魔芋葡甘聚糖是日用化学工业潜在的廉价原料之一。以魔芋葡甘聚糖为原料 ,分别加入卡拉胶、卡拉胶和黄原胶、黄原胶等其它高分子多糖后进行复配。利用红外光谱法对魔芋葡甘聚糖及复配产物的成膜机理进行了探讨 ,并对膜的性能进行了分析研究 ,提出了制膜方法。文中成膜速度控制容易 ,制作方法简便 ,这为开发多种具有凝胶成膜性的日用化学产品提供了依据。 Konjac glucomannan is one of the potential cheap ingredients for the daily chemical industry. Konjac glucomannan as raw material, were added carrageenan, carrageenan and xanthan gum, xanthan gum and other polymer polysaccharides after the complex. The film forming mechanism of konjac glucomannan and its complex product was studied by using infrared spectroscopy. The performance of the film was analyzed and the film forming method was proposed. In this paper, the film formation speed control is easy, and the production method is simple, which provides the basis for developing a variety of daily chemical products with gel filming property.
