Foreword

Chapter 4 of this standard are mandatory, the rest are recommended. The revised standard used by the US "Food Chemical Codex" (FOODCHEMICALSCODEX, fifth edition) specifications. The main differences between the standard and the United States, "Food Chemical Codex" (fifth edition) of the technical specifications are as follows. increase of arsenic and lead limit requirements. This standard replaces GB 1916-1980 "food additive tert-butyl-4-hydroxy anisole." This standard and GB 1916-1980 major technical changes are as follows. --- Physical and chemical indicators increased content indicators; --- Physical and chemical indicators to remove heavy metals projects, increasing the lead limit requirements. Appendix A of this standard is a normative appendix. This standard by the National Standardization Technical Committee on Food Additives and centralized. This standard is mainly drafted by. Danisco (China) Co., Ltd., China Food Fermentation Industry Research Institute. The main drafters of this standard. Yan Sumin, Li Huiyi, firewood Qiuer, Wen Yan. This standard replaces the standards previously issued as follows. --- GB 1916-1980. Food additives tert-butyl-4-hydroxy-anisole
