Foreword
Clause 5 and Clause 8 in this standard are mandatory; and the rest are recommended.
The consistent degree between this standard and the standard Sodium Bicarbonate (2002)
of Codex Alimentarius Commission is non-equivalent.
This standard replaces GB1887–1998 Food Additive - Sodium Bicarbonate.
Compared with GB1887–1998, the main changes of this standard are as follows.
- Adjust the indicator parameters correspondingly (3.2 of Edition 1998; Clause 5 of this
standard);
- Add the indicator and test method of content and whiteness of chloride (Clause 5 of
this standard);
- Improve the determination method of dry loss (4.3 of Edition 1998; 6.5 of this edition);
- Improve the determination method of pH value (4.4 of Edition 1998; 6.6 of this
standard);
- Improve the determination method of content of heavy metal (4.6 of Edition 1998; 6.8
of this standard);
- Improve the package and storage (Clause 6 of Edition 1998, Clause 9 of this
standard).
This standard was proposed by China Petroleum and Chemical Industry Association.
This standard shall be under the jurisdiction of Inorganic Chemicals Branch of National
Standardization Technical Committee (SAC/TC 63/SC 1) and National Food Additives
Standard Technical Committee (SAC/TC 11).

m - Value of mass of specimen, and the unit is g.
Take the arithmetic mean value of parallel determination results as the determination
result. The absolute difference of two parallel determination results shall not be more than
0.02%.
6.6 Determination of pH value
6.6.1 Instrument
PH meter. the accuracy is 0.02 pH unit.
6.6.2 Analysis steps
Weight 1.00 g ± 0.01 g of specimen; put it in a 250 mL beaker. Add about 100 mL of water
without carbon dioxide to dissolve the specimen. Determine within 10 min according to the
regulations of GB/T 9724 (since the time when adding the water).
6.7 Determination of arsenic content
6.7.1 Method summary
It is same as Clause 8 of GB/T 5009.76–2003.
6.7.2 Reagents
6.7.2.1 Hydrochloric acid solution. 1+3;
6.7.2.2 Arsenic standard solution. 1 mL of this solution contains 1µg of arsenic.
Weigh 1.00 mL of arsenic standard solution according to the requirements of HG/T 3696.2;
put it in a 100 mL bottle; use water to dilute to the mark; and shake it uniformly. Prepare

Standard whiteness plate.
6.12.2 Analysis steps
Use the regularly-calibrated standard whiteness plate to calibrate the working whiteness
plate. Adjust the whiteness meter to the working state; put the specimen in powder dish
