Abstract

Nitric oxide (NO) generation-enhanced atmospheric-pressure plasma technology has been investigated as a nonthermal intervention technology for prolonging the ripening period of tomatoes. UV-irradiated dielectric barrier discharge plasma reaches the NO-enhanced mode earlier, and NO is rapidly involved in the inhibition of tomato respiration. With as little as 26 W of power in total, the NO-processing of tomatoes using plasma technology helps control the postripening of tomatoes. The NO-enrichment mechanism was analyzed through numerical calculations, which revealed that the photolysis of ozone (O₃) and nitrous acid (HONO) occurred during UV irradiation. The measured amount of CO₂ emitted from plasma-treated tomatoes was ~ 300 ppm lower than that emitted from nontreated tomatoes, indicating that metabolism and respiration were inhibited. In addition, the NO-enhanced plasma treatment of tomatoes is considered to be more effective because the so-treated tomatoes emitted 100 ppm less CO₂ than the plasma-treated tomatoes. The delay of respiration through plasma treatment can help prevent color changes or decreases in the firmness of tomatoes.

空气等离子体氧化氮处理延长番茄保质期的研究

研究了一氧化氮（NO）生成增强常压等离子体技术作为延长番茄成熟期的非热干预技术。紫外线照射的介质阻挡放电等离子体较早到达NO增强模式，NO快速参与抑制番茄呼吸。利用等离子体技术对番茄进行no处理，总功率只有26瓦，有助于控制番茄的后条纹。通过数值计算分析了no富集机理，揭示了紫外照射下臭氧（O3）和亚硝酸（HONO）的光解作用。经过等离子处理的番茄释放出的二氧化碳比未经等离子处理的番茄低300 ppm，这表明等离子处理后的番茄代谢和呼吸受到抑制。此外，对番茄进行no增强等离子体处理被认为更有效，因为经过no处理的番茄比等离子体处理的番茄排放的二氧化碳少100 ppm。通过等离子体处理延缓呼吸可以帮助防止西红柿颜色变化或硬度下降。

期刊介绍： Publishing original papers on fundamental and applied research in plasma chemistry and plasma processing, the scope of this journal includes processing plasmas ranging from non-thermal plasmas to thermal plasmas, and fundamental plasma studies as well as studies of specific plasma applications. Such applications include but are not limited to plasma catalysis, environmental processing including treatment of liquids and gases, biological applications of plasmas including plasma medicine and agriculture, surface modification and deposition, powder and nanostructure synthesis, energy applications including plasma combustion and reforming, resource recovery, coupling of plasmas and electrochemistry, and plasma etching. Studies of chemical kinetics in plasmas, and the interactions of plasmas with surfaces are also solicited. It is essential that submissions include substantial consideration of the role of the plasma, for example, the relevant plasma chemistry, plasma physics or plasma–surface interactions; manuscripts that consider solely the properties of materials or substances processed using a plasma are not within the journal’s scope.
