Foreword

This standard replaces GB 3150-1999 "food additive sulfur." The main technical differences between standard and GB 3150-1999 are as follows. - Added sulfide indicators and test methods; - Increases the weight determination of organic content; - Added diethyl dithiocarbamate silver spectrophotometric determination of arsenic content. Appendix A of this standard is a normative appendix. This standard replaces the standards previously issued as follows. --GB/T 3150-1982, GB/T 3150-1999. National Food Safety Standard Food additives sulfur

1 Scope
