In this study, we addressed various challenges associated with the consumption of functional lipids from theEricerus pela(Chavannes), including unfavorable taste, insolubility in water, difficulty in oral intake, low bioavailability, and low psychological acceptance. Our study focused on the microencapsulation of policosanol, the key active component of insect wax, which is a mixture of functional lipids secreted by theEricerus pela(Chavannes). We developed two innovative policosanol products, microcapsules, and effervescent tablets, and optimized their preparation conditions. We successfully prepared microcapsules containing insect wax–derived policosanol using the spray-drying method. We achieved 92.09% microencapsulation efficiency and 61.67% powder yield under the following conditions: maltodextrin, starch sodium octenyl succinate, and (2-hydroxy)propyl-β-cyclodextrin (HPβCD) at a ratio of 1:1:1, core-to-wall materials at a ratio of 1:10, 15% solid content, spray dryer feed temperature at 60 °C, inlet air temperature at 140 °C, and hot-air flow rate at 0.5 m3/min. The microcapsules exhibited a regular spherical shape with a minimal water content (1.82%) and rapid dispersion in water (within 143.5 s). These microcapsules released policosanol rapidly in simulated stomach fluid. Moreover, effervescent tablets were prepared using the policosanol-containing microcapsules. The tablets showed low friability (0.32%), quick disintegration in water (within 99.5 s), and high bubble volume. The microcapsules and effervescent tablets developed in this study presented effective solutions to the insolubility of policosanol in water. These products were portable and offered customizable tastes to address the psychological discomfort related to insect-based foods, thus providing a novel strategy for the consumption and secondary processing of insect lipids.Keywords:edible insect;functional insect lipids;insect wax–derived policosanol;microcapsules;effervescent tablets

Conventional magnetic effervescent tablet has many drawbacks, such as not practicable for field processing, rapid moisture absorption, and poor tablet storage characteristics. Herein, we developed a novel magnetic effervescent tablet containing ionic liquid microextraction (MET-ILM) for determination of pyrethroids in dairy milk. It contains only Na 2 CO 3 as an alkali source (no acidic source) in the Fe 3 O 4 magnetic tablet; the CO 2 -forming reaction is initiated in the acidic solution containing the analytes, and thus the prepared tablet can be stored for long time periods without deterioration. The combined action of extractant and sorbent vastly increase the extraction efficiency. The optimized procedure consisted of an effervescent tablet, 2:1 HCl:Na 2 CO 3 , and 60 μL [C 6 MIM]PF 6 as extraction solvent. The LODs for five pyrethroids were 0.024–0.075 μg kg −1 with recoveries of 78.3–101.8%. The RSDs were <4.8% and <6.3% for intra- and inter-day precisions. Overall, the method is very feasible for use in the field.

Developing a fast, simple, and efficient sample pretreatment method is of great practical significance for the analysis of complex matrix samples. In this study, a novel multifunctional “four-in-one” effervescent tablet based on switchable hydrophobic deep eutectic solvent (SHDES) was prepared, which can simultaneously facilitate the in situ synthesis of SHDES and CO 2 generation, phase transition, and phase separation. The effervescent tablet based on the SHDES-assisted microextraction (ETA-SHDES-ME) technique was combined with inductively coupled plasma optical emission spectrometry (ICP-OES) for the determination of Pb 2+ in Pinellia ternata (Thunb.) Breit. The important parameters affecting the extraction efficiency of Pb 2+ were optimized using the Box-Behnken design (BBD). The enrichment factor (EF) and limit of detection (LOD) of the established method for Pb 2+ are 31 and 0.2 μg/L, respectively, offering a fast, simple, and eco-friendly approach, and has the application potential of field analysis.

High-performance liquid chromatography (HPLC) determination of phenolic endocrine disrupting chemicals in bottled beverages was carried out using effervescent tablet-assisted switchable hydrophilicity solvent-based microextraction with solidification of floating organic droplets (ETA-SHS-ME-SFO). Octanoic acid was used as the extractant, which is a hydrophobic form of a switchable hydrophilicity solvent. The extractant was generated in-situ by the reaction between sodium octanoate and citric acid and collected after solidification in an ice-bath. Carbon dioxide gas was produced by the reaction between sodium bicarbonate and citric acid, which assisted the extraction of target compounds. Good linearity was obtained over the range of 0.03–3 µg mL −1 , with a correlation coefficient greater than 0.998. The relative recovery varied from 71.7% to 98.1%. The limit of detection ranged from 0.0002 to 0.0007 µg mL −1 . The intra- and inter-day relative standard deviations ( n = 3) were less than 5.8%. Finally, the proposed method was successfully applied to the determination of the levels of bisphenol A, 4-nonylphenol, and 4-tert-octylphenol in bottled water, juice, and energy drink.

Herein, a kind of novel multi-layer core-shell nanocomposites (NSPN) was prepared by employing SiO 2 and polyvinylpyrrolidone (PVP) polymers as modifiers and amino-functionalized metal-organic frameworks (NH 2 -MIL101(Fe)) as coating. It was referred to as the NSPN and ILs-based effervescence-assisted dispersive solid-phase microextraction, hereafter abbreviated as NIE-DSM. In terms of extraction efficiency, SiO 2 and PVP as modifiers and NH 2 -MIL(Fe) as coating onto the surface of NiFe 2 O 4 cores played a synergistically enhancing effect on adsorption/extraction. Effervescent tablets were prepared by integrating the NSPN magnetic nanoparticles as adsorbents with imidazolium-based ionic liquids (ILs) as extractants as well as acidic and alkaline sources. Under vigorous dispersion of CO 2 bubbles, the NIE-DSM method realized the goal of rapidly diffusing and separating the adsorbent/extractant (~3 min) without needing conventional vortexing or centrifugation step. Consequently, the NIE-DSM approach combined dispersion and adsorption/extractant in a synchronous way. Under optimized conditions, the NIE-DSM/HPLC-FLD method gave low limits of detection (0.008–0.034 μg kg −1 ) and satisfactory extraction recoveries (74.1–101.6%) for five polycyclic aromatic hydrocarbons (PAHs; fluorene, anthracene, pyrene, chrysene and benzo(a)pyrene) in milk samples. The intra-day and inter-day precision, expressed as relative standard deviations, was < 5.9% and 6.5%, respectively, demonstrating a high precision. Owing to no requirement for electrical power, this method shows great potential for outdoor monitoring of trace-level PAHs in food matrices.

A novel, simple and rapid method based on magnetic effervescent tablet-assisted ionic liquid dispersive liquid–liquid microextraction (MEA-IL-DLLME) followed by graphite furnace atomic absorption spectrometry (GFAAS) determination was established for the speciation of selenium in various food and beverage samples. In the procedure, a special magnetic effervescent tablet containing CO2 sources (sodium carbonate and sodium dihydrogenphosphate), ionic liquids and Fe3O4 magnetic nanoparticles (MNPs) was used to combine extractant dispersion and magnetic recovery procedures into a single step. The parameters influencing the microextraction efficiency, such as pH of the sample solution, volume of ionic liquid, amount of MNPs, concentration of the chelating agent, salt effect and matrix effect were investigated and optimised. Under the optimised conditions, the limits of detection (LODs) for Se(IV) were 0.021 μg l–1 and the linear dynamic range was 0.05–5.0 μg l–1. The relative standard deviation for seven replicate measurements of 1.0 μg l–1 of Se(IV) was 2.9%. The accuracy of the developed method was evaluated by analysis of the standard reference materials (GBW10016 tea, GBW10017 milk powder, GBW10043 Liaoning rice, GBW10046 Henan wheat, GBW10048 celery). The proposed method was successfully applied to food and beverage samples including black tea, milk powder, mushroom, soybean, bamboo shoots, energy drink, bottled water, carbonated drink and mineral water for the speciation of Se(IV) and Se(VI) with satisfactory relative recoveries (92.0–108.1%).
