The nanofibers formed by electrospinning technology have the advantages of orderly release mechanism and controllable dissolution rate. However, the use of toxic and harmful organic solvents is widespread in the field of electrospinning, which not only poses a potential hazard to human health and the natural environment, but also increases the manufacturing cost and difficulty of electrospinning. Therefore, the purpose of this paper is to introduce the application of green electrospinning technology in food engineering. Water solvent electrospinning is mainly introduced, and some water-soluble biopolymer and synthetic polymers are reviewed. Their latest applications and development limitations in the field of food engineering are introduced and discussed. The water solvent electrospinning introduced here transforms a process that has adverse effects on the environment and health into a scalable and ecologically conscious “green” electrospinning, which is both important and timely and will bring exemplary changes to the field of food engineering.

“…Pesticide residues pose a significant threat not only to non-target organisms but also to the overall ecology of soil and water [83][84][85]. Therefore, conducting tests for pesticide residues in soil, water, and food is crucial for mitigating potential health risks [86,87]. However, analyzing trace amounts of polar contaminants accurately in samples, owing to the complexity of the matrix and the low concentration of the target analytes, has long been a challenging and critical area in separation techniques.…”

This review delves into the diverse applications of ionic liquids (ILs) in modern agriculture, focusing on their pivotal roles in the extraction of natural products and pesticides, as well as their substantial significance in sustainable pesticide delivery systems. The reported extraction methods include ILs and their modified materials as solvents in dispersive liquid–liquid microextraction, solid-phase dispersion, and solid-phase microextraction. The study categorizes ILs according to their utility as herbicides, microbicides, food repellents, and plant growth regulators. This review investigates the use of ILs as plant immunity inducers to elevate the systemic acquired resistance in crops, thereby augmenting their intrinsic ability to defend against plant pathogens. Furthermore, the review explores the application of ILs in pesticide delivery systems, emphasizing their ability to enhance efficacy while promoting environmental sustainability. The biodegradability and toxicity aspects of ILs are also discussed, shedding light on their potential as eco-friendly alternatives in agricultural practices. In conclusion, this comprehensive overview underscores the multifaceted contributions of ILs in agriculture, from efficient extraction methods to the development of innovative and sustainable pesticide delivery systems. As the agricultural landscape evolves towards environmentally conscious practices, the integration of ILs presents a promising avenue for enhancing productivity while minimizing ecological impact. As the agricultural industry seeks innovative and sustainable solutions, the nuanced exploration of ILs in this review highlights their potential to address multiple challenges in modern farming practices.

“…9,10 Currently, micro-solid-phase extraction techniques have attracted considerable attention due to their ease of setup, exceptional efficiency, rapidity, and minimal adsorbent and solvent usage. 11 Consequently, micro-solid phase extractionpipette tip (PT-SPE) has emerged as a modern, cost-effective, rapid, effective, and environmentally friendly method for preconcentrating diverse analytes including drugs, peptides, and proteins. [12][13][14] In the PT-SPE technique, the amount of adsorbents applied in the pipette tip and the use of harmful organic solvents are significantly reduced.…”
