Foreword
This standard replaces GB 25580-2010 "national food safety standards for food additives stable chlorine dioxide solution."
This standard compared with GB 25580-2010, the main changes are as follows.
--- Standard name was changed to "national food safety standards for food additives stable chlorine dioxide";
--- Modify the chlorine dioxide content index requirements and test methods;
--- Modify the pH indicator;
--- Remove the methanol index.
