With the proposal of the Paris Climate Agreement and double carbon policy, production enterprise is now facing green and low-carbon transformation. To promote green and low-carbon development, optimizing the production process and improving utilization rate of raw materials for the reduction of production cost is an significant technological path for the plant extract industry. Thus, the aim of this work was to develop a consecutive extraction process of pectin and hesperidin with lower cost and higher purity, as well as better properties of extract. The process parameters will be put forward through single-factor experiments, Plackett-Burman design and Box-Behnken design. The experimental results showed that the consecutive extraction process was effective and feasible. Pectin with excellent properties was obtained, and the solid-liquid ratio of extraction process parameters of hesperidin was reduced to 1:8 (g: mL). The problems of environmental pollution and high energy consumption in traditional extraction could be solved. The consecutive extraction process, an innovative, economic and environmental-friendly process, may be realized easily in industrial application. At the same time, the consecutive extraction process mechanism was revealed with the help of microscopy analysis of the plant tissue structure. The results demonstrated that preferential extraction of pectin process was helpful for the exposure and dissolution of hesperidin crystallization in cells and thus can improve extraction efficiency of hesperidin. The purity of the obtained hesperidin was up to 91.7%, which can be further purified depending on application requirements. A large amount of pectin was obtained (23.3% ± 0.5% yield), and the pectin has superior gel-property, strong antioxidant activity and certain antibacterial activity. The pectin and hesperidin obtained will have better application prospects in medicine and food because of their unique characteristics.

This study investigated Huangshui fluid pretreatment effects on rice hull's physical properties and furfural removal, revealing optimal conditions (solid-liquid ratio 1:15, pH 3.2, 60 °C, 6 days) achieving furfural reduction to 68.55 ± 0.33 mg/100 g (below harmful thresholds), while reducing test weight to 87.04 ± 0.749 g/L ( p < 0.05) without compromising water absorption/elasticity ( p > 0.05). Gas chromatography demonstrated Huangshui-treated rice hulls enhanced crude Baijiu quality: acetaldehyde decreased 38.30 % ( p < 0.01), furfural 49.02 % ( p < 0.01), methanol 9.37 %, fusel oil 6.31 %, while hexanoic acid increased 25.22 %, ethyl hexanoate 69.95 %, and four major esters 24.45 %. The pretreatment significantly improved mash looseness and flavor profiles, confirming its feasibility for reducing harmful compounds and upgrading Baijiu quality through effective impurity removal and ester enrichment.

We specially carried out the subcritical butane extraction to separate abamectin from tea leaves. Four parameters, such as extraction temperature, extraction time, number of extraction cycles, and solid-liquid ratio were studied and optimized through the response surface methodology with design matrix developed by Box–Behnken. Seventeen experiments with three various factors and three variable levels were employed to investigate the effect of these parameters on the extraction of abamectin. Besides, catechins, theanine, caffeine, and aroma components were determined by both high-performance liquid chromatography and gas chromatography–mass spectrometry to evaluate the tea quality before and after the extraction. The results showed that the extraction temperature was the uppermost parameter compared with others. The optimal extraction conditions selected as follows: extraction temperature, 42°C; number of extraction cycles and extraction time, 1 and 30 min, respectively; and solid–liquid ratio, 1:10. Based on the above study, the separation efficiency of abamectin was up to 93.95%. It is notable that there has a quite low loss rate, including the negligible damage of aroma components, the bits reduce of catechins within the range of 0.7%–13.1%, and a handful lessen of caffeine and theanine of 1.81% and 2.6%, respectively. The proposed method suggested subcritical butane possesses solubility for lipid–soluble pesticides, and since most of the pesticides are attached to the surfaces of tea, thus the as-applied method was successfully effective to separate abamectin because of the so practical and promising method.

The increasing diesel pollution accidents pose a serious threat to the ecological environment and human health. Remediation of diesel-contaminated soil (DCS) has attracted widespread attention during the past few decades. This work proposed an approach for the remediation of DCS by alkoxyethanol aqueous two-phase extraction (ATPE), which was an application of this small molecule aqueous two-phase system (ATPS). In addition, the influence of temperature, stirring speed, stirring time, and solid–liquid ratio on the removal of diesel was explored respectively. The removal efficiency of diesel could reach more than 97.18% in 18 min. Meanwhile, ATPS had high reusability, and the removal efficiency remained above 85.17% in the reuse process. Alkoxyethanol ATPE could effectively remove diesel hydrocarbons with different carbon chain lengths and the remediation process hardly caused residual organic solvents on the soil surface according to the analysis of gas chromatography-mass spectrometry (GC–MS) and Fourier transforms infrared (FT-IR), which could be regarded as the distinct advantage compared to the traditional surfactant washing method and organic solvent extraction method. The study of soil physicochemical properties and wheat germination proved that the soil structure and properties changed little after ATPE remediation. And finally, the mechanism of alkoxyethanol ATPE was intensively discussed according to the remediation characteristic. This work provided an efficient method for the remediation of DCS and widened the application fields of alkoxyethanol ATPS as well. Graphical abstract
