Foreword

This standard replaces GB 12487-2004 "food additives ethyl maltol." This standard compared with GB 12487-2004, the main changes are as follows. - Canceled the project lead and the corresponding test methods; - Ethyl maltol content index is modified by ≥ 99.2% ≥ 99.5% (dry basis), the arsenic index ≤ 2 mg/kg modification To ≤ 1 mg/kg. The Standard Annexes A and B are normative appendix. This standard replaces the standards previously issued as follows. --GB 12487-1990, GB 12487-2004. National Food Safety Standard Food additives ethyl maltol

1 Scope

This standard applies to furfural produced by chemical synthesis of food additives ethyl maltol.
