铬革屑酶法提取胶原蛋白交联反应制备高分子量产物Ⅰ.明胶的提取(续)

摘要：

@@ Results and DiscussionThe composition of chrome shavings, a byproduct of leather production, will vary from batch to batch since there is variation in both the hides and the tanning processes employed. Analysis of shavings from several commercial sources yielded the following relatively narrow ranges of values for pH (3 to 4), moisture (50% to 54%), ash (8% to 14%), TKN (14% to 16%), fat (0. 1% to 1.8%)and chromium (3% to 4% as chromic oxide). If the pH is outside of this range, it would have to be adjusted to assure the success of the process; other values used to characterize the shavings are not critical.
