摘要

经试验，可延长香蕉贮存的保质期。冷等离子体是一种环保的抗菌技术，有可能提高新鲜水果和蔬菜的保质期。非平衡大气压微秒脉冲直接阻挡放电等离子体(mspDBD或“冷等离子体”)对香蕉保质期的影响。香蕉在室温常压常湿条件下暴露于等离子体处理空气中1周。研究了香蕉的重量、颜色、表面形态和糖含量的变化。等离子体处理没有引起霉菌生长，未处理的样品在储存后观察到霉菌生长，而等离子体处理的样品没有霉菌生长。本研究表明，与传统方法相比，mspDBD技术通过在收获后的储存条件下抑制病原菌的生长，有可能延长香蕉的保质期。

Enhancing Shelf Life of Bananas by Using Atmospheric Pressure Pulsed Cold Plasma Treatment of the Storage Atmosphere

been tested to extend the shelf life of banana storage. Cold plasma is an environmentally friendly antimicrobial technology with the potential to enhance the shelf life of fresh fruit and vegetables. nonequilibrium atmospheric pressure microsecond-pulsed direct barrier discharge plasma (mspDBD or “cold plasma”) on the shelf life of bananas. Bananas were exposed to plasma-treated air for 1 week at room temperature and normal pressure and humidity. The change in weight, color, surface morphology, and sugar content of bananas was investigated. Plasma treatment caused no ally, mold growth was observed in untreated samples after storage, but was absent in plasmatreated samples. This study demonstrated that the mspDBD technique has the potential to prolong the shelf life of bananas compared with conventional methods by inhibiting pathogen growth in post-harvest storage conditions.

期刊介绍： Technology has always played an important role in medicine and there are many journals today devoted to medical applications of ionizing radiation, lasers, ultrasound, magnetic resonance and others. Plasma technology is a relative newcomer to the field of medicine. Experimental work conducted at several major universities, research centers and companies around the world over the recent decade demonstrates that plasma can be used in variety of medical applications. It is already widely used surgeries and endoscopic procedures. It has been shown to control properties of cellular and tissue matrices, including biocompatibility of various substrates. Non-thermal plasma has been demonstrated to deactivate dangerous pathogens and to stop bleeding without damaging healthy tissue. It can be used to promote wound healing and to treat cancer. Understanding of various mechanisms by which plasma can interact with living systems, including effects of reactive oxygen species, reactive nitrogen species and charges, has begun to emerge recently. The aim of the Plasma Medicine journal will be to provide a forum where the above topics as well as topics closely related to them can be presented and discussed. Existing journals on plasma science and technology are aimed for audiences with primarily engineering and science background. The field of Plasma Medicine, on the other hand, is highly interdisciplinary. Some of prospective readers and contributors of the Plasma Medicine journal are expected to have background in medicine and biology. Others might be more familiar with plasma science. The goal of the proposed Plasma Medicine journal is to bridge the gap between audiences with such different backgrounds, without sacrificing the quality of the papers be their emphasis on medicine, biology or plasma science and technology.
