Foreword

This standard replaces GB 4578-2008 "food additive sodium saccharin." This standard compared with GB 4578-2008, the main changes are as follows. --- Standard name was changed to "national food safety standards for food additives, saccharin sodium." National Food Safety Standard Sodium Saccharin Food Additive

1 Scope

This standard applies to phthalic anhydride as raw materials by chemical synthesis prepared food additive sodium saccharin. 2 molecular formula, relative molecular mass and structural formula Formula 2.1 C7H4NNaO3S · 2H2O 2.2 formula 2.3 relative molecular mass 241.20 (according to 2007 international relative atomic mass)

Appendix A

Testing method A.1 Safety Tips Reagents The standard test methods used for toxic or corrosive, the operation should take appropriate safety and health practices. A.2 General Provisions This standard reagents and water in the absence of other specified requirements, refer to the three water analytical reagent and GB/T 6682 regulations. Reagent The standard solution, standard solution for measuring impurities, formulations and products, did not indicate when the other requirements according to GB/T 601, GB/T 602, GB/T 603 provisions of the preparation. Solution was used in the tests did not indicate what is formulated with solvent, it refers to an aqueous solution. A.3 Identification Test A.3.1 Reagents and materials A.3.1.1 resorcinol. A.3.1.2 sulfuric acid. A.3.1.3 sodium hydroxide solution. 40g/L. A.3.1.4 hydrochloric acid solution. 19. A.3.2 Analysis step A.3.2.1 Take a sample of about 20mg, about 40mg plus resorcinol, and the mixture after adding 10 drops of sulfuric acid, heating with Weihuo to significant dark green, cool, Add 10mL water and 10mL of sodium hydroxide solution, Serve green fluorescent solution. A.3.2.2 take platinum wire, with hydrochloric acid solution after wet, dipped into the sample, in a colorless combustion flame, the flame that was bright yellow. A.3.3 melting point determination The method according to GB/T 617 predetermined measurement. Take a sample of about 0.3g, add 5mL dissolved in water, dilute hydrochloric acid was added 1mL that crystallize, Filtered, residue washed with water and dried to 105 ℃ ± 2 ℃ measured melting point should be 226 ℃ ~ 230 ℃. A.3.4 solubility Soluble in water, slightly soluble in ethanol. A.4 Determination of saccharin sodium content A.4.1 Reagents and materials A.4.1.1 glacial acetic acid. A.4.1.2 acetic anhydride. A.4.1.3 crystal violet indicator solution. 5g/L. A.4.1.4 perchloric acid standard titration solution. c (HClO4) = 0.1mol/L. A.4.2 Analysis step Weigh the sample after drying of about 0.3g, accurate to 0.0002g, was added 5mL 20mL glacial acetic acid and acetic anhydride, dissolved, add 2 drops Crystal violet indicator solution, titration with perchloric acid standard solution titration until the solution was blue-green. A.4.3 Calculation Results Saccharin sodium content mass fraction w1, according to equation (A.1) Calculated. w1 = V × M m × 100% (A.1) Where. Volume V --- perchloric acid standard titration solution consumed in milliliters (mL); M --- 1mL0.1mol/L perchloric acid standard titration solution equivalent 0.02052g saccharin (C7H4NNaO3S); M --- the quality of the sample, in grams (g). Take two parallel determination results of the arithmetic average of the measurement results, the absolute difference between the parallel determination results shall not exceed the arithmetic mean 0.2%. A.5 acidity and alkalinity test A.5.1 Reagents and materials A.5.1.1 sodium hydroxide standard titration solution. c (NaOH) = 0.1mol/L. A.5.1.2 phenolphthalein indicator solution. 10g/L. A.5.2 Analysis step Weigh 1.0g sample was dissolved in 10mL freshly boiled and cooled water. Add 1 drop of phenolphthalein indicator solution, the solution should be no pink color; plus 1 drop of sodium hydroxide solution, the solution should appear pink. A.6 benzoate and salicylate test A.6.1 Reagents and materials A.6.1.1 acetic acid. A.6.1.2 ferric chloride test solution. Weigh 9g of ferric chloride (FeCl3 · 6H2O), dissolved in water and dilute to 100mL. A.6.2 Analysis step Weigh 0.5g sample was dissolved in 10mL water, add 5 drops of acetic acid, plus 3 drops of ferric chloride solution, there should be no precipitate or violet appears. 5102- 81􀏕 6881
