为了满足饥饿人口的需求，至关重要的是提高农产品产量，同时最大限度地减少受污染的废物。脉冲电场 (PEF) 和非热等离子体 (NTP) 这两种非热技术的使用每天都在增加。由于 PEF 和 NTP 都是相对较新的领域，因此对这两种技术及其作用模式的了解有限。研究表明，PEF 对植物种子的处理有助于发芽和幼苗生长。 PEF 强度的积极影响很大程度上取决于种皮类型和植物种类。另一种非热技术 NTP，在有或没有不同进料气体的不同压力下产生时，会影响种子发芽、幼苗生长、产量和对非生物胁迫的恢复能力。经NTP处理的幼苗的早期发芽率、发芽率和发芽率均得到提高。与 PEF 处理类似，NTP 对发芽有负面影响或没有影响。本文综述了PEF和NTP对种子萌发的影响，并分析了其正面或负面影响的情况和机制。使蛋白质和酶失活以延长饮料的保质期是 PEF 和 NTP 的另一个突出应用。 PEF 和 NTP 与蛋白质的相互作用有助于理解这些技术的微观机制。因此，我们在这篇综述中介绍了 PEF 和 NTP 导致的蛋白质/酶的潜在结构和功能变化，以及这两种技术的优点和缺点的比较。
To meet the needs of the hungry population, it is critical to boost agricultural product production while minimizing contaminated waste. The use of two nonthermal technologies, pulsed electric field (PEF) and nonthermal plasma (NTP), is increasing every day. As both PEF and NTP are relatively newer areas, there is limited knowledge about these two technologies and their modes of action. Studies showed that PEF treatment on the plant seeds helps germination and seedling growth. The positive impact of PEF intensity is highly dependent on the seed coat type and plant species. Another nonthermal technology, NTP, affects seed germination, seedling growth, yield, and resilience to abiotic stress when generated at varying pressures with and without different feed gases. Early germination, germination rate, and germination percentage were all improved when the seedlings were treated with NTP. Similarly to the PEF treatment, NTP had a negative or no effect on germination. This review examined the effects of PEF and NTP on seed germination and analyzed the situation and mechanism behind the positive or negative effect. Deactivation of proteins and enzymes to extend the shelf life of beverages is another prominent application of PEF and NTP. The interaction of PEF and NTP with proteins aids in understanding the microscopic mechanism of these technologies. Therefore, we covered in this review the potential structural and functional changes in proteins/enzymes as a result of PEF and NTP, as well as a comparison of the benefits and drawbacks of these two technologies.
