Evaluation of Uncertainty in Measurement of Formaldehyde Content in Waterishlogged Food Products by Spectrophotometer
Abstract：Formaldehyde content in waterishlogged food products (water risen sea cucumber) was measured by using spectrophotometer, and the various factors affecting measurement were analyzed and assessed. Then the mathemati- cal model of uncertainty was established to systematically calculate the uncertainty of each components and the un- certainty of the influencing factors. The results showed that the main factors affecting formaldehyde content meas- urement in waterishlogged food products were the repetitive operating process in test, the accuracy of the standard operating fluid and the accuracy of the concentration of distillate.
