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 3263-1982 "Food Additives gallic acid ester."
This major change compared to the standard GB 3263-1982 as follows.
--- cancel the original standard limits of heavy metals;
--- physical and chemical indicators increased the limit of lead.
This standard is proposed and managed by the National Standardization Technical Committee on Food Additives.
Drafted by. China Food Fermentation Industry Research Institute, Zhangjiajie trade sources Chemical Co., Ltd.

5 Test methods
Unless otherwise stated, use only confirmed in the analysis of analytical grade reagents and GB/T 6682 stipulated water. Standard used in the analysis
Titration solution, standard solution, the determination of impurities, products and preparations, in the absence of other requirements specified, are by GB/T 601, GB/T 602,
GB/T 603 Preparation predetermined. When present in the standard solution which is formulated with a solvent not specified, refer to an aqueous solution.
5.1 sensory testing
Proper amount of sample is placed in a clean, dry porcelain dish, under natural light, its appearance was observed.
5.2 Identification of
5.2.1 Reagents and solutions
a) ferric chloride solution. mass fraction of 1%;
b) ethanol solution. volume fraction of 75%;
c) Sodium hydroxide solution. 1mol/L.
5.2.2 Operation
5.2.2.1 About 0.5g sample was dissolved in 10mL1mol/L sodium hydroxide solution, distilled, the distillate take approximately 4 mL, which was to be clarified,
There propanol odor when heated.
5.2.2.2 Approximately 0.1g sample was dissolved in 5mL75% ethanol solution, add 1 drop of 1% ferric chloride solution, it was purple.
5.3 Content
5.3.1 Reagents and solutions
a) bismuth nitrate solution. Weigh 5g of bismuth nitrate [Bi (NO3) 3 · 5H2O], placed in an Erlenmeyer flask, were added 7.5mL of nitric acid and 10mL
Water, shaken vigorously and dissolved, cooled, filtered, diluted with water to 250 mL volume, backup.
