近几年来,世界许多国家和地区研制开发可以被人体消化吸收的可食性包装材料,对控制白色污染具有广阔前景。 美国农业部农业研究局南部地区研究中心,利用大豆提炼的蛋白质,制造成功类似塑料的化合物,作为新一代食品包装材料,替代过去以石油为原料合成的塑料。其制作技术是:将大豆用水浸泡,软化之后加工磨碎,使蛋白质从固体成分中分离出来,而后将其晾干浓缩;另一种是用机械除去其中的水 In recent years, many countries and regions in the world have researched and developed edible packaging materials that can be digested and absorbed by the human body, and have broad prospects for the control of white pollution. The U.S. Department of Agriculture’s Southern Research Center for Agricultural Research, using soybean-derived proteins, has successfully manufactured plastic-like compounds as a new generation of food packaging materials, replacing plastics that were previously synthesized from petroleum. Its production techniques are: soak soybeans with water, soften and grind them, separate proteins from solids, and then dry them by air; the other method is to mechanically remove the water.
