Foreword

This standard replaces GB 1886.40-2015 "National Food Safety Standard for Food Additives L-Malic Acid". Compared with GB 1886.40-2015, the main changes in this standard are as follows. ---The scope has been changed; ---Added physicochemical indicators. moisture and succinic acid; ---The descriptions of physicochemical indicators, total arsenic content, and total arsenic limits have been revised, and heavy metals have been removed; ---The testing methods for identification, content, clarity, fumaric acid, maleic acid, lead, and total arsenic have been revised; ---A test method for succinic acid has been added; ---Appendices A and B have been revised, and Appendix C has been added. National Food Safety Standards L-malic acid, a food additive 1.Scope This standard applies to L-malic acid, a food additive produced by enzyme engineering from fumaric acid or fumarate; or from starch. L-malic acid is a food additive produced by fermentation using sugars as raw materials. 2.Chemical name, molecular formula, structural formula, and relative molecular mass 2.1 Chemical Name L-hydroxysuccinic acid 2.2 Molecular Formula C4H6O5 2.3 Structural Formula 2.4 Relative Molecular Mass 134.09 (based on 2022 international relative atomic mass)

Appendix A

Test methods A.1 Warning Some test procedures specified in the test methods may lead to hazardous situations. Operators should take appropriate safety and health precautions. A.2 General Provisions Unless otherwise specified, all reagents used in this standard refer to analytical grade reagents. Standard titration solutions and impurity determination solutions used in the experiments... Unless otherwise specified, solutions, preparations, and products shall be prepared in accordance with the provisions of GB/T 601, GB/T 602, and GB/T 603.Tests Unless otherwise specified, the solutions used in this article refer to Grade III water as defined in GB/T 6682. A.3 Identification Test A.3.1 Reagents and Materials A.3.1.1 Ammonia solution. Ammonia water = 2 3. A.3.1.2 p-Aminobenzenesulfonic acid solution. 10 g/L. A.3.1.3 Sodium nitrite solution..200g/L. A.3.1.4 Sodium hydroxide solution. 40 g/L. A.3.2 Analysis Steps A.3.2.1 Identification by colorimetric reactions of ammonium salts Weigh 0.5g of the sample, accurate to 0.01g, and place it in a 50mL test tube. Add 10mL of water to dissolve. Neutralize to neutral with ammonia solution. Add 1 mL of p-aminobenzenesulfonic acid solution and heat in a boiling water bath for 5 minutes. Add 5 mL of sodium nitrite solution and heat in a boiling water bath. After 3 minutes, add 5 mL of sodium hydroxide solution and observe from top to bottom; it should immediately turn red. A.3.2.2 Identification by Infrared Absorption Spectroscopy In accordance with GB/T 6040, the potassium bromide pellet method was used for qualitative analysis, and the infrared absorption spectrum was determined. The infrared absorption spectrum of the sample should be consistent with... Appendix B is basically the same. A.4 Determination of content (calculated as C4H6O5) A.4.1 Method Summary Using phenolphthalein as an indicator, the sample solution is titrated with a standard sodium hydroxide solution. The amount of sodium hydroxide solution consumed is calculated based on the total amount of sodium hydroxide solution used. Calculate the total acid concentration in the sample solution (as C4H6O5). A.4.2 Reagents and Materials A.4.2.1 Standard titration solution of sodium hydroxide. c(NaOH) = 0.5 mol/L. A.4.2.2 Phenolphthalein indicator solution. 10 g/L. A.4.3 Instruments and Equipment Analytical balance. sensitivity is 0.0001g. ......
