Abstract

The aim of this work was to produce chitosan based films which can be used as an effective packaging material. In order to produce a material like that chitosan was extracted from the crab shells by the process of demineralization, deproteinization and deacteylation and the obtained chitosan was made into a film with additives like Turmeric/ Clove/Ginger and gelatin. Plasticizer like glycerol was also added to obtain a transparent, stretchable, exquisite film which is a active packaging material and the film forming solution was used as a coating over the areca nut plates and cups to prevent the microbial spoilage and to increase the shelf life of them and then coating was also performed on fruits and vegetables to prevent spoilage and increase their shelf life. The film was checked for its thickness, transparency and stability. The physical, chemical and biological parameters were evaluated by performing the characterization studies like SEM, TG-DSC, TG-DTG, DSC and FTIR. The antioxidant, anticoagulant properties and cytotoxicity were tested to analyse and evaluate the quality of the film. The results state that the film has good thermal stability and through the results of FTIR it is proved that the film has functional groups of chitosan, gelatin, turmeric and other added components. And other results proved that the film is completely safe to be used as a food packaging material. Concerning/pertaining to the environmental issues and the effects of plastic films in human in terms of health and degradability conditions chitosan based films can bring about a change in the current packaging industry and the change could lead to better human and environmental health.
壳聚糖与姜黄/丁香/姜精油复合薄膜用于食品包装
本工作的目的是制备壳聚糖基薄膜,作为一种有效的包装材料。为了生产出这样一种材料,我们从蟹壳中提取壳聚糖,通过脱矿、脱蛋白、脱乙酰等过程,将壳聚糖与姜黄、丁香、姜、明胶等添加剂一起制成薄膜。加入甘油等增塑剂,得到透明、可拉伸、细腻的薄膜,这是一种有效的包装材料,将成膜液涂在槟榔板和杯上,防止微生物变质,延长其保质期,然后对水果和蔬菜进行涂膜,防止变质,延长其保质期。检查了薄膜的厚度、透明度和稳定性。通过SEM、TG-DSC、TG-DTG、DSC和FTIR等表征研究,对其物理、化学和生物学参数进行了评价。通过抗氧化、抗凝血和细胞毒性测试来分析和评价膜的质量。结果表明,该膜具有良好的热稳定性,并通过红外光谱结果证明该膜具有壳聚糖、明胶、姜黄等添加组分的官能团。等实验结果证明该薄膜作为食品包装材料是完全安全的。关于环境问题和塑料薄膜在人体健康和降解条件方面的影响,壳聚糖基薄膜可以引起当前包装工业的变化,这种变化可以导致更好的人类和环境健康。
