Foreword
Chapter 4 of this standard is mandatory, the rest are recommended.
This standard is used by the US to modify "Food Chemical Codex" (FOODCHEMICALSCODEX) (fifth edition) specifications.
The main difference between this standard and the US "Food Chemical Codex" (fifth edition) technical specifications are. increasing the limit of arsenic.
Instead of the standard GB 8273-1987 "D- sodium erythorbate food additive."
This major change compared to the standard GB 8273-1987 as follows.
--- increased identification test;
--- canceled the physical and chemical indicators of clarity and heavy metals index;
--- physical and chemical indicators increased the loss on drying and lead indicators.
This standard is proposed and managed by the National Standardization Technical Committee on Food Additives.
This standard is mainly drafted by. Dexing City Barbican different VC sodium Co., Ltd., Zhengzhou top Yang Industrial Co., Ltd., China Food Fermentation Industry
Research Institute.
The main drafters. Zhou Qiang, Wang Jingchen, Li Huiyi, Lin Yu Si, Su Xiao shading, firewood Qiuer.
This standard supersedes the previous editions are.
