Evaluation of Uncertainty for the Improvement Method of Peroxide Value in the Oil Extracted from Silkworm Pupa

ZHENG Chen,CHEN Jun,ZHENG Li(Suzhou Entry-Exit Inspection and Quarantine Bureau,Suzhou 657000,China)  
Oil extraction in the silkworm pupa is improved with impregnation method,and peroxide value of uncertainty is studied.Through establishment of mathematical model in the measurement process,the sources of uncertainty are calculated and assessed with the method of high-reliability synthetic standard difference.As a result,with this method,the uncertainty and expanded uncertainty for the determination of peroxide value in silkworm pupa with impregnation method is 0.172±0.0069.
