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. The main drafters. Lihui Yi, Tang Xian-red, wood Qiuer, Chen Xueyong, soup Hz. This standard supersedes the previous editions are. --- GB 3263-1982. Food Additives gallic acid ester Range 1 This standard specifies the food additive gallic acid propyl technical requirements, test methods, inspection rules, marking, packaging, transportation, storage and Shelf life. This standard applies to gallic acid and n-propanol at an acidic dehydrating agent, heating the obtained esterifying gallic acid ester.2 Normative referencesTerms of the following documents become provisions of this standard by reference in this standard.

Technical Requirements 4.1 Sensory requirements White or milky white crystalline powder. 4.2 Physical and Chemical Indicators Shall comply with the requirements in Table 1. Table 1 Physical and Chemical Indicators Item Index Content (in terms C10H12O5)/98.0 to 102.0% Melting point/℃ 146 ~ 150 Arsenic (As)/(mg/kg) ≤ 3 Lead (Pb)/(mg/kg) ≤ 1 Loss on drying /% ≤ 0.5 Residue on ignition /% ≤ 0.15 Test methodsUnless 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.
