antioxidant and antibacterial activity. The results showed the optimal preparation condition was the duration of 15 min and power intensities of 400 W/cm2 through ultrasound treatment, improving the solubility and applicability of TEO. Further experiment explored the physicochemical properties and biological activity of TEO microcapsules, measuring a particle size of 276.19 ± 1.72 nm with good dispersibility. FT-IR, X-ray, and TEM confirmed the successful encapsulation of the essential oil within the microcapsules. Meanwhile, the antioxidant and antibacterial properties of microcapsules were assayed and microcapsules with 7 % MEL-A exhibited better antioxidant properties, while those containing 13 % MEL-A showed better antibacterial performance. In conclusion, MEL-A showed obvious structural stability and functional enhancement in TEO-loaded microcapsules, indicating that its potential applications in food preservation and food machinery sterilization are numerous.

Extraction of bioactive compounds from vegetal matrices is a dynamic field in pharmaceutical, cosmetic and food industry. Many of these compounds have high medicinal value. Ultrasonic assisted extraction (UAE) becomes an interesting alternative to reduce both the amount of chemical solvents and the processing time.
The aim of the present paper is to introduce, intuitively, the physical mechanisms involved in ultrasonic extraction for non-specialists.
Two different mechanisms, cavitation and acoustic streaming, can be easily experimentally shown. The proposed experiment is the extraction of the sugar cover in sugar-coated chocolates. Extraction is analyzed using video tools to obtain a quantitative evolution of the process. Graphical results and videos are a useful tool for showing the basis of ultrasonic extraction in several levels from primary school to university students. In the event that the necessary ultrasound equipment is not available, we hope that the videos available in the supplementary material will be useful for teaching the topic.
