外界条件对黄酒挥发酯测定的影响

Effects of External Conditions on the Determination of Volatile Esters Content in Yellow Rice Wine

黄酒中挥发酯含量的测定是评价黄酒质量的一项较重要的理化指标,也是一项不易准确检测的分析项目。采用电位滴定法测定黄酒中的挥发酯,一定要严格遵守容量分析的操作规程,精心校正分析仪器,正确、细致操作,减少操作误差,并注意控制好外界条件,防止酯类挥发。(陶然)

Volatile esters content in yellow rice wine was an important index to assess wine quality and also an analytic item hard for accurate measurement. The following rules should be highly valued and strictly followed during the use of potentiometric titration in the measurement of volatile esters content： follow the relative operation rules of volumetric analysis strictly, make correction for analytic apparatus before measurement, appropriate and careful operation to minimize errors, and proper control of external conditions to prevent ester evaporation.
