摘要

Preparation of hyperdeproteinized natural rubber was made from fresh latex and preserved high-ammonia latex by treatment with urea in the presence of sodium dodecyl sulfate. Concentration of urea, temperature, and time for the incubation were investigated to remove the proteins effectively. Under the best conditions, the total nitrogen content and amount of allergenic proteins for the deproteinized rubbers were 0.005 wt % and 1.0 mug/ml, respectively, which were less than those of natural rubber deproteinized with proteolytic enzyme. The hyper-deproteinized natural rubber was proved through FT IR spectroscopy. (C) 2004 Wiley Periodicals, Inc.
