Foreword

This standard replaces GB 5009.225-2016 "National Food Safety Standard Determination of Ethanol Concentration in Wine". Compared with GB 5009.225-2016, the main changes in this standard are as follows. ---The name of the standard is modified to "National Food Safety Standard Determination of Ethanol Concentration in Wine and Edible Alcohol"; ---Modify the scope of application and some contents of the density bottle method; ---Modify the scope of application and some contents of the Alcohol Meter Law; ---Modified the instrument conditions and some contents of gas chromatography; ---Modified the method name, scope of application and some contents of the digital density meter method; ---Modified Appendix A; ---Modified Appendix B; ---Added Appendix C. National food safety standards Determination of ethanol concentration in wine and edible alcohol

1 Scope of application

This standard specifies the method for determination of ethanol concentration (alcohol content) in wine and edible alcohol. The first method density bottle method is suitable for the determination of ethanol concentration (alcohol content) in wine and edible alcohol. The second alcohol meter method is suitable for the determination of ethanol concentration (alcohol content) in wine (except beer) and edible alcohol. The third method gas chromatography is suitable for the determination of ethanol concentration (alcohol content) in beer, wine and fruit wine. The fourth method, the U-shaped oscillating tube digital density meter method, is suitable for the determination of ethanol concentration (alcohol content) in wine and edible alcohol. The first density bottle method

2 Principles

Use the distillation method to remove non-volatile substances in the sample, and use the density bottle method to measure the density of the sample (alcohol aqueous solution) at 20°C. Consult the comparison table between the density of alcohol aqueous solution and ethanol concentration (alcohol content) to find the ethanol concentration (alcohol content) at 20°C.

3 Reagents and materials

The water is grade three water specified in GB/T 6682.

4 Instruments and equipment

4.1 Analytical balance. sensitivity 0.0001g. 4.2 All-glass still. 500mL. 4.3 Constant temperature water bath. temperature control accuracy ±0.1℃. 4.4 Density bottle with thermometer. 25mL or 50mL. 4.5 Volumetric flask. 100mL.

5 analysis steps

5.1 Sample handling 5.1.1 Preparation of carbonated wine samples After keeping the clean, dry 100mL volumetric flask and sample at 20°C, accurately measure 100mL of the sample into a 500mL distillation bottle. , rinse the volumetric flask with 50mL of water three times, merge the washing liquid into the 500mL distilling flask, add a few zeolites (or glass beads), and connect the serpentine condenser tube, use the original volume bottle used for sampling as the receiver (plus an ice bath), turn on the cooling water (the cooling water temperature should be lower than 15°C), slowly heat and steam Distill and collect the distillate. When it is close to the mark, remove the volumetric flask, cap and keep it in a 20°C water bath for 30 minutes, then add water (20°C) to the mark. degree, mix well, and set aside. ......
