Abstract

The experiment was aimed to investigate the effect of different concentrations of chitosan on shelf life and quality of banana fruit. The single factor experiments were laid out in a completely randomized design with three replications. Experimental treatments included Control, 0.50%, 0.75%, 1.0%, 1.5%, 2.0% chitosan. Sabri Banana cultivar is one of the most popular commercial cultivars of banana in Bangladesh. Chitosan treatment caused highly significant variation in respect of the physico-chemical parameters such as color changes, firmness, weight loss, disease severity and shelf life of banana during storage. Considering the effects of different concentrations of chitosan, 0.75% and 2.0% chitosan were found to be the best in respect of all the parameters investigated. Fruits treated with the above concentrations of chitosan, had the longest shelf life (9 days), whereas fruits under control had the shortest shelf life (8 days). The application of chitosan treatment in fresh crops is safe for consumers and for the environment. It can be used to improve postharvest quality and to extend shelf life of banana.
不同浓度壳聚糖对香蕉果实保质期和品质的影响
本试验旨在研究不同浓度壳聚糖对香蕉果实保质期和品质的影响。单因素试验采用完全随机设计,重复3次。试验处理为对照、0.50%、0.75%、1.0%、1.5%、2.0%壳聚糖。Sabri香蕉品种是孟加拉国最受欢迎的商业香蕉品种之一。壳聚糖处理对香蕉贮藏过程中色泽变化、硬度、失重、疾病严重程度和保质期等理化参数产生了极显著的影响。考虑不同浓度壳聚糖的影响,以0.75%和2.0%壳聚糖为最佳。经上述浓度壳聚糖处理的水果保质期最长(9天),而未经处理的水果保质期最短(8天)。壳聚糖处理在新鲜作物中的应用对消费者和环境都是安全的。它可以提高香蕉采后品质,延长香蕉的货架期。
