摘　　要：采用碱性蛋白酶脱除天然胶乳中的蛋白质的生物化学方法 ,研究稳定剂和酶的用量及其制备工艺条件等对脱蛋白效果的影响。与普通离心浓缩胶乳对照 ,研究了脱蛋白天然胶乳 (DP -NRL)的有关力学性能。在 37℃连续搅拌 2 0h条件下 ,碱性蛋白酶和稳定剂SDS的用量分别为 0 .0 3 %、0 .2 5 %时可以获得较佳的脱蛋白效果。The bio chemical method that alkali proteinase was used to remove the protein in NR latex,the influences of the amount of stabilizer and enzyme and its technical condition on deprotein effect have been investigated.Contrast with common centrifugal condensed NR latex,the mechanical properties of the deproteinized NR latex have been studied.Better deprotein effect has been obtained when the amount of alkali proteinase and stabilizer(sodium dodecyl sulphate,SDS) was 0.03%,0.25% respectively at 37℃ for 20h.
