| 摘 要： | 酪蛋白磷酸肽简称ＣＰＰｓ（Ｃａｓｅｉｎ ｐｈｏｓｐｈｏｐｅｐｔｉｄｅｓ），是一种具有多种生物活性的多肽。国外已经对其制备方法进行了大量研究，但是目前用于工业化生产必定增加成本，本项研究改用价格十分谦价的２７０９碱性蛋白酶水解酪蛋白得到了和胰蛋白酶水解酪蛋白同样的产品，实验结果表明利用２７０９碱性蛋白酶水解酪蛋白帛备ＣＰＰｓ可以大大降低成本。

| Abstract: | CPPs (Casein phosphopeptides)are mulitibioactive peptides. There are many research works done in many countries for CPPs preparation, but up to now, what was used to produce CPPs in large scale was trypsin.However, it is known that trypsine was very expensive. So in this paper, a much more cheaper proteasae, alkaline protease 2709 was found to be suitable for CPPs preparation in large scale. |
