Foreword
Article 6.1 and 6.2 in Chapter 3 of this Standard are compulsory; the rest are recommended
articles.
The consistent degree between this Standard and Codex Stan 212–1999 Codex standard
for sugar is not equivalent.
This Standard replaces GB 317-1998 White granulated sugar.
Compared with GB 317-1998, the main changes of this Standard are as follows.
- In hygienic requirements, indicators items are increased or decreased basically
according to GB 13104-2005 “Hygienic standard for sugar”. it has added items for
microzyme and mould, it has deleted copper item; except for sulphur dioxide (SO2),
all items of hygienic requirements have directly cited the corresponding indicators in
GB 13104-2005; for sulphur dioxide (SO2), it has respectively formulated the indictors
equal to or more rigorous than those of GB 13104-2005, according to the grading level.
- In physiochemical requirements, modifications are made to the following items. the
conductive ash content, loss on drying, turbidity, and insoluble impurity of white refined
sugar; the superior-grade white granulated sugar’s reducing sugar content,
conductive ash content, colour value, turbidity and insoluble impurity; the first-grade
white granulated sugar’s colour value, turbidity and insoluble impurity; second-grade
white granulated sugar’s reducing sugar content, conductive ash content, loss on
drying, colour value, turbidity and insoluble impurity.
- It has changed the calculation and representation methods of turbidity. The unit is
changed from “degree” to “milli-attenuation unit” (MAU).
- In labels, it has added the contents of “Recommended to indicate quality warranty
period”.

as the requirements on labelling, packing, transportation and storage of white granulated
sugar.
This Standard is applicable to the white granulated sugar produced with cane or sugar beet
as the direct or indirect raw material.

3 Technical Requirements
3.1 Grades
White granulated sugar are divided into 4 grades. refined, superior-grade, first-grade and
second-grade.
3.2 Sensory requirements
3.2.1 Crystal grain shall be uniform and the grain size within the following range shall
scale. The measuring range is -30ºZ ~ +120ºZ; and calibrated by standard quartz tube. It
may select 3 methods.
a) Saccharimeter contains adjustable analyzer (disc type polarimeter); adopt
monochromatic light source (wavelength is between 540 nm ~ 590 nm); usually
adopt green mercury light or yellow sodium light.
b) Quartz wedge saccharimeter.
1) With monochromatic light source (wavelength is between 540 nm ~ 590 nm);
2) Incandescent lamp acts as the light source; an appropriate colour filter separates
the light with effective wavelength of 587 nm.
c) Saccharimeter contains Faraday coil as compensator; adopt monochromatic light
source (wavelength is between 540 nm ~ 590 nm).
Note. The saccharimeter with old sugar ºS scale can still be used; however, the reading in ºS
must be multiplied by a coefficient 0.999 71 to convert into ºZ.
4.3.3.2 Volumetric flasks
Volume. (100.00 ± 0.02) mL, to be calibrated by weighing (20.0 ± 0.1)°C water. The
volumes of volumetric flasks shall be ranged within (100.00 ± 0.01) mL; they can be used
without correction. When exceeding this range, it can only be used after it is corrected by
the correction corresponding to 100.00 mL.
4.3.3.3 Optical rotation sighting tube
Length. (200.00 ± 0.02) mm, it must have the qualification certification issued by authorized
measuring agency; or to be compared and inspected by a sighting tube that has such
qualification certification.
4.3.3.4 Analytical balance
Sensitivity is 0.1g.
4.3.4 Reagent
Distilled water. not containing optically active substance.
4.3.5 Calibration of saccharimeter
Saccharimeter shall be calibrated by the standard quartz tube verified to be acceptable by

4.4.4.3 Permissible error
The difference between the 2 determinations shall not exceed 15% of the mean value.
4.5 Determination of conductive ash content
4.5.1 Abstract of method
Conductivity reflects the concentration of ionization water dissolvable salts. Determine the
conductivity of known sugar solution; then work out the conductive ash content with

4.5.3 Reagent
4.5.3.1 Distilled water or deionized water. refined white granulated sugar must use distilled
water (distilled twice) or deionized water with conductivity to be lower than 2μS/cm. The
white granulated sugar of other grades can use distilled water with conductivity to be lower
than 15μS/cm.
4.5.3.2 0.01 mol/L potassium chloride solution. take analytically pure grade potassium
chloride; heat to 500°C; dehydrate for 30 minutes; weigh out 0.745 5g; dissolve into a 1
000 mL volumetric flask; add water to marking line.
4.5.3.3 0.002 5 mol/L potassium chloride solution. suck out 50 mL of 0.01 mol/L potassium
chloride solution; put into a 200 mL volumetric flask; add water to marking line. The
conductivity of such solution under 20°C shall be 328 μS/cm.

4.5.4.1 Determination
Weigh out 31.3g±0.1g of white granulated sugar; put into a dry and clean beaker; add
distilled water to dissolve; transfer to a 100 mL volumetric flask; wash beaker and glass
rod with distilled water for multiple times; the washing water also pours into the volumetric
flask; add water to marking line; stir up; use sample solution to wash the conductivity
electrode for determination of conductivity; dry and clean small beaker for 2 ~ 3 times; then
m1 -- mass of weighing bottle, in unit of gram (g).
4.6.3.3 Permissible error
