Abstract

The present investigation utilizes the eco-efficient pullulan polysaccharide as film forming biopolymer. Pullulan-based edible films offer good physical, thermal and mechanical properties which enable them to use in shelf-life preservation of fresh produce. Blends of other film forming polysaccharides, plasticizers and an antioxidant with pullulan (Pu) solution were prepared in order to determine physical and optical parameters of those films. The morphological and biodegradable studies were attempted to identify the changes on the films’ surfaces. The films made from (only) pullulan (10Pu), pullulan composited with sodium alginate(10Pu_0.5SA), gelatin (10Pu_0.5G), polyethylene glycol (10Pu_0.5PG), calcium chloride and lemon juice (10Pu_1CC_2L) resulted heavier film densities, higher whiteness indexes and lower total color difference values.All the films were tested for their biodegradability in soil, where visual changes were appreciated after 15 days, partial and complete degradation took place at the end of 34 days and 53 days, respectively. Thus, these pullulan blended films could be a better replacement for synthetic films towards environmental problems.

普鲁兰/增塑剂共混膜的配方及其物理和生物降解性研究

本研究利用生态高效的普鲁兰多糖作为成膜生物聚合物。普鲁兰可食用薄膜具有良好的物理、热、机械性能，可用于保鲜保鲜。制备了其他成膜多糖、增塑剂和抗氧化剂与普鲁兰(Pu)溶液共混，以测定这些成膜的物理和光学参数。形态学和可生物降解的研究试图确定膜表面的变化。由(纯)普鲁兰(10Pu)、与海藻酸钠(10Pu_0.5SA)、明胶(10Pu_0.5G)、聚乙二醇(10Pu_0.5PG)、氯化钙和柠檬汁(10Pu_1CC_2L)复合制成的普鲁兰薄膜密度更大，白度指标更高，总色差值更低。所有膜在土壤中的生物降解性测试，15 d后观察到视觉变化，34 d和53 d分别发生部分和完全降解。因此，这些普鲁兰混合膜可以更好地替代合成膜来解决环境问题。

期刊介绍： The Association of Biotechnology and Pharmacy (ABAP) will be useful to form a forum for scientists so that they can bring together to discuss and find scientific solutions to the problems of society. The annual meetings will help the members to share their knowledge and publish their research knowledge particularly by members and fellows of the Association and special care will be taken to provide an opportunity for young scientists. Besides this the association is planned to organize symposia, seminars and workshops on current developments of Biotechnology and Pharmacy particularly on the subject of current scientific interest, and the proceedings of which will be published regularly. And in view of the vast development of science and to disseminate the problems in publication of research work, an international journal of Current Trends in Biotechnology and Pharmacy has been started by ABAP.
