6 Inspection Rules
6.1 Batching and sampling
6.1.1 Batching
The batch of the products shall be determined as per the corresponding rules specified
by the quality management department of the manufacturer.
6.1.2 Sampling
6.1.2.1 Products directly provided to the consumers: randomly sampling at least 12
minimum independent packages (total mass shall be no less than 500g) from each
batch of products; separately used for sensory, physical and chemical indicator,
aerobic plate count, coliform bacterial inspection, and sample-reserving.
6.1.2.2 Products indirectly provided to the consumers: insert the sampling probe into
5/6 position of each minimum independent package; take no less than 100g of sample
(the total mass of sample shall be no less than 1kg); separately used for sensory,
physical and chemical indicator, aerobic plate count, coliform bacteria inspection, and
sample-reserving.
6.2 Exit-factory inspection
6.2.1 The products can leave the factory only after the inspection department of the
enterprise inspect them qualified according to this Standard.
6.2.2 Exit-factory inspection items: sensory, fat, moisture, aerobic plate count, coliform
bacteria.
6.3 Type inspection
6.3.1 The type inspection items include all the contents in 4.2~4.4 of this Standard.
6.3.2 Generally, the type inspection shall be conducted once every 6 months. In one
of the following cases, the type inspection shall be carried out:
--- When there are significant changes on the raw materials, process, and
equipment;
--- When the production is restored after more than 6 months shutdown;
--- When there is a big difference between the exit-factory inspection results and
the normal production and inspection records.

Appendix A
(Normative)
Determination of Surface Oil-Fat-Content
A.1 Principle
After using the petroleum ether solvent to fully extract the creamer sample, evaporate
it. After removing the petroleum ether solvent, the remaining materials are the surface
oil-fat of the creamer; then obtain the surface oil-fat-content through weighing and
calculating.
A.2 Reagents
The reagents used for test include:
a) Petroleum ether: boiling range of 30°C~60°C;
b) Nitrogen: purity no less than 99.99%.
A.3 Apparatus
The apparatus used for test include:
a) Electric heating and drying oven: temperature control accuracy of ±1°C;
b) Analytical balance: sensitivity of 0.0001g;
c) Round-bottomed flask: volume of 100mL;
d) Conical flask;
e) Rotary evaporator.
A.4 Operation procedures
Take 8g (accurate to 0.0001g) of sample into the conical flask; add 30mL of petroleum
ether; fully shake for 5min; then use filter paper to filer it to the 100mL round-bottomed
flask, which has been pre-dried in the 105°C electric heating and drying oven to the
constant weight; the filtering slag shall be transferred into the original conical flask.
Then use 30mL petroleum ether to shake and extract for twice, the filtrate shall be
mixed into the 100mL round-bottomed flask. Place the round-bottomed flask in a rotary
evaporator, reduce the pressure and evaporate at the water temperature of 35°C~40°C
for 15min; use the filter paper to wipe the moisture outside the flask; blow dry with
nitrogen for 30min to remove the solvent. After the solvent is removed completely,
weigh the total mass of round-bottomed flask and surface oil-fat-content; then dry by
nitrogen till the total mass of round-bottomed flask and surface oil-fat-content is
constant.
A.5 Result calculation
Calculate surface oil-fat-content as per the Formula (A.1):
Where:
X – surface oil-fat-content of the sample, in g/100g;
W1 – mass of round-bottomed flask, in g;
W2 – total mass of round-bottomed flask and surface oil-fat, in g;
G – Sample mass, in g.
The calculation results shall retain one digit after the decimal point.
A.6 Tolerance
Each sample shall be made into two parallel samples; the result shall be expressed by
the arithmetic mean. The absolute difference between two independent determination
results obtained under the repeatability condition shall not exceed 5% of the arithmetic
mean.
