7.1.2 Sampling method and quantity
Randomly select samples from the finished products, and the sampling quantity shall
meet the requirements of inspection and retention.
7.2 Inspection classification
7.2.1 Factory inspection
7.2.1.1 Products shall be inspected batch by batch before leaving the factory. For
products of the same variety but in different packages, the inspection items that are not
affected by the packaging specifications and packaging forms can be inspected together.
7.2.1.2 Items for factory inspection include sensory, net content and moisture.
7.2.2 Type inspection
7.2.2.1 Products produced all year round shall be subject to type inspection once a year;
the type inspection shall be carried out in any of the following circumstances.
-- During the trial production and evaluation of new products;
-- When there are major changes in raw materials or processes that may affect
product quality;
-- When the production is resumed after suspension for more than one year;
-- When there is a significant difference between the factory inspection result and
the last type inspection result;
-- When the national supervisory authority requires a type inspection.
7.2.2.2 Type inspection includes all items of this standard.
7.3 Judgment rules
7.3.1 Factory inspection judgment rules. If all factory inspection items meet this
standard, the batch of products shall be judged to meet this standard. If there are
unqualified items in the factory inspection, samples can be taken for re-inspection. If
they are still unqualified after re-inspection, the batch of products shall be judged to be
non-compliant with this standard.
7.3.2 Type inspection judgment rules. If all the type inspection items comply with this
standard, the type inspection result is judged to comply with this standard. If there are

Appendix B
(Normative)
Alkalinity test method
B.1 Reagents
B.1.1 Hydrochloric acid standard solution (0.05 mol/L). It is prepared and calibrated
according to the method specified in GB/T 601.
B.1.2 Methyl orange indicator solution (0.1%). Weigh 0.1 g of methyl orange and
dissolve it in 70 °C distilled water, cool and dilute to 100 mL.
B.2 Apparatus
Acid burette. 25 mL.
B.3 Preparation of test specimen and test solutions
Prepare the test specimen and test solution according to the method specified in GB/T
12456.
B.4 Analysis steps
Pipette 50 mL of the test solution and place it in a 250 mL conical flask. Add two drops
of methyl orange indicator solution and titrate with hydrochloric acid standard solution
(0.05 mol/L) until a reddish color appears. Record the volume of hydrochloric acid
standard solution consumed. At the same time, perform a blank test with distilled water.
B.5 Presentation of analysis results
The alkalinity X of the biscuit is expressed as the number of grams of sodium carbonate
contained in 100 g of the specimen and is calculated according to formula (B.1).
where
X -- alkalinity, in grams per hundred grams (g/100 g);
c -- the actual concentration of hydrochloric acid standard solution, in moles per
liter (mol/L);
V1 -- the volume of hydrochloric acid standard solution consumed when titrating
Appendix C
(Normative)
Bulk density test method
C.1 Calculation method (arbitration method)
C.1.1 Apparatus
C.1.1.1 Vernier caliper. The accuracy is 0.02 mm.
C.1.1.2 Balance. The range is 1 g~500 g, and the accuracy is 0.1 g.
C.1.2 Analysis steps
Take a sample with a volume of at least 25 cm3, weigh its mass m (g) with a balance,
and then use a vernier caliper to measure its length, width and height respectively, and
calculate the volume V (cm3) mathematically.
C.1.3 Presentation of analysis results
The bulk density P of biscuits is expressed as mass per unit volume and is calculated
according to formula (C.1).
where
P -- bulk density, in grams per cubic centimeter (g/cm3);
m -- the mass of the sample, in grams (g);
V -- the volume of the sample, in cubic centimeters (cm3).
C.1.4 Allowable difference
The difference between two measured values of the same sample shall not exceed 2%
of the average value of the two measurements.
This method is only suitable for biscuits whose volumes can be calculated
mathematically.
