Summary: This study introduces an innovative method of enhancing the production of essential oils from Mellissa officinalis L. by using ultrasonic and microwave-coupled Clevenger hydrodistillation and a proprietary distillation device (PDD). The maximum extraction yield of 0.21±0.0019% was achieved by optimizing the liquid-to-solid ratio, microwave extraction power, and microwave extraction time. The new process produced significantly higher yields compared to the electric furnace heating-assisted PDD and the microwave-assisted traditional Clevenger hydrodistillation, showing great potential for improving the production efficiency of M. officinalis essential oils.

Summary: This study investigated the effects of ultrasound-assisted (UAE), microwave-assisted (MAE), and ultrasound-microwave-assisted (UMAE) methods on pectin extraction from industrial tomato waste. The best extraction conditions were determined based on a fuzzy analytical method, considering pectin yield, galacturonic acid, and lycopene content. The results showed that UAE conditions with pH 1.5 and solid liquid (SL) ratio 1:30 resulted in high pectin yield and lycopene content. MAE conditions with 300 W power for 10 min yielded high pectin yield and galacturonic acid content. Moreover, the combination of UAE and MAE (UMAE) further improved the pectin yield compared to individual methods. However, the FTIR spectra of the obtained pectins showed similar structures regardless of the extraction technique.

Summary: This study investigates the potential of eliminating washing step in glucose recovery and ethanol production scheme when DES pretreatment is applied. The most suitable DES for pretreating sugarcane bagasse was found to be ChCl-MA, which resulted in high sugar recovery and low sugar loss during the process. The maximum amount of glucose recovered after 48 hours of enzymatic hydrolysis from both washed and unwashed pretreated substrate was insignificantly different, but slightly higher bioethanol was obtained from the unwashed pretreated substrate compared to the washed substrate.

Summary: In this study, an ionic covalent organic framework (iCOF) surface grafting monolithic sorbent was prepared for in-tube solid-phase microextraction (SPME) of aristolochic acids (AAs) in various samples. The density of quaternary ammonium ions in the iCOF was modulated for enhanced adsorption of AAs. The iCOF surface grafting monolithic sorbent was confirmed by different means. Several operating conditions were optimized to develop the online in-tube SPME-HPLC method, which showed good linearity, low limits of detection, and high recoveries for AAs in serum samples. This study presents a feasible approach for the application of COF-based monolithic sorbents in sample preparation.

Summary: A chitosan-alginate sponge with multiple cross-linking networks was developed for adsorption and enrichment of anionic dyes from food samples. The sponge showed better three-dimensional network structure, mechanical behavior, and stability compared to pure chitosan and alginate sponges. The adsorption performance and selectivity of the sponge were systematically studied, and it maintained high adsorption capacity and selectivity for anionic dyes. The sponge also showed satisfactory reusability and was successfully combined with high-performance liquid chromatography for the enrichment and detection of anionic dyes in candy and cocktail samples.
