Foreword
This standard was drafted in accordance with the rules of GB/T 1.1-2009 and GB/T 20001.4-2001 given.
This standard replaces YC/T 216-2007 "Determination of tobacco and tobacco products, starch continuous flow method", and YC/T 216-2007
Compared to the main technical changes are as follows.
--- Increased G3 sintered glass frit funnel, so that the starch extraction and removal of interfering substances completed within the apparatus;
--- Using ultrasonic water bath at 80 ℃ 30min 30min replace tobacco sample to remove interfering substances;
--- Using ultrasonic extraction 10min 10min tobacco alternative to stand starch.
