Foreword

This standard replaces GB 8317-2006 "food additive ethyl lactate." This standard compared with GB 8317-2006, the main changes are as follows. --- Ethyl lactate content was measured by packed column gas chromatography to capillary gas chromatography; --- Delete the words "heavy metal content" and "Arsenic content" requirement. National Food Safety Standard Food additive ethyl lactate
