Abstract

The effect of irradiated chitosan coating on post-harvest preservation of tomato was observed in this study. Irradiated chitosan (40 kGy) solution of various concentrations (500, 750, 1000, 1500 and 2000 ppm) were applied on post-harvest preservation of tomato. Both chitosan treated and untreated (control) tomato were stored at room temperature in open and zip bag conditions. The effect of coating of various chitosan solutions on tomato were observed during storage period. The percentage of weight loss and spoilage rate of the preserved and control tomato samples were investigated. Several parameters (such as total bacteria count, total mold count, moisture, ash, acidity, vitamin C, sugar, protein and fat) were analyzed for irradiated chitosan coated tomato in open condition after 3-weeks storage period. In addition, the same parameters were also analyzed for control tomato. Considering all parameters, the results revealed that 1500 ppm chitosan solution performed better in extending the shelf- life of tomato as compared to the control and other treated samples. Thus, this observation recommend that irradiated chitosan coating have the potential to be used as natural preservative to maintain quality and extending shelf-life of tomato.

辐照壳聚糖对番茄保鲜期的影响及其理化特性研究

本研究观察了辐照壳聚糖涂层对番茄采后保鲜的影响。将不同浓度（500、750、1000、1500和2000ppm）的辐照壳聚糖（40kGy）溶液应用于番茄采后保鲜。壳聚糖处理的和未处理的（对照）番茄都在室温下在打开和拉链袋的条件下储存。观察了不同壳聚糖溶液在番茄贮藏过程中的包衣效果。研究了保存番茄和对照番茄样品的失重率和腐败率。对辐照壳聚糖包衣番茄在开放条件下贮藏3周后的几个参数（如细菌总数、霉菌总数、水分、灰分、酸度、维生素C、糖、蛋白质和脂肪）进行了分析。此外，还对对照番茄的相同参数进行了分析。综合考虑所有参数，结果表明，与对照和其他处理样品相比，1500ppm壳聚糖溶液在延长番茄货架期方面表现更好。因此，这一观察结果表明，辐照的壳聚糖涂层有潜力用作天然防腐剂，以保持番茄的质量并延长其保质期。
