  公开（公告）日：1980-09-17

  Polyamino acids having a degree of polymerization of from 3 to about 60 have been found to be waterinso- luble yet digestible in the presence of certain common proteolytic enzymes. Unlike the higher molecular weight polyamino acids, the polyamino acid products of this invention are useful for nutritional fortification of food materials.

  研究发现，聚合度在 3 到 60 之间的聚氨基酸具有水溶性，但在某些常见的蛋白水解酶的作用下可以被消化。与分子量较高的聚氨基酸不同，本发明的聚氨基酸产品可用于食品材料的营养强化。
