摘要

为了获得更好的秋葵保鲜效果,本研究对壳聚糖(CS) -纳米晶纤维素(NCC)复合涂层作为秋葵保鲜剂进行了研究。采用CS、NCC、CS-纤维素复合(CS-CC)和CS:CC: 2:1 (2CS-CC) 4种处理,得到了3种不同的秋葵果实(水果果、奈油果和芙蓉果)。在储存过程中,定期测定水果的失重率、腐烂率和质地特征(如硬度、弹性、黏性、粘性、咀嚼性和弹性)。结果表明,CS-NCC复合涂层不能降低果实失重速率。只有2CS-CC处理抑制了芙蓉的果腐率(C)。然而,与CS处理(1%)相比,NCC处理没有明显的改善。CS-CC处理有利于保持秋葵果实在贮藏过程中的质地参数。果实质地参数的变化具有明显的品种依赖性。

Chitosan-nanocrystal cellulose composite coating could inhibit fruit decay rate and maintain the texture parameters of fruit in okra (Abelmoschus esculentus [L.] Moench)
In order to obtain a better preservation effect on okra fruit, this study examined chitosan (CS)–nanocrystal cellulose (NCC) composite coating as a preservative agent. Four treatments, including CS, NCC, CS–cellulose composite (CS-CC), and ratio of CS:CC: 2:1 (2CS-CC), were implemented to create three different okra fruits (Shuiguo, Naiyou, and Hibiscus coccineus). Rate of weight loss, decay rate, and texture profiles (e.g., hardness, springiness, cohesiveness, gumminess, chewiness, and resilience) of the fruits were determined regularly during storage. Our results showed that a CS-NCC composite coating could not reduce rate of weight loss of the fruits. Only 2CS-CC treatment inhibited the fruit decay rate in Hibiscus coccineus (C). Nevertheless, NCC treatment did not result in a distinct improvement compared with CS treatment (1%). CS-CC treatment could be advantageous for maintaining the texture parameters of okra fruit during storage. Notably, change in the fruit texture parameters presents a significant cultivar-dependent pattern.
