Abstract

The climacteric nature of tomatoes results in the rapid deterioration of the fruit which in turn reduces the shelf-life. Herein, the role of N,N,N-trimethyl chitosan zinc oxide nanoparticles (NTMC-ZnONPs) and the additive advantage in the quality and/or shelf-life extension of post-harvested tomato fruits was investigated. NTMC-ZnONPs was synthesized through green reduction of zinc salt in the presence of clean hydrogen gas and water-soluble N,N,N-Trimethyl chitosan as a stabilizing agent. The UV–Vis spectroscopic measurement shows that NTMC-ZnONPs exhibit a strong surface plasmon resonance at 360 nm which is true for ZnONPs. The detailed characterization of NTMC-ZnONPs confirmed the formation of ZnONPs with an average particle size of 37.6 nm. Furthermore, varied concentrations of NTMC-ZnONPs were applied by dipping unblemished tomato fruit in the solution of NTMC-ZnONPs for 60 s and thereafter stored in a plastic container. Physicochemical quality parameter data of the NTMC-ZnONPs-treated tomato fruit were collected, namely: color, total suspended solids (TSS), vitamin C, lycopene, pH, β-carotene, shelf life, and firmness. NTMC-ZnONPs were found to significantly improve the fruit firmness, color, β-carotene content, shelf-life, and taste of tomato fruit while the TSS was found to increase as ripening progresses. Therefore, this study ascertains the applicability and/or suitability of green NTMC-ZnONPs in the enhancement of fruit quality when coated with NTMC-ZnONPs during storage.

氢辅助合成N,N,N-三甲基壳聚糖稳定氧化锌纳米粒子及其对番茄品质的影响
番茄的更年期特性导致果实迅速变质,从而缩短了保质期。本文研究了N,N,N-三甲基壳聚糖氧化锌纳米颗粒(NTMC-ZnONPs)在番茄采后果实品质和/或货架期延长中的作用及其添加剂优势。在清洁氢气存在下,以水溶性N,N,N-三甲基壳聚糖为稳定剂,对锌盐进行绿色还原,合成了NTMC-ZnONPs。紫外-可见光谱测量表明,NTMC-ZnONPs在360 nm处表现出强烈的表面等离子体共振,这与ZnONPs相同。对NTMC-ZnONPs的详细表征证实了ZnONPs的形成,其平均粒径为37.6 nm。此外,不同浓度的NTMC-ZnONPs将未受损的番茄果实浸泡在NTMC-ZnONPs溶液中60 s,然后在塑料容器中储存。采集ntmc - znonps处理后番茄果实的理化品质参数数据,即:颜色、总悬浮固体(TSS)、维生素C、番茄红素、pH、β-胡萝卜素、保质期和硬度。研究发现,NTMC-ZnONPs显著改善了番茄果实的硬度、颜色、β-胡萝卜素含量、保质期和味道,而TSS随着成熟的进展而增加。因此,本研究确定了绿色NTMC-ZnONPs在贮藏过程中涂覆NTMC-ZnONPs提高果实品质的适用性和适宜性。
