Method for increasing gelatin transparency

The present invention relates to a method for raising transparency of gelatin, and it is mainly characterized by that a clarification procedure is added before concentration, said procedure utilizes polyacrylamide as flocculant, uses active white clay as adsorbing agent, and adds them into gelatin solution, and adopts the processes of stirring at a certain temp. and standing still for a period oftime, so that it can make the impurities being gelatin solution be separated out from the gelatin solution to attain the goal of raising transparency of gelatin. 本发明涉及一种提高明胶透明度的方法，其主要特征是在浓缩前增加了一道澄清工序。在该工序中利用聚丙烯酰胺作为絮凝剂，活性白土作为吸附剂加到明胶溶液中，在一定温度下搅拌，然后静置一段时间。这时，明胶溶液中的杂质在絮凝剂的作用下与吸附剂结成致密的整体状大块絮团沉淀或漂浮，彻底与明胶溶液分离。其结果得到是色泽浅、透明度高的明胶，从根本上解决了明胶的透明问题。特别是对提高最后一、二道胶的透明度效果十分显著，具有明显的经济效益。
