    • The present invention relates to water-soluble natural film and its preparing method. More particularly, the present invention relates to water-soluble natural film manufactured by dissolving as an active ingredient a water-soluble chitosan prepared in such a manner that chitin/chitosan decomposed with lysozyme is rinsed with ethanol, subjected to electric adjustment and sonication in a saline solution and to ion-exchange to obtain water-soluble β-glucosamine fibrin followed by nano-sized coating the β-glucosamine fibrin with immunoglobulin (γ-globulin), and seaweeds and functional ingredients in distilled water and gelatinating. The water-soluble natural film according to the present invention, unlike the conventional film containing chitosan, comprises, at a predetermined content ratio, chitosan with improved water solubility and immunity, seaweeds and functional ingredients. Therefore, it imparts elasticity to matrix of a film to enable film molding with convenience and renders more compatibility to human body due to natural materials as its active ingredients, eliciting more favorable feeling when taken in. In particular, the film composition itself is processed to form a film with a desired thickness and size or is coated on a conventional biodegradable resin film, being applicable to a film in preparing an oral cleaning agent with immediate effect and a food packaging material.
    • 本发明涉及水溶性天然膜及其制备方法。 更具体地说,本发明涉及通过将以溶菌酶分解的壳多糖/壳聚糖用乙醇冲洗的水溶性壳聚糖作为活性成分溶解而制造的水溶性天然膜,用乙醇冲洗,进行电调节和超声处理 盐水溶液和离子交换以获得水溶性β-葡糖胺纤维蛋白,然后用免疫球蛋白(γ-球蛋白)纳米尺寸涂布β-葡糖胺纤维蛋白,并将海藻和功能成分在蒸馏水中凝胶化。 根据本发明的水溶性天然膜与常规含有壳聚糖的膜不同,含有预定含量的具有改善的水溶性和免疫性,海藻和功能成分的壳聚糖。 因此,由于天然材料作为活性成分,因此赋予膜的基质赋予弹性,能够方便地进行成膜,并且由于天然材料的活性成分而使人体更容易相容,因此在摄取时引起更好的感觉。特别地,将膜组合物本身加工成 形成具有所需厚度和尺寸的膜,或涂覆在常规的可生物降解树脂膜上,适用于制备立即口服清洁剂的膜和食品包装材料。
