预处理对再生蛋白纤维蛋白质含量测定的影响

Influence of pretreatment on the protein content detection in regenerated protein fiber

为了探讨预处理对再生蛋白纤维中蛋白质含量测定的影响,将再生蛋白纤维(大豆蛋白复合纤维和蚕蛹蛋白粘胶纤维)试样分为两份,其中一份进行预处理。两份样品均采用凯氏定氮法测试蛋白质含量,将所得的两组数据利用SPSS软件进行t检验。结果表明,预处理对大豆蛋白复合纤维中蛋白质含量的测定无显著影响,对蚕蛹蛋白粘胶纤维中蛋白质含量的测定有较大影响,导致测试结果偏低。

In order to analyze the influence of pretreatment on determination of protein content in regenerated protein fiber,the regenerated protein fiber(soybean protein composite fiber and silkworm pupa protein viscose fiber) is divided into two parts and one of them is pretreated. The protein content of both samples are tested by Kjeldahl method,then two sets of data are analyzed by t-test with the help of SPSS software. The results show that pretreatment have no significant effect on the protein content detection in soybean protein composite fiber,and have great effect on the protein content detection in silkworm pupa protein viscose fiber with low test result.
